The sound guide channel 13 may be a T-shaped channel or other irregularly shaped channels. The sound guide channel 13 and the housing 1 may be integrally formed or may be non-integrally formed. The receiver accommodating chamber 14 and the housing 1 may be integrally formed or non-integrally formed.

In the embodiment of the present invention, the propagation path of the sound emitted from the receiver 2 in the sound guide channel 13 may be as shown by the arrow in fig. 1. The sound outlet surface 21 of the receiver 2 faces the sound guide channel 13, so that the sound outlet quality of the terminal is better, and specifically, the obtained sound is clearer and louder.

In the embodiment of the invention, the sound guide channel is respectively communicated with the receiver accommodating cavity, the first sound outlet and the second sound outlet, the receiver is arranged in the receiver accommodating cavity, and the sound outlet surface of the receiver faces the sound guide channel, so that the sound emitted by the receiver can be respectively transmitted to the first sound outlet and the second sound outlet which are positioned at two opposite sides of the shell through the sound guide channel, and thus, the answering functions of the front side and the back side of the terminal can be realized only by arranging one receiver, and the assembly space of the terminal can be saved. Meanwhile, as the number of parts is reduced, the failure rate of the terminal can be reduced, and the cost can be reduced.

In addition, on one hand, because the receiver is obliquely arranged between the two opposite sides of the shell 1, the sound outlet surface 21 of the receiver is obliquely arranged relative to the sound guide channel 13, so that sound waves emitted by the sound outlet surface 21 can be reflected for multiple times in the sound guide channel 13, sound is amplified in the sound guide channel 13, and the sound outlet effect of the receiver can be improved. On the other hand, because the telephone receiver is obliquely arranged, the thickness space occupied by the telephone receiver can be reduced, and the terminal is favorable for the development of lightness and thinness.
