Background

A sound box is a device that can convert an audio signal into sound, and is widely used in various public places such as squares, movie theaters, stages, or dance halls.

The existing sound box has various types: have bluetooth, wireless, wired bluetooth etc. can satisfy the needs of various public place sound broadcast and user's music broadcast, but current audio amplifier still has some weak points:

the sound waves of the existing sound box are uniformly distributed, such as: the sound waves are propagated in a horizontal direction or a vertical direction, and a listener feels that the sound is propagated from one direction, so that the stereo effect is poor, so that the sound waves of the sound box are often required to be transmitted, otherwise the sound effect of the sound box is influenced, for example, as follows: the performers or the members of the band on the stage monitor the singing or playing sound of the performers, and the performers or the members of the band cannot clearly hear the singing or playing sound of the band, so that the performers or the members of the band cannot well cooperate with or find out of the band, and the performance effect is seriously influenced.

It can be seen from this that: the prior art is deficient.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to prior art's defect, provide one kind and change sound wave radiation directive property, make sound radiation direction change, radiation range is wider, improves the reverse 360 degrees radiation type audio amplifier of product tone quality.

In order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a reverse 360 degrees radiation type audio amplifier, includes audio amplifier box and speaker, place the audio amplifier box in the speaker in, the opposite of speaker is equipped with the plane of reflection, the sound wave that the speaker was sent out produces the reflection on the plane of reflection and makes the sound wave form 360 degrees radiation diffusion and make the radiation range of audio amplifier sound enlarge.

Preferably, a reflection base is arranged below the sound box body, and the bottom of the sound box body is connected with the reflection base to form an integral structure.

Preferably, the reflecting surface is located above the reflecting base so that the reflecting base forms the reflecting base with the reflecting surface.

Preferably, the reflecting surface is opposite to the loudspeaker, so that the sound wave transmission direction of the loudspeaker is changed, the sound wave transmission range is wider, and the sound quality is improved.

Preferably, the internal mounting of audio amplifier box has power amplifier subassembly, the audio amplifier box promotes the speaker unit compressed air sound production in the audio amplifier box through power amplifier subassembly.

Preferably, the structure of the reflecting surface is: the reflecting surface is conical, conical or conical, so that sound waves of the loudspeaker can be emitted conveniently.

Preferably, the shape of the sound box body is a three-dimensional cylindrical shape, and the sound box body is not suitable for being flat in a large area.

Compared with the prior art, the utility model discloses a scheme contains following beneficial effect at least:

(1) the utility model discloses a 360 degree radiation type audio amplifier, including audio amplifier box and speaker, be equipped with the plane of reflection on the opposite of speaker, make the sound wave that sends out from the speaker produce the reflection on this conical plane of reflection, because this plane of reflection is conical plane of reflection, the sound wave direction of reflection becomes 360 degrees radiations, thereby play the effect of diffusion, through changing sound wave transmission direction, make its transmission range wider, increase the technique that sound wave radiated to 360 degrees in the audio amplifier, make the audience obtain relatively unanimous sense of hearing in most regions of space and can effectively enlarge the radiation range of audio amplifier sound, improve the stereophonic, improve the sound field, improve tone quality;

(2) the utility model discloses a speaker box body still embeds there is power amplifier module, after carrying out amplification treatment to audio signal through power amplifier module, promotes speaker unit in the speaker box body, and compressed air makes sound, makes its sound grow;

(3) the utility model discloses an audio amplifier box appearance is the bovine form, and appearance design is beautifully changed, and is visualized.
