the sound production assembly moves between a first position and a second position in the accommodating groove; when the terminal device is in the first position, the sounding channel is covered by the main body part, and the sound generated by the sounding component is transmitted to the outer side of the terminal device through the sounding channel and the notch in sequence; the casing drives the sound production monomer removes extremely during the second position, at least part the sound production passageway exposes in terminal equipment, the sound production passageway with terminal equipment outside intercommunication, the sound warp that the sound production subassembly produced the sound production passageway propagates extremely the terminal equipment outside.

Further, the apron further extends and forms the cover the extension board of sound production passageway, run through on the extension board be formed with the phonation hole of sound production passageway intercommunication, the sound that the sound production monomer produced passes through in proper order the sound production passageway reaches the phonation hole is outwards propagated.

Furthermore, the sound production monomer includes the vibrating diaphragm, the vibrating diaphragm is including the ball top that is located central zone and encircle the dog-ear portion at ball top, the vibrating diaphragm with the apron interval sets up and forms preceding sound chamber.

Furthermore, the sound outlet holes are arranged on the cover plate in a matrix.

Furthermore, one side of the cover plate, which is far away from the sounding monomer, is sunken to form a limiting groove, and the sounding holes are arranged in the limiting groove in a matrix manner.

Furthermore, the groove wall of the accommodating groove extends towards the sounding single body to form a fixing part, and the fixing part is abutted to the folded ring part.

Further, the surface include with the relative front of internal surface, certainly the front edge towards the side that the internal surface direction is buckled and is extended, and connect the side is kept away from the bottom surface of front one end, the bottom surface corresponds sound production subassembly towards the sunken formation in front direction the holding tank, the internal surface extend to the side and with the side is connected, the breach extends in the side.

Further, when the sounding component is located at the first position, the back face is spliced with the bottom face and is coplanar.

The invention has the beneficial effects that: the terminal equipment comprises a main body part and a sounding assembly which are assembled in a matched mode, the sounding assembly comprises a shell and sounding single bodies, the shell is movably connected with the main body part, the sounding surface of the shell is sunken towards the back to form a containing groove and a sounding channel which are mutually communicated, the sounding single bodies are contained in the containing groove, the containing groove is covered by a cover plate, and the cover plate and the sounding single bodies are arranged at intervals to form a front sounding cavity communicated with the sounding channel; the inner surface and the extending surface of the main body part form an accommodating groove for accommodating the sounding component, and the main body part is provided with a notch extending from the inner surface to the outer surface; the sounding single body is accommodated in the accommodating groove, when the sounding assembly is located at a first position in the accommodating groove, the main body part covers the sounding channel, the sounding single body sounds, and the sound is transmitted from the notch after passing through the front sound cavity and the sounding channel, namely a telephone receiver mode of the terminal device; when the shell drives the sounding monomer to move to the second position in the accommodating groove, at least part of the sounding channel is exposed to the outside, and the sound emitted by the sounding monomer is directly transmitted to the outside through the front sound cavity and the sounding channel, namely the speaker mode of the terminal equipment; the application of the technical scheme provides two sound outlet paths under two modes of the loudspeaker and the receiver, and provides a more unobstructed sound outlet path under the loudspeaker mode, thereby improving the problem that the terminal equipment can generate airflow sound, piano sound and the like under the loudspeaker mode so as to influence the sound effect.
