Specifically, when the speaker device includes a flexible printed circuit board connected to both the speaker and the rotary connection structure, the flexible printed circuit board is connected to a controller of the electronic device.
It should be further noted that, as shown in fig. 8, another embodiment of the present invention further provides a speaker sound output control method applied to the electronic device, including:
step 801, when a sound outlet of a speaker device faces a preset sound outlet of an electronic device, outputting a first control signal to a rotary connecting structure, so that the rotary connecting structure controls the speaker device to be in a preset state according to the first control signal;
it should be noted that the preset sound outlet is a first sound outlet, the preset state is a second state, and when the preset state is the second state, the sound outlet is opposite to the second sound outlet, that is, when the rotating connection structure receives the first control signal, the rotating connection structure controls the sound outlet of the speaker device to face the second sound outlet;
the preset sound outlet is a second sound outlet, the preset state is a first state, and the sound outlet is opposite to the first sound outlet in the first state, namely when the rotating connection structure receives a first control signal, the rotating connection structure controls the sound outlet of the loudspeaker device to face the first sound outlet.
Further, the above steps are specifically described from the electronic device automatic control and user active triggering as follows.
Situation one, automatic control of electronic equipment
In this case, the specific implementation manner of the step 801 is as follows:
detecting whether a preset sound outlet hole of the electronic equipment is shielded or not;
and if the preset sound outlet hole of the electronic equipment is blocked, outputting a first control signal to the rotating connection structure.
Further, before outputting the first control signal to the rotating connection structure, it is also necessary to determine whether the speaker device is in a sound playing state; and if the loudspeaker device is in a sound playing state, outputting a first control signal to the rotary connecting structure.
Specifically, the implementation means is as follows:
when the loudspeaker device is currently in sound playing, the sound outlet is opposite to the first sound outlet, and the first sound outlet is shielded, outputting a first control signal to the rotating connection structure, so that the rotating connection structure controls the sound outlet to be switched from a first state to a second state according to the first control signal;
when the loudspeaker device is currently in sound playing, the sound outlet is opposite to the second sound outlet, and the second sound outlet is shielded, a first control signal is output to the rotating connecting structure, so that the rotating connecting structure controls the sound outlet to be switched from the second state to the first state according to the first control signal.
In this embodiment, when a user plays a sound using a certain state of the speaker device, if the sound output hole in the certain state is blocked, another state of the speaker device is automatically adjusted to play the sound, that is, the sound is output through the sound output hole that is not blocked.
Further, in this case, for the convenience of use of the user, the electronic device may set a default state of the speaker device, and when the preset state is the second state and the speaker device is not currently in the sound playing state, output a second control signal to the rotating connection structure, so that the rotating connection structure controls the speaker device to switch from the second state to the first state according to the second control signal.
It should be noted that, when the state of the speaker apparatus is not the default state, and the playback condition in the current state is not met, the speaker apparatus will automatically return to the default state.
For example, the electronic device is a mobile phone, when a user uses the mobile phone, the screen state of the mobile phone has two use states of a horizontal screen and a vertical screen, and the first state (the lower sound outlet hole is used for playing sound, namely the lower sound outlet state) of the speaker device is set as a default sound outlet state; when a user watches a video program on a horizontal screen, due to the holding posture of the user, the sound outlet hole below the display surface is shielded, and when the sound outlet hole below the display surface is shielded, the mobile phone adjusts the loudspeaker device to be in a second state (the side sound outlet hole is used for playing sound, namely, the side sound outlet state), so that the video sound is not shielded, and the user is facilitated to watch the video; when the user exits the horizontal screen mode and holds the mobile phone in the vertical screen mode to listen to music, the mobile phone can adjust the loudspeaker device to be in the second state at the previous moment, the holding posture of the user can have the condition of shielding the sound outlet hole on the side edge of the display surface in the vertical screen mode, and when the sound outlet hole on the side edge of the display surface is shielded, the mobile phone can adjust the loudspeaker device to be in the first state, so that the music sound is ensured not to be shielded, and the music listening method is favorable for the user to enjoy music. When the user holds the mobile phone in the vertical screen mode to listen to music and the mobile phone adjusts the loudspeaker device to be in the second state, the user suddenly turns off the music and the loudspeaker device plays no sound, and at the moment, the loudspeaker device needs to be restored to the default sound state.
Second, user active triggering
In this case, the specific implementation manner of the step 801 is as follows:
and receiving a control instruction, and outputting a first control signal to the rotary connection structure according to the control instruction.
Further, the control instruction is received through a touch screen or a physical key on the electronic device, and the control instruction is used for indicating that the state switching of the loudspeaker device is required.
It should be noted that a touch key may be arranged on a touch screen of the electronic device, or a physical key (for example, a pressing key is arranged on a side of the electronic device) may be arranged on the electronic device, and the control instruction is received by collecting an operation of the user on the touch key or the physical key.
It should be noted that, the electronic device may be provided with a selection switch for switching the state of the speaker device, for example, by touching a key, and the selection switch may be used to select between automatic switching (corresponding to the first case) and manual switching (corresponding to the second case). When the user starts the manual switching, the automatic switching function is disabled, and the user can automatically select the playing mode of the lower sound or the side sound according to the actual use scene.
According to the embodiment of the invention, the sound emitting direction of the loudspeaker device is switched according to scenes, so that a user does not need to adjust the hand-holding posture deliberately in different using states, and the listening experience of the user is improved.
It should be noted that the electronic devices mentioned in the embodiments of the present invention include, but are not limited to, a mobile phone, a tablet computer, a notebook computer, a palm computer, a vehicle-mounted terminal, a wearable device, a pedometer, and the like.
While the preferred embodiments of the present invention have been described, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined in the following claims.
