MOBILE TERMINAL Russian patent published in 2022 - IPC H04M1/03 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of structural elements of mobile telephone devices. To realise the technical result, a mobile terminal consisting of a body (100) with an internal cavity (110) and a receiver (200) located in the internal cavity (110), wherein the internal cavity (110) comprises the front cavity of the receiver (111) and the back cavity of the receiver (112), isolated from each other; the front cavity of the receiver (111) and the back cavity of the receiver (112) are located on the front and back sides of the receiver (200), respectively, in the direction of vibration of the diaphragm of the receiver (200); the body (100) is equipped with a first resonator hole in communication with the front cavity of the receiver (111), and the body (100) is equipped with a second resonator hole in communication with the back cavity of the receiver (112). The mobile terminal therein additionally comprises a sealing ring (500), wherein the sealing ring (500) is located in the back cavity of the receiver (112) and encircles the receiver (200) in order to reduce the space in the back cavity of the receiver (112).

EFFECT: reduction in the difference between the sound transmitted through the first acoustic hole coupled with the front cavity of the receiver and the sound transmitted through the second acoustic hole coupled with the back cavity of the receiver.
