Abstract
The utility model pertains to the technical field of electric-acoustic products, and especially relates to a loudspeaker module which comprises a first shell and a second shell that combined into an integral body. A single loudspeaker is accommodated and fixed in a cavity formed by the first shell and the second shell. The single loudspeaker is used to divide the cavity into two cavities including a front vocal cavity and a rear vocal cavity. Compressed melamine sound absorption cotton is arranged in the rear vocal cavity. The melamine sound absorption cotton is provided with an avoidance portion for avoiding other components. The compressed melamine sound absorption cotton is arranged in the rear vocal cavity, and the melamine sound absorption cotton is provided with a lot of micropores, so the volume of the rear vocal cavity can be expanded, the low-frequency performance can be effectively reduced, the passband can be expanded, the total quality factor can be improved, and the problem of poor low-frequency effect with existing loudspeaker modules can be solved.
Description
Technical field
The utility model belongs to electro-acoustic product technical field, relates in particular to a kind of loud speaker module.
Background technology
Loud speaker module is a kind of energy converter, can convert electrical energy into acoustic energy radiate, parts indispensable in electro-acoustic product, mainly comprise shell, in the cavity surrounding at shell, accommodate and be fixed with loudspeaker monomer, loudspeaker monomer is divided into the front operatic tunes and two cavitys of the rear operatic tunes by cavity.The low frequency part of rear operatic tunes major effect sound, the low frequency part of sound is very large on the impact of tonequality, in order to improve tonequality, common way is the volume of the operatic tunes after increasing, but the increase that the volume of the rear operatic tunes can not be unlimited, along with the development of technology and the raising of consumer demand, to acoustical behavior, require more and more higher, and the volume of the operatic tunes is relatively little after existing loud speaker module, low-frequency effect is poor, has therefore affected the tonequality of sound.
Utility model content
The purpose of this utility model is to provide a kind of loud speaker module, is intended to solve the poor problem of existing loud speaker module low-frequency effect, can improve the tonequality of sound.
The utility model is to realize like this, a kind of loud speaker module, described loud speaker module comprises: shell, the accommodating loudspeaker monomer that is fixed with in the cavity surrounding at described shell, described loudspeaker monomer is divided into the front operatic tunes and two cavitys of the rear operatic tunes by described cavity, is provided with the melamine acoustical cotton of processing via compression in the described rear operatic tunes.
As a kind of improvement, the compression factor scope of described melamine acoustical cotton is 3:1～10:1.
As further improvement, on described melamine acoustical cotton, be provided with for dodging other parts and dodge portion.
As further improving, described in the portion of dodging be the gap structure that is opened in described melamine acoustical cotton sidepiece.
As a kind of improvement, described shell comprises the first housing and the second housing being combined as a whole, and described the first housing and described the second housing surround described cavity jointly.
The loud speaker module that the utility model provides comprises shell, the accommodating loudspeaker monomer that is fixed with in the cavity surrounding at shell, loudspeaker monomer is divided into the front operatic tunes and two cavitys of the rear operatic tunes by cavity, in the rear operatic tunes, be provided with the melamine acoustical cotton of processing via compression, because be provided with the melamine acoustical cotton of processing via compression in the rear operatic tunes, on melamine acoustical cotton, there is a lot of micropores, can play the effect of the rear operatic tunes volume of expansion, can effectively reduce low frequency performance expansion pass band, total quality factor have been improved, solved the poor problem of existing loud speaker module low-frequency effect, can improve the tonequality of sound.

Fig. 2 is the structural representation before melamine acoustical cotton compression of the present utility model;
Fig. 3 is the structural representation after melamine acoustical cotton compression of the present utility model;
Wherein, the 10, first housing, the 11, second housing, 12, loudspeaker monomer, 13, melamine acoustical cotton, 13a, melamine acoustical cotton, 13b, melamine acoustical cotton, 131, dodge portion.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, this loud speaker module comprises the first housing 10 and the second housing 11 being combined as a whole, in the cavity that the first housing 10 and the second housing 11 surround, accommodate and be fixed with loudspeaker monomer 12, loudspeaker monomer 12 is divided into the front operatic tunes and two cavitys of the rear operatic tunes by cavity, in the rear operatic tunes, be provided with the melamine acoustical cotton 13 of processing via compression, compression factor scope is 3:1～10:1, conventional have a 3:1, 4:1 and 5:1, on melamine acoustical cotton 13, be provided with the portion of dodging 131, this is dodged portion 131 13 cuttings of the melamine acoustical cotton after compression is formed, be used for dodging other parts of the rear operatic tunes.
Because be provided with the melamine acoustical cotton 13 of processing via compression in the rear operatic tunes, on melamine acoustical cotton 13, there is a lot of micropores, can play the effect of the rear operatic tunes volume of expansion, can effectively reduce low frequency performance expansion pass band, total quality factor (having determined the size of amplitude under same frequency) have been improved, solve the poor problem of existing loud speaker module low-frequency effect, can improve the tonequality of sound.
For the ease of understanding, in conjunction with Fig. 2 and Fig. 3, the compression process of acoustical cotton is described:
First get a thicker melamine acoustical cotton 13a, as shown in Figure 2, compress processing, obtain size identical, the melamine acoustical cotton 13b of reduced down in thickness, as shown in Figure 3.Melamine acoustical cotton 13a before compression, because density is smaller, is easy to tear, and is not suitable for engineering volume production, and the melamine acoustical cotton 13b density after compression increases, and the successful of intensity deduction and reduction low frequency performance promotes.
The loud speaker module that the utility model provides comprises the first housing and the second housing being combined as a whole, in the cavity that the first housing and the second housing surround, accommodate and be fixed with loudspeaker monomer, loudspeaker monomer is divided into the front operatic tunes and two cavitys of the rear operatic tunes by cavity, in the rear operatic tunes, be provided with the melamine acoustical cotton of processing via compression, on melamine acoustical cotton, be provided with for dodging other parts and dodge portion; Because be provided with the melamine acoustical cotton of processing via compression in the rear operatic tunes, on melamine acoustical cotton, there is a lot of micropores, can play the effect of the rear operatic tunes volume of expansion, can effectively reduce low frequency performance and expand pass band, improve total quality factor, solved the poor problem of existing loud speaker module low-frequency effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
