Description
Technical field
The present invention relates to electro-acoustic product technical field, in particular to a kind of vibrating diaphragm and the minitype acoustic generator equipped with the vibrating diaphragm.
Background technique
Minitype acoustic generator is a kind of important acoustic element in portable electronic device, for sound wave electric signal to be converted into
Voice signal outflow, is a kind of energy conversion device.Minitype acoustic generator generally includes vibrational system and magnetic circuit system, vibrational system
Including combined vibrating diaphragm and voice coil, vibrating diaphragm includes the top dome portion, ring portion and edge part successively combined from inside to outside, vibration
Film is the important component of minitype acoustic generator, has vital effect to the sound reproduction performance of minitype acoustic generator, it determines micro-
Type acoustical generator is by electric energy to the conversion quality of sound energy.
The ring portion of existing vibrating diaphragm is usually no decorative pattern, or a kind of only recessed decorative pattern, i.e., the protrusion direction of decorative pattern with
The protrusion direction in ring portion on the contrary, such structure vibrating diaphragm in vibration Impact direction it is identical, vibrating diaphragm easily generates folding line or collapses
Fall into equal deformation, vibrating diaphragm caused to polarize, audio distortions are serious, can not true restoring acoustical signal, sound quality is poor, it is difficult to meet
Requirement of the people to the loud sound quality of electronic equipment.
Summary of the invention
For disadvantages described above, first technical problem to be solved by this invention is to provide a kind of vibrating diaphragm, this vibrating diaphragm is not easy
Deformation, can effectively reduce distortion, improve the sound quality of minitype acoustic generator.
Based on the same inventive concept, second technical problem to be solved by this invention is to provide a kind of miniature sounding
Device, the distortion of this minitype acoustic generator is small, and sound quality is high, can satisfy requirement of the people to the loud sound quality of electronic equipment.
In order to solve the first technical problem mentioned above, the technical scheme is that
A kind of vibrating diaphragm, including sequentially connected top dome portion, ring portion and edge part from inside to outside are distributed in the ring portion
There is decorative pattern, the decorative pattern includes convex decorative pattern identical with the protrusion direction in the ring portion, while further including and the ring portion
The opposite recessed decorative pattern of protrusion direction.
Wherein, the vertical cross section shape of the decorative pattern is U-shaped, V-arrangement or one of arc-shaped or a variety of.
Wherein, the flat shape of the decorative pattern is ellipse, olive shape or track type, the long axis extension side of each decorative pattern
To consistent with the width direction in the ring portion.
Wherein, the vibrating diaphragm is rectangular configuration, and the decorative pattern is distributed in the four corners in the ring portion, and is located at each
The decorative pattern of a corner positions includes the convex decorative pattern and the recessed decorative pattern.
As an implementation, decorative pattern described in a row, the convex flower are distributed in the width direction in the ring portion
Line is alternatively arranged with the recessed decorative pattern.
As another embodiment, two rows of decorative patterns are distributed in the width direction in the ring portion.
Wherein, the row in two rows of decorative patterns is the convex decorative pattern, and another row is the recessed decorative pattern, and two rows of flowers
The arrangement of line interleaved.
As another embodiment, decorative pattern described in three rows is distributed in the width direction in the ring portion.
Wherein, the two rows decorative pattern positioned at two sides is the recessed decorative pattern or the convex decorative pattern, is located in the middle a row
The decorative pattern be the convex decorative pattern or the recessed decorative pattern, and be located in the middle decorative pattern described in a row simultaneously be located at two sides two rows
The decorative pattern interleaved arrangement.
To solve above-mentioned second technical problem, the technical scheme is that
A kind of minitype acoustic generator, including vibrational system and magnetic circuit system, the vibrational system include combined vibration
Film and voice coil, the vibrating diaphragm are above-mentioned vibrating diaphragm.
After above-mentioned technical proposal, the beneficial effects of the present invention are:
Since the ring part of vibrating diaphragm of the present invention is furnished with convex decorative pattern identical with the protrusion direction in ring portion, be also distributed with
The opposite recessed decorative pattern of the protrusion direction in ring portion.The protrusion direction of decorative pattern is different, so that the Impact direction of vibrating diaphragm is different, two kinds convex
Play contrary decorative pattern to cooperate, enable vibrating diaphragm subject to various forces in vibration, effectively improve vibrating diaphragm because
Folding line is generated by unidirectional power or is collapsed bad, it is therefore prevented that vibrating diaphragm polarization effectively reduces distortion, maximum limit
Degree reduces voice signal, improves the sound quality of minitype acoustic generator, gets over so as to meet people to electronic equipment
Carry out the requirement of higher sound quality.
Since the vibrating diaphragm of minitype acoustic generator of the present invention is above-mentioned vibrating diaphragm, to effectively reduce distortion, sound quality is high,
It can satisfy requirement of the people to the loud sound quality of electronic equipment.
In conclusion vibrating diaphragm of the present invention and the minitype acoustic generator equipped with the vibrating diaphragm solve minitype acoustic generator in the prior art
It is distorted serious technical problem, vibrating diaphragm of the present invention and the minitype acoustic generator equipped with the vibrating diaphragm are distorted small, sound quality height, Neng Gouman
Requirement of the sufficient people to the loud sound quality of electronic equipment.
