Wall hangs sound box to say wall hangs sound again, it is by sound source input equipment, signal amplifier (work put) and wall hangs type loudspeaker composition, it is a set of sound system. Wall hanging sound box: It is a kind of ultra-thin sound box of useful combination by rock painting and sound box, also can be called flat panel sound box. The sound principle of the wall hanging speaker: after the excitation (driving body) to arouse the sound plate in the tortuous wave and sound.

We know sound box is an integral part of sound, but sound is by include power put, all over equipment (include pressure limit device, effect device, equalizer, VCD, DVD, etc.), loudspeaker (sound box, horn) mixing station, microphone, show equipment and so on add up a set of intact system.

Wall-mounted speaker construction: Driver. It's the heart of a flat speaker. The key to drive planning is that its useful stroke is very small, generally not more than 2m/m2; Secondly, the voice coil part should not be too heavy, or the high-frequency part will have more severe distortion. Planning requires light components, small volume, and large magnetic force. According to the above elements, we choose high magnetic data, and the general magnetic beam density should be greater than 10000 Gauss, so as to have better performance.

Sometimes in order to progress the output, using the two drive body or four driving body to improve output sound pressure, and use multiple driver body, a better frequency response curve can be obtained, as for the use of several drive the intrusive body depends on the vibration plate area and weight, Joe micrograms of stirring device, the selection of high-tech intelligence to ensure the product high quality quality, ensure the use of product safety.
