For further description of receiver assembly 50, refer specifically to the description below.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a receiver assembly 50 according to an embodiment of the present disclosure. The receiver assembly 50 includes a receiver 500 and a receiver holder 510. The receiver 500 is mounted on the receiver chamber holder 510.

The receiver sound cavity holder 510 is a rectangular parallelepiped structure, and certainly, the receiver sound cavity holder 510 may also be in other shapes such as a ring shape and a hexagon, and the specific shape of the receiver sound cavity holder 510 is not specifically limited in this embodiment, but the shape of the receiver front sound cavity 504 in this embodiment is defaulted to the rectangular parallelepiped structure without special description in this embodiment.

The receiver sound cavity support 510 includes a top wall 511, a first side wall 512 and a second side wall 513, the first side wall 512 and the second side wall 513 are disposed on two sides of the top wall 511, the first side wall 512 is connected to the top wall 511, an opening is formed between the second side wall 513 and the top wall 511, the first side wall 512 extends out of the second side wall 513 to form a first protruding portion 5121, the second side wall 513 is provided with a second protruding portion 5131 opposite to the first protruding portion 5121, a gap 515 is formed between the first protruding portion 5121 and the second protruding portion 5131, a channel is formed between the second protruding portion 5131 and the top wall 511, and a sound guide tube 516 is disposed in the channel.

As shown in fig. 4, in some embodiments, the receiver 500 is disposed under the first protrusion 5121 and the second protrusion 5131, a receiver front cover 503 is disposed on a side of the receiver 500 close to the first protrusion 5121 and the second protrusion 5131, the receiver front cover 503 is disposed with sound outlet holes 5033, and the receiver front cover 503, the top wall 511 and the first sidewall 512 of the receiver sound cavity support 510 form a receiver front sound cavity 504. At present, the design of electronic equipment with large screen and small thickness has become the mainstream of current development, on this background, the thickness of the receiver 500 also needs to be reduced to meet the assembly requirement of the electronic equipment, and if the thickness of the existing receiver 500 is reduced on the whole, the sound output effect of the receiver 500 is affected, by adopting the above structure, the thickness of the receiver 500 determines the thickness of the receiver 500 of the whole machine, in order to thin the thickness of the whole machine, the thickness of the single body of the receiver 500 needs to be reduced, so the tone quality of the single body of the receiver 500 is sacrificed, and thus the tone quality of the whole machine conversation is sacrificed. Because the conventional receiver 500 is assembled in a full-screen mobile phone, the structural design of the sound guide tube 516 is required, and the volume of the front sound cavity 504 of the receiver is large, which causes the high-frequency bandwidth to be narrow, so that the conversation sound quality of the receiver 500 is unclear.

In the situation of the above problem, please refer to fig. 5 again, the present application provides a receiver assembly 50, which includes a receiver 500 and a receiver sound cavity holder 510, where the receiver 500 includes a receiver holder 501, a diaphragm 502 and a receiver front cover 503, the receiver holder 501 includes a first side 5011 and a second side 5012 opposite to the first side 5011, the diaphragm 502 is disposed near the inside of the first side 5011 of the receiver holder 501, the receiver front cover 503 is disposed outside the first side 5011 of the receiver holder 501, the receiver front cover 503 includes a protrusion 5031 protruding away from the first side 5011 of the receiver holder 501, the receiver sound cavity holder 510 includes a notch 515, and the protrusion 5031 extends into the notch 515 to form a receiver front sound cavity 504 with the receiver sound cavity holder 510.

It should be noted that the first side 5011 of the receiver support 501 is a top surface, the second side 5012 of the receiver support 501 is a bottom surface, and certainly, the first side 5011 of the receiver support 501 may be a bottom surface, and the second side 5012 of the receiver support 501 may be a bottom surface, and in this embodiment, no specific limitation is imposed on which of the first side 5011 and the second side 5012 of the receiver support 501 is located above or below.

The shape of the notch 515 is matched with the shape of the protrusion 5031, the protrusion 5031 penetrates from the lower end of the notch 515 and extends into the receiver front sound cavity 504, and the receiver front sound cavity 504 is communicated with the sound guide tube 516. The protrusion 5031 extends from the notch 515 to the front sound cavity 504 of the receiver, so as to reduce the volume of the front sound cavity 504 of the receiver, widen the high-frequency bandwidth, and make the conversation sound quality of the receiver 500 clearer. Meanwhile, the arrangement increases the volume of the sound cavity inside the receiver 500 without increasing the overall thickness of the receiver assembly 50, thereby further improving the sound output effect of the receiver 500.

By changing the structure of the receiver 500, the front cover 503 of the receiver has the protrusion 5031, and the protrusion 5031 is placed in the notch 515 to communicate with the sound guide tube 516 of the receiver 500, so as to reduce the volume of the front cavity of the receiver 500, improve the high-frequency bandwidth of the receiver 500, and improve the conversation sound quality of the mobile phone.

Referring to fig. 6, fig. 6 is a schematic structural diagram of a receiver 500 in an embodiment of the present application, where the receiver 500 includes a receiver support 501, a diaphragm 502, and a receiver front cover 503.
