Abstract
The utility model discloses a bone conduction loudspeaker, which comprises a casing assembly, a vibrating diaphragm assembly and an upper cover. The casing assembly comprises a casing upper edge step, a magnet yoke, a magnet and a magnetically-conducting plate. The magnet is arranged inside the magnet yoke, and the magnetically-conducting plate is arranged above the magnet; the vibrating diaphragm assembly comprises a leaf spring, a vibrating diaphragm and a coil, wherein the vibrating diaphragm is connected with the ring structure of the leaf spring, and the coil is fixed at the intersection site of the two curved surfaces of the vibrating diaphragm and placed inside the magnet yoke; the upper cover is arranged above the vibrating membrane assembly and is fixedly mounted inside the casing upper edge step; the casing assembly also comprises an elastic structure for connecting the casing upper edge step and the magnet yoke together; symmetric strip-shaped holes are arranged inside the casing upper edge step; the vibrating diaphragm is fixed on the inner sides of the symmetric strip-shaped holes on the casing upper edge step; and a protrusion structure with a symmetric structure is arranged at the edge of the leaf spring. The bone conduction loudspeaker remains the characteristic of high tone quality of the traditional loudspeaker, and eliminates the shortcoming that the traditional loudspeaker damages the hearing ability of a user easily.
Description
[technical field]
The utility model relates to a kind of loud speaker, in particular, relates to a kind of miniature loudspeaker with osteoacusis effect.
[background technology]
At present, a small-sized loud speaker all is equipped with in existing earphone inside.The built-in vibrating diaphragm of this loud speaker comes sounding by vibrate air under the effect of coil, in order to obtain acoustics preferably, the employed vibrating diaphragm of existing ear earphone generally includes the curved surface of two different curvature radius, the positive camber that its radius of curvature is bigger is used for sounding low, Mid Frequency, the curved surface that radius of curvature is little then is used for the sounding of high band.In addition; also can adopt the method for ear canal to reach the air invention sympathetic response that makes in the ear chamber usually; obtaining auditory effect preferably, but existing earphone can cause damage to user's hearing, and especially the damage that caused when big volume work of earphone is more obvious.
For this reason; people have proposed to adopt bone-conduction speaker to substitute the technical scheme of ventional loudspeakers; to reach the purpose of protection user hearing; conventional earphone also has certain osteoacusis effect when big volume is worked; and also can make its ambient air produce vibration usually when using bone-conduction speaker; its difference is: conventional or earphone is based on vibrate air; bone-conduction speaker is then to produce the mechanical oscillation of solid; when big volume is worked; all can make the user feel uncomfortable, especially conventional loud speaker will cause damage to user's hearing when long-time big volume is worked.
[utility model content]
The purpose of this utility model is to provide a kind of bone-conduction speaker at above-mentioned technological deficiency, and this a kind of bone-conduction speaker is even if not only have low-power consumption, broadband, high sensitivity and also can not damage user's hearing when big volume is worked.
The technical solution of the utility model is as described below: a kind of bone-conduction speaker, comprise the shell assembly, vibrating diaphragm assembly and lid, the shell assembly comprises shell upper edge step, yoke, magnet and magnetic conductive board, magnet is set in the yoke, the magnet top is provided with magnetic conductive board, the vibrating diaphragm assembly comprises shell fragment, vibrating diaphragm and coil, vibrating diaphragm is connected with the circulus of shell fragment, coil stationary is in two curved surface intersections of vibrating diaphragm, be positioned in the yoke, loam cake is arranged at vibrating diaphragm assembly top, all be fixedly mounted in the step of shell upper edge, its feature also is: the shell assembly also comprises an elastic construction that shell upper edge step and yoke are linked into an integrated entity, be provided with the bar hole of symmetry in the step of described shell upper edge, described vibrating diaphragm is fixed in symmetrical bar hole inboard on the step of shell upper edge, and described shell fragment edge is provided with the outstanding structure of symmetrical structure.
According to the utility model of said structure, its feature is that also described elastic construction and shell upper edge step and yoke are an integral body.
The utility model according to said structure, its beneficial effect is: the utility model can keep conventional loudspeakers good sound quality effect when work, the characteristics that possessed simultaneously osteoacusis again, realized the perfect adaptation between the two, can realize the power of being imported is shunted and user's duct is reduced pressure, to reach the defective that keeps the beautiful characteristics of conventional loudspeakers tone color, eliminates its easy damaged user hearing.

[embodiment]
Below in conjunction with accompanying drawing and execution mode the utility model is further described:
As shown in Figure 1, a kind of bone-conduction speaker, comprise the shell assembly, vibrating diaphragm assembly and loam cake 3, loam cake 3 is positioned at vibrating diaphragm assembly top, all be fixedly installed in step 4 places, shell upper edge on shell assembly top, the shell assembly comprises shell upper edge step 4, yoke 7, magnet 8 and magnetic conductive board 9, fixedly mount magnet 8 and dress magnetic conductive board 9 in the yoke 7 from inside to outside successively, the vibrating diaphragm assembly comprises shell fragment 1, vibrating diaphragm 2 and coil 6, coil 6 is fixed on two curved surface intersections of vibrating diaphragm 2, be positioned in the gap of yoke 7 and magnet 8 and magnetic conductive board 9, vibrating diaphragm 2 is fixedlyed connected with the circulus 11 of shell fragment 1, the shell assembly also comprises an elastic construction 5, and elastic construction 5 connects shell upper edge step 4 and yoke 7.
Shown in accompanying drawing 2, accompanying drawing 3, the structure that elastic construction 5 on the shell assembly has adopted integral forming technique to make, three are and are symmetrically distributed and two ends are the fixedly connected shell of the linear structure upper edge step 4 and the yoke 7 of 90 ° of bendings, shell fragment 1 edge has the outstanding structure 11 of symmetry, the edge is a circulus 11, and outstanding structure 11 connects into an integral body with circulus 12.
As shown in Figure 4, audio frequency apparatuses such as the two ends of coil 6 and MP3 are linked to each other just can use, after the energized, test acoustic pressure and current relationship curve be the size and the acoustic pressure relation no longer in direct ratio of electric current at this moment.
