Abstract
The utility model provides a sound box which comprises a sound box body and a speaker body which is arranged inside the sound box body. The speaker body comprises a supporting frame, a diaphragm and a suspension edge which is connected between the supporting frame and the diaphragm, wherein a flexible outer elastic edge which can enable a resonance chamber to be formed between the sound box body and the supporting frame is arranged between the sound box body and the supporting frame. By means of the flexible outer elastic edge arranged between the sound box body and the supporting frame, the resonance chamber is formed between the sound box body and the supporting frame, so that the sound box not only overcomes the drawback caused by resonance of the speaker body and the sound box body in the prior art, but also can improve tone quality effect of the sound box.
Description
Technical field
The utility model relates to the audio amplifier technical field.
Background technology
As shown in Figure 1, existing audio amplifier, its loud speaker body 10 comprises: support 11, vibrating diaphragm 12 and be connected support and vibrating diaphragm between outstanding limit 13.Wherein, support 11 directly is fixedly connected with sound box (not drawing among the figure).When the loud speaker sounding, when promptly the diaphragm of loudspeaker 12 is followed air motion with outstanding limit 13,, therefore can make to form resonance between loud speaker body 10 and the sound box because loud speaker body 10 is fixed with sound box, influence the audio amplifier acoustical quality.
The utility model content
For this reason, the utility model technical problem to be solved is: a kind of audio amplifier is provided, when making the loud speaker pronunciation, does not produce resonance between sound box and the loud speaker body, and can further improve the audio amplifier acoustical quality.
So; The utility model provides a kind of audio amplifier; Comprise the loud speaker body that sound box is inner with placing sound box; The loud speaker body comprise support, vibrating diaphragm and be connected support and vibrating diaphragm between outstanding limit, wherein, between sound box and support, be provided with and can make between sound box and the support the flexible outer bullet limit that forms resonator.
Said outer limit one end that plays is connected with sound box, and the other end is connected with support.
The described audio amplifier of the utility model; Play the limit outside the flexibility through between the support of sound box and loud speaker body, being provided with; Make and between sound box and support, formed resonator; Not only overcome the drawback that loud speaker body and sound box resonance are brought in the prior art, and can improve the audio amplifier acoustical quality.

Fig. 2 is the sketch map of audio amplifier sectional structure shown in the utility model embodiment;
Fig. 3 is an audio amplifier explosion type sectional structure sketch map shown in Figure 2;
Fig. 4 is an audio amplifier plan structure sketch map shown in Figure 2.
Embodiment
Below, in conjunction with accompanying drawing the utility model is described in detail.
Extremely shown in Figure 4 like Fig. 2; Present embodiment provides a kind of audio amplifier; Comprise sound box (not drawing among the figure) and place the inner loud speaker body 20 of sound box; Loud speaker body 20 comprises: support 21, vibrating diaphragm 22 and be connected support and vibrating diaphragm between outstanding limit 23, wherein, between sound box and support 21, be provided with and can make between sound box and the support 21 the flexible outer bullet limit 30 that forms resonator.
A said outer end that plays limit 30 is connected with sound box, and the other end is connected with support 21.Connection described here can be to be fixedly connected, and also can be bonding.
Because the flexible outer adding that plays limit 30; Make and formed a resonator between sound box and the loud speaker body; When loud speaker pronounced, the loud speaker body can move by the accompany movement air-flow in the lump, the unnecessary harmonic wave that has produced when so both having overcome the resonance of loud speaker body and sound box; Because of the resonator that forms between sound box and the loud speaker body, effectively improve the acoustical quality of audio amplifier again.
Sound box can be made shapes such as circular, square according to actual needs.
The described audio amplifier of present embodiment; Play the limit outside the flexibility through between the support of sound box and loud speaker body, being provided with; Make and between sound box and support, formed resonator; Not only overcome the drawback that loud speaker body and sound box resonance are brought in the prior art, and can improve the audio amplifier acoustical quality.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
Claims (2)
1. audio amplifier; Comprise the loud speaker body that sound box is inner with placing sound box; The loud speaker body comprise support, vibrating diaphragm and be connected support and vibrating diaphragm between outstanding limit; It is characterized in that, between sound box and support, be provided with and make bullet limit outside the flexibility that forms resonator between sound box and the support.
2. audio amplifier according to claim 1 is characterized in that, said outer limit one end that plays is connected with sound box, and the other end is connected with support.
