Abstract
The invention discloses a compact moving-iron telephone receiver. The compact moving-iron telephone receiver comprises an electromagnetic shielding shell, a diaphragm, a coil and a PCB board. The compact moving-iron telephone receiver is characterized in that the electromagnetic shielding shell is composed of an upper cover and a lower cover which are buckled together. The diaphragm is fixed in the upper cover and is used for dividing the internal space of the electromagnetic shielding shell into a front cavity and a rear cavity. The space formed between the diaphragm and the top board of the upper cover is the front cavity. The residual space in the electromagnetic shielding shell is the rear cavity. The lengths of the rear ends of the upper cover and the lower cover are different. The rear ends of the upper cover and the lower cover are connected through a step surface. The PCB board is fixed on the step surface. The PCB board is moved out from the tail end of the product, and therefore, the internal space of the rear cavity is greater. Compared with the telephone receiver in the prior art, the compact moving-iron telephone receiver has the advantages that under the condition that the effective volumes of the rear cavities are the same, the external size of the product is enabled to be smaller, the telephone receiver can be applied to the smaller space, the application range is wide, and moreover, the quality of the telephone receiver is ensured.

Chamber, the internal remaining space of electromagnetic shielding shell is back cavity；Upper cover is different with lower cover back-end length, upper cover with
Lower cover back-end is connected by step surface, and pcb board is fixed on step surface.
Pcb board is removed from product end, the inner space of back cavity can be made more to strengthen, with prior art
In receiver compare, under back cavity effective volume same case, the external dimensions of product can be done more
Little, make receiver can apply in less space, range of application is wider, ensure that receiver's matter simultaneously
Amount.In the case of product external dimensions is identical, the effective volume within back cavity is bigger, is conducive to promoting and moves
The low frequency sensitivity of ferrum receiver, reduces low-frequency distortion, can carry out spy for the different demands of different product
Different design.
As a kind of preferred version of Novel receiver of the present invention, step surface has perforate, coil
Lead-in wire through perforate and be welded on the pcb board on step surface,
As a kind of preferred version of Novel receiver of the present invention, described upper cover and lower cover width phase
With, telephone receiver structure is more symmetrical, is suitable on the product that installing space is more regular using.
As a kind of preferred version of Novel receiver of the present invention, described upper cover and lower cover width not
With, according to practical situation, adjust upper cover or the width of lower cover, it is achieved ante-chamber and the change of rear cavity space, enter
And change the performance of receiver, on the irregular product of some installing spaces, this receiver makes space utilization
Rate is higher, and product structure is compacter.
As a kind of preferred version of Novel receiver of the present invention, described upper cover back-end length is less than
Lower cover back-end length, the end face of lower cover back-end is step surface, and pcb board is fixed on this step surface.
As a kind of preferred version of Novel receiver of the present invention, described upper cover back-end length is more than
Lower cover back-end length, the bottom surface of upper cover back-end is step surface, and pcb board is fixed on this step surface.
Beneficial effect:
Novel receiver disclosed by the invention, by improving electromagnetic shielding shell shape, and by PCB
Plate is fixed on outside electromagnetic shielding shell, and under conditions of receiver's equal length, ante-chamber or back cavity can set
That counts is bigger, can improve the low frequency sensitivity of receiver response curve, reduce distortion, such that it is able to design
Go out the receiver of more excellent performance.
