The present embodiment is one of all embodiments, specifically, the electromagnetic pole 52 has two, a first electromagnetic pole 521 and a second electromagnetic pole 522, the two electromagnetic poles 52 are independent of each other and are not connected and contacted with the electromagnetic pole 52; the magnetic pole surface of the first electromagnetic pole 521 is arranged opposite to the magnetic pole surface of the second electromagnetic pole 522, in other words, the magnetic pole surface of the first electromagnetic pole 521 is arranged opposite to the magnetic pole surface of the second electromagnetic pole 522; the first electromagnetic pole 521 is arranged on one side of the earphone sound outlet channel 31 away from the loudspeaker sound outlet channel 32, and the second electromagnetic pole 522 is arranged on one side of the loudspeaker sound outlet channel 32 away from the earphone sound outlet channel 31; specifically, since the earphone sound outlet channel 31 and the speaker sound outlet channel 32 are independent and spaced apart by a certain distance, the earphone sound outlet channel 31 includes a side close to the speaker sound outlet channel 32 and also includes a side far from the speaker sound outlet channel 32; the loudspeaker sound outlet channel 32 is the same; in this embodiment, the first electromagnetic pole 521 is disposed at the earphone sound outlet channel 31 and away from one side of the loudspeaker sound outlet channel 32, and the second electromagnetic pole 522 is disposed at the loudspeaker sound outlet channel 32 and away from one side of the earphone sound outlet channel 31, so that the first electromagnetic pole 521 and the second electromagnetic pole 522 are spaced at a certain distance and do not interfere with each other.

In addition, in the present embodiment, the first electromagnetic pole 521 or the second electromagnetic pole 522 may be alternately energized to generate a magnetic force, where the alternate energization means that the first electromagnetic pole 521 and the second electromagnetic pole 522 are not energized at the same time, the first electromagnetic pole 521 is energized, and the second electromagnetic pole 522 is de-energized; the first electromagnetic pole 521 is de-energized and the second electromagnetic pole 522 is energized; at this time, in one embodiment, the number of the valves 51 is one; wherein the valve 51 is driven by the driving part to move between the receiver sound outlet channel 31 and the speaker sound outlet channel 32. In another embodiment, the number of valves 51 is two, including a first valve 51 and a second valve 51; wherein the first valve 51 is used to cut off the earpiece sound outlet channel 31 and the second valve 51 is used to cut off the horn sound outlet channel 32.

In this embodiment, one valve 51 is disposed between the earphone sound outlet channel 31 and the speaker sound outlet channel 32, when the speaker mode needs to be implemented, the first electromagnetic pole 521 is powered on, the second electromagnetic pole 522 is powered off, the first electromagnetic pole 521 generates magnetic force and adsorbs the valve 51 to move toward the first electromagnetic pole 521, because the first electromagnetic pole 521 is disposed close to the earphone sound outlet channel 31, when the valve 51 moves toward the earphone sound outlet channel 31, the earphone sound outlet channel 31 is closed, and the second electromagnetic pole 522 is powered off and does not generate magnetic force and cannot adsorb the valve 51, so the speaker sound outlet channel 32 is opened and communicated with the sound cavity 40, and the sound generated by the earphone speaker 20 is output from the speaker sound outlet channel 32, thereby implementing the speaker mode; when the earphone mode needs to be switched, the first electromagnetic pole 521 and the second electromagnetic pole 522 are switched to be powered off, the second electromagnetic pole 522 is powered on, the second electromagnetic pole 522 generates magnetic force and adsorbs the valve 51 to move towards the second electromagnetic pole 522, because the second electromagnetic pole 522 is arranged close to the loudspeaker sound outlet channel 32, the valve 51 moves towards the loudspeaker sound outlet channel 32 from the original earphone sound outlet channel 31, the loudspeaker sound outlet channel 32 is finally closed, at the moment, the first electromagnetic pole 521 cannot generate magnetic force when being powered off, the first electromagnetic pole 521 cannot adsorb the valve 51, and the valve 51 is adsorbed to the loudspeaker sound outlet channel 32 from the second electromagnetic pole 522 at the moment, so the earphone sound outlet channel 31 is opened and communicated with the sound cavity 40, and the sound generated by the earphone 20 is output from the earphone sound outlet channel 31, thereby realizing the earphone mode.

As can be seen from the above technical solutions, the valve 51 has one, and the working principle of switching the receiver mode and the speaker mode between one valve 51 and two electromagnetic poles 52 is explained, but in other technical solutions, the sound outlet channel 30 may also have two or more valves 51; whether the valve 51 has one, two or more, the valve 51 can rotate or turn, and can also push and pull or slide; when one valve 51 is provided, if the valve 51 rotates (turns over) or slides (pushes and pulls), when the first electromagnetic pole 521 is energized, the valve 51 rotates or slides in the direction of the first electromagnetic pole 521, so as to close the earphone sound outlet channel 31, thereby implementing a speaker mode; when the second electromagnetic pole 522 is energized, the valve 51 rotates or slides in the direction of the second electromagnetic pole 522, thereby closing the speaker sound outlet channel 32 and implementing the receiver mode. When the number of the valves 51 is two, the first valve 51 and the second valve 51 are included, the first valve 51 is disposed near the earpiece sound outlet channel 31 for closing the earpiece sound outlet channel 31, the second valve 51 is disposed near the horn sound outlet channel 32 for closing the horn sound outlet channel 32, and the first valve 51 and the second valve 51 may also rotate or turn over, or may also push or pull or slide. If the valve 51 rotates (turns over) or slides (pushes and pulls), the first electromagnetic pole 521 is energized, and the first valve 51 rotates or slides in the direction of the first electromagnetic pole 521, so as to close or open the earphone sound outlet channel 31; when the second electromagnetic pole 522 is energized, the second valve 51 rotates or slides in the direction of the second electromagnetic pole 522, thereby closing or opening the horn outlet passage 32.

In one embodiment, the switching assembly 50 further comprises: one or more rotating shafts 53; the valve 51 is mounted on a rotating shaft 53 and can rotate around the rotating shaft 53. In one embodiment, the extension direction of the earpiece sound outlet channel 31 and the extension direction of the horn sound outlet channel 32 are parallel; the axis of the rotation shaft 53 is perpendicular or parallel to the extending direction of the sound outlet channel 30.

The switching assembly 50 includes a rotating shaft 53, and the rotating shaft 53 is used for mounting the valve 51, so that the valve 51 can rotate around the rotating shaft 53, and therefore the switching assembly 50 includes the rotating shaft 53 corresponding to the technical scheme that the valve 51 can rotate.

The extension direction of the earpiece sound outlet channel 31 is parallel to the extension direction of the horn sound outlet channel 32, the axis of the rotating shaft 53 is perpendicular to or parallel to the extension direction of the sound outlet channel 30, in other words, when the axis of the rotating shaft 53 is parallel to the axis of the sound outlet channel 30, the valve 51 on the rotating shaft 53 rotates around the rotating shaft 53 on a plane parallel to the radial cross section of the sound outlet channel 30, and can rotate from the lower part of the earpiece sound outlet channel 31 to the horn sound outlet channel 32, and can rotate from the upper part of the earpiece sound outlet channel 31 to the horn sound outlet channel 32, wherein "upper" and "lower" are relative positions for distinguishing the description of the positions, and in fact, the expressions such as "upper" and "lower" can be completely used interchangeably. For example, an upper side can also be referred to as a lower side, and similarly, a lower side can also be referred to as an upper side, without departing from the scope of the present disclosure.

When the axis of the rotating shaft 53 is perpendicular to the axis of the sound outlet channel 30, the valve 51 is parallel to the radial cross section of the sound outlet channel 30 when the receiver sound outlet channel 31 is closed or the horn sound outlet channel 32 is closed, but when the rotation is switched between the receiver sound outlet channel 31 and the horn sound outlet channel 32, the valve 51 forms an angle with the radial cross section of the sound outlet channel 30.

The electromagnetic poles 52 are two, the valve 51 is controlled to close the earphone sound outlet channel 31 or the loudspeaker sound outlet channel 32 by switching energization, at this time, the valve 51 has one or two, or a plurality of valves, the number and the position of the valves 51 can be selected according to design requirements, and the number, the position and the position relation of the rotating shaft 53 and the axis of the sound outlet channel 30 can also be selected according to design requirements, so that the number and the position of the valves 51 and the rotating shaft 53 can be flexibly selected and combined, when one position of the sound outlet channel 30 cannot be set due to the limitation of design requirements of other parts, the function of the valve 51 for closing the earphone sound outlet channel 31 or the loudspeaker sound outlet channel 32 is still not influenced by the selection of the positions or the number, in addition, the selection of the valves 51 and the rotating shaft 53 can be flexibly set according to the complicated and narrow space inside the terminal equipment, the method is used for reducing the internal storage space of the terminal equipment and meeting the pursuit of users on the design of the light and thin terminal.
