Specifically, the receiver body 10 is used to convert an audio electric signal into a sound signal to realize playback of audio (voice, music). In some embodiments of the present application, the receiver body 10 is a moving-coil receiver, which generally includes a voice coil, a permanent magnet and a diaphragm, the moving-coil receiver feeds a variable audio signal into the voice coil, and the voice coil vibrates up and down with the driving of a variable electromagnetic field force generated by a variable current and drives the diaphragm to drive front and rear air, so as to finally generate sound waves. It will be appreciated that the receiver body 10 may also be other types of receivers, such as bone conduction receivers.

The circuit board 20 is used for providing electrical connection for the receiver so as to supply current to the receiver body 10. Generally, in order to facilitate the installation of the receiver body 10, the circuit board 20 is provided with an installation space of the receiver body 10, and after the receiver body 10 is installed at the installation space, the receiver body 10 is not in contact with the circuit board 20, so that the vibration of the receiver body 10 can be prevented from being transmitted to the circuit board 20. By way of example, the circuit board 20 may be a single panel, a double panel, or a multilayer wiring board.

The receiver dome 30 is used to electrically connect the receiver body 10 and the circuit board 20, and the receiver dome 30 is made of a conductive material, such as copper, graphite, or the like. The receiver spring sheet 30 has a contact portion 31 and a pin portion 32, the contact portion 31 covers at least a portion of the receiver body 10 and is electrically connected to the receiver body 10, and the pin portion 32 is at least partially fixed in the insertion hole 21 and is electrically connected to the circuit board 20, so that the receiver body 10 is electrically connected to the circuit board 20. In some embodiments of the present application, the contact portion 31 is a flat plate corresponding to the receiver elastic pin 11, and the pin portion 32 is a flat plate vertically arranged, so that the receiver elastic plate 30 can be manufactured by cutting and bending a single plate, which is beneficial to reducing the processing difficulty of the receiver elastic plate 30. It will be appreciated that the contact portion 31 or the pin portion 32 may also have other shapes, for example, the pin portion 32 may have a cylindrical shape.

In the embodiment of the application, the contact portion 31 of the receiver elastic sheet 30 is electrically connected with the receiver body 10, the pin portion 32 of the receiver elastic sheet 30 is inserted into the insertion hole 21 on the circuit board 20 to realize the electrical connection with the circuit board 20, and finally the receiver elastic sheet 30 is used for conducting signals between the receiver and the circuit board 20, so that a spring sheet structure and a corresponding buckle and support structure are not required to be arranged, the connection space between the receiver and the circuit board 20 is further saved, and the volume reduction of the electronic device is facilitated; meanwhile, the electric connection is realized by replacing the flexible FPC flat cable with the telephone receiver elastic sheet 30, so that the connection structure of the circuit board and the telephone receiver is simplified, and further, the manufacturing cost of the electronic equipment can be reduced.

Further, in order to improve the connection stability between the receiver elastic sheet 30 and the circuit board 20 and avoid the phenomenon that the receiver elastic sheet 30 is separated from the circuit board 20 along with the vibration of the receiver body 10, referring to fig. 2, fig. 2 shows a schematic structural diagram of the receiver elastic sheet 30 in the embodiment of the present application, wherein the pin portion 32 includes a first pin portion 32a and a second pin portion 32b, and the first pin portion 32a and the second pin portion 32b are respectively located at two adjacent sides of the receiver body 10. When the pin portion 32 of the receiver body 10 is connected to the circuit board 20, the first pin portion 32a and the second pin portion 32b are connected to the circuit board 20 area on two adjacent sides of the receiver, so that the receiver elastic sheet 30 and the circuit board 20 have a plurality of joints, which is beneficial to improving the connection stability of the receiver elastic sheet 30 and the circuit board 20.

It can be understood that the receiver dome 30 may further have more pin portions 32 to further improve the stability of the connection between the receiver dome 30 and the circuit board 20.

In some embodiments of the present application, with reference to fig. 2, the receiver dome 30 further includes a first connecting portion 33 and a second connecting portion 34, the first connecting portion 33 connects the contact portion 31 and the first pin portion 32a, and the second connecting portion 34 connects the contact portion 31 and the second pin portion 32 b; the first connecting portion 33 and the second connecting portion 34 are respectively located at two adjacent side surfaces of the receiver body 10, and the first connecting portion 33 and the second connecting portion 34 are connected and cover a common edge of the two side surfaces.

In the above embodiment, since the first connecting portion 33 and the second connecting portion 34 are respectively located at two adjacent side surfaces of the receiver body 10, so that the movement of the receiver body 10 in the x-axis direction and the y-axis direction is limited by the first connecting portion 33 and the second connecting portion 34, and the movement in the z-axis direction is limited by the contact portion 31, the receiver elastic piece 30 can limit the movement of the receiver body 10 while achieving the electrical connection. In addition, because the first connecting portion 33 and the second connecting portion 34 are connected and cover the common edge of the two adjacent side surfaces of the receiver body 10, on one hand, the connection of the first connecting portion 33 and the second connecting portion 34 can improve the overall structural strength of the receiver elastic sheet 30, and on the other hand, the edge of the receiver body 10 can be protected, so that the phenomenon that the edge of the receiver body 10 is abraded can be prevented.

It is understood that the first pin portion 32a, the second pin portion 32b, the first connection portion 33 and the second connection portion 34 may also be disposed at other positions, for example, the first pin portion 32a and the second pin portion 32b are located at two opposite sides of the receiver body 10, and the first connection portion 33 and the second connection portion 34 are respectively located at two opposite sides of the receiver body 10, so as to electrically connect and fix the receiver body 10 in a manner of crossing the two opposite sides.

Further, in some embodiments of the present application, for example, for an embodiment in which the pin portion 32 includes a first pin portion 32a and a second pin portion 32b, one of the first pin portion 32a and the second pin portion 32b is electrically connected to the circuit board 20, and the other is in insulated contact with the circuit board 20, so as to avoid a short circuit phenomenon caused by the first pin portion 32a and the second pin portion 32b being electrically connected to the circuit board 20 at the same time.

Referring to fig. 1, the insertion hole 21 includes a first insertion hole 21a corresponding to the first pin portion 32a and a second insertion hole 21b corresponding to the second pin portion 32b, the first insertion hole 21a is provided with a conductive material contacting the first pin portion 32a, the second insertion hole 21b is provided with an insulating material covering the second pin portion 32b, the conductive material in the first insertion hole 21a electrically connects the first pin portion 32a to the circuit board 20, and the insulating material covering the second pin portion 32b prevents a short circuit phenomenon caused by the simultaneous electrical connection with the circuit board 20. Illustratively, the conductive material may be solder paste, and the insulating material may be insulating paste, etc.

As an exemplary structure of the pin unit 32, with reference to fig. 2, the pin unit 32 has a horizontal portion 321 and a vertical portion 322, the vertical portion 322 of the pin unit 32 is inserted into the insertion hole 21, and the horizontal portion 321 is attached to the surface of the circuit board 20. Because vibration is transmitted to the receiver elastic sheet 30 when the receiver body 10 works, the receiver elastic sheet 30 is prone to shake, and thus the receiver elastic sheet 30 and the receiver elastic pins 11 are in poor electrical contact, and in this embodiment, the middle pin portion 32 has a horizontal portion 321 and a vertical portion 322, and the horizontal portion 321 is attached to the surface of the circuit board 20 to weaken the shake of the receiver elastic sheet 30, so as to ensure good electrical contact between the receiver elastic sheet 30 and the receiver elastic pins 11.

In some embodiments of the present application, referring to fig. 1, the receiver body 10 has two receiver pins 11, the two receiver pins 11 are respectively used as a positive electrode and a negative electrode of the receiver body 10, and the receiver pins 11 are in contact with the receiver spring 30 to achieve electrical conduction. Generally, the receiver elastic pin 11 has elasticity to prevent the receiver body 10 from directly transmitting vibration rigidity to the receiver elastic piece 30 during vibration.

In some embodiments of the present application, for example, for the embodiment that the receiver body 10 has two receiver elastic pins 11, referring to fig. 2, the receiver elastic piece 30 includes a first elastic piece 30a and a second elastic piece 30b, the first elastic piece 30a and the second elastic piece 30b are adjacently disposed, and two adjacent corners of the receiver body 10 are fixed, so as to improve the structural stability of the receiver body 10.

It can be understood that the first elastic piece 30a and the second elastic piece 30b may be arranged in other manners, for example, the first elastic piece 30a and the second elastic piece 30b are arranged diagonally and fix two opposite corners of the receiver body 10.

Further, in order to keep the good contact between the receiver body 10 and the receiver elastic sheet 30, refer to fig. 2, fig. 3 and fig. 4 continuously, fig. 3 shows a top view of the receiver connection structure in the embodiment of the present application, fig. 4 shows a cross-sectional schematic view at a-a in fig. 2 of the present application, wherein the contact portion 31 of the receiver elastic sheet 30 is provided with a through fixing hole 311, and the receiver elastic leg 11 is at least partially embedded into the fixing hole 311, so that the receiver elastic leg 11 can be fixed in the fixing hole 311 of the contact portion 31, thereby avoiding the phenomenon that the receiver elastic leg 11 is separated from the contact portion 31 due to the split vibration of the receiver.

It should be noted that the above description of the receiver connecting structure is only for clearly illustrating the verification process of the present application, and those skilled in the art can make equivalent modified designs for the receiver connecting structure under the guidance of the present application, for example, four receiver elastic sheets 30 may be provided, and four receiver elastic sheets 30 are respectively fixed at four corners of the receiver body 10.
