Abstract: A middle frame includes: a border antenna which is provided with a sound output hole, a first mounting site for arranging a circuit board which is connected with a feed point of the border antenna, and a second mounting site for arranging an audio assembly which is connected with the sound output hole through a sound output channel, the first mounting site is between the border antenna and the second mounting site.

Abstract: A housing member and an electronic device are provided. The housing member is configured to accommodate a receiver audio assembly, and includes a rear shell, a middle frame and a sound transmission gap for sound transmission. The rear shell and the middle frame define an accommodating cavity for accommodating the receiver audio assembly, the accommodating cavity is provided with an opening for sound transmission, and the opening is opposite to the rear shell. The middle frame is provided with a sound transmission channel for communicating the opening of the accommodating cavity with the sound transmission gap. The electronic device includes the receiver audio assembly and the housing member. The receiver audio assembly is fixed in the accommodating cavity. The sound exiting direction of the receiver audio assembly is opposite to the rear shell and coincides with a direction of the opening of the accommodating cavity.
