Abstract
The utility model discloses a tone chamber arrangement which comprises a body, wherein the inner part of the body is provided with a loudspeaker accommodating chamber and a back tone chamber, the body is also provided with a front tone chamber, the loudspeaker accommodating chamber is communicated with the front tone chamber, the body is provided with a tone outlet and the front tone chamber is communicated with the environment through the tone outlet. The front tone chamber is positioned in the middle part of the back tone chamber, and the seal end of the front chamber and one side wall of the body form a narrow passage. Consequently, the back tone chamber is divided into a left and a right back tone chambers which are communicated with each other. Compared with the prior art, the utility model has the characteristics of simple structure, reasonable structure, good tone quality of sound playing, better bass effect, etc.
Description
Technical field
The utility model relates to a kind of sound cavity apparatus of forming sound play device that is used for cooperating with miniature loudspeaker.
Technical background
When Audio Processing chip or other music circuit are tested, the loud speaker of playing back music need be installed in the sound cavity apparatus.Existing sound cavity apparatus is to be made of integrated body.Described body is a cavity, and its inside is provided with the loud speaker containing cavity, is used to lay loud speaker.Offer some cellular senders on the bottom surface of described loud speaker containing cavity, the end face of described loud speaker containing cavity and the inwall of body form the back sound chamber than large space.When laying loud speaker, need sound can be sent smoothly the front end placed face down of loud speaker from sender.People generally believe that sound chamber, back has a significant impact tonequality at present, should be big as much as possible.But but there is a defective in existing sound cavity apparatus, i.e. the sound that sends by this sound cavity apparatus point often, and the sound playing effect is bad will directly to have influence on the acoustic processing effect that detects Audio Processing chip or other music circuit.
The utility model content
The purpose of this utility model is: at the deficiencies in the prior art, provide a kind of rational in infrastructure, sound cavity apparatus that sound playing is effective.
In order to solve the problems of the technologies described above, technical solution adopted in the utility model is: a kind of sound cavity apparatus, comprise body, offer loud speaker containing cavity and sound chamber, back in the described body, sound chamber before also offering on the described body, described loud speaker containing cavity is communicated with described preceding sound chamber, offers sound mouth on the described body, and described preceding sound chamber is in communication with the outside by described sound mouth.
The sound chamber can be positioned at the centre in sound chamber, described back before described, and a sidewall of its blind end and described body forms a slype, thereby with sound chamber after the sound chamber is divided into left and right two that interconnect after described.
The bottom of described loud speaker containing cavity with described before can offer a through hole on the shared sidewall in sound chamber.
Can offer wire hole on the bottom surface of described body.
The cylindrical loud speaker containing cavity sidewall circle of described loud speaker containing cavity on can be by the end that is vertically set on described body becomes, and the height of described loud speaker containing cavity sidewall is lower than the sidewall of described body and the sidewall in preceding sound chamber.
Sound chamber, described back is to be formed at interval by the madial wall of body and the lateral wall in preceding sound chamber and the lateral wall of loud speaker containing cavity.
Can be provided with one group of described loud speaker containing cavity, preceding sound chamber, sound chamber, back, sound mouth, wire hole in the described body, thereby form the monophony structure.
Can symmetrically be provided with two groups of loud speaker containing cavities, preceding sound chamber, sound chamber, back, sound mouth, wire hole in the described body, thereby form the dual track structure.
In technique scheme, sound chamber before the utility model increases, thereby under the situation of sound chamber after the assurance to the tonequality influence, overcome people's technology prejudice, the defective of sound point in the prior art is eliminated in the sound chamber before utilizing, and has strengthened bass effect, can obviously improve tonequality.In addition, the utility model also adopts the structure in sound chamber, two back, guarantees audio reproduction quality preferably.The utility model both can be realized monaural structure, can be applied to the dual track structure again, thereby realized the 3D audio, was applicable to the broadcast of present chord sound.Characteristics such as therefore, relative prior art the utlity model has simple and reasonable for structurely, and sound playing tonequality is good, and particularly bass effect is better.
Description of drawings
Accompanying drawing 1 is the monophony structural front view of the utility model sound cavity apparatus;
Accompanying drawing 2 is the upward view of Fig. 1;
Accompanying drawing 3 be among Fig. 2 A-A to cutaway view;
Accompanying drawing 4 is the front view of the dual track structure of the utility model sound cavity apparatus.
Embodiment
Below in conjunction with Figure of description and specific embodiment the utility model is described in further detail.
Embodiment 1:
Present embodiment is a kind of monophony structure of the present utility model.
With reference to figure 1,2,3, a kind of sound cavity apparatus comprises body 2.Described body 2 is a cavity body structure.
Offer loud speaker containing cavity 4, sound chamber, back and preceding sound chamber 6 in the described body 2.
Described loud speaker containing cavity 4 is to be enclosed by the cylindrical loud speaker containing cavity sidewall 40 on the bottom surface that is vertically set on described body 2, and the height of described loud speaker containing cavity sidewall 40 is lower than the sidewall 20 of described body 2 and the sidewall 60 in preceding sound chamber 6.
The bottom of described loud speaker containing cavity 4 with described before offer a through hole 7 on the shared sidewall in sound chamber 6, thereby described loud speaker containing cavity 4 is communicated with described preceding sound chamber 6, offer sound mouth 8 on the described body sidewall 20, described preceding sound chamber 6 is in communication with the outside by described sound mouth 8.
Offer wire hole 1 on the bottom surface of described body 2.
The utility model is placed the face down of loud speaker in use, thereby sound chamber 6 before sound passes spreads out of from sound mouth 8.The lead of loud speaker passes from described wire hole 1, and adopts encapsulant with this wire hole 1 sealing, thereby guarantees the sealing in sound chamber, back 3,5, also promptly guarantees tonequality.
Embodiment 2:
The difference of present embodiment and embodiment 1 is: present embodiment is the dual track structure, be interior symmetrical be provided with two groups of little sound chamber A, B of body, they are by formations such as loud speaker containing cavity, preceding sound chamber, sound chamber, back, sound mouth, wire holes, and its structure is identical with embodiment 1.
Present embodiment 2 can be realized the 3D audio, is suitable for playing the chord music.
