The sound box provided by the utility model has the advantages of higher sensitivity, better sound quality and small volume.
Description
Technical field
The utility model belongs to the electronic product field, is specifically related to a kind of atmospheric pressure compensating audio amplifier.
Background technology
Current, development along with each building block technique of consumer electronics product, especially aspect tv product, the appearance of LED screen has brought a brand-new industrial revolution to TV industry, and audio amplifier becomes the bottleneck of whole industry, at present, in order to prevent the sound wave short circuit, a lot of audio amplifiers all adopt the sealed-box type structure.Though the sealed-box type audio amplifier has advantages such as low frequency sound reproduction distortion is little, damping is big, but also has the defective that is difficult to solution:
1, the audio amplifier damping is big, and inner and outer air pressure can not get balance, influences the sensitivity of sound;
2, do not have effective atmospheric pressure compensating way, the audio amplifier volume is too huge.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of atmospheric pressure compensating audio amplifier is provided, and the sensitivity of audio amplifier described in the utility model is higher, and tonequality is better, and the audio amplifier volume is little.
Its technical scheme is as follows:
A kind of atmospheric pressure compensating audio amplifier, comprise casing and be located at loud speaker on the casing, the box house space sealing, in casing, be provided with middle interlayer, be provided with elastic component between middle interlayer and casing, middle interlayer is first subspace and second subspace of two separate sealings with the separated by spaces of box house, has pressure reduction between first subspace and second subspace, described loud speaker is located in first subspace, the difference in volume that the volume of second subspace is produced when shaking greater than loud speaker.
The technical scheme of the further refinement of aforementioned techniques scheme can be:
Described elastic component is a spring, and this spring is arranged in described second subspace.
The two ends of described spring are pressed on respectively between described middle interlayer and the casing, and the air pressure of described first subspace equates that with the air pressure in the external world air pressure in described second subspace is lower than ambient pressure.
Described second subspace is positioned at the top of described first subspace.
Interlayer comprises rigid layer and elastic layer in described, and the periphery of rigid layer is connected with described casing by elastic layer.
Described casing comprises casing internal layer and casing skin, is connected (described connecting portion is a cushion) by connecting portion between casing internal layer and the casing skin, forms vacuum layer between casing internal layer and casing skin.
In sum, the utility model has the advantages that:
1, Mi Feng casing effectively prevents sound wave short circuit and sound wave interference, can obtain purer bass;
2, be provided with middle interlayer between first subspace and second subspace, and elastic component acts on the middle interlayer, when loud speaker shakes, be used for the vibrations that the balance loud speaker is produced, particularly, because there are draught head in first subspace and second subspace, middle interlayer can bear the pressure to the second subspace direction, spring is given pressure of middle interlayer, and interlayer is issued to balance in the effect of draught head, spring pressure in making, and the sensitivity of loud speaker is higher;
3, second subspace is positioned at the top of first subspace, in the middle interlayer dynamic balance factor, also is subjected to the influence of spring and the middle gravity of interlayer own;
4, by middle interlayer and elastic component the air pressure of loud speaker is carried out balance, make the volume of audio amplifier littler;
5, casing is a double-decker, connect by cushion between two layer box bodies, and between two layer box bodies vacuum layer, can effectively reduce the vibrations of casing itself.
