Abstract

The utility model relates to the sound production instrument about electroacoustic conduction. On the basis of the existing bone conduction device, a vibrating sheet and a mounting seat are designed into the integral component of a machine core holder in plastic. A machine core is arranged in the mounting seat. The vibrating sheet is fixedly connected with an outer shell through a fixed piece and a fastening piece. The bone conduction device formed in this way, has good electroacoustic performance and high sensitivity, and the sound can be conducted in a bone conduction way or in an air conduction simulation way. The utility model has the advantages of simple structure, easy fabrication, low cost and small volume.

Description

Osseosonometer

This utility model relates to a kind of sound equipment of electroacoustic conduction.

Osseosonometer is the apparatus by the skeleton conduction sound, it produces alternating magnetic field with low frequency signal by coil in magnetic circuit, make oscillator produce vibration, body and oscillator owing to it links together again, when signal frequency was in audio range, then Zhen Dong body just can send the sound, and its effect is identical with earphone.According to above-mentioned operation principle, present Osseosonometer is mainly by stator, shell, vibrating reed, margin, skeleton frame, magnet steel, coil, conducting magnetic column, skeleton, securing member and some other adnexa are formed, magnet steel, coil, skeleton, conducting magnetic column are installed in the copper skeleton frame of foreign side's inner ring around the movement that circle, suit constitute according to certain relation, copper vibrating reed is with screw, be fastened on the skeleton frame by the margin command range, and vibrating reed is clamped from the two sides by the irony stator again and is fixed together with screw and shell.The deficiencies in the prior art part is: 1, complex structure, member are many, corresponding technological requirement height, make difficulty, as vibrating reed palpus cold-punching mould stamped, circular hole and magnet steel are tight fit in the rigid member skeleton frame, also have other fastening relation, must be through car, mill, working procedures processing such as mill, boring, hitch, the required precision height; 2, parts such as skeleton frame, vibrating reed adopt copper material manufacturing, cost height.

The purpose of this utility model is to avoid weak point of the prior art, and a kind of performance requirement, simple in structure that satisfies is provided, easily the Osseosonometer product of making.

Realize the purpose of the technical program by following measure.On the basis of existing Osseosonometer, vibrating reed is become the core frame integrated member with mount pad two parts with plastic design, the movement that magnet steel, coil, conducting magnetic column, skeleton are formed around circle, suit according to certain relation is installed in the mount pad of core frame, and the vibrating reed of core frame is fixedlyed connected with shell by stator, securing member.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 2, core frame front view

Fig. 3, core frame cutaway view

Among the figure: (1) dome; (2) screw; (3) nut; (4) stator; (5) pad; (6) shell; (7) core frame; (8) magnet steel; (9) coil; (10) conducting magnetic column; (11) skeleton; (12) lid; (13) spring; (14) lug plate; (15) vibrating reed; (16) mount pad.

This Osseosonometer removes original stator (4), pad (5), shell (6), magnet steel (8), coil (9), conducting magnetic column (10), skeleton (11) main member, outside dome (1), lid (12), spring (13), lug plate (14) accessory and the securing member, it also has core frame (7) member.Core frame is by vibrating reed (15) and mount pad (16) two parts integrated member with injection molding.The outline of vibrating reed can be nonocclusive square, circular or other shape, and entity structure is not generally adopted for improving vibrating effect in its middle part, and empty the become various cantilevers that are beneficial to vibration, circuitous and so on shape are hugged in its some position.That the outline of mount pad also can be is square, circular or other shape, but considers and be convenient to make, and its outline is consistent with the vibrating reed part well, and its middle part is the hole that matches with magnet steel.In the accompanying drawing institute example, core frame is the integrated member of being located to be connected with mount pad, making with plastics with the both ends of S shape by the vibrating reed (15) of circle S shape and mount pad cylindraceous (16) two parts, vibrating reed, one-shot forming, a lot of machining processes and mutual quality of fit requirement can be removed from, also the assembling link can be reduced in addition.Circle is made at the middle part of S shape vibrating reed, and has two erection openings, is connected and fixed for screw.Magnet steel, coil, conducting magnetic column, skeleton are installed in the mount pad of core frame around the movement that circle, suit constitute according to certain relation, the vibrating reed of core frame is fixedlyed connected with shell by stator, securing member, form the Osseosonometer main body, equipped again go up dome (1), lid (12), spring (13), lug plate parts such as (14) Osseosonometer integral body.

The relative prior art of the utility model has following advantage:

1, good, the flexibility ratio raising of electroacoustic performance, in its place in circuit, for example recorder, radio, audiphone, when doing load with it, result of use is better, little, the clear sound of noise, its hearing aid effect is better during especially as the load of bone conduction type audiphone, and it can conduct sound in the mode of bone conduction and can simulate again the mode of conductance and conduct sound.

2, simple structure, easily manufacturing make the more small and exquisite and cost reduction of Osseosonometer.
