Description
Technical field
The utility model is related to electroacoustic apparatus technology, more particularly to a kind of technology of moving-iron type vibrating speaker.
Background technology
Moving-iron type vibrating speaker is main by shell, and induction coil, magnetic conductive board, oscillating plate, magnetic in shell
Iron is constituted.The fixed form of part and shell in shell mainly has following two：
The first fixed form is to paste flexible material in magnetic conductive board bottom（Such as foam, silica gel）, flexible material with it is outer
Shell is pasted, due to reaction force of the shell to flexible material so when vibrating speaker works, and then flexible material is to vibration
Loudspeaker produces reaction force, and then suppresses vibrating speaker vibration so that vibrating speaker produces loss in some frequency ranges, from
And influence the tonequality of vibrating speaker.
Second of fixed form is to be screwed oscillating plate with shell, the housing pair so when vibrating speaker works
Oscillating plate has reaction force, and then suppresses vibrating speaker vibration, can also cause vibrating speaker to produce loss in some frequency ranges,
So as to influence the tonequality of vibrating speaker.
Utility model content
For defect present in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of sound
The good moving-iron type vibrating speaker of matter.
In order to solve the above-mentioned technical problem, a kind of moving-iron type vibrating speaker provided by the utility model, including shell,
And magnetic circuit component, vibration component in shell；It is characterized in that：The magnetic circuit component includes induction coil, magnetic conductive board
And two magnet, the vibration component include the first oscillating plate, the second oscillating plate；
Magnetic pole protruding upward is formed with the middle part of the magnetic conductive board, the induction coil is nested with the magnetic in the middle part of magnetic conductive board
On post, two magnet are placed in the left and right sides of induction coil；
It is fixed on after the bending downwards of the left and right ends of second oscillating plate on magnetic conductive board, first oscillating plate is fixed on
The middle part of second oscillating plate；
The shell is provided with suspension, and the suspension is made up of suspension outer portion, center of suspension portion, the suspension outer portion
In a ring, center of suspension portion is laid in the inner ring of suspension outer portion, and suspension outer portion has with center of suspension portion by many
The suspension branch connection of elasticity, the suspension branch is in many fold-line-shapeds, and the suspension outer portion is fixed on shell, the suspension
Central part is fixed on the first oscillating plate.
Part in the moving-iron type vibrating speaker that the utility model is provided, shell passes through tool by suspension connected with outer casing
Flexible many fold-line-shaped suspension branches, can improve vibratory response sensitivity, so as to lift the tonequality of loudspeaker, with sound
The characteristics of matter is good.
