Abstract
The utility model relates to an osteoacusis speaker of miniature separable leakage prevention sound. An osteoacusis speaker of miniature separable leakage prevention sound, includes subassembly and lower subassembly, wherein, last subassembly include the roof and inlay the vibrations piece in roof bottom, the bottom at vibrations piece both ends is provided with the damping connecting block, the subassembly includes the bottom plate down, the bottom of bottom plate is inlayed and is fixed with the circuit board, the intermediate position cover of bottom plate top surface is equipped with the coil, the top surface of bottom plate still is provided with the magnet steel, the bottom and the bottom plate of damping connecting block are connected, the lateral surface of magnet steel is hugged closely to the medial surface of damping connecting block. The utility model discloses an osteoacusis speaker of miniature separable leakage prevention sound, it is small, be convenient for use in the miniaturation product, can be divided into two parts installation, conveniently coordinate the mechanical mechanism of multiple pattern, the installation is convenient, adopt the damping connecting block will shake piece and bottom plate flexible coupling, reduced because of the hard hourglass sound that leads to of connecting.
Description
Technical field
The utility model relates to bone-conduction speaker field, particularly relates to a kind of miniature separable bone-conduction speaker without leaking sound.
Background technology
Bone-conduction speaker is in the market all Integral design, is not easy to mechanical mechanism and coordinates, and installs fixing existing problems; The intraware of bone-conduction speaker is all Hard link, and the energy transferring in bone conduction vibrations face, to other assemblies, causes other assemblies to shake air and causes leakage sound; Size is comparatively large, is not easy to design microminiaturized product.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of miniature separable bone-conduction speaker without leaking sound easy for installation.
The utility model solves the technical scheme that its technical problem adopts: a kind of miniature separable bone-conduction speaker without leaking sound, and it comprises assembly and lower assembly; Wherein, described upper assembly comprises top board and is embedded in the seismic mass bottom top board; The bottom at described seismic mass two ends is provided with damping contiguous block; Described lower assembly comprises base plate; The bottom of described base plate is inlayed and is fixed with circuit board; The centre position of described plate top surface is arranged with coil; The end face of described base plate is also provided with magnet steel; The bottom of described damping contiguous block is connected with base plate; The medial surface of described damping contiguous block is close to the lateral surface of magnet steel.
The centre of described plate top surface is provided with boss, and described coil is set on boss.
Described circuit board is electrically connected with coil.
The beneficial effects of the utility model: a kind of miniature separable bone-conduction speaker without leaking sound of the present utility model, volume is little, is convenient to be applied in microminiaturized product; Two parts can be divided into install, the convenient mechanical mechanism coordinating multiple pattern, it is convenient to install; Adopt damping contiguous block seismic mass and base plate to be flexible coupling, decrease the leakage sound because Hard link causes.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view of a kind of miniature separable bone-conduction speaker without leakage sound of embodiment;
Fig. 2 is the schematic diagram of a kind of miniature separable internal structure without leakage sound of embodiment;
Fig. 3 is a kind of miniature separable without leaking the upper assembly of sound and the schematic diagram of lower assembly separated position of embodiment.
Embodiment
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection range of the present utility model and limiting.
Embodiment
As shown in Figure 1 to Figure 3, a kind of miniature separable bone-conduction speaker without leaking sound, it comprises assembly 1 and lower assembly 2; Wherein, the seismic mass 12 that described upper assembly 1 comprises top board 11 and is embedded in bottom top board 11; The bottom at described seismic mass 12 two ends is provided with damping contiguous block 13; Described lower assembly 2 comprises base plate 21; The bottom of described base plate 21 is inlayed and is fixed with circuit board 22; The centre position of described base plate 21 end face is arranged with coil 23; The end face of described base plate 21 is also provided with magnet steel 24; The bottom of described damping contiguous block 13 is connected with base plate 21; The medial surface of described damping contiguous block 13 is close to the lateral surface of magnet steel 24; The centre of described base plate 21 end face is provided with boss, and described coil 23 is set on boss; Described circuit board 22 is electrically connected with coil 23.
After upper assembly and lower assembly are assembled by the present embodiment respectively, more corresponding mechanical mechanism is coordinated to install, very convenient; By circuit board 22 control coil 23, coil 23 produces magnetic field, forms the vibrations corresponding with sound wave.
A kind of miniature separable bone-conduction speaker without leaking sound of the present embodiment, volume is little, is convenient to be applied in microminiaturized product; Two parts can be divided into install, the convenient mechanical mechanism coordinating multiple pattern, it is convenient to install; Adopt damping contiguous block seismic mass and base plate to be flexible coupling, decrease the leakage sound because Hard link causes.
Above-described embodiment should not limit the utility model by any way, and the technical scheme that the mode that all employings are equal to replacement or equivalency transform obtains all drops in protection range of the present utility model.
