There have been similar to Bose Soundlink mini, Creative Sand Blaster Roar, B & O beoplay A yuan this level even higher product positioning. Edifier also to blending one, launched M7, the official price of 1,398 yuan. 样机来源 : 厂商送测样机类型 : 市售量产机是否商业关系 : 是 M7 styling elements from the 7 / 80s of portable tape recorders, long handle is remarkable shape characteristics, retro feeling, coupled with the rounded rectangle shape, minimalist style. M7 handle made of aluminum alloy, the handle has a slight curvature of the top surface, surface anodized and brushed with a hard metal, but not sharp on hand. Handle can be placed in 45-degree and 90-degree position have a clear sense of scale, after the handle down can use as a scaffold, speaker of the directional change in the desktop use, the effect will be better.

2 - 面罩 Masks made of aluminum alloy processing, hollow diamond pattern, this texture can not rely on common Stamping, milling precision equipment should be out, these hollow pattern edge to maintain a tough knuckle, but not paddlers, the surface layer of very fine It sandblasted, which gives a very special feeling. Larger hollow mask through which air is high, not too much sound barrier. - 拆掉铝面罩 - 打开声学腔体 Masks casing can see plastic box. Interior is divided into three parts, about an acoustic chamber, the middle part of the circuit and the battery is placed [official data: when three watt-hour lithium polymer rechargeable batteries]. - 高音扬声器 - 低音扬声器 - 被动振膜 - 拆掉铝面罩

3 Edifier Edifier M7 Bluetooth Speaker - Remove the aluminum mask In the Edifier's official website, the words "with 'best to listen to portable audio' for the idea" in the acoustic design, M7 is really different from the general portable speaker designs. It uses a double crossover design, 19 mm silk membrane tweeter and 70 mm woofer, the usual design is the use of a full-range speaker. Double crossover design will lead to a more complex design, the division itself is the most difficult. Small size speakers to enhance the low frequency usually means is to use passive diaphragm. M7, a total of three racetrack passive diaphragm, a former two later. Passive role of the diaphragm is to enhance the total area of the diaphragm, in order to promote a greater volume of air to form a stronger sense of the amount of low frequency, why is it called passive diaphragm? Because it is not actively driven. Initiative is that of the two bass speakers, will compress the gas chamber when the speakers are working, thereby driving the passive diaphragm work, as did the air spring. Since like a spring, it will have delayed reactions, passive diaphragm can significantly enhance the sense of low volume, but also reduce the transient and dynamic low frequency, which is the total of the advantages and disadvantages of this design, good design will reduce the disadvantage Impact. As mentioned earlier, the handle can tilt bracket allows the cabinet, in fact, this design will also affect lowfrequency performance. Has passive radiation diaphragm forms an angle with the desktop into a semiopen space, air will be more apparent squeeze, so this design will change the low-frequency performance, low-frequency hearing sense becomes slightly force of some.. -TI TAS5707 数字功率放大器芯片 - 意法半导体 STM8L151 MCU 芯片 -BB PCM1808 ADC 和其他芯片 -CSR8645 蓝牙模块 M7 and R1900TV and other speakers using the same technology platform, which uses a digital amplifier technology plus digital divide. M7 is used in two TAS5707, TAS5707 is Texas Instruments produced a 20- watt stereo digital power amplifier, because to use the digital divide, so the use of the two channels, respectively, a total of four drives 4 speakers. Digital divide bring technological advances to see, now this technology has brought them to a portable speaker. In addition, there is Bluetooth 4.0 module and ADC and other peripheral components. Bluetooth support apt-x, which requires the transmitter device also supports apt-x to be enabled. Apt-X supports a lot of devices, such as Samsung, Sony, HTC, VIVO, Lumia so many models. When apt-x codec, Bluetooth sound quality will be better reflected in the resolving power. About sound Bluetooth device, as well as ordinary SBC and apt-x difference, please read " 10 smart devices with Bluetooth sound quality evaluation report "[Author: Soomal ] article.

4 Functional design is minimalist, in addition to Bluetooth connectivity outside [can use NFC pairing], there is only a set of linear input. As for the internal sound card, built-in player, etc. were all no. M7 has a USB port, is to give mobile emergency charging. Manipulation is very simple, three buttons at the top of the cabinet, power supply / switch, volume plus and minus buttons. Because fewer buttons and opening the box and covered with a rubber cover, M7 can achieve IP54 level waterproof and dustproof, general dripping M7 will not cause harm. From the design point of view M7, it does have a unique place, set aside part of the appearance and technology, for the sound of the building, with a heart. Edifier in trying to make a move R1x00, exactly the same technology platform. Of course, limited to "portable", one-piece design, separation must not be good. Digital amplifier of high efficiency, but also makes this technology platform migration becomes possible, measured display, in the case of full power, medium volume under use, battery life is 6-8 hours, basically to meet the time out needs - 和 Bose SoundLink - 和创新 Sound Blaster Roar[ 声霸锣 ] - 和 B&O Beoplay A2 Actual use, we refer to the three well-known products as a comparison. Namely Bose Soundlink mini, Creative Sand Blaster Roar, B & O beoplay A2, these three products represent the three schools Bluetooth portable speaker, can simply be summarized as portable faction, functionalist and sound quality pie. Portable fuction pursuit of excellent portability, small size, of course, does not depend on Soundlink mini sound, the Sound Blaster is a typical representative of the functionalist Creative Sand Blaster Roar, it functions very much, this is also the company innovative technology in audio equipment accumulation inseparable, these two products is currently the best selling premium Bluetooth speaker. And beoplay A2 is also used double crossover design, larger, portability will suffer badly. M7 positioned closer beoplay A2, the volume is also larger. Advantageously bulky acoustic design, but the volume is large does not mean that the sound quality will be better. 本文的相关书签 : M7 漫步者 Edifier 蓝牙移动电源微型音箱无线音频自由的音频数码设备移动数码智能手机 Windows 图集

5 With the cast was more open acoustic design, M7 compared the sound quality Soundlink mini and Creative Sand Blaster Roar has an overwhelming advantage, M7 obviously much better resolving power and sound layering, especially in the high frequency band, if you use linear input, this gap will widen even more obvious, feel the sound big circle, form significantly more plentiful. In the low-frequency part, occupied the volume of natural advantages M7, low frequency has a better sense of texture and volume, in the face of rapid percussion, M7 control over much better. M7 tuning style closer Soundlink mini, maintained a soft warm sense of hearing, but a lot of high frequency should be bright, this is a very appealing style. And compared beoplay A2, M7 has better frequency performance, sound more thick. beoplay A2 sound design uses a double-sided, one side of a channel, so in terms of like force significantly weaker than the M7, but control and resolving power is significantly better than the other two. These speakers have a common characteristic, the separation is not ideal, the sound field is very small, one-piece design common problem. On the application scenario, M7 and these products are not the same, M7 although there handle, but I believe the people carrying it out for a walk no more, but in small gatherings, such as what to a picnic, it very appropriate. It is more scenarios or indoors, in the range of room, can be very easy to move. Because the sound quality advantages, it is more suitable as background music playback device, in a non-serious listening environment, it is the "most serious". M7 is the first attempt, technically, it succeeded. New technology platform for the transformation of the sound is very clear, it is feasible on desktop speakers, portable speakers equally feasible. Many indicators M7's sense of hearing is more like a good performance desktop speakers, its resolving power and layering considered on the portable speaker is the optimum level, whether it is Bluetooth mode or linear input. On desktop speakers, but also not bad. It also tried a more advanced manufacturing process, M7 Edifier manufacturing process should be one of the most complex products, but it looks very low key not kitsch. As for market performance, it remains to be seen, this is the most expensive portable speaker Edifier products, direct competitors are international big-name, quality advantage M7 will overwhelm their big premium brand it? 本文的相关书签 : M7 漫步者 Edifier 蓝牙移动电源微型音箱无线音频自由的音频数码设备移动数码智能手机 Windows 图集
