Put in one end of the electromagnetic shielding shell near sender；The magnetic driving mechanism includes connecting rod, tongue, the iron blade of a sword, magnet, line
Circle, pcb board, damping structure is provided with around at least a portion of tongue, and sound timbre effect is improved with this, makes sound
It is more compliant, improve the sense of hearing of user.
As a kind of preferred scheme of the receiver with damping structure described in the utility model, described damping structure
It is made up of adhesive sticker, due to the stickiness and not dry characteristic of adhesive sticker, increased the damping of vibration reed.
Further, adhesive sticker is arranged between tongue and the iron blade of a sword or between tongue and coil or tongue
Between electromagnetic shielding shell.
As a kind of preferred scheme of the receiver with damping structure described in the utility model, described damping structure
Magnetic fluid is made, and further, damping structure is arranged between tongue and magnet, and magnetic current is injected between magnet and tongue
Body, magnetic fluid can be adsorbed between tongue and magnet under its magnetic action, will not roll down to moving-iron receiver inside other
Space.Magnetic fluid between tongue and magnet, increased the damping of vibration reed.
As a kind of preferred scheme of the receiver with damping structure described in the utility model, described damping structure
It is the damping screen of mesh medium.
Further, damping screen may be mounted at following several positions：
1：Installed in the inwall of receiver sender, i.e., the inside of upper lid；
2：Installed in the outer wall of receiver sender, i.e., the outside of upper lid；
3：May be mounted at the inside of sound tube；
4：Servicing unit can be utilized to be arranged on the outside of sound tube.
Beneficial effect：
The disclosed receiver with damping structure of the utility model, by the setting of damping structure, iron is moved in effectively adjustment
The frequency response curve of receiver, can be designed that the moving-iron receiver of more excellent performances, improve the experience of user's sense of hearing.
