In this way, the user is enabled to use the mobile terminal 1 through the display 20 of the first side 11 or the display 20 of the second side 12.

In the embodiment of the present invention, only one receiver 50 is disposed inside the mobile terminal 1, and the receiver 50 plays sound to the outside of the mobile terminal 1 through the main channel 303, the first channel 301, and the second channel 302 which are mutually conducted. It should be noted that, an adjusting mechanism 40 is disposed in the sound guiding channel of the mobile terminal 1, the adjusting mechanism 40 can connect the main channel 303 and the first channel 301 to close the second channel 302, at this time, the receiver 50 can only transmit sound to one side of the first surface 11 of the mobile terminal 1 through the main channel 303 and the first channel 301, the second channel 302 is in a closed state, and the second sound outlet 102 of the second surface 12 does not play sound; alternatively, the adjusting mechanism 40 can conduct the main channel 303 and the second channel 302 to close the first channel 301, and at this time, the receiver 50 can only transmit sound to the side of the second surface 12 of the mobile terminal 1 through the main channel 303 and the second channel 302, and the first sound outlet 101 of the first surface 11 does not emit sound.

In the same principle, if the second infrared sensor on the second side 12 detects that the head of the user approaches, the adjusting mechanism 40 can correspondingly conduct the main channel 303 and the second channel 302 to close the first channel 301.

According to the technical scheme provided by the embodiment of the invention, through the setting of the adjusting mechanism 40, the sound transmission path of the telephone receiver 50 can be determined according to which side of the double-sided screen mobile terminal 1 is currently used by a user, and further, when the user turns over the mobile terminal 1 in the conversation process, the sound transmission path of the telephone receiver 50 can be correspondingly changed, so that the control of the sound generating unit of the mobile terminal 1 is more intelligent. Also, the provision of one receiver 50 reduces the hardware cost of the mobile terminal 1.

The rotating shaft 401 is located at the intersection of the axis of the first channel 301, the axis of the second channel 302 and the axis of the main channel 303. The rotating shaft 401 may be connected to a driving device 403 disposed in the mobile terminal 1 through a connector, or the driving device 403 may also be disposed in the sound guide channel, the driving device 403 is connected to a tube wall of the first channel 301 or the second channel 302 through a connector, the driving device 403 is connected to a processor of the mobile terminal 1, and the driving device 403 may be a motor.

It should be noted that the rotating shaft 401 is connected to the middle of the baffle 402, so that the first end of the baffle 402 slides on the pipe wall of the first channel 301 and the pipe wall of the second channel 302, the second end of the baffle 402, which is far away from the first end, moves in the main channel 303, and when the second end abuts against the connection between the pipe wall of the main channel 303 and the pipe wall of the second channel 302, the main channel 303 is communicated with the first channel 301, the first channel 301 is opened, and the second channel 302 is blocked by the baffle 402 and is closed; when the second end abuts against the connection position of the pipe wall of the main channel 303 and the pipe wall of the first channel 301, the main channel 303 is communicated with the second channel 302, the second channel 302 is opened, and the first channel 301 is blocked by the baffle 402 and is closed. Thus, the sound propagation path of receiver 50 is adjusted by rotating shaft 401 and shutter 402.

Referring to fig. 6, the pipe diameter R1 of the first channel 301 is consistent with the pipe diameter R2 of the second channel 302, and the pipe diameter R3 of the main channel 303 is greater than the pipe diameter R1 of the first channel 301; the axis of the main channel 303 is located on the symmetry plane of the first face 11 and the second face 12. With the arrangement, the main channel 303 is disposed in the middle of the mobile terminal 1, the distance from the axis of the main channel 303 to the first surface 11 is equal to the distance from the axis of the main channel 303 to the second surface 12, that is, L1 is equal to L2, and the receiver is disposed in the middle of the mobile terminal 1, that is, L3 is equal to L4, so that the distance from the receiver 50 to the first surface 11 is equal to the distance from the receiver to the second surface 12, and the pipe diameter R1 of the first channel 301 is equal to the pipe diameter R2 of the second channel 302, thereby ensuring the uniformity of sound propagation of the receiver 50, and ensuring that the audio effects heard by the user on the first surface 11 and the second surface 12 of the mobile terminal 1 are the same.

Referring to fig. 8 to 11, in another embodiment of the present invention, the rotating shaft 401 is located on an axial line of the main channel 303, the rotating shaft 401 is disposed at a connection position of a pipe wall of the first channel 301 and a pipe wall of the second channel 302, and the rotating shaft 401 is connected to one end of the baffle 402. It will be appreciated that rotation of the shaft 401 causes rotation of the flap 402. When one end of the baffle 402, which is far away from the rotating shaft 401, moves to a connecting position of the pipe wall of the abutting main channel 303 and the pipe wall of the second channel 302, the main channel 303 is communicated with the first channel 301, the first channel 301 is opened, and the second channel 302 is blocked by the baffle 402 and is closed; when one end of the baffle 402, which is far away from the pair of the rotating shafts 401, abuts against the connection position of the pipe wall of the main channel 303 and the pipe wall of the first channel 301, the main channel 303 is communicated with the second channel 302, the second channel 302 is opened, and the first channel 301 is blocked by the baffle 402 and is closed. Thus, the sound propagation path of receiver 50 is adjusted by rotating shaft 401 and shutter 402.

Referring to fig. 11, the pipe diameter R1 of the first channel 301 is consistent with the pipe diameter R2 of the second channel 302, and the pipe diameter R3 of the main channel 303 is greater than the pipe diameter R1 of the first channel 301; the axis of the main channel 303 is located on the plane where the axis of the mobile terminal 1 is located, that is, L1-L2. In addition, the receiver is disposed in the middle of the mobile terminal 1, that is, L3 is equal to L4, so that the uniformity of sound propagation of the receiver 50 is ensured, and the audio effect heard by the user on the first side 11 and the second side 12 of the mobile terminal 1 is ensured to be the same.

Referring to fig. 12 to 14, the adjusting mechanism 40 includes a first movable structure 404 disposed in the first channel 301, a second movable structure 405 disposed in the second channel 302, and a control device (not shown), wherein the first movable structure 404 and the second movable structure 405 are both connected to the control device; the control device can control the first movable structure 404 and the second movable structure 405 to be linked, so that the first movable structure 404 opens the first channel 301 and the second movable structure 405 closes the second channel 302, or so that the second movable structure 405 opens the second channel 302 and the first movable structure 404 closes the first channel 301. In particular, the control means is connected to a processor of the mobile terminal 1, which is capable of delivering control signals to the control means to cause said control means to control the movement of the first 404 and second 405 mobile structures.

The first movable structure 404 may include a first rotating shaft and a first baffle, and the second movable structure 405 may include a second rotating shaft and a second baffle, both of which are connected to the control device. The rotation of the first rotating shaft can drive the rotation of the first baffle plate to open or close the first channel 301, and the rotation of the second rotating shaft can drive the second baffle plate to rotate to open or close the second channel 302. When the first channel 301 is in an open state, the second channel 302 is in a closed state; when the first passage 301 is in the closed state, the second passage 302 is in the open state.

Referring to fig. 13 and 14, the first movable structure 404 includes a first dust-proof net 4041 and a first movable plate, the first dust-proof net 4041 and the first movable plate are both connected to the control device, and the first dust-proof net 4041 and the first movable plate are in a linkage relationship; the second movable structure 405 includes a second dust screen 4051 and a second movable plate, the second dust screen 4051 and the second movable plate are both connected to the control device, and the second dust screen 4051 and the second movable plate are in a linkage relationship.

Specifically, the first dust screen 4041 and the first movable plate are linked, and when the first movable plate moves to open the first channel 301, the first dust screen 4041 also moves to open the first channel 301; the first dust screen 4041 and the first movable plate may move up and down to open or close the first passage 301, or may rotate to open or close the first passage 301. On the same principle, when the second movable plate moves to open the second channel 302, the second dust screen 4051 also moves to open the second channel 302; the second dust screen 4051 and the second movable plate may move up and down to open or close the second channel 302, or may rotate to open or close the second channel 302.

Or, when the first movable plate moves to open the first channel 301, the first dust screen 4041 moves to close the first channel 301, and the first dust screen 4041 can pass through sound and block dust and the like; when the first movable plate moves to close the first passage 301, the first dust-proof net 4041 moves to open the first passage 301, and the first movable plate plays a role in blocking sound transmission and preventing dust. On the same principle, when the second movable plate moves to open the second channel 302, the second dust screen 4051 moves to close the second channel 302; when the second movable plate moves to close the second channel 302, the second dust screen 4051 moves to open the second channel 302.

In other embodiments, the first dust-proof net 4041 and the second dust-proof net 4051 may be fixed structures, and the control device is connected to the first movable plate and the second movable plate to control the movement of the first movable plate and the second movable plate. For example, when the second movable plate closes the second channel 302 and the first movable plate moves to open the first channel 301, the sound of the receiver 50 can be transmitted to the first surface 11 through the first dust-proof net 4041. In this way, by providing the first dust-proof net 4041 and the second dust-proof net 4051, dust and the like can be prevented from entering the main passage 303, and the sound quality of the receiver 50 can be ensured more favorably.

Referring to fig. 3, 8 and 12, the mobile terminal 1 further includes a third dust-proof net 60, and the third dust-proof net 60 is disposed on a side of the receiver 50 facing the main channel 303. The third dust prevention net 60 is disposed on a side of the receiver 50 facing the main channel 303, so as to block dust entering the main channel 303, prevent the dust from entering the receiver 50 and affecting the receiver 50, and ensure the quality of sound played by the receiver 50. The sealing structure can be made of foam, the foam is lighter in weight, and the overall quality of the mobile terminal 1 is reduced.

Optionally, the mobile terminal 1 further includes a sealing structure 70, and the sealing structure 70 is embedded between the receiver 50 and a pipe wall of the mobile terminal 1 forming the main channel 303; the sealing structure 70 includes a through hole for receiving the third dust prevention net 60, and the through hole communicates with the main passage 303. The sealing structure 70 can block sound, ensure that sound played by the receiver 50 can be conducted through the main channel 303, prevent sound from leaking, and ensure the quality of sound played by the receiver 50 of the mobile terminal 1.

Referring to fig. 15, an embodiment of the present invention further provides a method for controlling a mobile terminal, including the following steps:

step 801, when detecting that the mobile terminal establishes a call service, detecting the position of a currently used display screen.

It should be noted that the call setup service includes a case where the receiver has been enabled to perform a call, and a case where incoming and outgoing calls are answered and the receiver is not enabled to perform a call.

The mobile terminal provided by the embodiment of the invention comprises a first surface and a second surface which are arranged back to back, wherein the first surface and the second surface are both provided with display screens. When the mobile terminal is detected to establish a call service, incoming call information is displayed on a display screen of the mobile terminal, a user needs to use the mobile terminal to carry out a call, and at the moment, the position of the display screen currently used by the mobile terminal is detected. I.e. whether a first-side display or a second-side display is currently used. When the mobile terminal receives an incoming call, the display screen on the first side and the display screen on the second side of the mobile terminal can display incoming call information.

It should be noted that the mobile terminal may be a proximity sensor, an infrared sensor, a pressure sensor, or the like to detect whether the display screen of the first side or the display screen of the second side is currently used.

And 802, when the currently used display screen is detected to be positioned on the first channel, controlling the adjusting mechanism to open the first channel and close the second channel.

For example, the first surface and the second surface are both provided with infrared sensors, and when the mobile terminal receives an incoming call, if the infrared sensor arranged on the first surface detects that the head of a user is close to the mobile terminal, it is determined that the currently used display screen is located on the first surface. Or when the user touches the display screen on the first surface to dial out the phone, the pressure sensor arranged on the first surface receives the touch signal, and then the currently used display screen is judged to be positioned on the first surface.

It should be noted that a receiver, a sound guiding channel and an adjusting mechanism are arranged in the mobile terminal, the sound guiding channel comprises a main channel, and a first channel and a second channel which are communicated with the main channel, the first surface is provided with a first sound outlet communicated with the first channel, the second surface is provided with a second sound outlet communicated with the second channel, the receiver is arranged at one end of the main channel, the adjusting mechanism is arranged in the sound guiding channel and used for opening the first channel and closing the second channel, or used for opening the second channel and closing the first channel, and the adjusting mechanism can be a processor connected with the mobile terminal.

For example, the first surface and the second surface of the mobile terminal are both provided with infrared sensors, when the mobile terminal receives an incoming call, if the first infrared sensor on the first surface detects that the head of a user is close to the mobile terminal, the first infrared sensor outputs a signal to the processor, the processor receives the signal transmitted by the first infrared sensor and then sends a control signal to the adjusting mechanism so as to control the adjusting mechanism to conduct the main channel and the first channel and close the second channel, at this time, the receiver can only transmit sound to one side of the first surface of the mobile terminal through the main channel and the first channel, and the second sound outlet hole on the second surface cannot play sound. Therefore, the sound of the telephone receiver is ensured to be transmitted from the first sound output hole of the first surface, the second sound output hole of the second surface can not transmit the sound, and the sound quality played by the telephone receiver is ensured.

And 803, when the display screen currently used is detected to be positioned at the second surface, controlling the adjusting mechanism to open the second channel and close the first channel.

In the same principle, when the mobile terminal receives an incoming call, if the infrared sensor arranged on the second surface detects that the head of the user is close to the mobile terminal, the currently used display screen is judged to be positioned on the second surface. Or when the user touches the display screen on the second surface to dial out the phone, the pressure sensor arranged on the second surface receives the touch signal, and then the currently used display screen is judged to be positioned on the second surface.

For example, if the second infrared sensor on the second surface detects that the head of the user is close to the second surface, the second infrared sensor outputs a signal to the processor, the processor receives the signal transmitted by the second infrared sensor and then sends a control signal to the adjusting mechanism to control the adjusting mechanism to conduct the main channel and the second channel and close the first channel, at this time, the receiver can only transmit sound to one side of the second surface of the mobile terminal through the main channel and the second channel, and the first sound outlet hole on the first surface cannot play sound. Therefore, the sound of the telephone receiver is ensured to be transmitted from the second sound output hole of the second surface, the first sound output hole of the first surface can not transmit the sound, and the sound quality played by the telephone receiver is ensured.

It should be noted that, a specific implementation manner of the adjusting mechanism may refer to the technical scheme in the foregoing mobile terminal embodiment, and details are not described in this embodiment.

In the embodiment of the invention, when the mobile terminal is detected to establish the call service, the position of the currently used display screen is detected; when the currently used display screen is detected to be positioned on the first surface, controlling the adjusting mechanism to open the first channel and close the second channel; and when the display screen currently used is detected to be positioned on the second surface, controlling the adjusting mechanism to open the second channel and close the first channel. Therefore, when the mobile terminal establishes a call service, the position of the currently used display screen is detected to control the adjusting mechanism to adjust the sound propagation path of the telephone receiver, so that when the display screens on different sides of the mobile terminal are used, sound is only played from the side, the sound quality played by the telephone receiver is ensured, and the control of the mobile terminal is more intelligent.

After the step 803, the method further includes:

when the currently used display screen is detected to be replaced, the adjusting mechanism is controlled to move so as to close the channel in the opening state and open the channel in the closing state.

It can be understood that, when the user performs a call service, that is, when the mobile terminal has already started the receiver to perform a call, it is determined whether the mobile terminal is turned over. The flipping may be from a first side currently in use to a second side, or from a second side currently in use to a first side, which all require the user to flip the mobile terminal.

In the embodiment of the present invention, whether the mobile terminal is turned over may be detected by an angular velocity sensor, a pressure sensor, an infrared sensor, a proximity sensor, and the like provided in the mobile terminal.

If the mobile terminal is turned over, the adjusting mechanism may be controlled to open the second channel and close the first channel. That is to say, when it is detected that the mobile terminal is turned over from the first face currently used to the second face, and the sound to be played by the receiver is transmitted from the second sound output hole of the second face, the adjusting mechanism is controlled to conduct the main channel and the second channel to close the first channel.

For example, the mobile terminal currently uses the first surface, the first infrared sensor of the first surface can detect a signal that the head of the user is close to, when the mobile terminal is turned over, the first infrared sensor of the first surface does not detect the signal, the second infrared sensor of the second surface can detect a signal that the head of the user is close to, and it can be determined that the mobile terminal is turned over. At this time, sound originally played from the first sound outlet hole needs to be played from the second sound outlet hole, and the adjusting mechanism is controlled to conduct the main channel and the second channel to close the first channel.

Or, when it is detected that the mobile terminal is turned over from the currently used second surface to the used first surface, and at this time, the sound to be played by the receiver is transmitted from the first sound output hole of the first surface, the adjusting mechanism is controlled to open the first channel and close the second channel.
