A playback component is arranged in the box body, an installation cavity is formed in the box wall, and a microphone charging bin for placing the microphone for charging is embedded in the installation cavity. After the user finishes singing, the microphone can be placed in the charging bin for charging. After the user finishes singing, they often forget to turn off the microphone. In the process of putting the microphone into the charging bin, the microphone will continuously pick up ambient sounds and send them to the playback device for amplification and playback. At this time, the microphone is relatively close to the playback device, and the sound played by the playback device will be picked up by the microphone again and sent to the playback device for amplification and playback, thus forming a positive feedback loop. This loop continues continuously and will generate a very loud howling sound. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide the hardware structures of a playback device and a microphone for software engineers, so that after programming the hardware structures, in the process of putting the microphone into the charging bin of the playback device, howling caused by forgetting to turn off the microphone can be avoided.

[0005] To solve the above technical problem, the utility model provides a playback device, which includes a box body and a playback component arranged on the box body.

[0022] The following further elaborates on the present invention in detail in combination with the specific implementation manners.

[0023] The singing device, as Figure 1 shown, includes a playback device 1 and two microphones 4. The playback device 1 includes a box body 2, and a charging bin 5 for placing the two microphones 4 for charging is provided at the top of the box body 2. As Figure 2 shown, a playback component 3 is provided on the box body 2, and a dust-proof net cover 18 is installed in front of the playback component 3. The dust-proof net cover 18 covers the playback component 3 to prevent dust. In this embodiment, the two microphones 4 are paired with the playback device 1 so that the sound picked up by the microphones 4 can be amplified and played through the playback component 3 of the playback device 1.

[0024] As Figure 3 and Figure 4 shown, the charging bin 5 has two cylindrical chambers so that the two microphones 4 can be respectively placed. A charging output terminal 6 is provided below the bottom wall 16 of the charging bin 5. Specifically, the charging output terminal 6 is a wireless charging transmitting coil facing the charging bin 5. A host infrared transmitting device 7 and a host infrared receiving device 8 are also provided below the bottom wall 16 of the charging bin 5. The bottom wall 16 of the charging bin 5 is made of an infrared-transmitting material. The host infrared transmitting device 7 and the host infrared receiving device 8 face upward and face the cylindrical chambers of the charging bin 5 through the infrared-transmitting bottom wall 16. A host controller 9 electrically connected to the host infrared transmitting device 7 and the host infrared receiving device 8 respectively is also provided below the bottom wall 16 of the charging bin 5. The host controller 9 is a PCB circuit board integrated with a single-chip microcomputer, and the host controller 9 controls the host infrared transmitting device 7 and the host infrared receiving device 8 to perform infrared signal transceiver work.

[0025] Above the bottom end 17 of the microphone 4, there is a charging input terminal 10, which is specifically a wireless charging receiving coil arranged downward. When the microphone 4 is placed in the charging bin 5, the charging output terminal 6 conducts energy to the charging input terminal 10 based on the principle of inductive coupling, and then the charging input terminal 10 converts the energy into electric energy to charge the microphone 4. Above the bottom end 17 of the microphone 4, there are also a microphone infrared transmitting device 11 and a microphone infrared receiving device 12. The bottom end 17 of the microphone 4 is made of an infrared-transmitting material, and the microphone infrared transmitting device 11 and the microphone infrared receiving device 12 face downward and face the outside through the infrared-transmitting bottom wall 16. In this embodiment, the direction in which the microphone 4 is placed in the charging bin 5 is specifically downward, which is the same as the orientation of the microphone infrared transmitting device 11 and the microphone infrared receiving device 12, while the host infrared transmitting device 7 and the host infrared receiving device 8 face upward towards the charging bin 5. Then, during the process of placing the microphone 4 in the charging bin 5, the microphone infrared transmitting device 11 and the microphone infrared receiving device 12 face the host infrared receiving device 8 and the host infrared transmitting device 7 to achieve infrared data interaction. Above the bottom end 17 of the microphone 4, there is also a microphone controller 13 that is electrically connected to the microphone infrared transmitting device 11 and the microphone infrared receiving device 12 respectively. The microphone controller 13 is a PCB circuit board integrated with a single-chip microcomputer, and the microphone controller 13 controls the microphone infrared transmitting device 11 and the microphone infrared receiving device 12 to perform infrared signal transmission and reception work.

[0026] As Figure 5 and Figure 6 shown, the bottom of the microphone 4 is provided with an outward flange 15, and an electromagnetic lock 14 is provided beside the charging bin 5. The electromagnetic lock 14 has a telescopic locking rod, and the electromagnetic lock 14 is electrically connected to the host controller 9. The host controller 9 controls the telescopic locking rod of the electromagnetic lock 14 to extend for locking or retract for unlocking. In the locked state where the telescopic locking rod of the electromagnetic lock 14 extends, the telescopic locking rod extends into the charging bin 5 to catch the outward flange 15 of the microphone 4, thereby locking the microphone 4 placed in the charging bin 5.

[0027] In this embodiment, the microphone controller 13 transmits an infrared signal containing microphone status information outward through the microphone infrared transmitting device 11, and the host controller 9 detects the infrared signal from the microphone 4 in real time through the host infrared receiving device 8. If the host infrared receiving device 8 fails to detect the infrared signal, it means that the microphone 4 is not placed in the charging bin 5 for charging, and the host controller 9 continues to detect the infrared signal from the microphone 4 in real time through the host infrared receiving device 8; if the host infrared receiving device 8 detects the infrared signal, it means that the microphone 4 is being placed in the charging bin 5 for charging. Therefore, the host controller 9 obtains the microphone status information from this infrared signal, and judges whether the microphone 4 is in the shutdown state according to this microphone status information. If the microphone 4 is not in the shutdown state, the host controller 9 sends a non-recording signal to the microphone 4 through the host infrared transmitting device 7. If the microphone 4 is in the shutdown state, the host controller 9 does not send a non-recording signal to the microphone 4 through the host infrared transmitting device 7. The microphone controller 13 detects the non-recording signal from the playback device 1 in real time through the microphone infrared receiving device 12. If the non-recording signal is detected, it controls the microphone 4 to enter the corresponding non-recording state, and the microphone 4 cannot pick up sound after entering the non-recording state. Among them, the non-recording signal sent by the host infrared transmitting device 7 to the microphone 4 includes a mute signal or a shutdown signal, which is selected according to the actual situation. If the signal sent by the host infrared transmitting device 7 is a mute signal, the microphone controller 13 controls the microphone 4 to enter the mute state after detecting this mute signal. If the signal sent by the host infrared transmitting device 7 is a shutdown signal, the microphone controller 13 controls the microphone 4 to enter the shutdown state after detecting this shutdown signal.

[0028] When the user picks up the microphone 4 to sing and the bottom end 17 of the microphone 4 is not facing the bottom wall 16 of the charging bin 5, the host infrared receiving device 8 cannot detect the infrared signal from the microphone infrared transmitting device 11. When the user puts the microphone 4 into the charging bin 5 of the playback device 1 for charging after singing and the bottom end 17 of the microphone 4 faces the bottom wall 16 of the charging bin 5, the microphone infrared transmitting device 11 will send an infrared signal containing microphone status information to the host infrared receiving device 8 of the playback device 1. At this time, if the user forgets to turn off the microphone 4, the host controller 13 will judge that the microphone 4 is not in the shutdown state according to the microphone status information in the infrared signal, and then send a non-recording signal to the microphone infrared receiving device 12 through the host infrared transmitting device 7. After the microphone infrared receiving device 12 detects the non-recording signal, the microphone controller 13 controls the microphone 4 to enter the corresponding non-recording state, so that the microphone 4 cannot pick up the sound of the playback device 1 and avoid forming a positive feedback loop to generate howling.

[0029] The above is only the implementation mode of the present invention, and does not limit the scope of patent protection. Those skilled in the art make non-substantial changes or substitutions based on the present invention, and still fall within the scope of patent protection.
