The M series speakers of the Walkman have always been a focus of market attention, with the market tested M0, M1, M2, followed by the well-known M360, M500, M3plus, and so on. In the first half of this year, two "heavyweight" products, M35 and M20, were added, making the same series of products a masterpiece. Since September, in addition to the glasses case and speaker M15, the all-new M16 has also been very eye-catching. What about this innovative and outstanding product? The following will explain them one by one for you.

1、 Metal material is used to create the box body

Compared to other products in the M series of the Wanderer, the M16 has a very innovative design and has also applied for a patent for its appearance (patent application number: 201030189714.4). Its body is made of aluminum alloy material, and the workmanship is very fine. The sandblasting effect on the surface can enhance the texture without getting fingerprints, and it is resistant to dirt and wear. The aluminum white box, combined with the black metal dust cover, is very harmonious. When placed on the desktop, it has a calm and atmospheric feeling, with extraordinary metallic charm that is irresistible.

There are not many metal speakers in the micro speaker market, mainly due to the high cost efficiency and large initial investment in developing metal molds. Therefore, most manufacturers rarely enter this field, but the advantages of metal materials are obvious. Taking M16 as an example, the aluminum alloy shell can provide effective protection for various parts inside the box, while the metal mesh can further protect the speaker unit. In addition, compared to wooden boxes, metal boxes can be made more luxurious and have an advantage in quality over plastic boxes, effectively avoiding the common "plastic sound" and "box sound" phenomena of plastic boxes, resulting in better sound quality performance. Although the M16 made of aluminum alloy metal carries a lot of weight in your hand, the 261 (width W) x 36 (height H) x 44 (depth D) mm "three circumference" and 0.33kg weight are very easy to carry, and will definitely not become a burden on your journey.

2、 New unit design layout

The M16 still belongs to the 2.0 system in terms of sound system, but it has the "4.1" feature in structure. Four full band speaker units and one low-frequency radiator are configured on the same side of the speaker, and the four speaker units are symmetrically distributed. This design can effectively utilize the speaker space, enhance the driving ability, and significantly improve the low-frequency effect, especially suitable for the field of portable mini speakers. This is also one of the patented technologies of Walkman (patent application number: 201020502249. X).

Firstly, let's take a look at the speaker unit. The M16 adopts a dual speaker design, with each channel equipped with dual 1.25-inch speaker units with an outer diameter of 32mm. Two speakers with the same structure, size, process, and performance characteristics are installed in each channel, which can improve the problem of small diameter and insufficient sound pressure of a single speaker unit, increase the volume, and provide better listening experience. And this design is the crystallization of the wisdom of the R&D personnel of the Wanderer. Building a reasonable acoustic structure on such a small box requires continuous debugging to ensure that the speaker units on both sides of the low-frequency radiator are in the same channel, thus forming a dual channel speaker system. The difficulty can be imagined. The engineers of the Wanderer went through multiple changes to achieve their current results, which is quite difficult.

2. Integrated low-frequency radiator

In order to further enhance low-frequency performance, the M16 adopts the patented technology of the Walkman - an integrated low-frequency radiator design (patent application number: 201020272755.4), which enhances the low-frequency effect of the small speaker. Its working principle is: when the active speaker inside the same box works, it compresses the air inside the box. When the air releases pressure, it drives the empty paper tray to move, thereby driving the air outside the box to produce sound. The function of a low-frequency radiator is actually to expand the diaphragm area that can drive air, thus effectively increasing low-frequency sensitivity. However, to achieve this design, multiple factors need to be taken into account, such as the matching of speaker unit and low-frequency radiator area and weight, box structure, and so on.

The low-frequency radiator of M16 includes an aluminum plate counterweight and an integral diaphragm, and the diaphragm integrates the folding ring and vibration basin, with good sealing effect, ensuring clean and pure sound quality. A piece of aluminum sheet is attached to the rear of the diaphragm, which can achieve better low-frequency lower limit and enhance low-frequency sensitivity by increasing weight. In order to achieve the best proportion of weight distribution, the R&D engineers of the Wanderer use special weight distribution adhesive to investigate the vibration quality. Different effects are tested by increasing or decreasing the weight distribution. After repeated debugging, the weight of the aluminum sheet attached to the low-frequency radiator is finally determined. The finalized product can ensure the best low-frequency effect without causing damage to the sound quality.

3、 Featured functional design

1. Single key volume adjustment technology

Of course, the magic of the M16 is not limited to this. In order to match the overall effect of the speaker, the engineers of the Walkman have "magically" created a single button volume adjustment technology (patent application number: 201020263845.7). Simply put, it is possible to increase or decrease the volume with just one button. You only need to press the Volume volume adjustment button briefly to increase the volume, and press it for a long time to decrease the volume, which is very convenient. The metal texture button combined with the blue indicator light aperture is also very dazzling.

2. Integrate USB power optimization function

For the design of USB power supply, the R&D personnel of Walkman have put in a lot of effort. Firstly, in order to enhance the USB playback effect, the M16 has applied USB power optimization function, which integrates USB bus power supply and USB streaming audio, and is equipped with a dedicated USB transmission cable to improve the efficiency of USB power utilization. Without damaging the USB interface, it can "draw" as much current as possible and transmit better sound.

3. Specially designed USB cable equipped

Traditional USB speakers are limited by USB power output, and the output power of the speaker is often small. In addition, ordinary USB cables are generally designed for low current, resulting in significant circuit losses during high current and high dynamic operation. Only by minimizing line losses as much as possible can the output power be effectively improved. To this end, the M16 uses a specially thickened USB cable that can shield against unwanted harmonic interference and reduce signal attenuation caused by ordinary wires. At the same time, the M16 also uses a high-efficiency Class D amplifier to provide sufficient power output, effectively improving the output power of the speaker and almost reaching the USB output limit. In addition, the dual channel speaker system consisting of four speaker units of the same size and functional characteristics has increased the output power of the miniature speaker, which also enables the rated output power of the M16 to reach 4W. The metal box also provides a good foundation for the speaker to produce good sound. With the special "4.1" structural design, the M16 has a clean and pleasant high-frequency sound, and the low-frequency radiator design also provides sufficient low-frequency sensation, resulting in a significant improvement in overall sound quality

4. Humanized design is widely adopted

The M16 also adopts many user-friendly technologies. When a USB cable is used to connect the computer and M16 speaker, the speaker will automatically receive USB power supply. The cool blue work indicator light circle will light up, and the system will enter standby mode. When you start playing audio files on your computer, the speaker also plays sound. When using an audio cable to connect external audio devices (such as MP3/MP4, mobile phones, etc.), the system will prioritize playing the audio files input by the AUX audio source, and the playback mode is very intelligent.

4、 Implementing playback with concise connections

Compared to the complicated wiring of traditional speakers, the M16 cable is very simple. It has a built-in USB digital sound card, integrates USB bus power supply and USB streaming audio, and only requires one USB cable to achieve power supply and data transmission functions, which is simple and practical. At the same time, the M16 also retains the AUX interface for easy connection to other external audio devices.

5、 Widely applicable

The M16 has reached a whole new level in both appearance design and sound quality performance. The all aluminum integrated portable speaker system design is very suitable for traveling together in a backpack, occupying very little space. Moreover, the walker has thoughtfully prepared a special flat velvet storage bag, which can protect the M16 from injury and prevent the metal body of the M16 from "accidentally injuring" other items in the bag, making it very convenient and practical.

When playing music indoors, daily pairing with laptops, PCs, MP3/MP4 players, CDs, or music phones can achieve perfect playback. The anti slip foot pad design makes it very stable to place on the desktop and effectively eliminates the vibration caused by the box's playback. The M16's textured exterior design creates a scenic spot that can seamlessly blend into your office and home life, bringing you endless musical pleasure.

For the micro speaker market, the addition of the M16, which is finely crafted, stylish and elegant in appearance, and has a calm and elegant temperament, will undoubtedly inject new colors into the portable speaker market. The special "4.1" system, combined with single button volume adjustment, integrated USB power optimization function, built-in digital sound card technology, powerful functions, easy operation, excellent sound quality. For those who pursue fashion and personality and crave good sound, what are you waiting for?
