Abstract
A receiver comprises a front cover, a vibrating plate, a voice coil, a spring washer, a magnet, a support and a PC board which are connected successively. The vibrating plate is provided with reinforcing ribs distributed in an annular manner; the inner side of the support is provided with a step; the step is located at the joint between the support and the vibrating plate; and the top of each reinforcing rib is provided with a groove. The tops of the reinforcing ribs on the vibrating plate are provided with the grooves, so that the reinforcing rib is firmer in structure, the deformation degree of the vibrating plate is reduced and the rigidity of the vibrating plate is further increased; the inner side of the support is provided with the step, so that the connection between the support and the vibrating plate is more stable; while the beneficial effect of a copper ring in the prior art is maintained, the copper ring is removed, so that the structure of the receiver is further simplified and the material cost and the machining cost are reduced.
Description
Technical field
The utility model relates to a kind of receiver.
Background technology
Receiver, is also referred to as receiver, is a kind of accessory that the communication tools such as phone, intercom, mobile phone transmit sound, is the one of loud speaker, the normal part that all transmits sound for describing electronic product.
General receiver comprises protecgulum, oscillating plate, voice coil loudspeaker voice coil, spring shim, magnet, support and PC plate, simultaneously because the rigidity of oscillating plate is lower, so the reinforcement that generally can be provided with annular spread on oscillating plate is to strengthen its rigidity.In order to improve the tonequality of receiver, generally can on oscillating plate, increase copper ring, specifically, copper ring plays two effects: the first, further increase the rigidity of oscillating plate; The second, make support and oscillating plate combination closely with firm.
But, add copper ring, but cause the structure of receiver more complicated, increase material cost and processing cost.
Utility model content
Based on this, be necessary the problem for prior art, a kind of receiver simple in structure is provided.
A kind of receiver, comprise the protecgulum, oscillating plate, voice coil loudspeaker voice coil, spring shim, magnet, support and the PC plate that connect successively, oscillating plate is provided with the reinforcement of annular spread, and the inner side of support is provided with step, step is positioned at the junction of support and oscillating plate, and the top of reinforcement is provided with groove.
Above-mentioned receiver, arranges groove by the top of the reinforcement on oscillating plate, makes the structure of reinforcement more firm, has reduced the degree of oscillating plate distortion, further increases the rigidity of oscillating plate; By the inner side at support, step is set, makes support and oscillating plate stable connection.Retaining under the prerequisite of the beneficial effect of copper ring in prior art, cast out copper ring, further simplify the structure of receiver, reduce material cost and processing cost.

Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
With reference to figures 1 through 5, a kind of receiver, comprise the protecgulum 100, oscillating plate 200, voice coil loudspeaker voice coil 300, spring shim (the Spring Washer that connect successively, be commonly called as washer) 400, magnet 500, support 600 and PC plate 700, oscillating plate 200 is provided with the reinforcement 210 of annular spread, the inner side of support 600 is provided with step 610, and step 610 is positioned at the junction of support 600 and oscillating plate 200, and the top of reinforcement 210 is provided with groove 211.
In the present embodiment, the cross section of groove 211 is isosceles trapezoid.Cross section is the groove 211 of isosceles trapezoid, and its stabilized structure is conducive to increase the steadiness of reinforcement 210, thereby increases the rigidity of oscillating plate 200.In other embodiments, the cross section of groove 211 can be also isosceles triangle or arc.
In the present embodiment, the surrounding that protecgulum 100 center is provided with the first through hole 110, the first through holes 110 is provided with the second through hole 120.The first through hole 110 and the second through hole 120 are set to be conducive to user and to connect better the sound that receiver sends.
In the present embodiment, the radius of the first through hole 110 is less than the radius of the second through hole 120.The second through hole 120 that radius is larger is distributed in the periphery of protecgulum 100, and the second through hole 120 that radius is less is distributed in protecgulum 100 center, makes the tonequality of receiver better.
In the present embodiment, the cross section of step 610 becomes stairstepping.
In sum, receiver of the present utility model arranges groove 211 by the top of the reinforcement 210 on oscillating plate 200, makes the structure of reinforcement 210 more firm, has reduced the degree that oscillating plate 200 is out of shape, and further increases the rigidity of oscillating plate 200; By step 610 being set in the inner side of support 600, make support 600 and oscillating plate 200 stable connections.Retaining under the prerequisite of the beneficial effect of copper ring in prior art, cast out copper ring, further simplify the structure of receiver, reduce material cost and processing cost.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
