Abstract
The utility model relates to a sound cavity configuration, it includes the host computer body, a speaker, a back lid, the host computer body is equipped with a cavity, is provided with the speaker in the cavity, leaves the space between the speaker and the host computer body, forms the ante -chamber, and a back lid then sets up in the speaker below, with host computer body fixed connection, leaves the space between back lid and speaker, forms the back cavity, be provided with the leading note structure in the ante -chamber of the host computer body. The utility model discloses a setting of leading note structure can be play away the energy of sound wave smoothly, has avoided the problem of sound wave in the in -fighting of sound intracavity, can carry high tone quality effectively.
Description
Technical field
The utility model relates to audio amplifier, particularly relates to a kind of sound-guiding structure of sound chamber.
Background technology
Along with science and technology constantly develop, existing end product.As communicating terminal intercom, complete machine presents more and more thinner trend.Intercom complete machine is thinning means that its spatial volume also reduces accordingly, to such an extent as to the utilizable operatic tunes effectively utilize space also fewer and feweri.The quality of the intercom operatic tunes on the effect of call has conclusive impact.As same sound source, the tonequality that same loud speaker runs in the different operatic tunes may differ larger.Therefore, in order to the acoustical quality making the loud speaker of intercom obtain, then, under the condition of existing certain operatic tunes volume, how raising tonequality, seems important especially.
As shown in Figure 1, loud speaker 2 is placed in main body 1 front, after be bonnet 3.The operatic tunes both sides in main body 1 front do not have sound-guiding structure, and the sound wave part that loud speaker 2 periphery sends is lived by the cavity shelves in main body 1 front, and airflow obstruction in-fighting, has a strong impact on the acoustical quality of product.
Summary of the invention
For the deficiency of existing sound chamber scheme, the utility model devises a kind of audio cavity structure, and the energy of loud speaker can reasonably play out by this structure, and then the effect of the tonequality improved.
Another object of the present utility model is to provide a kind of audio cavity structure, this structure simple structure, is easy to realize, and is convenient to install and use.
For achieving the above object, the purpose of this utility model is achieved through the following technical solutions.
A kind of audio cavity structure, it comprises a main body, a loud speaker, one bonnet, described main body is provided with a cavity, is provided with loud speaker in cavity, leaves space between loud speaker and main body, form ante-chamber, one bonnet is then arranged on below loud speaker, is fixedly connected with main body, leaves space between bonnet and loud speaker, form back cavity, in the ante-chamber that it is characterized in that described main body, be provided with sound-guiding structure.
Described sound-guiding structure, arranges the periphery with ante-chamber.
Described sound-guiding structure, is leading note face, plays out smoothly can make sound wave.
Further, described sound-guiding structure, its cross section is arcuate structure, and sound wave is played out according to specific direction.
Further, described sound-guiding structure, its cross section is acute angle-shaped structure.
Further, between described bonnet and main body, be provided with fluid sealant, to be sealed by back cavity, avoid dust to enter in back cavity.
The energy of sound wave, by the setting of sound-guiding structure, successfully can play out, avoid the problem of sound wave in-fighting in sound chamber, effectively can improve tonequality by the utility model.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is the structural representation that the utility model is implemented.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to shown in Fig. 2, as Fig. 2 shows a kind of audio cavity structure for the utility model realizes, this audio cavity structure includes main body 1, loud speaker 2, bonnet 3.Wherein, main body 1 is provided with a cavity, loud speaker 2 is provided with in cavity, the periphery of loud speaker 2 is fixed on main body 1, leaves space before loud speaker 2 and between main body 1, forms ante-chamber, one bonnet 3 is arranged on below loud speaker 2, be fixed together with main body 1, between bonnet 3 and loud speaker 2, leave space, form back cavity.
At the periphery of loud speaker, main body 1 is provided with sound-guiding structure 4.Sound-guiding structure 4 is generally leading note face, plays out smoothly can make sound wave.And leading note face 4, its cross section is generally arcuate structure, enables sound wave play out smoothly according to specific direction.
Between bonnet 3 and main body 1, be provided with fluid sealant, to be sealed closely by back cavity, the back cavity of loud speaker and ante-chamber separated completely.The sound of back cavity and ante-chamber can be made not interfere with each other, extraneous water or dust also can be made can not to enter back cavity by ante-chamber, thus reach the effect of water proof and dust proof.
Like this, the energy of sound wave, by the setting of sound-guiding structure, successfully can play out, avoid the problem of sound wave in-fighting in sound chamber, effectively can improve tonequality by the utility model.
This structure simple structure, is easy to realize, is convenient to installation and the use of loud speaker.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
Claims (6)
