Description
Technical field
This utility model belongs to electronic device field, is specifically related to the loudspeaker of a kind of rear audio cavity structure.
Background technology
The arrival of information age, in market, the demand of electro mechanical devices increases severely, and its development prospect is good, brings to the life of people a lot of excellent simultaneously. Audio amplifier, is commonly called as loudspeaker, refers to be transformed to audio signal a kind of equipment of sound, and popular saying refers to carry power amplifier in speaker main casing or subwoofer casing, itself is played back out sound by audio amplifier after audio signal is amplified process. The development of audio amplifier brings very big convenience to vast user, makes the free life of people become colourful, adds the sentiment of life, and a lot of megastore, meetings etc. simultaneously are all used, it is seen that purposes is very big. By the structure of audio amplifier it can be seen that after audio amplifier inside loudspeaker the structure in sound chamber sound is critically important. The audio amplifier form being currently on market is various, development increasingly quicker, but internal structure distribution design or existing defects, and the design of rear sound chamber is unreasonable, and volume is relatively big, brings very big inconvenience to user, is worth correcting.
Utility model content
The purpose of this utility model is that the loudspeaker providing a kind of rear audio cavity structure in order to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of loudspeaker of rear audio cavity structure; including horn bulb, speaker, rear sound chamber, containment vessel; described horn bulb is internally provided with described speaker; described horn bulb rear end is provided with leak; described rear sound chamber it is provided with between described horn bulb rear end and described speaker; described horn bulb front end is provided with acoustic aperture; front sound chamber it is provided with between described horn bulb front end and described speaker; being connected to rubber washer between described horn bulb and described speaker, described horn bulb outer end is connected to described containment vessel.
In said structure, it it is a kind of electric energy a kind of conversion equipment of converting sound to, when different electron energies reaches coil, it is interactive with the magnetic field of Magnet that coil produces a kind of energy, this interaction causes described loudspeaker vibration, because electron energy changes at any time, the coil of loudspeaker can move forward or backward, therefore the described speaker of loudspeaker will and then move, this this action makes the air density degree in described front sound chamber and described rear sound chamber produce change and produce sound, internal described rubber washer ensures the described front sound chamber of trumpet and the sealing in described rear sound chamber.
In order to improve the reasonable structure of loudspeaker further, by being adhesively fixed between described horn bulb and described containment vessel, described speaker and described horn bulb are fixed by screw.
In order to improve the reasonable structure of loudspeaker further, described rubber washer and described horn bulb are by being adhesively fixed, and described leak and described acoustic aperture are connected by holing with described horn bulb.
In order to improve the reasonable structure of loudspeaker further, described rear sound chamber is connected formation by described horn bulb with described speaker.
In order to improve the reasonable structure of loudspeaker further, described front sound chamber is connected formation by described horn bulb with described speaker.
Have the beneficial effects that: this trumpet reasonable in design is compact, well make use of inner space, and is provided with seal washer, be effectively guaranteed the sealing of inside, improve the sounding effect of loudspeaker; Outer cover intensity is high, and safety is high.
Accompanying drawing explanation
Fig. 1 is the front sectional view of the structure in sound chamber after special loudspeaker described in the utility model.
1, horn bulb; 2, speaker; 3, rear sound chamber; 4, leak; 5, front sound chamber; 6, acoustic aperture; 7, containment vessel; 8, rubber washer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, a kind of loudspeaker of rear audio cavity structure, including horn bulb 1, speaker 2, rear sound chamber 3, containment vessel 7, described horn bulb 1 is internally provided with described speaker 2, produce change by the described speaker 2 density degree in described front sound chamber 5 and described rear sound chamber 3 and produce sound, described horn bulb 1 rear end is provided with leak 4, described rear sound chamber 3 it is provided with between described horn bulb 1 rear end and described speaker 2, extrude described front sound chamber 5 and described rear sound chamber 3 and produce different pressure, sound is sent thereby through described acoustic aperture 6, described horn bulb 1 front end is provided with acoustic aperture 6, front sound chamber 5 it is provided with between described horn bulb 1 front end and described speaker 2, it is connected to rubber washer 8 between described horn bulb 1 and described speaker 2, ensure the described front sound chamber 5 of trumpet and the sealing in described rear sound chamber 3, described horn bulb 1 outer end is connected to described containment vessel 7, protect the safety of described speaker 2.
In said structure, it it is a kind of electric energy a kind of conversion equipment of converting sound to, when different electron energies reaches coil, it is interactive with the magnetic field of Magnet that coil produces a kind of energy, this interaction causes described speaker 2 to vibrate, because electron energy changes at any time, the coil of loudspeaker can move forward or backward, therefore the described speaker 2 of loudspeaker will and then move, this this action makes the air density degree in described front sound chamber 5 and described rear sound chamber 3 produce change and produce sound, internal described rubber washer 8 ensures the described front sound chamber 5 of trumpet and the sealing in described rear sound chamber 3.
In order to improve the reasonable structure of loudspeaker further; by being adhesively fixed between described horn bulb 1 and described containment vessel 7; described speaker 2 is fixed by screw with described horn bulb 1; described rubber washer 8 and described horn bulb 1 are by being adhesively fixed; described leak 4 and described acoustic aperture 6 are connected by holing with described horn bulb 1; described rear sound chamber 3 is connected formation by described horn bulb 1 with described speaker 2, and described front sound chamber 5 is connected formation by described horn bulb 1 with described speaker 2.
Of the present utility model ultimate principle, principal character and advantage have more than been shown and described. Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; described in above-described embodiment and description is that principle of the present utility model is described; under the premise without departing from this utility model spirit and scope; this utility model also has various changes and modifications, and these changes and improvements both fall within the scope of claimed this utility model.This utility model claims scope and is defined by appending claims and effect thing thereof.
