Comparison of the relationship between mural sounds

Relationship between mural acoustics and mural loudspeaker

Mural speakers are part of mural sounds, not just mural sounds, and should not be confused. As we all know, the loudspeaker is an indispensable part of the sound system. However, the audio system consists of power amplifier and peripheral devices (including voltage limiter, effector, equalizer, VCD, DVD, etc.). ), sound box (sound box, speaker) mixer, microphone, display device, etc.

The structural characteristics and driving of wall speaker 1. It is equivalent to the heart of a flat speaker. The key point of driver design is that its effective stroke is very small, generally less than 2m/m2; Secondly, the voice coil part should not be too heavy, otherwise there will be serious distortion in the high frequency part. The design requires light weight, small volume and large magnetic force. Based on the above factors, we use high magnetic materials. Generally, the magnetic beam density should be above 10000 gauss to have better expressive force. Sometimes in order to improve the output, two drivers or four drivers are used to improve the output sound pressure, and a better frequency response curve can be obtained by using multiple drivers. As for how many drivers are used, it depends on the size and weight of the diaphragm. Tuomicrogram adopts high-tech intelligent exciter to ensure the safety of the product under the condition of ensuring the high-quality sound quality of the product.

2. Vibrating plate. Just like human vocal cords, it plays a decisive role in timbre, sound volume and fluency, so it plays an important role in the flat speaker behind the exciter.

3. Suspension system. The vibration principle of flat-panel speakers is completely different from that of general traditional speakers. Generally, the traditional horn adopts the piston vibration mode; The vibration of the flat speaker is random, so its lowest vibration frequency is not only one point, but more than ten points. For a well-designed flat speaker, there are even more than twenty points. Moreover, its driving point is not in the center, because the maximum sound pressure and the smoothest frequency response curve can not be obtained in the center, but in the best position of node vibration, plus four suspension points with the ratio of 1:9, to form a reasonable suspension system.

4. Backplane. The design of the back shell must take into account the problem of increasing acoustic diffraction by opening holes in the back shell, because the flat speaker is a wave vibration. Similarly, its back will produce the same sound pressure (only in different phases), so there must be a window to increase the sound radiation, so it will have better directivity and will not produce different sound effects because of the different positions of the listener. Toug fully considers this point in product design, making sound quality in the leading position in the industry.

2/kloc-at the beginning of the 20th century, domestic flat-panel audio manufacturers such as Madison (MDS) flat-panel audio, Shenzhen Hualong Sheng Di (Rolovo) Company, Sannuo, Cai Tong and Yingjue EOGO flat-panel audio were established respectively! Subsequently, Shenzhen Tuoweige (TVC flat-panel audio: CCTV ten sets of reports-singing oil painting) company was established separately. In 2009, Madison (MDS) occupied the Chinese mainland market like a dark horse. trait

1, no speaker pronunciation

Plane art speakers have no speakers, but produce sound by exciting bending waves in the resonance board. It is a flat 180 pronunciation, which is different from the traditional speaker's 40 ~ 90 pronunciation. Let you hear harmonious and powerful voices anywhere in the listening space, and there are "emperors" everywhere!

2. Sound quality effect

The transmission sensitivity of sound quality is extremely high, the directivity is wide, the sound field is evenly distributed, the sound quality is clearer, the transient response is good, and the depth is strong. The principle of vocalization makes the audience sound "dull near, clear far away, sound everywhere, music everywhere", thus realizing the auditory enjoyment of "no distance, all space"!

3, strong practicability

Thanks to the latest high-tech materials, the speaker has the characteristics of strong light sensitivity, pleasant tone, portability, heat resistance, dustproof, waterproof, intelligent, power saving, environmental protection and space saving. The perfect combination of time and space allows you to "listen to a song and watch a picture".

4. Personalized decoration

Buyers can freely choose the style and style of products according to the decorative effect and spatial layout of their own space, such as calligraphy and painting, wedding photography, family photos and so on! Due to the adoption of new technology, the product is ultra-thin (3cm). The combination of painting and sound is an excellent match for home decoration!

5. Don't disturb your neighbors.

Because DS flat-panel artistic sound is pronounced around the space of 180, the range of sound can be controlled, and the sound spreads by bending waves and scattering, without affecting neighbors!

6. Lower power consumption

The product is specially designed for family leisure. Its driving part has low power and high speaker sensitivity, which can save electricity 1/4!
