Description

Be applied to multichannel audio amplifier subassembly of integrative equipment of microphone audio amplifier

Technical Field

The utility model belongs to the technical field of the technique of the integrative equipment of microphone audio amplifier and specifically relates to a be applied to multichannel audio amplifier subassembly of the integrative equipment of microphone audio amplifier.

Background

The microphone and sound box integrated equipment has both the sound box function and the microphone function, and the microphone converts a sound signal into an energy conversion device of an electric signal; the sound equipment is a set of audio-frequency sound production device which is combined by electrical equipment to produce sound.

The sound production cavity structure of the integrative equipment of current microphone audio amplifier is too single, leads to its tone quality of sending to be relatively poor, and in addition, the structure that microphone and audio amplifier are combined together can make both influence each other in function, and the sound that the audio amplifier produced spreads easily and produces the public address and then arouse the problem such as howling for the microphone, and the use that gives the user is experienced not well.

Disclosure of Invention

To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a be applied to multichannel audio amplifier subassembly of the integrative equipment of microphone audio amplifier.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a be applied to multichannel audio amplifier subassembly of integrative equipment of microphone audio amplifier, includes the audio amplifier body, this internal cavity that is provided with of audio amplifier, the side of audio amplifier body encircles in proper order and is equipped with first fretwork, first recess, second fretwork and second recess, main cavity speaker and main cavity body sound producing component are installed respectively to first fretwork and second fretwork punishment, install first pair cavity speaker and the vice cavity speaker of second on first recess and the second recess respectively, audio amplifier body, main cavity speaker and main cavity body sound producing component form a sealed main cavity room, first pair cavity speaker with first recess forms sealed first pair cavity room, the vice cavity speaker of second with the second recess forms sealed second pair cavity room.

Further, the main cavity sound producing part is a main cavity vibrating diaphragm or a cavity loudspeaker.

Furthermore, the plane of the horn opening of the first auxiliary cavity loudspeaker and the plane of the horn opening of the second auxiliary cavity loudspeaker respectively form a first included angle and a second included angle with the plane of the horn opening of the main cavity loudspeaker, and the ranges of the first included angle and the second included angle are 30-140 degrees.

Furthermore, the plane where the first hollow is located corresponds to the plane where the second hollow is located.

Furthermore, the sound box body is provided with a wire passing hole communicated with the cavity.

Adopt above-mentioned scheme, the beneficial effects of the utility model reside in that: the sound-producing device comprises a closed main chamber, a first auxiliary chamber and a second auxiliary chamber which are distributed on two sides of the main chamber and are closed independently, wherein the three components which are completely independent and independently have independent closed spaces are combined to form a chamber combination which can produce sound independently;

first pair cavity and second pair cavity set up relatively stagger each other with main cavity loudspeaker and main cavity body vibrating diaphragm relative setting, and the microphone miaow head is installed just at the top of audio amplifier main part and is located both looks vertically central points to it influences the squeal that leads to have weakened the structure that microphone miaow head and audio amplifier are combined together mutually.
