To take the earphone on the left side in fig. 3 as the first playing part 21 and the earphone on the right side as the second playing part 22, one end of the first conducting wire 214 is connected to the first conductive member 212, and the other end is connected to the first voltage signal, where the first voltage signal may be a 0 voltage signal or a voltage signal greater than 0, and the voltage signal greater than 0 may be: a second voltage signal, or a battery voltage signal, or a supply voltage signal, as described below.

In the embodiment of the present application, the audio apparatus 20 further includes a feedback device 24, the feedback device 24 includes a first end and a second end, the first end is connected to the second conductive member 222, and the second end is connected to the processing portion 23; the feedback device 24 is configured to output a second voltage signal or a 0 voltage signal to the processing unit 23 through the second terminal according to whether the first terminal is connected to the first voltage signal when the connection state of the first conductor 212 and the second conductor 222 changes, so that the processing unit 23 controls the power state of the audio device 20.

It should be noted that, in the embodiment of the present application, the feedback device 24 is disposed outside the first playing section 21 and the second playing section 21, for example, the feedback device 24 may be disposed inside a collar of the audio apparatus 20, further, the feedback device 24 may be disposed beside the processing section 23, or the feedback device 24 may be integrated with the processing section 23, so that the design compactness of the audio apparatus 20 can be improved. In other embodiments, the feedback device 24 may be disposed inside the second playing section 22.

The power states may be a first power consumption state, a second power consumption state, a third power consumption state and a fourth power consumption state, in which the power consumption of the audio apparatus 20 increases sequentially in the first power consumption state, the second power consumption state, the third power consumption state and the fourth power consumption state, the first power consumption state may be a shutdown state, the second power consumption state may be a sleep state, the third power consumption state may be a standby state, and the fourth power consumption state may be a startup state or a startup state. For example, in the embodiment of the present application, when the second terminal outputs the second voltage signal to the processing unit 23, the processing unit 23 controls the audio apparatus 20 to be powered on or powered on, and when the second terminal outputs the 0 voltage signal to the processing unit 23, the processing unit 23 controls the audio apparatus 20 to be powered off. In other embodiments, when the second terminal outputs the second voltage signal to the processing unit 23, the processing unit 23 controls the audio device 20 to start, and when the second terminal outputs the 0 voltage signal to the processing unit 23, the processing unit 23 controls the audio device 20 to stand by or sleep, but of course, the processing unit 23 may also control the audio device 20 to be in other states as listed above, which is not exhaustive in the embodiments of the present application.

In the present embodiment, the feedback device 24 is a passive device, i.e., no power is required to power the feedback device 24. For example, the feedback device 24 may be implemented by one MOS transistor or a combination of at least two MOS transistors, or the feedback device 24 may be implemented by one or at least two amplifiers, or one or at least two transistors. The input end of the feedback device 24 may be connected to the second voltage signal, the output end of the feedback device 24 may be connected to the processing portion 23, and the control end of the feedback device 24 may be connected to the second conductive member 222, so as to control whether the feedback device 24 is turned on or not by whether the second conductive member 222 is connected to the first voltage signal, so that the processing portion 23 receives the second voltage signal when the feedback device 24 is turned on, and the processing portion 23 receives the 0 voltage signal when the feedback device 24 is not turned on. The second voltage signal may be the same as the first voltage signal, e.g., the second voltage signal and the first voltage signal are both a supply voltage signal or a battery voltage signal.

In the embodiment of the present application, when the first conductor 212 and the second conductor 222 are switched from being separated to being connected, the feedback device 24 transmits the second voltage signal or the 0 voltage signal to the processing portion 23 according to the first voltage signal that can be accessed. When the first conductive member 212 and the second conductive member 222 are switched from being connected to being separated from each other, the feedback device 24 transmits the 0 voltage signal or the second voltage signal to the processing unit 23 according to the first voltage signal which cannot be accessed. The processing unit 23 may control the audio apparatus 20 to start up according to the second voltage signal, and control the audio apparatus 20 to shut down according to the 0 voltage signal.

It can be understood that, when the first conductive member 212 and the second conductive member 222 are switched from being separated to being connected, the first playing part 21 and the second playing part 22 are also switched from being separated to being connected. When the first conductor 212 and the second conductor 222 are switched from connection to separation, the first playing part 21 and the second playing part 22 are also switched from connection to separation. The feedback device 24 is capable of receiving the first voltage signal when the first conductive member 212 is coupled to the second conductive member 222 and the feedback device 24 is not capable of receiving the first voltage signal when the first conductive member 212 is decoupled from the second conductive member 222. Of course, in other embodiments, the first voltage signal may not be obtained by connecting the first conductive member 212 to the second conductive member 222, for example, the feedback device 24 may sense the first voltage signal according to capacitance, inductance, etc., as long as the distance between the first conductive member 212 and the second conductive member 222 is less than a specific distance.

In one embodiment, the connection between the first playing part 21 and the second playing part 22 may be a pull-in connection between the first playing part 21 and the second playing part 22, that is, the first conductive member and the second conductive member are connected together by magnetic force. In another embodiment, the connection may be by means of a snap or adhesive connection.

Because the feedback device 24 is a passive device, the audio device 20 does not need to supply power to the feedback device 24, the standby power consumption of the audio device 20 can be reduced, the power consumption during shutdown is obviously reduced, the storage time of the audio device 20 is prolonged, the feedback device 24 does not need to consume power during shutdown, and the shutdown current is reduced. Since the connection between the first conductive member 212 and the second conductive member 222 is determined by the feedback device 24 according to whether the first voltage signal is received, the determination is simple. In addition, due to the mechanical structure of the key switch, abrasion is generated along with the use times of users, the control mode is insensitive, and the mechanical structure is not adopted for control in the application, so that the reliability of the product is obviously improved.

In the embodiment of the application, when the connection state of the first conductive piece and the second conductive piece is changed, the processing part controls the power state of the audio device, so that the running state of the audio device can be controlled without the need of operating a physical key on the audio device by a user, and the operation mode adopted by the user for controlling the running state of the audio device is simple.

With reference to fig. 2, based on the foregoing embodiment, the present application provides an audio apparatus, where the audio apparatus 20 includes a first playing portion 21, a second playing portion 22 and a processing portion 23, and the specific structures of the first playing portion 21, the second playing portion 22 and the processing portion 23 may be the same as those of the foregoing embodiment.

In the embodiment of the present application, the processing portion 23 includes a power supply port and a detection port.

The power supply port can receive a second voltage signal or a 0 voltage signal transmitted by the feedback device 24, and the processing part 23 is used for accessing the second voltage signal to be powered up through the power supply port when the second voltage signal is input; the detection port is used for detecting the second voltage signal or the 0 voltage signal transmitted by the feedback device 24, and the processing portion 23 is used for controlling the audio apparatus 20 to start up through the second voltage signal detected by the detection port.

In other embodiments of the present application, in order to avoid the problem that the service life of the processing unit 23 is reduced due to frequent turning on or off of the processing unit 23, the power supply port of the processing unit 23 may be directly connected to the power supply voltage signal or the second voltage signal, so that the processing unit 23 is in a state of being powered on all the time, and thus the audio device 20 is started by detecting the second voltage signal detected by the port, and the audio device 20 is turned off by detecting the 0 voltage signal detected by the port.

In the embodiment of the present application, when the audio apparatus is turned off, that is, when the feedback device outputs a 0-voltage signal to the processing unit, the audio apparatus does not supply power (or power up) to the processing unit, and the processing unit is in an inoperative state, and the audio apparatus is not controlled any more, or the audio apparatus is controlled to be in a turned-off state; when the feedback device 24 inputs the second voltage signal to the power supply port and the detection port, the power supply port supplies power (or powers on) through the second voltage signal, the processing part works, and the detection port detects the second voltage signal to control the audio device to start. In this way, the processing unit consumes no power when the audio apparatus is turned off, and power consumption of the audio apparatus can be reduced.

In order to prevent the user from performing an erroneous operation on the audio apparatus 20, for example, the user needs to temporarily separate two playback units, and if the audio apparatus 20 switches the operation mode, the user may be adversely affected. In order to solve this problem of the user's erroneous operation, the processing section may have a delay function, for example, the processing section 23 for controlling the audio apparatus 20 to be started up when the second voltage signal is continuously input for a period longer than the first period, and/or for controlling the audio apparatus 20 to be shut down when the 0 voltage signal is continuously input for a period longer than the second period.

In one embodiment, the processing portion 23 may or may not turn on the delay function based on a user operation. For example, the audio apparatus 20 may have a preset physical key, and the audio apparatus 20 may turn on or off the delay function by a user operating the preset physical key; for another example, the audio apparatus 20 may have a voice input module, and the audio apparatus 20 may receive a voice input of a user through the voice input module, and turn on or off the delay function according to the voice input of the user; for another example, the audio apparatus 20 may include a wireless connection module (e.g., a bluetooth module and/or a WIFI module), and communicate with a terminal device (e.g., a mobile phone or a computer) through the wireless connection module, so that the audio apparatus 20 turns on or off the delay function through the operation of the terminal device by the user.

In one embodiment, the power supply port of the processing portion 23 may have a delay function, for example, the processing portion 23 may include a delay module (not shown) configured to enable the power supply port of the processing portion 23 to determine that the duration of the continuous input of the second voltage signal is longer than the first duration when the second voltage signal is received, and to enable the power supply port of the processing portion 23 to control the audio device 20 to be powered off when the duration of the continuous input of the 0 voltage signal is longer than the second duration when the 0 voltage signal is received.

In another embodiment, the second voltage signal or the 0 voltage signal may be directly Input to a detection port or an Input/Output (I/O) port of the processing portion 23. When the processing part 23 determines that the detected voltage signal is changed from the second voltage signal to a 0 voltage signal and the duration of the continuous input of the 0 voltage signal is longer than the second duration, the audio device 20 is controlled to be turned off; when the processing portion 23 determines that the detected voltage signal is changed from the 0 voltage signal to the second voltage signal and the duration of the continuous input of the second voltage signal is longer than the first duration, the audio device 20 is controlled to be started. The first and second durations may be the same or different.

For example, in one embodiment, the processing portion 23 may start a first timer when determining that the detected voltage signal is changed from the 0 voltage signal to the second voltage signal, where the duration of the first timer is a first duration, and control the audio apparatus 20 to start when the first timer times out when the voltage signal detected during the operation time of the first timer is still the second voltage signal; the processing unit 23 may start a second timer when it is determined that the detected voltage signal is changed from the second voltage signal to the 0 voltage signal, where the duration of the second timer is a second duration, and when the voltage signal detected within the running time of the second timer is still a 0 level signal, the processing unit controls the audio apparatus 20 to shut down when the second timer times out.

In one embodiment, the processing unit 23 is configured to control the audio apparatus 20 to stand by before controlling the audio apparatus 20 to power off. When the detection port of the processing portion 23 detects that the change of the voltage signal is changed from the 0 voltage signal to the second voltage signal, the audio device 20 is controlled to be in a standby state, and after the standby time duration lasts for the first time duration, the audio device 20 is controlled to be started, or in other words, when the first timer is overtime, the audio device 20 is controlled to be started, and/or, when the detection port of the processing portion 23 detects that the change of the voltage signal is changed from the second voltage signal to the 0 voltage signal, the audio device 20 is controlled to be in a standby state, and after the standby time duration lasts for the second time duration, the audio device 20 is controlled to be shut down, or in other words, when the second timer is overtime, the audio device 20 is controlled to be shut down.

In the embodiment of the application, the playing part is controlled to be turned on or turned off in a delayed manner, so that misoperation of a user can be avoided.

It should be understood that the processing portion includes a power supply port and a detection port, and both the power supply port and the detection port are used for receiving the 0 voltage signal/the second voltage signal, which may be combined with a scheme that the audio device has a delay function.

In order to maintain the connection between the first and second playback sections 21, 22, this can be achieved by: the first playing part 21 further includes a first magnetic component 215 disposed therein, and the second playing part 22 further includes a second magnetic component 225 disposed therein, for connecting the first conductive component 212 and the second conductive component 222 when the first magnetic component 215 and the second magnetic component 225 approach each other.

In another embodiment, the second conductive member may be a magnetic conductive material, and the first playing portion 21 further includes a third magnetic member (not shown) disposed therein, for connecting the first conductive member 212 and the second conductive member 222 when the third magnetic member is close to the second conductive member 222.

In another embodiment, the first conductive member may be a magnetic conductive material, and the second playing portion 22 further includes a fourth magnetic member (not shown) disposed therein for connecting the first conductive member 212 and the second conductive member 222 when the fourth magnetic member is close to the first conductive member 211.

The first magnetic member 215 in the above-described embodiment may be disposed at a position close to the first conductive member 212, and/or the second magnetic member 225 may be disposed at a position close to the second conductive member 222, so that the attractive force between the first conductive member 212 and the second conductive member 222 can be increased.

Through the mode, in the practical application scene, two earphone heads are in the same place in the suction when the earphone does not work, and as long as the user pulls open the earphone head, the earphone just starts up, and the earphone begins to match equally this moment, prepares to play the music, need not additionally go to press the physics button.

In the embodiment of the application, the magnetic part is arranged, so that the first conductive part and the second conductive part are easy to establish reliable connection.

In the embodiment of the present application, the feedback device 24 is specifically configured to: when the connection state of the first conductor 212 and the second conductor 222 is switched from the separation state to the connection state, the first end is connected to the first voltage signal, the second end is controlled to output a 0 voltage signal to the processing unit 23, and the processing unit 23 is triggered to control the audio device 20 to shut down; when the connection state of the first conductive member 212 and the second conductive member 222 is switched from connection to separation, the first end is not connected to the first voltage signal, the second end is controlled to output the second voltage signal to the processing unit 23, and the processing unit 23 is triggered to control the audio device 20 to start.

In the present embodiment, the feedback device 24 further includes a third terminal; the third end is connected with a second voltage signal; a feedback device 24 for cutting off the second terminal and the third terminal when the first terminal is connected to the first voltage signal, so that the second terminal outputs a 0 voltage signal to the processing unit 23; when the first terminal is not connected to the first voltage signal, the second terminal and the third terminal are turned on, and the second terminal outputs a second voltage signal to the processing unit 23.
