[0051] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0052] In the related art, electronic devices such as mobile phones usually include two audio output modes, one is a handset output mode used in a handheld call state, and the other is a loudspeaker output mode in an audio external speaker state. Usually, a hole is opened on the top front of electronic devices such as mobile phones (i.e., the side where the display screen of the electronic device is located) for use as a handset.

[0053] In one example, a speaker unit is set on the top of the electronic device, and when the electronic device outputs audio information in the sound amplification output mode, the speaker unit is used as a sound-emitting device. When the user holds the electronic device for a call, the handset is used to receive the audio information, and the audio information is provided by the speaker unit. In the handset output mode, the audio information needs to be in a low-frequency bandwidth state. However, since the speaker is used as the sound-emitting device in this example, the audio information cannot be kept in a low-frequency bandwidth state in the handset output mode. Therefore, in order to meet the requirement that the audio information output by the electronic device in the handset mode is in a low-frequency bandwidth state, the back cavity of the speaker unit is opened to ensure that the user can talk normally when holding the electronic device. However, opening the back cavity of the speaker unit affects the audio stereo effect of the electronic device in the sound amplification mode, resulting in a weak stereo field, which affects the user's experience.

[0054] In another example, an earpiece unit is set at the top of the electronic device as a sound-emitting device, and a hole is opened on the top front of the electronic device as an earpiece. When a user holds the electronic device for a call, the user receives audio information emitted by the earpiece unit through the earpiece. At the same time, in order to realize the external speaker function, a single speaker is set at the bottom of the electronic device, and a through hole is opened at the bottom of the electronic device. When the audio output mode of the electronic device is amplification mode, the bottom speaker unit outputs audio information to the outside. Since only a single speaker is set at the bottom of the electronic device, a symmetrical stereo field cannot be formed when the audio information is played externally, which reduces the sound quality of the audio information, affects the user's experience, and cannot meet the user's demand for high-quality sound effects.

[0055] The present disclosure proposes an audio output mode adjustment structure, which is applied to an electronic device with a handset mode, wherein the electronic device can be, for example, a mobile phone, a tablet computer, or other electronic device with a call function. The audio output mode adjustment structure includes a sound output channel connecting the inside and outside of the electronic device, the opening of the sound output channel is located on the side of the top of the electronic device, and the mode adjustment structure also includes an adjustment unit, and the adjustment unit moves relative to the sound output channel. When the electronic device outputs audio in a sound amplification mode, the adjustment unit does not cover the sound output channel, and the sound wave propagates in a straight line through the opening of the sound output channel. The speaker on the top of the electronic device can form a symmetrical stereo field with the speaker arranged at the bottom of the electronic device, thereby improving the stereo effect of the audio in the sound amplification mode and meeting the user's demand for high-quality sound quality. When the electronic device outputs audio in a handset mode, the adjustment unit covers the opening of the sound output channel so that the sound wave propagates toward the display screen side of the electronic device through the opening of the sound output channel, and the audio output mode of the electronic device is adjusted to the handset mode.

[0056] In an exemplary embodiment, Figure 1 As shown, an audio output mode adjustment structure includes an audio output channel 2 connecting the interior 11 and the exterior 12 of the electronic device 1, the audio output channel 2 passes through the top 13 of the electronic device 1, and the opening 21 of the audio output channel 2 (refer to Figure 3 The sound outlet channel 2 is located on the side of the top 13 of the electronic device 1. The shape of the opening 21 of the sound outlet channel 2 can be, for example, circular, elliptical or rectangular, and the radial cross-sectional shape of the sound outlet channel 2 can be the same as its opening 21. Of course, it is understandable that the radial cross-sectional shape of the sound outlet channel 2 can also be different from its opening 21. Along the extension direction of the sound outlet channel 2, the sound outlet channel 2 can be a constant diameter channel or a variable diameter channel. For example, along the sound propagation direction, the area of ​​the radial cross-sectional area of ​​the end of the sound outlet channel 2 connected to the inside 11 of the electronic device 1 is A, and the area of ​​the radial cross-sectional area of ​​the end of the sound outlet channel 2 connected to the outside of the electronic device 1 is B, and area A can be smaller than area B. So as to further enhance the sound amplification effect. In this embodiment, in order to further enhance the sound effect of the electronic device 1, the sound outlet channel 2 is not limited to one, and multiple sound outlet channels can be provided, which are set according to actual conditions.

[0057] In this embodiment, refer to Figure 3 As shown, when the electronic device 1 outputs audio in the sound amplification mode, the sound waves propagate along a straight line from the opening 21 of the sound outlet channel 2. For example, along a first direction (refer to Figure 3 The electronic device 1 transmits audio in the Z-axis direction (as shown in the figure), and cooperates with the speaker (not shown in the figure) at the bottom of the electronic device 1. When the electronic device 1 outputs audio in the sound amplification mode, the speakers at the upper and lower ends of the electronic device 1 jointly output audio information to form a symmetrical stereo field, thereby enhancing the stereo effect of the audio, improving the playback sound quality, and enhancing the user experience.

[0058] In this embodiment, if Figure 1 , Figure 3 , Figure 4 As shown, the audio mode adjustment structure also includes an adjustment unit 3, which is used to adjust the audio output mode. When the electronic device 1 is switched to the handset mode, the adjustment unit 3 is used to change the propagation direction of the sound wave at the opening 21 of the sound outlet channel 2, so that the sound wave propagates from the opening 21 of the sound outlet channel 2 toward the display screen side of the electronic device 1. For example, the sound wave propagates along the second direction (refer to Figure 1 The sound waves of the electronic device 1 are propagated in the Y-axis direction as shown in the figure, so that the audio information is output in the receiver mode when the user holds the electronic device 1 for a call. The propagation direction of the sound waves of the electronic device 1 is changed by the adjustment unit 3, and then the audio output mode of the electronic device 1 is adjusted to output the audio information in the loudspeaker mode or the receiver mode according to the user's usage requirements.

[0059] In this embodiment, the sound output channel 2 and the adjustment unit 3 are provided, and by changing the propagation direction of the sound waves at the opening 21 of the sound output channel 2, both the earpiece output mode and the amplified sound output mode can be realized, without separately providing a speaker unit and an earpiece unit, thereby avoiding excessive occupation of the internal space of the electronic device 1. At the same time, a speaker unit is also provided at the bottom of the electronic device 1. In the amplified sound output mode, the speaker unit at the bottom cooperates with the sound output channel 2 to form a stereo sound output effect, thereby improving the user experience.

[0060] In another exemplary embodiment, Figure 4 As shown, the adjustment unit 3 includes an adjustment portion 31 and a connection portion 32 connected to each other. Under the action of external force, the connection portion 32 drives the adjustment portion 31 to move relative to the opening 21 of the sound outlet channel 2 to cover or not cover the opening 21. When the electronic device 1 outputs audio in the sound amplification mode, the adjustment portion 31 does not cover the opening 21 of the sound outlet channel 2, and the sound at the opening 21 propagates in a straight line to the outside of the electronic device 1. When the audio output mode of the electronic device 1 is the earpiece mode, the adjustment portion 31 covers the opening 21 of the sound outlet channel 2, changes the propagation direction of the sound waves at the opening 21, and is used as an earpiece.

[0061] In one example, referring to Figure 2 As shown, the connection part 32 is arranged in the interior 11 of the electronic device 1, and the connection part 32 extends from the interior 11 of the electronic device 1 to the exterior 12 of the electronic device 1, and the adjustment part 31 is arranged on the outside of the side of the top 13 of the electronic device 1. The adjustment part 31 of the adjustment unit 3 is fixedly connected with the connection part 32 at a predetermined angle, and the predetermined angle is, for example, 90°. Under the action of external force, the connection part 32 is extended along the width direction of the electronic device 1 (refer to Figure 2The connecting portion 32 is connected to the electronic device 1 by the adjusting portion 31 and slides along the side of the top 13 of the electronic device 1 relative to the sound outlet channel 2 to cover or not cover the sound outlet channel 2. A slide groove 131 extending along the width direction of the electronic device 1 is provided on the top 13 of the electronic device 1. One end of the connecting portion 32 extends into the slide groove 131 and can slide along the extension direction of the slide groove 131. The other end of the connecting portion 32, which is the end connected to the adjusting portion 31, extends through the slide groove 131 to the outside 12 of the electronic device 1. External force acts on the connecting portion 32, and the adjusting portion 31 is driven by the connecting portion 32 to move between the first end and the second end of the slide groove 131, thereby adjusting the relative position of the adjusting portion 31 and the sound outlet channel 2, thereby covering or not covering the sound outlet channel 2 to change the propagation direction of the sound waves at the opening 21 of the sound outlet channel 2. When the adjusting portion 31 is located at the first end of the slide groove 131 (refer to Figure 2 When the adjusting portion 31 is at the second end of the slide slot 131 ( Figure 2 The adjusting portion 31 covers the opening 21 of the sound output channel 2, and the audio output mode of the electronic device 1 is the receiver mode, which is convenient for the user to hold the electronic device 1 and listen to the audio information.

[0062] In another exemplary embodiment, Figure 1 , Figure 3 , Figure 4 As shown, the adjustment part 31 is rotatably connected to the connection part 32. When the electronic device 1 outputs audio in the sound amplification mode, the adjustment part 31 and the connection part 32 are located in the interior 11 of the electronic device 1, and the adjustment part 31 does not cover the opening 21 of the sound output channel 2. When the audio output mode of the electronic device 1 is the handset mode, the connection part 32 drives the adjustment part 31 to extend to the exterior 12 of the electronic device 1. For example, a movable channel 132 is provided at the top 13 of the electronic device 1 to connect the interior 11 and the exterior 12 of the electronic device 1. The movable channel 132 extends along the width direction of the electronic device 1 (refer to Figure 3 The connecting portion 32 drives the adjusting portion 31 to extend to the outside 12 of the electronic device 1 through the moving channel 132, and the adjusting portion 31 is flipped relative to the connecting portion 32 to cover the opening 21 of the sound outlet channel 2, switching the audio output mode of the electronic device 1 to the handset mode, so that the user can hold the electronic device 1 for a call.

[0063] In another exemplary embodiment, Figure 3 , Figure 4As shown, the adjustment unit 3 also includes a rotation adjustment portion 33, which can be, for example, a torsion spring or a spring. The adjustment portion 31 and the connection portion 32 can be, for example, rectangular plates, and the adjustment portion 31 is rotationally connected to the connection portion 32 through the rotation adjustment portion 33. The rotation adjustment portion 33 is used to apply a flipping force on the adjustment portion 31 to drive the adjustment portion 31 to flip a preset angle relative to the connection portion 32. When the connection portion 32 drives the adjustment portion 31 to extend to the outside 12 of the electronic device 1 through the moving channel 132 that runs through the top 13 of the electronic device 1, the external force originally acting on the rotation adjustment portion 33 disappears, and the rotation adjustment portion 33 drives the adjustment portion 31 to flip relative to the connection portion 32 under the action of its own restoring force (i.e., the action of the torsion spring or spring to restore to a free state), and the adjustment portion 31 and the connection portion 32 form a preset angle, and the adjustment portion 31 covers the opening 21 of the sound outlet channel 2. The preset angle can be, for example, 90°, 85°, etc. Since the adjustment part 31 covers the opening 21 of the sound output channel 2, the sound waves at the opening 21 of the sound output channel 2 are covered by the adjustment part 31, and the propagation direction is changed, and the sound is output forward along the display screen side of the electronic device 1. At this time, the sound output channel 2 and the adjustment part 31 together form an earpiece, which is convenient for the user to receive audio information when holding the electronic device 1.

[0064] When the connecting portion 32 drives the adjusting portion 31 to move toward the interior 11 of the electronic device 1, the side wall of the moving channel 132 acts on the rotating adjusting portion 33, and there is an interaction force between the two. Under the action of the interaction force, the rotating adjusting portion 33 drives the adjusting portion 31 to flip relative to the connecting portion 32, and the adjusting portion 31 and the connecting portion 32 form a preset angle. Among them, the preset angle at this time is 180°. The adjusting portion 31 moves along the moving channel 132 until the adjusting portion 31 is hidden in the interior 11 of the electronic device 1. At this time, the adjusting portion 31 does not cover the opening 21 of the sound output channel 2. Since the adjusting portion 31 does not cover the opening 21 of the sound output channel 2, the sound waves at the opening 21 of the sound output channel 2 are no longer covered by the adjusting portion 31, and propagate along a straight line from the opening 21 of the sound output channel 2. At this time, when the electronic device outputs audio in the sound amplification output mode, the sound output channel 2 and the speaker arranged at the bottom of the electronic device 1 output sound together to form a stereo sound output effect.

[0065] In another exemplary embodiment, Figure 1 As shown, the audio output mode adjustment structure also includes a driving component 4 and a driving controller 5. The driving component 4 may be, for example, an electric cylinder (not shown in the figure), and the driving controller 5 is used to control the operation of the electric cylinder, and the driving controller 5 is electrically connected to the control unit (not shown in the figure) of the electronic device 1. The piston end of the electric cylinder is connected to the connecting portion 32, and the piston end makes a linear motion in the cylinder body of the electric cylinder, driving the connecting portion 32 to move, adjusting the position of the adjusting portion 31 connected to the connecting portion 32, so as to cover or not cover the sound output channel 2.

[0066] In one example, referring to Figure 2 As shown, the adjusting portion 31 of the adjusting unit 3 is fixedly connected to the connecting portion 32, the connecting portion 32 is arranged in the interior 11 of the electronic device 1, and the adjusting portion 31 is arranged on the outside of the side of the top 13 of the electronic device 1. The adjusting portion 31 can slide along the slide groove 131 provided on the top 13 of the electronic device 1, and the slide groove 131 passes through the top 13 of the electronic device 1. One end of the connecting portion 32 passes through the slide groove 131 and is connected to the adjusting portion 31, and the other end of the connecting portion 32 is fixedly connected to the piston end of the electric cylinder (not shown in the figure). The connecting portion 32 is driven by the piston end of the electric cylinder to move between the first end and the second end of the slide groove 131, thereby adjusting the relative position of the adjusting portion 31 and the sound outlet channel 2.

[0067] In another example, referring to Figure 3 As shown, the adjustment part 31 of the adjustment unit 3 is rotatably connected to one end of the connection part 32, and the other end of the connection part 32 is fixedly connected to the piston end of the electric cylinder. When the electronic device 1 outputs audio in the sound amplification mode, the adjustment part 31 and the connection part 32 are located in the interior 11 of the electronic device 1. When it is necessary to switch the audio output mode of the electronic device 1 to the handset mode, under the action of the electric cylinder (not shown in the figure), the adjustment part 31 is driven by the connection part 32 to extend to the outside 12 of the electronic device 1 through the movable channel 132, and the adjustment part 31 is flipped relative to the connection part 32 to cover the opening 21 of the sound output channel 2. At this time, the sound waves at the opening 21 of the sound output channel 21 are covered by the adjustment part 31, and the propagation direction is changed, and the sound is output in the positive direction along the display screen side of the electronic device 1.

[0068] In another exemplary embodiment, Figure 4 As shown, the drive assembly 4 includes a torque output unit 41 and a transmission unit 42 connected to the torque output unit 41, and the transmission unit 42 is fixedly connected to the connection portion 32. The torque output unit 41 outputs torque to drive the transmission unit 42 to move along the first direction of the electronic device (refer to Figure 3 The Z-axis direction shown in the figure makes a linear motion.

[0069] In one example, referring to Figure 7 As shown, the torque output unit 41 may include, for example, a motor 411 and a gear 413 fixedly connected to the output shaft of the motor 411, and the motor 411 is driven by a drive controller 5 disposed inside the electronic device 1. The transmission unit 42 includes a rack 423, the gear 413 meshes with the rack 423, and the rack 423 is fixedly connected to the connecting portion 32. Under the driving force output by the motor 411, the gear 413 drives the rack 423 to move, thereby driving the connecting portion 32 along the first direction (refer to Figure 3The adjusting portion 31 connected to the connecting portion 32 moves toward the outside 12 of the electronic device 1 .

[0070] In another example, referring to Figure 6 As shown, the torque output unit 41 may include, for example, a motor 411 and a screw 412 connected to the output shaft of the motor 411. The motor 411 is electrically connected to the drive controller 5 disposed inside the electronic device 11, and the transmission unit 42 is threadedly connected to the screw 412. The screw 412 rotates to drive the transmission unit 42 along the first direction (refer to Figure 3 The Z-axis direction shown in the figure makes a linear motion.

[0071] Among them, still refer to Figure 6 As shown, the transmission unit 42 includes a first connection part 421 and a transmission part 422. One end of the first connection part 421 is fixedly connected to the connection part 32, and the other end of the first connection part 421 is fixedly connected to the transmission part 422, and the transmission part 422 is threadedly connected to the screw 412. Under the driving force output by the motor 411, the transmission part 422 is driven to move by the screw 412, and the first connection part 421 and the transmission part 422 move synchronously. The connection part 32 drives the adjustment part 31 to move toward the outside 12 or the inside 11 of the electronic device 1 through the first connection part 421. When the adjustment part 31 is located in the inside 11 of the electronic device 1, the audio output mode of the electronic device 1 is the amplification mode. When the adjustment part 31 is located in the outside 12 of the electronic device 1, the adjustment part 31 covers the opening 21 of the sound outlet channel 2, changes the propagation direction of the sound waves at the opening 21 of the sound outlet channel 2, and the audio output mode of the electronic device 1 is the handset mode.
