Moving the subwoofer: The simple experience of the langqin M600

Rarely listening to portable speakers, mainly in terms of sound quality, performance is poor, unless it is a foreign brand, domestic portable speakers are usually inseparable from the "cheap"

Tags, but the portable speakers can be separated from the computer, and the advantages of independent use have also been favored by many people, and in the people's tireless improvement, this

Most of these speakers also have lithium, FM radio, built-in memory card and other functions. Fortunate to experience the Longines M600 wireless Bluetooth speaker, let me on the domestic portable speakers

There is a new understanding.


First, the appearance of appreciation

Usually not very concerned about portable speakers, so not very understanding of Long Qin, and later access to information to know that Long Qin is a focus on small-sized speaker and portable speaker development of the enterprise, but also more qualified companies, the pursuit of product quality and function .

Long Qin M600 speaker accessories: speakers, charging line, AUX line and instructions.

The speaker's exterior design is very distinctive. The design is similar to B&O A2. It is also a rectangular shape plus a hand strap. Maybe it's because of the built-in battery. It's still quite heavy, and it's like holding bricks.

The hand straps are cortical, and they are connected by rivets. The retro is very textured.

The keys are set on the top of the speaker, and the key surface is covered with a soft material. In addition to the commonly used playback control keys (pause/continue, previous, next), there are folder switch keys, battery mode, Bluetooth phone and M button (AUX and Bluetooth connection switching). Powerful is the first impression that the langqin M600 gave me. Imagine that the scene of holding it and answering the phone is also drunk.

The front cover of the LongMing M600 is made of a nylon fiber woven net, which is different from a normal plastic net. It also has a splash-proof function while being dust-proof. The waterproof splash function is very practical in the open air. If it is waterproof, it will be better. I think a little bit more.

The side frame is made of plastic material. It is necessary to pay attention to the fact that it is often carried away, or it is difficult to see after scratching. The speaker can be placed horizontally and vertically, and there is a large piece of soft anti-slip mat at the bottom.

On the back of the speaker, the hollowed out cavities on both sides are two passive passive units. It looks like the low frequency performance of the speaker is very good.

Open the rubber plug, inside the TF card socket, power switch key, AUX plug, MircoUSB interface and USB power outlet. The langqin M600 can read TF content and support folder switching. There is also a feature that can be used as a mobile power source. This is also a rare feature of other speakers. Just did not expect to set the power switch here, using a little inconvenience.

Second, the sound quality experience

(Photo quoted from the official)

According to the official, the Longines M600 is a 2.1-channel speaker system that consists of a 3-inch woofer, two 2-inch full-range speakers, and two 90-by-60mm passive units. Texas Instruments' 5-series chips guarantee long-term performance. Piano M600 Speaker 17W rated power output. The 17W power is obviously ample for this small speaker! The 2.1 channel also makes the speaker more applicable scene, not only can listen to music, in watching movies, playing games, and even square dancing will have a better performance.

The Longines M600 supports both AUX and Bluetooth connectivity, which is also the current mainstream connection method.

When I first started listening, I felt bored. It may be because of the new speakers. Especially for small speakers, after a few days of continuous auditioning, the sound improved a lot, and the low frequency performance was very good. Close to the passive unit, the energy loss is also smaller, there is no feeling of paste, fairly clean, low frequency is also the characteristics of this box, it is worth moving a subwoofer.

The performance of the other two full-range speakers can only be said to be quite satisfactory. It is not as good as the low-frequency display. The LongMing M600 is suitable for playing slow shakes, DJs, and dances. Later I changed the slow shake of Soho. Some dance music is suitable for Long. The piano M600 expresses the way.

Built-in 8800 mAh battery, the official said that can be played continuously for 7 hours, this did not go to verify, my personal experience, quite anti-use, continuous listening for a few days there is electricity, another special feature is that Charges devices such as mobile phones, but it can only be done while it is off.

The nominal output can reach a maximum current of 2A, and the measured value is 1.82A. The accuracy and attenuation of the instrument are dropped. This 2A is still worth definitive. This is a speaker and a portable power supply. This concept is very good and it is indeed a user-friendly design.


Third, the conclusion

The LongMing M600 changed my “cheap” impression of domestic portable speakers, with meticulous workmanship, full low-frequency elasticity, strong long-term battery life, support for TF card expansion, and it can also be used as a portable power supply, which is also the hallmark of domestic speakers. Powerful, but I don't know why I didn't add Longin's consistent FM radio function. The Bluetooth connection also allows speakers to better connect with other devices, such as micro-projectors, and TVs, while enjoying big movies and playing games. The time brings a nice sound experience. Another use, I think you also think, is to dance square dance, Long Qin M600 can open the voice to a large without breaking the sound, jumping square dance horse is too suitable.

Magnetic Scale

Displacement sensor, also known as linear sensor, is a linear device belonging to metal induction. The function of the sensor is to convert various measured physical quantities into electricity. In the production process, the measurement of displacement is generally divided into measuring the physical size and mechanical displacement. According to the different forms of the measured variable, the displacement sensor can be divided into two types: analog and digital. The analog type can be divided into two types: physical property type and structural type. Commonly used displacement sensors are mostly analog structures, including potentiometer-type displacement sensors, inductive displacement sensors, self-aligning machines, capacitive displacement sensors, eddy current displacement sensors, Hall-type displacement sensors, etc. An important advantage of the digital displacement sensor is that it is convenient to send the signal directly into the computer system. This kind of sensor is developing rapidly, and its application is increasingly widespread.
