Description
Technical field
It the utility model is related to audio frequency apparatus technical field, and in particular to a kind of stereo set.
Background technology
In order to pursue more preferable tonequality, shock sense is shown, magnificent strong, plentiful deep, most of audio class productions at present
Product (such as audio amplifier, intelligent meeting equipment, player, earphone) are both provided with bass horn.Bass horn produces the principle of sound
It is that electric coil vibrates together with loudspeaker film, promotes the air vibration of surrounding, thus loudspeaker produces sound.The conversion of energy
Process is to be converted to magnetic energy by electric energy, then is converted to mechanical energy by magnetic energy, then is converted to sound from mechanical energy.
Most of existing bass horn is to adopt to be screwed, and bass horn occurs directly to contact or every one with structural member
The very thin foam of layer, it is easy to transfer vibrations to structural member and whole electronic product, electronic product produces with ground or support member
Raw vibration, thus occurs serious interfering noise, influences the tonequality of electronic product and good experience.Also some are used
The fixed form that double faced adhesive tape (or other glue classes) is pasted, bass horn usually come off because insecure, have impact on the life-span of product,
Simultaneously to the resonance problem of loudspeaker and structural member also without any improvement.
There is a kind of rubber sleeve in the prior art, the vibration of loudspeaker can be alleviated to a certain extent.But following lack be present
Fall into：
First, loudspeaker need out the mounting hole of rubber sleeve, and frame needs to be made big, can not reduce the size of product；
2nd, loudspeaker and fixture connected mode belong to clamping, the problem of being limited by rubber sleeve thickness, and vibration still can be to
Outer transmission, each structural member of sound equipment is produced resonance, influence tonequality；
3rd, loudspeaker bottom does not have precautions against earthquakes, when loudspeaker vibrate downwards, the deflection very little of rubber sleeve, loudspeaker easily with
Fixture hits, by vibration outwards transmission；
4th, effect of the rubber sleeve without sealing in the design, it is still necessary to the extra design for carrying out encapsulation scheme.
Therefore, there is an urgent need to a kind of stereo set, loudspeaker and resonance caused by each structural member is eliminated, improve stereo set
Tonequality.
Utility model content
The defects of existing for prior art, technical problem to be solved in the utility model are to provide a kind of sound equipment and set
Standby, it can effectively solve the problems, such as that loudspeaker resonate with structural member, improve the tonequality of stereo set.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of stereo set, including housing and the loudspeaker in the housing, the loudspeaker are consolidated by loudspeaker vibrationproof
Determine structure in the housing, the loudspeaker vibrationproof fixed structure includes gum cover and rubber cushion, be provided with the gum cover and
The loudspeaker installation cavity being adapted at the top of the loudspeaker, the rubber cushion are adapted with the bottom of the loudspeaker, the top of the loudspeaker
Portion is arranged in the loudspeaker installation cavity, and the bottom of the loudspeaker is against on the rubber cushion.
As an improvement the loudspeaker mounting groove being adapted with the bottom of the loudspeaker is provided with the rubber cushion, it is described
The bottom of loudspeaker is arranged in the loudspeaker mounting groove.
As an improvement the housing includes the upper shell and lower house being installed together, the loudspeaker are arranged on institute
State in the accommodating cavity that upper shell and the lower house are formed.
As an improvement the upper shell is provided with the gum cover mounting groove being adapted with the gum cover, the gum cover peace
In the gum cover mounting groove.
As an improvement it is provided with circumferential annular positioning groove, institute in the gum cover one side relative with the rubber cushion
State and the opening position of the annular positioning groove is corresponded on lower house be provided with the circular orientation bar being adapted with the annular positioning groove,
After the gum cover installs, the circular orientation bar is located in the annular positioning groove.
As an improvement the opening position that the lower house corresponds to the rubber cushion is provided with the glue being adapted with the rubber cushion
Mounting groove is padded, the rubber cushion is arranged in the rubber cushion mounting groove.
As an improvement the ante-chamber of the upper shell, which is let out, is provided with Air Filter in acoustic aperture, the Air Filter is arranged on institute
State on the inside of upper shell.
As an improvement the loudspeaker are bass horn, the lower house is provided with back cavity and lets out acoustic aperture.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
Because stereo set provided by the utility model, including housing and the loudspeaker in housing, loudspeaker pass through loudspeaker
Vibrationproof fixed structure is arranged in housing, and loudspeaker vibrationproof fixed structure includes gum cover and rubber cushion, is provided with gum cover and loudspeaker
The loudspeaker installation cavity that is adapted of top, rubber cushion is adapted with the bottom of loudspeaker, and the top of loudspeaker is arranged in loudspeaker installation cavity,
The bottom of the loudspeaker is against on the rubber cushion of housing bottom.This stereo set is consolidated loudspeaker by using loudspeaker vibrationproof fixed structure
It is scheduled in housing, the loudspeaker vibrationproof fixed structure is provided with gum cover and rubber cushion, and gum cover is arranged on the upper end of loudspeaker, by loudspeaker and shell
The structural member isolation on body top；Rubber cushion is arranged on the lower end of loudspeaker, and loudspeaker are isolated with the structural member of lower housing portion；When loudspeaker are sent out
During raw vibration, elastic deformation occurs for gum cover and rubber cushion, can be by the absorption of vibrations, and therefore, vibration is not transmitted on housing,
Would not occur impulsive force between stereo set and ground or support member, using such structure, eliminate loudspeaker on housing
The process for beating screw hole, reduces cost, also reduces the volume of loudspeaker, effectively solves what loudspeaker resonated with housing
Problem, the tonequality of stereo set is improved, at the same time it can also be ensured that the sealing effectiveness that loudspeaker ante-chamber is good.
