Abstract
The invention discloses a high sound pressure output telephone receiver; the high sound pressure output telephone receiver comprises an upper telephone receiver housing, and a vibration film; the vibration film is placed inside the upper telephone receiver housing in order to form a cavity of telephone receiver sound pressure output; the upper telephone receiver housing is provided with a sound outlet port; the sound outlet port is arranged at the front end of the upper telephone receiver housing, and the sound outlet port is a rectangular structure; the front end of the vibration film is a protruded arc-shaped structure, and extends outside the sound outlet port. By such a way, the provided high sound pressure output telephone receiver can correspondingly increase the area of the vibrating reed by stretching the vibration film out from the sound outlet port of the upper telephone receiver housing, thus enlarging the area of the whole vibration film in the premise of immobilizing the dimension of the telephone receiver housing; in condition of the same vibration amplitude, the vibration area is larger, the sound pressure output is higher, thereby increasing the overall sound pressure output of the telephone receiver; therefore, the telephone receiver has a better performance.
Description
Technical field
The present invention relates to the field of receiver, particularly relate to the receiver that a kind of high sound pressure exports.
Background technology
Usually said receiver refers to moving coil receiver, its operation principle (physical principle) is similar with traditional coil-moving speaker: the audio electrical signal feed-in voice coil loudspeaker voice coil of change, voice coil loudspeaker voice coil is placed in the magnetic gap of a magnetic circuit, the driving of the electromagnetic force (Lorentz force) of change that voice coil loudspeaker voice coil produces because of the electric current of change and up-down vibration, and drive vibrating membrane to drive front and back air, produce sound wave.Because what need to export is a kind of electroacoustic property of pressure field, normally, in the structure of receiver, also the front and back operatic tunes and acoustic damping can be configured, for adjusting acoustic characteristic.
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 generally meeting be provided with the reinforcement of annular spread to strengthen its rigidity on oscillating plate.In order to improve the tonequality of receiver, generally can increase copper ring on oscillating plate, specifically, copper ring plays two effects: the first, increases the rigidity of oscillating plate further; The second, support and oscillating plate are combined closely with firm.
But, with the addition of copper ring, but cause the structure of receiver more complicated, add material cost and processing cost.
Summary of the invention
The technical problem that the present invention mainly solves is to provide the receiver that a kind of high sound pressure exports, by the sound outlet of vibrating membrane at receiver upper casing is stretched out, the area of vibrating reed can be increased accordingly, make the area expanding whole vibrating membrane when receiver shell size is fixed, when identical Oscillation Amplitude, vibration area is larger, and its acoustic pressure exports higher, thus the overall acoustic pressure improving receiver exports, and has better performance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide the receiver that a kind of high sound pressure exports, comprise receiver upper casing and vibrating membrane, described vibrating membrane is placed in receiver upper casing the cavity forming receiver acoustic pressure and export, described receiver upper casing is provided with sound outlet, 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 extends to sound outlet outside.
In a preferred embodiment of the present invention, described vibrating membrane comprises bracing ring, vibrating reed and film, described bracing ring is arranged on the inwall of receiver upper casing, and described vibrating reed is arranged in bracing ring, and described film is arranged between vibrating reed and bracing ring.
In a preferred embodiment of the present invention, described film molds fluted body structure or is planar structure between vibrating reed and bracing ring.
In a preferred embodiment of the present invention, described vibrating membrane is located by fixture or on receiver upper casing, is arranged bayonet socket and is fixed in receiver upper casing.
The invention has the beneficial effects as follows: the receiver that high sound pressure of the present invention exports, by the sound outlet of vibrating membrane at receiver upper casing is stretched out, the area of vibrating reed can be increased accordingly, make the area expanding whole vibrating membrane when receiver shell size is fixed, when identical Oscillation Amplitude, vibration area is larger, and its acoustic pressure exports higher, thus the overall acoustic pressure improving receiver exports, and has better performance.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
