Another Milestone in the Intelligent Audio Industry: Palm Audiovisual Audio Foreword The development of wireless transmission technology has intensified the continuous progress of wireless audio! The development from Bluetooth 4.0 technology to Bluetooth 4.1 technology has not only progressed from the quality of wireless transmission, but also greatly improved the power consumption. Audio from the early 2.0, 2.1 as the mainstream of the speaker, to now booming Bluetooth audio has brought new ideas to people's lives! In 2015, it was known as the first year of China's smart hardware development. Bluetooth audio naturally flourished. Audio not only uses audio as its main selling point, but also forms various types of rare goods through many cross-border combinations: audio with touch screen becomes a small computer; audio with charging treasure also meets people's demand for mobile power; The NFC near-field data interaction sound; the Bluetooth stereo that comes with playback software, etc. are all more functions than the user's appeal for listening. Today, we took everyone together and approached a set of radio, alarm clock, children's teaching aids, car navigation in one of the sound. Exaggerating, the sound is a small computer or mobile phone. And its main function is from the portable, shocking sound quality to a variety of functions, all refreshing. Such a high level of intelligence is believed to bring you different feelings. Shenzhen Zhangxian Electric Co., Ltd. produced this palm audio-visual audio, there are no similar products in the market so innovative, not only in the sound of the sound of the building itself, or in a highly intelligent system operation, people see To the future potential of this product. Shenzhen Leading Electric Co., Ltd. is a professional company specializing in audio products. Its products are sold overseas and have strong R&D capabilities. Today, through the palm of this "audio + Internet" products to experience the strength of the first science and technology! Refreshing design Audio's innovative design has always been a sign that audio manufacturers are constantly pursuing progress. The palm of your hand is very sharp and you can't even believe it is a sound. Since the palm is not yet on the market, Xiao Mo gets the engineering machine. The packaging design is not excellent, but it is also very reliable. The palm of the 5 screen palm is not too big, the packaging is not natural, the outside set of paper introduces some basic information of the palm of your hand: Internet audio is palm positioning, good-looking, nice, easy to use, fun Naturally this product's selling point! Based on the Internet, sound, naturally, the integration of various music software. The side of the package gives you a powerful introduction to the audiovisual capabilities of your palm: HiFi Audio, Live TV System, Pocket Watch System, Driving Tools System, Internet Radio/FM System, Smart Voice, Digital Alarm Clock, Children's Entertainment Education, Charging Po, China Elderly entertainment and so on. Perhaps you can't believe that there are so many useful features in a little palm, but this is not a gimmick. The palmtop audiovisual configuration has a 5-inch touchscreen display with a black front design, and the obvious bottom three feature touch buttons identify it with Android. The black foam tightly wraps the body in the package, avoiding bumps. The audiovisual accessories are also very simple, an instruction manual, a Micro-USB power Adapter and a 3.5mm audio Cable. Most sounders will have one such audio cable. The accessories are very exquisite workmanship, white accessories and black palm viewing is quite atmospheric. The front of the palm is equipped with a 5-inch touch screen, 5 inches is suitable for consumers, and the single-hand grip is very comfortable. The three big kings of Android system can't miss the keys. The black front is equipped with three touch keys. There is a front camera in the middle of the front side of the palm of the audience. Although the resolution of 1.9 million pixels is not high, it also meets the user's basic shooting needs. After the computer is turned on, the palm-watching desktop displays a clock. The unlocking method is somewhat different from the Android system's unlocking method. This is a customized system for palm-swapping, and the system is described in detail later. Just looking at the positive side of the palm of your hand, you can't seem to have anything to do with the sound, and the back of the palm of your hand can be said to be completely acoustic, with a floating sound hole in the middle and a floating sound hole design that is patented. The surface is the palm of the name. The entire surface is treated as a hole-like musical wave cloud that looks very delicate. The surface of the palm of the audience uses a matte gold plated effect. There are four small tentacles around it, which allows the user to spread the volume when placed. The upper left corner is the rear camera, which is comparable to the mobile phone's rhythm. The entire rear design is very similar to the acoustic cone effect. Interface, palm-view audio configuration with external button switch, 3.5mm headphone cable, Micro-USB charging interface and mobile charging USB output, palm-view audio and video built-in lithium battery, through the USB interface 5V/1A output can be mobile phones, etc. The equipment is powered. This design is quite practical. At the top of the palm, the three buttons are the volume control button and the pause button. There is no up/down switch button. This is a shortcoming. There are some certification marks at the bottom of the palm of your hand: FCC and CE certifications are all available and the security is guaranteed. There is also a microphone port on the side next to the palm of your hand to allow users to control their voices and use recordings! The thickness of the palm and the thickness of the one dollar coin, the matte surface feels good, and the edges are polished to handle the cutting process. Typhoon Gold's body color adds a bit of extravagance to the entire sound. Throughout the palm of the audio-visual design, it is like a combination of mobile phones and audio, but the sound heritage of the innovative concept than the mobile phone is even better. Play sound, palm power is extraordinary As an audio product, the quality of extroverted products is naturally a concern to consumers and a place where manufacturers can make efforts. It is the first manufacturer of audio equipment in the country and has good natural skills in this area. Palm audio and video as a network + audio, the audio function in the end how? Will you just make a gimmick and get a nondescript product? This also needs to be analyzed from the hardware structure of its audio. From the explosion of the palm of the hand, we can see that there are more than a dozen layers of internal design structure with high precision. Built-in two high-power amplifier units, the traditional Bluetooth audio due to the thickness and space constraints, the power amplifier unit is often small, the sound quality can not be a good interpretation. The size of 1855829mm in the palm of your hand ensures a reasonable layout of the high power amplifier unit. Hand-held large cavity design, coupled with ultra-thin high-power speakers, to ensure maximum sound quality of the high-fidelity output, can output the perfect sound quality. If the audio-visual cavity design and ultra-thin high-power speakers are not enough to demonstrate their performance in terms of sound quality, then the unique low-frequency passive unit design can be said to be very powerful! The low-frequency passive unit adopts a three-level structure. The outer layer is a decorative aluminum alloy metal sheet, and the middle is a low-frequency vibration coil. A heavy iron is arranged inside, which is similar to the design of a large-scale passive unit. The combined passive unit has good elasticity by hand pressing, which ensures that the passive unit can play more excellent sound quality at the low frequency output, similar to the traditional paper cone design. For the audio performance of this palm-speaking audio system, it is very good to detect its low-frequency performance through some drums, cello music and some familiar native albums. "Drum Sister," "Sad City," and "Hummel Gets the Rockets" are the classic examples of conventional low-frequency sound detection. The performance of palm-saw at the low frequencies is excellent, and the low-frequency dive is very deep, thanks to the vocalization potential of the low-frequency passive unit configured on the back. In terms of subwoofer, the volume is not only large, there is no sense of tearing, and the roundness of the sound is comparable to the passive unit of the 2.1 audio independently configured. In the audition of “Ah Zuo Jieâ€, the vocal part, long low frequency part, is eye-catching and expresses a sense of immersion. In the high-middle-frequency part, the performance of palm-sightedness is also good enough. In the high-frequency part, there is no sharp feeling of deafness, and the sound line rises simply and agilely, plus the role of the passive unit, the entire high-frequency part appears to be somewhat thick and thick. In the midrange part, through Gimhae's "The Pride" and Leona Lewis's "angel", the audition, the splitting of the instrument, and the rendition of the voice are very good. For such a high-fidelity sound, the strength of the first technology is indeed not small. watch for. As an Internet + audio equipment, whether it is from the exterior design, or from the sound quality performance of the sound, the palm of the audience is sufficient for the needs of the family. Of course, it's not just that. You know, this is an Internet-based audio system. Intelligence is another big feature of it. Next, it's time to look at the bottom of the palm to see how intelligent it is! Rich software resources create different smart audio Internet + audio is not without precedent, from a small street to several smart audio test point of view, palm viewing is one of the very good one! In the process of constructing the Internet + audio intelligence, we must first consider how to integrate more applications, and how to create applications with multiple functions. Palm audio and video as outstanding performance, software strength naturally does not show weakness! The Android system is almost an intelligent management system that all intelligent devices currently use, which is also based on its open system and its mature application market. Palm audio and video is of course using the Android system as a software resource management system. Although Android, palm-saucer based on Andrews 4.3.3 custom optimization of many functional modules. The lock screen mode is the first system for palm-viewing and customization. In the lock mode, the palm-watching and audio-visual function is turned on, the dial's dial design is more user-friendly, and the two display modes are horizontal and vertical. It is convenient for users to place two kinds of locks according to their own preferences. Screen layout. Palm's deep customization of the fast desktop system is another very good place. By customizing several circular shortcut area interfaces, the user can set the most frequently used function applications in the shortcut application area according to his own needs, so as to facilitate the search for applications. In addition to the custom transformation of the native Android system. The most advantage of a smart product is the combination of diverse application software. The success of Apple's mobile phone on the one hand because of its combination of hardware and software, on the other hand is based on the IOS system development of a variety of powerful applications, palm audio-visual Internet + smart audio in the application of extension can be said to be very unique! In the integration of music software, the palm-based audio-visual development based on the Android system can certainly be compatible with all music software on the market. Compared with the traditional Bluetooth stereo, palm audio and video without external mobile phones and other devices to collect music sources, only need to operate the music software through the touch screen interface. Very convenient! Audio's thirst for music is naturally self-evident, palm-watching built-in rechargeable lithium battery, can independently operate for more than 18 hours, the user needs to download music to the palm of your hand, you can use this excellent sound everywhere HAPPY, because The volume of the palm of the audience is large enough, so a small square dance, the use of palm audio and video as a sound device to play "the most dazzling national wind" such as the Square Dance Divine Comedy, naturally nothing difficult. Palm has a rear-facing 5 megapixel camera that can be used as a monitor with built-in housekeeping software. This feature is very sharp. For example, an elderly person in the family with a child is prone to an accident. At this time, using palm-saw audio and video as a monitor, you can monitor your home's every move by using mobile phones and other devices (downloading surveillance software) at any time. Hand-held audio-visual pre-installed many pre-installed children's learning software, so that the palm of your hand turned into a teaching aid for children to learn. Several built-in apps passed a few days of tests and were very good. Children at home also liked to use it. People’s pursuit of the radio is always just needed, especially when the old people are all right, listening to the radio is always excellent. Naturally, Palm Audio also has a built-in radio app. Through testing, the palm-viewing radio function does not require the configuration of a headset as an antenna to implement the broadcast function. Hand-held audio and video built-in antenna makes palm-viewing portable listening to a nearby broadcast, a key search function is very powerful! Voice search is currently a very popular mobile phone function, palm audio and video naturally also built a third-party voice recognition software: Ling rhyme voice, through the voice control to achieve application startup and other functions are under control, through the trial, voice control accuracy is also very outstanding. Palm audio and video as a sound device, as a car monitor, of course, is no problem, in addition, palm audition also has a GPS positioning function, the system downloads navigation software, through the palm of the audience to go out of the navigation weapon is no problem Compared to mobile phones, it sounds louder, more comfortable to use, bigger and more secure. Handheld audio and video as a home Internet audio equipment, far beyond our imagination, speaking from the object of use, it can not only become a child's entertainment learning machine, when the driving recorder, but also to become the elderly radio, the most important is Can also become a home monitoring device. For palm-viewing other software features, not repeat them here. Hardware and battery life tests For an Internet smart visual sound: palm audio and video hardware configuration may not seem so important, enough to use, after all, it is not a smart phone! Then through some specific parameters to understand the audio and video hardware configuration and personalized interface functions. From the storage capacity point of view, the palm of the 8GB space is indeed a lot of embarrassment, usually download a movie and the song seems a bit stretched. The system uses less than 2GB of space by default, giving users only 6GB more. And palm-viewing does not support memory expansion, it seems a bit regrettable. The manufacturers also have built-in 8GB memory card, body storage 8G 10 8G memory card 16G, which is very intimate! Palm audio and video using Spreadtrum's SC7731 quad-core CPU, the average consumer may not understand this CPU, from the run point of view, the CPU can go to over 12,000 points, Samsung, millet, HTC and other mobile phones, purifiers and other smart products are used This CPU. Performance can also be! After all, the demand for hardware from palm audio is not high. In terms of GPU and screen resolution, the 5-inch display has a screen density of 240 DPI, which is accompanied by a 1080×720 pixel, which is not as good as the 1080P and 2K screens of mobile phones, but the display effect is not bad. If you want to play some small games, such as chess, it is no problem, of course, as a sound, playing games is not its main business. From the test of color display on the screen, there is no light leakage on the screen, and the brightness of the display is dark. Of course, this will save more power. The overall picture display is still more subtle, although there is a slight sense of grain, but it does not affect the use. Master Lu's comprehensive running points are more than 17,000 points. As a sound device, this is nothing representative of value. It's impossible to compare with a mobile phone. One of the most important functions is to use it as a charging treasure to support the 5V/1A output standard. It adapts to almost all mobile phone input standards. When the mobile phone is out of power, you can use your palm to overexpose it. Very good. Of course, palm-viewing does not have a fast charge function. The audio-visual life time is still worthy of recognition. Just listening to music and listening to the radio, the battery life is no problem for 18 hours. If the child is playing a game and the screen is lit, it will not take half a day. problem. to sum up The palm-sounding Internet audio system as a sound device can be said to be a bold innovation. The use of audio as a carrier to integrate the genes of the Internet has brought a lot of convenience to consumers! Not only that, but the palm of the hand is designed to carry more features: it can be an alarm clock, it can be a charging treasure, it can be a monitor, it can be a children's aid, it can be a radio, it can be a smart music player. Device, can be a car navigation, can be a driving recorder. It is the Internet gene that gives the sound more imagination. In terms of sound, its shocking high-fidelity sound effects can satisfy the 100-square-meter high-pitched music experience. For a sound of less than RMB 1,000, palm-snapping has a lot of surprises. In the audio industry, cross-border integration is a trend, and palm video will become a milestone in this era.
