It moves.
In some loudspeakers, especially in Microspeaker, in order to guarantee that skew does not occur for voice coil 300, vibrating diaphragm is prevented
100 polarize, and need to be arranged a centring disk 200, and the outer fixing portion 220 of centring disk 200 is connect simultaneously with fixed part 130
It fixes on the shell, 110 edge of central part of interior fixed part 210 and vibrating diaphragm 100 is fixed, outer fixing portion 220 and interior fixed part 210
Between be connected as one by a plurality of linking arm 230.When assembling loudspeaker, need vibrating diaphragm 100 and centring disk 200 using glue
Water is bonded as one, then is bonded voice coil 300 and forms vibrational system, is then bonded vibrational system glue on the shell.Thus
As it can be seen that in the present embodiment, vibrating diaphragm 100 is used for and the knot of the combination of centring disk 200 namely vibrating diaphragm 100 and centring disk 200
Conjunction is conventional technical means to those skilled in the art.

In embodiments of the present invention, as above, vibrational system is incorporated in by vibrating diaphragm 100, centring disk 200 and voice coil 300
Together.Voice coil 300 is for protruding into the magnetic gap in magnetic circuit system, and the electric current of the connection variation of voice coil 300 is by different size of
Ampere force and vibrate, to drive the vibration of centring disk 200 and vibrating diaphragm 100 namely centring disk 200 and vibrating diaphragm 100 can be same
Shi Fasheng vibration.The centring disk 200 includes interior fixed part 210, outer fixing portion 220 and the interior fixed part 210 of connection and outer fixation
The linking arm 230 in portion 220, and since the outer fixing portion of centring disk 200 220 is used to be attached fixation, interior fixation with shell
Portion 210 with 110 edge of central part of voice coil 300 and vibrating diaphragm 100 for being fixedly connected, and therefore, vibrates and occurs in centring disk 200
When, interior fixed part 210 drives linking arm 230 to vibrate, thus the first bending interconnecting piece 231 and the second bending interconnecting piece 232 and vibration
Space between the ring portion 120 of film changes with the generation of vibration.
Specifically, when voice coil 300 vibrates upwards, vibrating diaphragm 100 and centring disk 200 vibrate upwards, interior 210 band of fixed part
The dynamic vibration upwards of linking arm 230, at this time since the first bending interconnecting piece 231 corresponds to the position that proximal edge is leaned in ring portion 120, because
The ring portion 120 of this vibrating diaphragm 100 is less than normal relative to the oscillation space at the position of the first bending interconnecting piece 231.When the folding of vibrating diaphragm 100
When ring portion 120 is less than normal relative to the oscillation space at the position of the first bending interconnecting piece 231, sounding effect certainly will be affected.
When voice coil 300 vibrates downwards, vibrating diaphragm 100 and centring disk 200 vibrate downwards, and interior fixed part 210 drives connection
Arm 230 vibrates downwards, i.e. the first bending interconnecting piece 231 vibration downwards, due to outer fixing portion 220 at this time be it is fixed, it is interior
When fixed part 210 drives linking arm 230 to vibrate downwards, the downward Oscillation Amplitude of the second bending interconnecting piece 232 is smaller, and due to the
Two bending interconnecting pieces 232 are opposite by the position of proximal edge with ring portion 120, therefore when vibrating diaphragm 100 vibrates downwards, vibrating diaphragm 100
Ring portion 120 it is less than normal relative to the oscillation space at the position of the second bending interconnecting piece 232, sounding effect is affected.
Therefore, in the present embodiment, by by ring portion 120 and the first bending interconnecting piece 231 and the second bending interconnecting piece 232
The highest point at corresponding position deviates setting.That is, the first bending connects when interior fixed part 210 drives linking arm 230 to vibrate
Socket part 231 and the second bending interconnecting piece 232 pass through the opposite of ring portion 120 there are about the one maximum position of amplitude (point)

When vibration, the oscillation space of vibrating diaphragm can be effectively ensured.
In addition, can also increase linking arm 230 and ring portion 120 between the two by the whole height for increasing ring portion 120
Oscillation space, but the whole height for being increased ring portion 120 increases the volume of entire loudspeaker also, is not easy to loudspeaking
The miniaturization of device.It is opposite by ring portion 120 and the first bending interconnecting piece 231 and the second bending interconnecting piece 232 in the present embodiment
The highest point offset setting at the position answered namely the ring portion 120 of vibrating diaphragm 110 are to the first bending interconnecting piece 231 of linking arm 230
It is formed and is avoided with the second bending interconnecting piece 232, in the case where guaranteeing that constancy of volume is big, increased oscillation space, ensure that and raise
The acoustical behavior of sound device.
Ring portion 120 is in bending, centered on 110 vibration provide certain pliable, that is, provide certain soft
Property, so that central part 110 is easier to vibrate.In addition, being avoided that vibrating diaphragm 100 by being in bending by the setting of ring portion 120

Highest point offset setting can be that the section at the corresponding position in ring portion 120 is in symmetric curvature shape, the ring portion 120
Corresponding position overall offset setting, can increase oscillation space with this.But the setting of this form will cause centering branch
The structure of piece 200 changes, that is, when ring portion 120 corresponding even the first bending interconnecting piece 231 and the second bending interconnecting piece
After 232 position overall offset, interior fixed part 210 and outer fixing portion 220 on centring disk 200 will also deviate centainly accordingly
Distance with vibrating diaphragm 100 to be combined, the problem of this be easy to cause polarization.After local offset occurs for centring disk 200, to its structure
Intensity is equally unfavorable, in some instances it may even be possible to the problem of broken by vibration occurs.Therefore, as shown in Figures 4 to 6, ring portion 120 and the first folding
The section at the corresponding position of curved interconnecting piece 231 is in asymmetrical bending, ring portion 120 and 232 phase of the second bending interconnecting piece
