Description
Technical field
The present invention relates to the suspension frame structure for high power micro-speaker, more particularly, to the shape of a kind of suspension,
Which ensure that the lightweight of suspension and high reliability and the conductive pattern of the applying signal of telecommunication.
Background technology
The audio reproduction technology of mobile multimedia is improved along with the development of mobile communication technology, it is therefore desirable to micro-
Type speaker has high-performance, high tone quality and high power.
In most of the cases, traditional Microspeaker do not use specific suspension to guarantee the lightweight of diaphragm, and
The lead-in wire of voice coil loudspeaker voice coil is connected to diaphragm, so that external electric signal is applied to voice coil loudspeaker voice coil via engaging.Accordingly, because lack suspension and warp
Often producing unbalanced vibration, and the lead-in wire of coil at high power is often out of order due to tension force, this makes miniature raising
Sound device is difficult to be applicable to high power.
In order to solve foregoing problems, having been developed for using the Microspeaker of suspension, this suspension is provided with for transmitting
The conductive pattern of the signal of telecommunication.In the case of the Microspeaker using suspension, the diaphragm weight produced due to use suspension
Increasing causes the acoustic pressure of Microspeaker to reduce.It addition, it may happen that rupture in conductive pattern at high power, thus cause
Fault.
