Technical Field

[0001] The present disclosure relates to the field of electronic audio technology, and in particular to an earpiece speaker sound output component and a terminal device. Background Art

[0002] At present, electronic terminal devices such as mobile phones and tablets have become an indispensable part of people's daily lives. People's pursuit of high-quality audio and video in terminal devices is also getting higher and higher, and stereo has become a standard feature of high-end electronic terminal products. Stereo requires at least two independent sound chambers, that is, one of the speakers also serves as an earpiece. However, in related technologies, the power difference between the earpiece and the speaker of the terminal device is large, that is, the sound volume and loudness are very different. Using the earpiece as a second speaker cannot guarantee privacy in the earpiece mode, nor can it achieve the expected stereo effect. Therefore, there is an urgent need for a technical solution that allows the earpiece and speaker to have different sound output channels in different application modes, and the sound output does not interfere with each other. Summary of the Invention

[0018] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0019] Figure 1 It is a schematic diagram showing an earpiece speaker sound output component realizing a speaker function according to an exemplary embodiment.

[0020] Figure 2 The figure is a schematic diagram showing an earpiece speaker sound output component realizing an earpiece function according to an exemplary embodiment. DETAILED DESCRIPTION

[0021] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0022] An embodiment of the present disclosure provides an earpiece speaker sound output component, comprising: a shell 10; an earpiece speaker, disposed in the shell 10, capable of realizing an earpiece mode and a speaker mode, with a sound cavity 40 formed between the earpiece speaker 20 and the shell 10; a sound output channel 30, disposed in the shell 10, the sound output channel 30 including an earpiece sound output channel 31 and a speaker sound output channel 32; a switching component 50, for controlling at least one of the earpiece sound output channel 31 and the speaker sound output channel 32 to be connected to the sound cavity 40.

[0023] The housing 10 may be a separate housing 10 provided for the earpiece speaker 20 sound output component, or may be a partial structure inside the terminal device for mounting the earpiece speaker sound output component.

[0024] The handset speaker 20 is a two-in-one speaker that can serve as both a handset and a speaker. It can be installed at the top of a terminal device. The handset sound channel 31 can be aligned with the speaker sound channel 32, meaning they can be located on the same plane as the terminal device. The handset sound channel 31 can also be positioned away from the speaker sound channel 32, meaning the handset sound channel 31 and the speaker sound channel 32 extend in different directions, and the handset sound channel 31 and the speaker sound channel 32 are located on different planes of the terminal device. Furthermore, the speaker sound channel 32 can be positioned adjacent to the handset sound channel 31 or positioned at a greater distance from it. The terminal device can be a mobile electronic device such as a mobile phone or tablet. When the terminal device is placed to the ear for listening during a call, the handset mode is activated and the speaker mode is disabled. This prevents the sound emitted by the handset speaker 20 in handset mode from being played back and potentially being heard by anyone other than the caller, thereby ensuring the privacy of the call. When the call needs to be played back, audio needs to be listened to, or videos need to be viewed, the speaker mode is activated, thereby increasing the volume and ensuring the appropriate level of volume. Furthermore, the handset speaker 20 can be located within the housing 10 or on the circuit board of the terminal device, i.e., the bottom of the handset speaker 20 is fixed to the circuit board of the terminal device, while the sound outlet of the handset speaker 20 faces and is located within the housing 10, allowing sound to be output through the housing 10. A sound cavity 40 is formed between the handset speaker 20 and the housing 10. The sound cavity 40 supplements the handset speaker 20 and modifies the sound, making the sound richer and more robust, thereby ensuring the fullness of the sound emitted by the handset speaker 20.

[0025] As the name suggests, the sound outlet channel 30 is a pipe structure with a through channel. The fact that the sound outlet channel 30 is provided on the housing 10 means that the sound outlet channel 30 can be a separate component or a component of the housing 10. When the sound outlet channel 30 is a separate component, the housing 10 has a sound input port, and the sound outlet channel 30 is provided at the sound input port of the housing 10. At this time, the sound emitted by the earpiece speaker 20 is emitted in sequence through the sound cavity 40, the sound input port of the housing 10, and the sound outlet channel 30. In this embodiment, the sound outlet channel 30 is a component of the housing 10, and the sound outlet channel 30 has an earpiece sound output channel 31 and a speaker sound output channel 32. Both the earpiece sound output channel 31 and the speaker sound output channel 32 are tubular structures. The earpiece sound outlet channel 31 and the speaker sound outlet channel 32 are separate channels separated by a certain distance. Specifically, the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 each have an independent earpiece sound outlet channel 31 inner wall and speaker sound outlet channel 32 inner wall, and the inner walls of the two are not shared. In this embodiment, part of the component structure of the shell 10 is located between the earpiece sound outlet channel 31 and the speaker sound outlet channel 32, so that the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 are separated by a certain distance; but the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 can both be connected to the sound cavity 40, so that the sound emitted by the earpiece speaker 20 can be emitted from at least one of the earpiece sound outlet channel 31 and the speaker sound outlet channel 32.

[0026] In addition, in the speaker mode, the earpiece speaker 20 forms a dual sound cavity together with the speaker at the bottom of the terminal device. Since the speaker sound output channel 32 and the earpiece sound output channel 31 are two independent sound output channels, the outlet side of the speaker sound output channel 32 can be set at a preset position of the terminal device according to design requirements, including the front, back, upper side, left side or right side of the terminal device, so that it is coordinated with the position of other speakers of the terminal device to meet the consistency of high-frequency resonance frequency and the same frequency response, thereby achieving the best stereo sound effect and satisfying people's pursuit of high-quality audio and video.

[0027] The shapes of the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 can be circular channels, square channels, rectangular channels, diamond channels, triangular channels, or irregular channels designed according to design requirements.

[0028] The switching component 50 is used to control at least one of the earpiece sound output channel 31 and the speaker sound output channel 32 to be connected to the sound cavity 40, specifically, including the following three situations: the earpiece sound output channel 31 is connected to the sound cavity 40, the speaker sound output channel 32 is connected to the sound cavity 40, and the earpiece sound output channel 31 and the speaker sound output channel 32 are connected to the sound cavity 40 at the same time; when the earpiece sound output channel 31 is connected to the sound cavity 40, the switching component 50 opens the earpiece sound output channel 31 to connect it to the sound cavity 40, and at the same time closes the speaker sound output channel 32 to disconnect it from the sound cavity 40, so that the sound emitted by the earpiece speaker 20 is emitted through the earpiece sound output channel 31, realizing the earpiece function; when the speaker sound output channel 32 is connected to the sound cavity 40, the switching component 50 switches The speaker sound output channel 32 is switched on to be connected to the sound cavity 40, and the earpiece sound output channel 31 is switched off to be disconnected from the sound cavity 40, so that the sound emitted by the earpiece speaker 20 is emitted through the speaker sound output channel 32; when the earpiece sound output channel 31 and the speaker sound output channel 32 are connected to the sound cavity 40 at the same time, the switching component 50 opens the earpiece sound output channel 31 and the speaker sound output channel 32 at the same time, and both are connected to the sound cavity 40. At this time, the sound emitted by the earpiece speaker 20 can be emitted by the earpiece sound output channel 31 and the speaker sound output channel 32 at the same time; from the above, it can be seen that when the speaker sound output channel 32 is connected to the sound cavity 40 and the earpiece sound output channel 31 and the speaker sound output channel 32 are connected to the sound cavity 40 at the same time, the earpiece speaker 20 can realize the speaker function.

[0029] The earpiece speaker 20 is a two-in-one speaker with both earpiece and speaker functions; a sound cavity 40 is formed between the earpiece speaker 20 and the shell 10, which is used to correct the sound emitted by the earpiece speaker 20; the sound emitted by the earpiece speaker 20 is output from the sound output channel 30 on the shell 10, and the switching component 50 and the independent and spaced earpiece sound output channel 31 and speaker sound output channel 32 on the sound output channel 30 can enable the earpiece speaker 20 to close the speaker sound output channel 32 when the earpiece mode is turned on, so that the sound of the earpiece speaker 20 cannot be leaked from the speaker sound output channel 32 when in the earpiece mode, thereby ensuring the privacy of the earpiece; when the speaker mode is turned on, the speaker sound output channel 32 is opened.

[0030] In one embodiment, the switching assembly 50 includes: one or more valves 51 for cutting off the earpiece sound output channel 31 or the speaker sound output channel 32; and a driving component for driving the valve 51 to move.

[0031] As can be seen from the above, the switching assembly 50 is used to control the communication between at least one of the earpiece sound output channel 31 and the speaker sound output channel 32 and the sound cavity 40. Therefore, a valve 51 is required to close or open the earpiece sound output channel 31 and the speaker sound output channel 32. In this embodiment, the switching assembly 50 includes one or more valves 51. When there is only one valve 51 and the earpiece sound output channel 31 and the speaker sound output channel 32 are aligned, one valve 51 is located at one of the inlet, outlet, and center of the sound output channel 30. When the earpiece sound output channel 31 and the speaker sound output channel 32 are not aligned, one valve 51 is located between the inlet of the earpiece sound output channel 31 and the inlet of the speaker sound output channel 32. When there are two valves 51, they include a first valve and a second valve. The first valve is located at one of the inlet, outlet, and center of the earpiece sound output channel 31; the second valve is located at one of the inlet, outlet, and center of the speaker sound output channel 32.

[0032] In other words, when the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 are side by side, whether there is one valve 51 or multiple valves 51, the valve 51 can be located at any position on the inlet side, outlet side, or middle part of the sound outlet channel 30. When the extension direction of the earpiece sound outlet channel 31 is different from the extension direction of the speaker sound outlet channel 32, the position of the valve 51 can be set according to the number of valves 51. When the number of valves 51 is one, the valve 51 is located between the inlet side of the earpiece sound outlet channel 31 and the inlet side of the speaker sound outlet channel 32, thereby achieving switching between the two channels. When the number of valves 51 is two, one valve 51 can be set in each of the earpiece sound outlet channel 31 and the speaker sound outlet channel 32. In this case, the valve 51 can be set at any position on the inlet side, outlet side, or middle part of each sound outlet channel.

[0033] The following will describe in detail various embodiments in which the earpiece sound output channel 31 and the speaker sound output channel 32 are arranged side by side.

[0034] The switching component 50 may include one valve 51 or multiple valves 51. The details are as follows:

[0035] When the switching component 50 includes a valve 51, the valve 51 can be moved between the earpiece sound output channel 31 and the speaker sound output channel 32, thereby closing one of the earpiece sound output channel 31 and the speaker sound output channel 32. Specifically, when the valve 51 closes the earpiece sound output channel 31, it cannot close the speaker sound output channel 32, and the sound is output from the speaker sound output channel 32, realizing the speaker mode; when the valve 51 closes the speaker sound output channel 32, it cannot close the earpiece sound output channel 31, and the sound is output from the earpiece sound output channel 31. Output to achieve the handset mode; or, when the switching component 50 includes a valve 51, this valve 51 moves at the speaker sound output channel 32, thereby being used to close or open the speaker sound output channel 32. It can be seen that the handset sound output channel 31 is in a normally open state, and is normally connected to the sound cavity 40. The speaker sound output channel 32 is closed by the valve 51 to achieve the handset mode; the speaker sound output channel 32 is opened by the valve 51. At this time, the speaker sound output channel 32 and the handset sound output channel 31 are both connected to the sound cavity 40 to achieve the speaker mode.

[0036] When the switching component 50 includes multiple valves 51, in one embodiment, it includes two valves 51, and a valve 51 is set at the position of the earpiece sound output channel 31 and the speaker sound output channel 32, and each valve 51 controls the corresponding sound output channel 30; when the earpiece mode needs to be implemented, the valve 51 of the earpiece sound output channel 31 is opened, the earpiece sound output channel 31 is connected with the sound cavity 40, so that the sound emitted by the earpiece speaker 20 is output by the earpiece sound output channel 31, and at this time the valve 51 of the speaker sound output channel 32 is closed; when the speaker mode needs to be implemented, the valve 51 of the speaker sound output channel 32 is opened, the speaker sound output channel 32 is connected with the sound cavity 40, and the sound emitted by the earpiece speaker 20 is output by the speaker sound output channel 32, and at this time the valve 51 of the earpiece sound output channel 31 can be closed or opened. In addition, in one embodiment, the switching component 50 may include more than two valves 51. In one embodiment, one valve 51 is set in the earpiece sound output channel 31, two valves 51 are set in the speaker sound output channel 32, or two valves 51 are set in the earpiece sound output channel 31 and the speaker sound output channel 32. Specifically, in the earpiece mode, the speaker sound output channel 32 needs to be closed, and the two valves 51 located in the speaker sound output channel 32 are closed at the same time. The valves 51 of the speaker sound output channel 32 are closed at the same time, which further seals the speaker sound output channel 32, further hinders the connection between the speaker sound output channel 32 and the sound cavity 40, avoids sound leakage from the speaker sound output channel 32, and ensures privacy in the earpiece mode; the same applies to the speaker mode.

[0037] The driving component, i.e., the power source for driving the valve 51, can be a hydraulic piston drive, an electric motor drive, or an electromagnetic drive. With a hydraulic piston drive, the valve 51 can be mounted on a slide rail or a slide slot, and the sound outlet channel 30 can be closed or opened by pushing or pulling the piston. With an electric motor drive, the valve 51 can also be mounted on a slide rail or a slide slot, and the motor transmits power to the valve 51 located on the slide rail or the slide slot via a gear rack. With an electromagnetic drive, the valve 51 can be mounted in conjunction with a rotating shaft or a slide rail or a slide slot. When energized, the electromagnetic pole 52 generates a magnetic force to attract the valve 51, causing the valve 51 to rotate or slide. The driving component driving the valve 51 to move means that the driving component can act on the valve 51, and the power generated by the driving component drives the valve 51 to move by pushing, pulling, or attracting. The valve 51 can be a rotating valve 51 or a push-pull valve 51. The rotating valve 51, i.e., the valve 51 moves in a flipping or rotating manner. In flipping or rotating arrangements, the valve 51 is mounted in conjunction with a rotating shaft. In push-pull arrangements, the valve 51 is mounted in a sliding or push-pull manner, causing the valve 51 to slide or slide.

[0038] As terminal devices tend to be smaller and thinner, the valve 51 is used to control the closing and opening of the earpiece sound output channel 31 and the speaker sound output channel 32, which occupies a small volume of the terminal device and has low cost. In addition, the valve 51 has a simple structure, and the operation of using the valve 51 to close the channel is more convenient and easy to implement, which is more suitable for thin and small terminal devices.

[0039] In one embodiment, the valve 51 is disposed at any of the following positions of the sound output channel 30 : the inlet side of the sound output channel 30 , the outlet side of the sound output channel 30 , or the middle of the sound output channel 30 .

[0040] Regardless of whether the switching component 50 includes one valve 51 or multiple valves 51, the valves 51 of the switching component 50 can be set on the inlet side of the sound output channel 30, the outlet side of the sound output channel 30, or the middle part of the sound output channel 30. The inlet side of the sound output channel 30 refers to the side of the sound output channel 30 close to the sound cavity 40, and the sound of the sound cavity 40 enters the sound output channel 30 from the inlet side of the sound output channel 30. The outlet side of the sound output channel 30 refers to the side of the sound output channel 30 away from the sound cavity 40, and the sound entering the sound output channel 30 is transmitted from the outlet side. The middle part of the sound output channel 30 refers to the sound output channel 30 located between the inlet side and the outlet side of the sound output channel 30. Since the sound output channel 30 includes the earpiece sound output channel 31 and the speaker sound output channel 32, the corresponding earpiece sound output channel 31 and the speaker sound output channel 32 also have an inlet side, an outlet side, and a middle part, and their positional relationship with the sound cavity 40 is the same as the positional relationship between the sound output channel 30 and the sound cavity 40.

[0041] Regardless of whether the valve 51 is located at the inlet side, outlet side or middle of the sound outlet channel 30, the valve 51 can be rotated (flipped), slid (pushed and pulled), or a combination of rotation and sliding settings. Specifically, when there is one valve 51, one valve 51 can be rotated and slid at the inlet side, outlet side or middle of the sound outlet channel 30; or one valve 51 can be rotated and slid at the inlet side, outlet side or middle of the speaker sound outlet channel 32; when there are two valves 51 and they are used to close the earpiece sound outlet channel 31 and the speaker sound outlet channel 32 respectively, the valve 51 of the earpiece sound outlet channel 31 can be rotated and slid at the inlet side, outlet side or middle of the earpiece sound outlet channel 31, the valve 51 of the speaker sound outlet channel 32 can be rotated and slid at the inlet side, outlet side or middle of the speaker sound outlet channel 32, or the valve 51 of the earpiece sound outlet channel 31 can be rotated and slid at the inlet side, outlet side or middle of the earpiece sound outlet channel 31, and the speaker sound outlet channel 32 can be rotated and slid at the inlet side, outlet side or middle of the earpiece sound outlet channel 31. The valve 51 of the sound channel 32 can be slidably set on the inlet side, outlet side or middle of the speaker sound outlet channel 32, or vice versa, that is, the valve 51 of the earpiece sound outlet channel 31 is slidably set, and the valve 51 of the speaker sound outlet channel 32 is rotated; when there are multiple valves 51 on the earpiece sound outlet channel 31 and the speaker sound outlet channel 32, all the valves 51 on the earpiece sound outlet channel 31 can be rotated, and all the valves 51 on the speaker sound outlet channel 32 can be slid, or vice versa, that is, all the valves 51 on the earpiece sound outlet channel 31 can be slid, and all the valves 51 on the speaker sound outlet channel 32 can be rotated, or of the multiple valves 51 of the earpiece sound outlet channel 31, some of the valves 51 can be slid, and some of the valves 51 can be rotated, and the valves 51 on the speaker sound outlet channel 32 can be set similarly. Those skilled in the art will appreciate that, in one embodiment, the arrangement of the plurality of valves 51 on the earpiece sound outlet channel 31 or the speaker sound outlet channel 32 and the positions of the valves 51 on the earpiece sound outlet channel 31 or the speaker sound outlet channel 32 can be freely combined. The above content is exemplary and is not intended to limit the scope of protection of the present disclosure. Any combination or combination of the number, position and arrangement of the valves 51 made by those skilled in the art based on the technical solution of the present disclosure is within the scope of protection of the present disclosure.

[0042] When the valve 51 is rotated, the axis of rotation can be arranged along the axis of the sound outlet channel 30 or radially perpendicular to the axis of the sound outlet channel 30. When the valve 51 is pushed or pulled, it can be pushed in from the left side of the sound outlet channel 30, the right side of the sound outlet channel 30, the top side of the sound outlet channel 30, or the bottom side of the sound outlet channel 30. The terms "left," "right," "top," and "bottom" are relative positions, with the left side being opposite the right side, and the top being opposite the bottom. It should be understood that the terms "left," "right," "top," and "bottom" are used to describe various information, but should not be limited to these terms. These terms are merely used to distinguish between positions in the sound outlet channel 30 and do not indicate a specific order or importance. In fact, the terms "left," "right," "top," and "bottom" are fully interchangeable. For example, the left side can also be referred to as the right side, and similarly, the top side can also be referred to as the bottom side, without departing from the scope of this disclosure.

[0043] In this embodiment, there are multiple options for setting the position of the valve 51 in the earpiece sound outlet channel 31 and the speaker sound outlet channel 32. When one of the positions of the sound outlet channel 30 cannot be set due to restrictions on the design requirements of other parts, multiple position options can ensure that the function of the valve 51 to close the earpiece sound outlet channel 31 or the speaker sound outlet channel 32 is not affected. In addition, the valve 51 can be flexibly set according to the complex and narrow space inside the terminal device, reducing the internal storage space of the terminal device and meeting the user's pursuit of a thin and light terminal design.

[0044] In one embodiment, valve 51 can be made of either metal or magnetic material. The driving component includes an electromagnetic pole 52. When energized, electromagnetic pole 52 generates a magnetic force to drive the metal valve 51. The term "magnetic material" refers to the valve 51 being a metallic magnetic material, a magnet, or a non-metallic magnetic material that responds to a magnetic field in some manner. The driving component, electromagnetic pole 52, generates a magnetic force when energized, which attracts valve 51 and drives its movement. The movement of valve 51 can be either flipping or rotating, where the flipping or rotating configuration is coupled with a rotating shaft, or sliding or pushing and pulling, where the sliding or pushing and pulling configuration is coupled with a slide rail or a slide slot. In this embodiment, the valve 51 is made of a magnetic material, and the driving component includes an electromagnetic pole 52. In an electronic terminal device, the characteristics of the terminal device, such as electronic power supply, can be utilized to facilitate the generation of magnetic force by energizing electromagnetic pole 52. This reduces the number of components, minimizes the size of the terminal device, and saves space, making the electronic terminal device thinner and lighter, meeting users' demand for thinner and lighter terminal designs.

[0045] In one embodiment, there are two electromagnetic poles 52, including a first electromagnetic pole 521 and a second electromagnetic pole 522, and the magnetic pole surface of the first electromagnetic pole 521 and the magnetic pole surface of the second electromagnetic pole 522 are arranged opposite to each other; the first electromagnetic pole 521 is arranged on the side of the earpiece sound outlet channel 31 and away from the speaker sound outlet channel 32, and the second electromagnetic pole 522 is arranged on the side of the speaker sound outlet channel 32 and away from the earpiece sound outlet channel 31; the first electromagnetic pole 521 or the second electromagnetic pole 522 is energized to generate magnetic force to drive the movement of the valve 51.

[0046] This embodiment is one of all the embodiments. Specifically, there are two electromagnetic poles 52, 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 or in contact with each other. The magnetic pole surface of the first electromagnetic pole 521 is 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 and the magnetic pole surface of the second electromagnetic pole 522 are face to face. The first electromagnetic pole 521 is arranged on the side of the earpiece sound outlet channel 31 and away from the speaker sound outlet channel 32, and the second electromagnetic pole 522 is arranged on the side of the speaker sound outlet channel 32 and away from the earpiece sound outlet channel. on one side of the channel 31; specifically, because the earpiece sound output channel 31 and the speaker sound output channel 32 are independent of each other and are separated by a certain distance, the earpiece sound output channel 31 includes a side close to the speaker sound output channel 32 and a side away from the speaker sound output channel 32; the same is true for the speaker sound output channel 32; in this embodiment, the first electromagnetic pole 521 is arranged at the earpiece sound output channel 31 and is away from the side of the speaker sound output channel 32, and the second electromagnetic pole 522 is arranged at the speaker sound output channel 32 and is away from the side of the earpiece sound output channel 31, so that the first electromagnetic pole 521 and the second electromagnetic pole 522 are separated by a certain distance and do not interfere with each other.

[0047] Furthermore, in this embodiment, the first electromagnetic pole 521 or the second electromagnetic pole 522 can be alternately energized to generate magnetic force. Alternating energization means that the first electromagnetic pole 521 and the second electromagnetic pole 522 are not energized at the same time. Alternatively, the first electromagnetic pole 521 is energized while the second electromagnetic pole 522 is de-energized; or the first electromagnetic pole 521 is de-energized while the second electromagnetic pole 522 is energized. In this case, in one embodiment, there is only one valve 51 , wherein the valve 51 is driven by the driving component to move between the earpiece sound output channel 31 and the speaker sound output channel 32 . In another embodiment, there are two valves 51 , including a first valve 51 and a second valve 51 ; wherein the first valve 51 is used to cut off the earpiece sound output channel 31, and the second valve 51 is used to cut off the speaker sound output channel 32.

[0048] In this embodiment, the valve 51 has one and is located between the earpiece sound outlet channel 31 and the speaker sound outlet channel 32. When the speaker mode needs to be realized, the first electromagnetic pole 521 is energized and the second electromagnetic pole 522 is de-energized. The first electromagnetic pole 521 generates a magnetic force and attracts the valve 51 to move toward the first electromagnetic pole 521. Since the first electromagnetic pole 521 is arranged close to the earpiece sound outlet channel 31, when the valve 51 moves toward the earpiece sound outlet channel 31, the earpiece sound outlet channel 31 is closed, and the second electromagnetic pole 522 is de-energized and does not generate a magnetic force, and cannot attract the valve 51. Therefore, the speaker sound outlet channel 32 is opened and connected to the sound cavity 40, and the sound generated by the earpiece speaker 20 is output from the speaker sound outlet channel 32, realizing the speaker mode; when it is necessary to switch to the earpiece mode, the first electromagnetic pole 521 is switched on. And the second electromagnetic pole 522 is energized, therefore, the first electromagnetic pole 521 is switched off and the second electromagnetic pole 522 is energized, the second electromagnetic pole 522 generates magnetic force and attracts the valve 51 to move in the direction of the second electromagnetic pole 522. Since the second electromagnetic pole 522 is arranged close to the speaker sound outlet channel 32, the valve 51 moves from the original earpiece sound outlet channel 31 to the direction of the speaker sound outlet channel 32, and finally closes the speaker sound outlet channel 32. At this time, the first electromagnetic pole 521 is powered off and cannot generate magnetic force. The first electromagnetic pole 521 cannot attract the valve 51, and the valve 51 is now attracted to the speaker sound outlet channel 32 by the second electromagnetic pole 522. Therefore, the earpiece sound outlet channel 31 is opened and connected to the sound cavity 40, and the sound generated by the earpiece speaker 20 is output from the earpiece sound outlet channel 31, realizing the earpiece mode.

[0049] It can be seen from the above technical solution that the valve 51 has one, and the working principle of switching the earpiece mode and the speaker mode between the valve 51 and the two electromagnetic poles 52 is explained, but in other technical solutions, the sound output channel 30 may also have two or more valves 51; and no matter whether the valve 51 has one, two or more, the valve 51 can be a rotation or flip movement, or a push-pull or sliding movement; when the valve 51 has one, if it is a rotation (flip) or sliding (push-pull) movement, the valve 51 rotates or slides in the direction of the first electromagnetic pole 521 when the first electromagnetic pole 521 is energized, thereby closing the earpiece sound output channel 31 and realizing the speaker mode; the valve 51 rotates or slides in the direction of the second electromagnetic pole 522 when the second electromagnetic pole 522 is energized, thereby closing the speaker sound output channel 32 and realizing the earpiece mode. When there are two valves 51, they include a first valve 51 and a second valve 51. The first valve 51 is positioned near the receiver sound outlet channel 31 to close the receiver sound outlet channel 31, and the second valve 51 is positioned near the speaker sound outlet channel 32 to close the speaker sound outlet channel 32. The first valve 51 and the second valve 51 can also rotate or flip, or push, pull, or slide. If the valve 51 rotates (flips) or slides (push and pull), when the first electromagnetic pole 521 is energized, the first valve 51 rotates or slides toward the first electromagnetic pole 521, thereby closing or opening the receiver sound outlet channel 31. When the second electromagnetic pole 522 is energized, the second valve 51 rotates or slides toward the second electromagnetic pole 522, thereby closing or opening the speaker sound outlet channel 32.

[0050] In one embodiment, the switching assembly 50 further includes one or more rotating shafts 53; the valve 51 is mounted on the rotating shafts 53 and is rotatable about the rotating shafts 53. In one embodiment, the extension direction of the earpiece sound output channel 31 is parallel to the extension direction of the speaker sound output channel 32; and the axis of the rotating shaft 53 is perpendicular or parallel to the extension direction of the sound output channel 30.

[0051] The switching assembly 50 includes a rotating shaft 53, which is used to mount a valve 51, allowing the valve 51 to rotate about the rotating shaft 53. Therefore, the switching assembly 50 including the rotating shaft 53 corresponds to a technical solution in which the valve 51 can rotate. Specifically, when there is a single rotating shaft 53, one or two valves 51 can be mounted on the rotating shaft 53. When there are multiple rotating shafts 53, one or two valves 51 can be mounted on each rotating shaft 53. The rotating shafts 53 and valves 51 can be located at the entrance, exit, or center of the sound output channel 30. At least one rotating shaft 53 and at least one valve 51 can be provided on the earpiece sound output channel 31 or the speaker sound output channel 32. The extension direction of the earpiece sound outlet channel 31 is parallel to the extension direction of the speaker sound outlet channel 32, and 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 located 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 bottom of the earpiece sound outlet channel 31 to the speaker sound outlet channel 32, or from the top of the earpiece sound outlet channel 31 to the speaker sound outlet channel 32, where "above" and "below" are relative positions used to distinguish the description of positions. In fact, expressions such as "above" and "below" can be used interchangeably. For example, without departing from the scope of this disclosure, above can also be referred to as below, and similarly, below can also be referred to as above.

[0052] When the axis of the rotating shaft 53 is perpendicular to the axis of the sound output channel 30, the valve 51 is parallel to the radial cross-section of the sound output channel 30 when closing the earpiece sound output channel 31 or closing the speaker sound output channel 32. However, when switching and rotating between the earpiece sound output channel 31 and the speaker sound output channel 32, the valve 51 has an angle with the radial cross-section of the sound output channel 30.

[0053] There are two electromagnetic poles 52, which control the valve 51 to close the earpiece sound outlet channel 31 or the speaker sound outlet channel 32 by switching on the power. At this time, the valve 51 has one or two, or multiple valves. The number and position settings of the valves 51 can be selected according to design requirements, and the number, position and position relationship of the rotating shaft 53 with the axis of the sound outlet channel 30 can also be selected according to design requirements. It can be seen that the number and position of the valves 51 and the rotating shaft 53 can be flexibly selected and combined. When one of the positions of the sound outlet channel 30 cannot be set due to restrictions on the design requirements of other parts, multiple position selections or quantity selections still do not affect the function of the valve 51 to close the earpiece sound outlet channel 31 or the speaker sound outlet channel 32. In addition, the selection of the valve 51 and the rotating shaft 53 can be flexibly set according to the complex and narrow space inside the terminal device, which is used to reduce the internal storage space of the terminal device and meet the user's pursuit of light and thin terminal design.

[0054] The technical solution of the present disclosure will be described below through specific embodiments. In particular, a technical solution in which the valve 51 is a magnetic valve 51 and the driving component is an electromagnetic pole 52 is selected. The technical solution is classified according to the number of valves 51 and described in detail using three specific embodiments as follows:

[0055] Embodiment 1: The valve 51 is a magnetic valve 51 and has one; the electromagnetic poles 52 have two, including a first electromagnetic pole 521 and a second electromagnetic pole 522, and the magnetic pole surface of the first electromagnetic pole 521 and the magnetic pole surface of the second electromagnetic pole 522 are arranged opposite to each other; the first electromagnetic pole 521 is arranged on the side of the earpiece sound outlet channel 31 and away from the speaker sound outlet channel 32, and the second electromagnetic pole 522 is arranged on the side of the speaker sound outlet channel 32 and away from the earpiece sound outlet channel 31; the first electromagnetic pole 521 and the second electromagnetic pole 522 are alternately energized to generate magnetic force.

[0056] When the valve 51 is for rotational movement, it should also include a rotating shaft 53 for supporting the rotation of the valve 51, such as Figure 1 and Figure 2 As shown, the shaft 53 has one, and the shaft 53 is arranged on the housing 10 between the earpiece sound outlet channel 31 and the speaker sound outlet channel 32; the valve 51 is installed on the shaft 53 and can rotate around the shaft 53; the first electromagnetic pole 521 is energized, and the second electromagnetic pole 522 is de-energized. After the first electromagnetic pole 521 is energized, a magnetic force is generated to attract the valve 51. Under the action of the magnetic force, the valve 51 rotates around the shaft 53 toward the first electromagnetic pole 521, and then the valve 51 closes the earpiece sound outlet channel 31. At this time, there is no valve 51 in the speaker sound outlet channel 32, so the speaker sound outlet channel 32 is opened and connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the speaker sound outlet channel 32, realizing the speaker function (such as Figure 1 As shown); thereafter, the first electromagnetic pole 521 is powered off and the second electromagnetic pole 522 is powered on. After the first electromagnetic pole 521 is powered off, the magnetic force disappears and the valve 51 cannot be attracted. After the second electromagnetic pole 522 is powered on, a magnetic force is generated to attract the valve 51. Under the action of the magnetic force, the valve 51 rotates from the first electromagnetic pole 521 to the second electromagnetic pole 522 around the rotating shaft 53. When the valve 51 touches the speaker sound output channel 32, the channel structure of the speaker sound output channel 32 or the baffle structure on the rotating shaft 53 prevents the valve 51 from continuing to rotate, and then the valve 51 closes the speaker sound output channel 32. At this time, there is no valve 51 in the earpiece sound output channel 31, so the earpiece sound output channel 31 is opened and connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the earpiece sound output channel 31, realizing the earpiece function (as shown in FIG. Figure 2 shown).

[0057] When the valve 51 is sliding, it should also include a slide rail or groove for supporting the sliding of the valve 51, and the slide rail has one, the slide rail extends along the radial direction of the sound outlet channel 30, and the length of the slide rail is the same as the radial length of the sound outlet channel 30; the valve 51 is installed on the slide rail and slides along the slide rail; the first electromagnetic pole 521 is energized, and the second electromagnetic pole 522 is de-energized. After the first electromagnetic pole 521 is energized, a magnetic force is generated to attract the valve 51. Under the action of the magnetic force, the valve 51 slides along the slide rail toward the first electromagnetic pole 521. When the valve 51 can completely cover and close the earpiece sound outlet channel 31, the baffle structure on the slide rail prevents the valve 51 from continuing to slide, and then the valve 51 stops sliding and closes the earpiece sound outlet channel 31. At this time, there is no valve 51 in the speaker sound outlet channel 32, so the speaker sound outlet channel 32 is open and connected to the sound cavity 40, and the earpiece speaker 20 The sound emitted is emitted from the speaker sound output channel 32, realizing the speaker function; thereafter, the first electromagnetic pole 521 is powered off and the second electromagnetic pole 522 is powered on. After the first electromagnetic pole 521 is powered off, the magnetic force disappears and the valve 51 cannot be attracted. After the second electromagnetic pole 522 is powered on, a magnetic force is generated to attract the valve 51. Under the action of the magnetic force, the valve 51 slides from the first electromagnetic pole 521 to the second electromagnetic pole 522 along the slide rail and rotates. When the valve 51 touches the speaker sound output channel 32, the channel structure of the speaker sound output channel 32 or the baffle structure on the rotating shaft 53 prevents the valve 51 from continuing to rotate, and then the valve 51 closes the speaker sound output channel 32. At this time, there is no valve 51 in the earpiece sound output channel 31, so the earpiece sound output channel 31 is opened and connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the earpiece sound output channel 31, realizing the earpiece function.

[0058] In the first embodiment, when the rotating shaft 53 is perpendicular to the axis of the sound output channel 30, the valve 51 and the rotating shaft 53 can be located at the inlet and outlet sides of the sound output channel 30. When the rotating shaft 53 is parallel to the axis of the sound output channel 30, the valve 51 and the rotating shaft 53 can be located at the inlet, outlet, and center of the sound output channel 30. When the valve 51 slides, the slide rail can be located at the inlet, outlet, and center of the sound output channel 30.

[0059] In addition, it should be noted that because the valve 51 has a single door, when the valve 51 rotates, whether the rotating shaft 53 is parallel to or perpendicular to the axis of the sound output channel 30, the valve 51 can be a valve 51 with a single door or a valve 51 with two integrally designed doors, with a fixed angle between the two integrally designed doors. In the first embodiment, the valve 51 is a valve 51 with a single door. When the valve 51 is a valve 51 with two integrally designed doors, the two integrally designed doors are used to close the earpiece sound output channel 31 and the speaker sound output channel 32, respectively. The working principle is the same as that of the valve 51 with a single door, and will not be repeated here. However, the two integrally designed doors can be located not only at the inlet and outlet sides of the sound output channel 30, but also in the middle of the sound output channel 30.

[0060] Embodiment 2: The valve 51 is a magnetic valve 51 and has one; the electromagnetic pole 52 has one.

[0061] When the valve 51 is rotating and the rotating shaft 53 is parallel to the sound outlet channel 30, it should also include a rotating shaft 53 for supporting the rotation of the valve 51, and the rotating shaft 53 has a valve 51 installed on the rotating shaft 53 and can rotate around the rotating shaft 53 to close the speaker sound outlet channel 32; before the electromagnetic pole 52 is energized, the valve 51 is in a normally open state, that is, it cannot close the speaker sound outlet channel 32. After the electromagnetic pole 52 is energized, it generates magnetic force to attract the valve 51. Under the action of the magnetic force, the valve 51 rotates around the rotating shaft 53 toward the electromagnetic pole 52, and the valve 51 The speaker sound outlet channel 32 is closed, and the sound emitted by the earpiece speaker 20 is emitted by the earpiece sound outlet channel 31, realizing the earpiece function; after that, the electromagnetic pole 52 is powered off. After the electromagnetic pole 52 is powered off, the magnetic force disappears and the valve 51 cannot be adsorbed. A reset spring is provided between the rotating shaft 53 and the valve 51. The elastic force of the reset spring pulls the valve 51 to reset, and the speaker sound outlet channel 32 is opened. The sound emitted by the earpiece speaker 20 can be emitted by the speaker sound outlet channel 32, realizing the speaker function. The pulling force of the reset spring is less than the magnetic force generated after the electromagnetic pole 52 is powered on. It should be noted that, before the electromagnetic pole 52 is energized, the valve 51 on the speaker sound output channel 32 can also be normally closed, that is, when the electromagnetic pole 52 is energized, the valve 51 opens the speaker sound output channel 32, and when the electromagnetic pole 52 is de-energized, the valve 51 loses the magnetic attraction of the electromagnetic pole 52, and is reset under the elastic force of the reset spring, closing the speaker sound output channel 32; in addition, the rotating shaft 53 and the electromagnetic pole 52 can be located on the same side of the speaker sound output channel 32, or on both sides of the speaker sound output channel 32. Specifically, when the valve 51 is in the normally closed state, the rotating shaft 53 and the electromagnetic pole 52 can be located at the side of the speaker sound output channel 32 close to the earpiece sound output channel 31, or at the side of the speaker sound output channel 32 away from the earpiece sound output channel 31; when the valve 51 is in the normally open state, one of the rotating shaft 53 or the electromagnetic pole 52 is located at the side of the speaker sound output channel 32 close to the earpiece sound output channel 31, and the other is located at the side of the speaker sound output channel 32 away from the earpiece sound output channel 31. It should be noted that when the rotating shaft 53 is perpendicular to the sound outlet channel 30, the rotating shaft 53 is located on the side of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31, and the electromagnetic pole 52 is located on the side of the speaker sound outlet channel 32 close to the earpiece sound outlet channel 31, and a space for hiding the valve 51 is provided in the shell 10 on the side of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31. When the speaker sound outlet channel 32 is opened, the valve 51 is hidden in the space; the process of the valve 51 closing the speaker sound outlet channel 32 is the same as when the rotating shaft 53 and the sound outlet channel 30 are parallel, and will not be repeated.

[0062] When the valve 51 is sliding, it should also include a slide rail or groove for supporting the sliding of the valve 51, and the slide rail has one, the slide rail extends along the radial direction of the speaker sound outlet channel 32, one end of the slide rail is located in the shell 10 on the side of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31, and the other end of the slide rail is located on the side of the speaker sound outlet channel 32 close to the earpiece sound outlet channel 31, and the length of the slide rail is greater than or equal to the width of the two valves 51; the valve 51 is installed on the slide rail and slides along the slide rail; before the electromagnetic pole 52 is energized, the valve 51 is in a normally open state, the valve 51 is located in the shell 10, and the valve 51 is away from the end of the sound outlet channel 30 A return spring is provided between the electromagnetic pole 52 and the slide rail. When the electromagnetic pole 52 is energized, a magnetic force is generated to attract the valve 51. The valve 51 slides toward the electromagnetic pole 52 along the slide rail under the action of the magnetic force. The valve 51 closes the speaker sound output channel 32, and the sound emitted by the earpiece speaker 20 is emitted from the speaker sound output channel 32, thereby realizing the earpiece function; thereafter, the electromagnetic pole 52 is powered off. After the electromagnetic pole 52 is powered off, the magnetic force disappears and the valve 51 cannot be attracted. The valve 51 is pulled back to the shell 10 along the slide rail by the elastic force of the return spring. At this time, the speaker sound output channel 32 is connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the speaker sound output channel 32, thereby realizing the speaker function. Similarly, before the electromagnetic pole 52 is energized, the valve 51 can also be in the normally closed state. A return spring is provided at one end of the valve 51 close to the earpiece sound outlet channel 31 and the slide rail. When the electromagnetic pole 52 is energized, the valve 51 opens the speaker sound outlet channel 32. When the electromagnetic pole 52 is de-energized, the valve 51 loses the magnetic attraction of the electromagnetic pole 52 and is reset under the elastic force of the return spring, closing the speaker sound outlet channel 32. In addition, before the electromagnetic pole 52 is energized, whether the valve 51 is in the normally open state or the normally closed state, one of the electromagnetic pole 52 and the valve 51 is located on the side of the speaker sound outlet channel 32 close to the earpiece sound outlet channel 31, and the other is located on the side of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31.

[0063] In embodiment two, when the rotating shaft 53 is perpendicular or parallel to the axis of the sound output channel 30, the valve 51 and the rotating shaft 53 can be located at the inlet side, outlet side and middle of the sound output channel 30; when the valve 51 slides, the sliding rail can be located at the inlet side, outlet side and middle of the sound output channel 30.

[0064] Embodiment 3: The valve 51 is a magnetic valve 51 with two valves: a first valve 51 and a second valve 51; the electromagnetic poles 52 have two valves, a third electromagnetic pole 52 and a fourth electromagnetic pole 52; the first valve 51 cooperates with the third electromagnetic pole 52 to close the earpiece sound output channel 31, and the second valve 51 cooperates with the fourth electromagnetic pole 52 to close the speaker sound output channel 32.

[0065] When the valve 51 is rotating and moving, it should also include a rotating shaft 53 for supporting the rotation of the valve 51. When the rotating shaft 53 has one, the rotating shaft 53 is arranged on the housing 10 between the earpiece sound outlet channel 31 and the speaker sound outlet channel 32; the first valve 51 and the second valve 51 are both installed on the rotating shaft 53 and can rotate around the rotating shaft 53, wherein a baffle is provided on the rotating shaft 53 and a return spring is provided between the rotating shaft 53 and the first valve 51, and between the rotating shaft 53 and the second valve 51; before the electromagnetic pole 52 is energized, the first valve 51 and the second valve 51 are in a normally open state, the fourth electromagnetic pole 52 is energized, and the third electromagnetic pole 52 is de-energized. After the fourth electromagnetic pole 52 is energized, a magnetic force is generated to attract the second valve 51, and the second valve 51 rotates around the rotating shaft 53 toward the fourth electromagnetic pole 52 under the action of the magnetic force. The second valve 51 closes the speaker sound outlet channel 32, and the earpiece outputs sound. There is no valve 51 in the channel 31, so the earpiece sound output channel 31 is opened and connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the earpiece sound output channel 31, realizing the earpiece function; then, the third electromagnetic pole 52 is energized and the fourth electromagnetic pole 52 is de-energized. After the third electromagnetic pole 52 is energized, a magnetic force is generated to attract the first valve 51, and the first valve 51 rotates around the rotating shaft 53 toward the third electromagnetic pole 52 under the action of the magnetic force, and then the first valve 51 closes the earpiece sound output channel 31. After the fourth electromagnetic pole 52 is de-energized, no magnetic force is generated, and the second valve 51 is reset under the pulling force of the reset spring. At this time, there is no valve 51 in the speaker sound output channel 32, so the speaker sound output channel 32 is opened and connected to the sound cavity 40, and the sound emitted by the earpiece speaker 20 is emitted from the speaker sound output channel 32, realizing the speaker function; when realizing the speaker function, the third electromagnetic pole 52 can also be de-energized. When there are two rotating shafts 53, including a first rotating shaft and a second rotating shaft, a rotating shaft 53, a valve 51 and an electromagnetic pole 52 are respectively provided on the earpiece sound outlet channel 31 and the speaker sound outlet channel 32. Specifically, the first valve 51 is installed on the first rotating shaft, and the second valve 51 is installed on the second rotating shaft. The third electromagnetic pole 52, the first valve 51 and the first rotating shaft act to close the earpiece sound outlet channel 31, and the fourth electromagnetic pole 52, the second valve 51 and the second rotating shaft act to close the speaker sound outlet channel 32. Its working process is the same as the working principle of the valve 51 in embodiment 2 that is rotational movement, and will not be repeated here.

[0066] When the valve 51 is slidingly moved, it should also include a slide rail or groove for supporting the sliding of the valve 51, and the slide rail can be one or two, the same as when the valve 51 is rotationally moved. When there is one slide rail, the two valves 51 are located on the same slide rail. When there are two slide rails, the two valves 51 are respectively located on slide rails at two corresponding positions. The two electromagnetic poles 52 respectively control the corresponding two valves 51 to slide on the corresponding slide rails, thereby closing the sound output channel 30 at the corresponding position.

[0067] Among them, when there is one slide rail, the slide rail extends radially along the sound outlet channel 30, one end of the slide rail is located in the shell 10 on the side of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31, and the other end of the slide rail is located in the shell 10 on the side of the earpiece sound outlet channel 31 away from the speaker sound outlet channel 32, and the length of the slide rail is greater than or equal to the width of the four valves 51; the two valves 51 are installed on the slide rail and slide along the slide rail. In other words, the first valve 51 only slides on the slide rail located within the range of the earpiece sound outlet channel 31 and the shell 10, and the second valve 51 only slides on the slide rail located within the range of the speaker sound outlet channel 32 and the shell 10; before the electromagnetic pole 52 is energized , the valve 51 is in a normally open state, and the valve 51 is located in the housing 10. The first valve 51 is provided with a return spring between the housing 10 at the end of the earpiece sound outlet channel 31 away from the speaker sound outlet channel 32 and the slide rail. The second valve 51 is provided with a return spring between the housing 10 at the end of the speaker sound outlet channel 32 away from the earpiece sound outlet channel 31 and the slide rail. When the electromagnetic pole 52 is energized, it generates a magnetic force to attract the valve 51, and the valve 51 slides along the slide rail toward the electromagnetic pole 52 under the action of the magnetic force; thereafter, the electromagnetic pole 52 is de-energized, and the magnetic force disappears after the electromagnetic pole 52 is de-energized, and the valve 51 cannot be attracted. The valve 51 is pulled back to the housing 10 along the slide rail under the elastic force of the return spring. Similarly, before the electromagnetic pole 52 is energized, the valve 51 can also be in a normally closed state. The first valve 51 is provided with a return spring between the end of the earpiece sound outlet channel 31 close to the speaker sound outlet channel 32 and the slide rail, and the second valve 51 is provided with a return spring between the end of the speaker sound outlet channel 32 close to the earpiece sound outlet channel 31 and the slide rail. When the electromagnetic pole 52 is energized, the first valve 51 or the second valve 51 slides into the corresponding shell 10 respectively to open the corresponding sound outlet channel 30. When the electromagnetic pole 52 is de-energized, the valve 51 loses the magnetic attraction of the electromagnetic pole 52 and is reset under the elastic force of the return spring to close the corresponding sound outlet channel 30. In addition, before the electromagnetic pole 52 is energized, one of the first valve 51 and the second valve 51 is in a normally closed state and the other is in a normally open state. Those skilled in the art can freely combine them according to design requirements. In addition, before the electromagnetic pole 52 is energized, whether the valve 51 is in the normally open state or the normally closed state, the first valve 51 and the third electromagnetic pole 52 on the earpiece sound output channel 31 are respectively located on both sides of the earpiece sound output channel 31, and the same is true for the speaker sound output channel 32.

[0068] In embodiment three, when there is one rotating shaft 53, the rotating shaft 53 is perpendicular to the axis of the sound output channel 30, and the valve 51 and the rotating shaft 53 can be located at the inlet side and the outlet side of the sound output channel 30. When there are two rotating shafts 53, the rotating shaft 53 is perpendicular or parallel to the axis of the sound output channel 30, and the valve 51 and the rotating shaft 53 can be located at the inlet side, the outlet side and the middle of the sound output channel 30; when the valve 51 slides, the slide rail can be located at the inlet side, the outlet side and the middle of the sound output channel 30.

[0069] Based on the same concept, an embodiment of the present disclosure further provides a terminal device, including the above-mentioned earpiece speaker 20 sound output component.

[0070] The terminal device can be a mobile electronic device such as a mobile phone or a tablet. The terminal device has six sides: front, back, upper side, lower side, left side and right side. The front and back of the terminal device are opposite to each other, the upper side and lower side are opposite to each other, and the left side and right side are opposite to each other. The front of the terminal device is the side with a display screen, that is, the side that can realize human-computer interaction; the earpiece speaker 20 sound output component is located at the upper part of the terminal device, that is, close to the end of the upper side of the terminal device. Since the sound output channel 30 of the earpiece speaker 20 sound output component includes an independent and spaced earpiece sound output channel 31 and a speaker sound output channel 32, the outlet side of the earpiece sound output channel 31 is located on the front of the terminal device, and the outlet side of the speaker sound output channel 32 can be located on the front of the terminal device, but at a certain distance from the outlet side of the earpiece sound output channel 31, or it can be located at any of the upper side, left side or right side of the terminal device.

[0071] The handset speaker 20 in the earpiece speaker 20 sound output component is a two-in-one speaker with both earpiece and speaker functions; the switching component 50 and the independent and spaced earpiece sound output channel 31 and speaker sound output channel 32 on the sound output channel 30 can enable the earpiece speaker 20 to close the speaker sound output channel 32 when the earpiece mode is turned on, so that the sound of the earpiece speaker 20 in the earpiece mode cannot be leaked from the speaker sound output channel 32, ensuring the privacy of the earpiece; when the speaker mode is turned on, the speaker sound output channel 32 is opened; thereby, the earpiece speaker 20 in the speaker mode ensures the intensity and appropriate loudness of the playback volume. In addition, since the lower part of the terminal device, that is, the end close to the lower side of the terminal device, also has a speaker (loudspeaker), when the terminal device is played outward, the earpiece speaker 20 sound output component realizes the speaker mode, and together with the speaker at the bottom of the terminal device, forms a dual sound cavity. The two independent sound cavities make the sound played by the terminal device more three-dimensional, satisfying people's pursuit of high-quality audio and video.

[0072] The structural position of the earpiece speaker 20 sound output component in the terminal device and the specific operation of each component have been described in detail in the above-mentioned embodiments 1, 2, and 3, and will not be elaborated here.

[0073] It is understood that in this disclosure, "plurality" refers to two or more than two, and other quantifiers are similar. "And / or" describes the association relationship of related objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0074] It will be further understood that the terms "first," "second," "third," "fourth," etc. are used to describe various information, but such information should not be limited to these terms. These terms are merely used to distinguish information of the same type from one another and do not indicate a particular order or level of importance. In fact, the expressions "first," "second," "third," "fourth," etc. are completely interchangeable. For example, the first electromagnetic pole 521 may also be referred to as the second electromagnetic pole 522, and similarly, the second shaft may also be referred to as the first shaft without departing from the scope of this disclosure.

[0075] It can be further understood that the terms "center", "longitudinal", "lateral", "front", "back", "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this embodiment and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation.

[0076] It is further understood that, unless otherwise specified, “connection” includes a direct connection where there are no other components between the two elements, and also includes an indirect connection where there are other elements between the two elements.

[0077] It is further understood that although operations are described in a particular order in the drawings in the embodiments of the present disclosure, this should not be construed as requiring that the operations be performed in the particular order shown or in a serial order, or that all of the operations shown be performed to obtain the desired results. In certain circumstances, multitasking and parallel processing may be advantageous.
