Abstract:
The present invention provides a terminal device, comprising a body part and a sound generation component. The sound generation component comprises a housing movably connected to the body part and a sound generation unit accommodated in the housing. A sound generation surface of the housing is recessed to form an accommodation groove and a sound generation channel which are in communication with each other. The accommodation groove is covered by a cover plate, and the cover plate and the sound generation unit are provided at intervals to form a front acoustic cavity in communication with the sound generation channel. An inner surface and an extension surface of the body part form the accommodation groove for accommodating the sound generation component. The body part is provided with a gap extending from the inner surface to an outer surface. The sound generation component moves between a first position and a second position in the accommodation groove. When the housing is at the first position, the sound generation channel is covered by the body part, and the sound generated by the sound generation component is transmitted to the outside by means of the sound generation channel and the gap in turn. When the housing is at the second position, the sound generation channel is in communication with the outside, and the sound generated by the sound generation component is transmitted to the outside by means of the sound generation channel. The present invention solves the problem of the influence of airflow sound, piano sound, etc. on the sound effect of the terminal device in a loudspeaker mode.
