Abstract

The invention discloses a kind of receiver of high sound pressure output, including receiver upper casing and vibrating membrane, described vibrating membrane is placed on the cavity that the output of receiver acoustic pressure is formed in receiver upper casing, sound outlet is provided with described receiver upper casing, the front end that described sound outlet is arranged on receiver upper casing is rectangle structure, and the front end of described vibrating membrane is the arc-shaped structure of protrusion and extended to outside sound outlet.Through the above way, the receiver of high sound pressure output provided by the invention, by the way that sound outlet of the vibrating membrane in receiver upper casing is stretched out, the area of vibrating reed can be increased accordingly, make the area that whole vibrating membrane is expanded in the case where receiver shell size is fixed, in the case of identical Oscillation Amplitude, it is bigger to vibrate area, the output of its acoustic pressure is higher, so as to improve the output of the overall acoustic pressure of receiver, has better performance.

Description

A kind of receiver of high sound pressure output
Technical field
The present invention relates to the field of receiver, more particularly to a kind of receiver of high sound pressure output.
Background technology
Usually said receiver refers to moving coil receiver, its operation principle(Physical principle)Raised with traditional moving-coil type Sound device is similar:The audio electrical signal feed-in voice coil loudspeaker voice coil of change, voice coil loudspeaker voice coil are placed in the magnetic gap of a magnetic circuit, and voice coil loudspeaker voice coil is because of change Electric current caused by change electromagnetic force(Lorentz force)Driving and up-down vibration, and drive vibrating membrane empty before and after driving Gas, produce sound wave.Since it is desired that output is a kind of electroacoustic property of pressure field, normally, can also match somebody with somebody in the structure of receiver The front and rear operatic tunes and acoustic damping are put, for adjusting acoustic characteristic.
In general receiver includes protecgulum, oscillating plate, voice coil loudspeaker voice coil, spring shim, magnet, support and PC plates, simultaneously because The rigidity of oscillating plate than relatively low, so typically can on oscillating plate the reinforcement provided with annular spread to strengthen its rigidity.In order to The tonequality of receiver is improved, can typically increase copper ring on oscillating plate, specifically, copper ring plays two effects:First, enter One step increases the rigidity of oscillating plate;Second, support is combined with oscillating plate close and firm.
However, with the addition of copper ring, but cause the structure of receiver more complicated, add material cost and processing cost.
The content of the invention
The present invention solves the technical problem of the receiver for providing a kind of output of high sound pressure, by by vibrating membrane by The sound outlet for talking about device upper casing stretches out, and can increase the area of vibrating reed accordingly, makes the feelings fixed in receiver shell size The area of whole vibrating membrane is expanded under condition, in the case of identical Oscillation Amplitude, vibration area is bigger, and the output of its acoustic pressure is got over Height, so as to improve the output of the overall acoustic pressure of receiver, there is better performance.
In order to solve the above technical problems, one aspect of the present invention is:Provide a kind of high sound pressure output Receiver, including receiver upper casing and vibrating membrane, it is defeated that described vibrating membrane is placed on formation receiver acoustic pressure in receiver upper casing The cavity gone out, sound outlet is provided with described receiver upper casing, before described sound outlet is arranged on receiver upper casing End is rectangle structure, and the front end of described vibrating membrane is the arc-shaped structure of protrusion and extended to outside sound outlet.
In a preferred embodiment of the present invention, described vibrating membrane includes bracing ring, vibrating reed and film, described branch Support ring is arranged on the inwall of receiver upper casing, and described vibrating reed is arranged in bracing ring, and described film is arranged on vibration Between piece and bracing ring.
In a preferred embodiment of the present invention, described film molds fluted body knot between vibrating reed and bracing ring Structure is planar structure.
In a preferred embodiment of the present invention, described vibrating membrane is positioned by fixture or set on receiver upper casing Bayonet socket is put to be fixed in receiver upper casing.
The beneficial effects of the invention are as follows:The present invention high sound pressure output receiver, by by vibrating membrane on receiver The sound outlet of shell stretches out, and can increase the area of vibrating reed accordingly, makes to expand in the case where receiver shell size is fixed The big area of whole vibrating membrane, in the case of identical Oscillation Amplitude, vibration area is bigger, and the output of its acoustic pressure is higher, so as to The overall acoustic pressure output of receiver is improved, there is better performance.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for For those of ordinary skill in the art, on the premise of not paying creative work, it can also be obtained according to these accompanying drawings other Accompanying drawing, wherein:
Fig. 1 is the structural representation of a preferred embodiment of the receiver of high sound pressure output of the present invention;
Fig. 2 is Fig. 1 top view;
Reference is as follows:1st, receiver upper casing, 2, vibrating membrane, 11, sound outlet, 12, bayonet socket, 21, bracing ring, 22, Vibrating reed, 23 films.
Embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example is only the part of the embodiment of the present invention, rather than whole embodiments.It is common based on the embodiment in the present invention, this area All other embodiment that technical staff is obtained under the premise of creative work is not made, belong to the model that the present invention protects Enclose.
As depicted in figs. 1 and 2, the embodiment of the present invention includes:
A kind of receiver of high sound pressure output, including receiver upper casing 1 and vibrating membrane 2, described vibrating membrane 2 be placed on by The cavity that the output of receiver acoustic pressure is formed in device upper casing 1 is talked about, sound outlet 11 is provided with described receiver upper casing 1, it is described Sound outlet 11 be arranged on the front end of receiver upper casing 1 and be rectangle structure, the front end of described vibrating membrane 2 for protrusion circle Arcuate structure is simultaneously extended to outside sound outlet 11.The vibration area of acoustic pressure output is more effectively expanded, improves receiver Acoustic pressure output, it is sent higher sound in the case where receiver overall volume size is certain, improve called The performance of device, there is more preferable applied technical field.
In above-mentioned, described vibrating membrane 2 includes bracing ring 21, vibrating reed 22 and film 23, and described bracing ring 21 is installed On the inwall of receiver upper casing 1, described vibrating reed 22 is arranged in bracing ring 21.Wherein, described film 23 is vibrating Fluted body structure is molded between piece 22 and bracing ring 21 or it is planar structure, described film 23 is arranged on the He of vibrating reed 22 Between bracing ring 21.
Wherein, described bracing ring 21 and vibrating reed 22, bracing ring 21 and film 23 are respectively hot-forming bonding, or Bracing ring 21 and the integrated punching of vibrating reed 22 shaping, then with the hot-forming cohesive side of film 23.
