In some embodiments, as shown in FIG. 3 , the TWS earphone is an in-ear earphone; the through hole 211 is an inclined hole and is inclined in a direction away from the mounting hole 214 of the accessory speaker 220. By such a configuration, compared with the normal wearing of the TWS earphone, the TWS earphone 300 is inverted in the present application, so that the sound source generated by the accessory speaker 220 is away from the sound source generated by the earphone speaker 310, which can further improve the sound quality of the earphone.

In some embodiments, as shown in FIG. 4 , an accessory metal contact 215 is provided in the earphone mounting cavity 213 for achieving electrical connection between the accessory earphone 10 and the TWS earphone 300 .

An embodiment of the present application provides a composite earphone, including a TWS earphone 300 and the accessory earphone 10 involved in the above embodiment. As shown in FIG5, when the TWS earphone 300 is in the earphone installation cavity 213 of the accessory earphone 10, the joint working mode is triggered, and the TWS earphone 300 and the accessory earphone 10 work together. As shown in FIG6, when the TWS earphone 300 is not in the earphone installation cavity 213 of the accessory earphone 10, the TWS earphone 300 works alone, and the accessory earphone 10 is in a dormant state.

In some embodiments, as shown in FIG. 7 , the accessory headset 10 further includes an accessory power supply 260 , an accessory microphone 250 , and an accessory controller 240 . The accessory controller 240 is connected to the accessory microphone 250 , and the accessory controller 240 is also connected to the accessory power supply 260 . The accessory controller 240 is also connected to the accessory speaker 220 .

The accessory power supply 260 supplies power to the accessory speaker 220, the accessory controller 240, and the accessory microphone 250. The accessory controller 240 sends the audio signal to be played to the accessory speaker 220, so that the accessory speaker 220 plays the audio signal to be played. The accessory microphone 250 is used to collect the ambient sound signal in the environment, and the accessory microphone 250 also transmits the collected ambient sound signal to the accessory controller 240.

In some embodiments, as shown in FIG7 , the TWS headset 300 further includes a headset power supply 350, a headset microphone 320, a headset controller 330, and a Bluetooth communication module 340.

The headphone power supply 350 supplies power to the headphone speaker 310, the Bluetooth communication module 340, the headphone controller 330 and the headphone microphone 320. The headphone microphone 320 is used to collect the ambient sound signal in the environment, and the headphone microphone 320 transmits the collected ambient sound signal to the headphone controller 330. The Bluetooth communication module 340 is used to transmit the collected ambient sound signal to the outside. The headphone controller 330 sends the audio signal to be played to the headphone speaker 310, so that the headphone speaker 310 plays the audio signal to be played.

The TWS earphone 300 can work independently. Since the TWS earphone 300 is provided with a Bluetooth communication module 340, it can receive an externally transmitted audio signal to be played, and the earphone controller 330 decodes the audio signal and transmits it to the earphone speaker 310, and the earphone speaker 310 plays the audio signal to be played, so that the TWS earphone 300 can work independently.

The accessory earphone 10 cannot work independently and needs to rely on the TWS earphone 300 to work. As shown in FIG4 , the earphone mounting cavity 213 of the accessory earphone 10 is provided with an accessory metal contact 215, and as shown in FIG8 , the TWS earphone 300 is provided with an earphone metal contact 301. When the TWS earphone 300 is located in the earphone mounting cavity 213, the accessory metal contact 215 of the accessory earphone 10 and the earphone metal contact 301 of the TWS earphone 300 contact each other, so that the accessory controller 240 and the earphone controller 330 are connected to each other.

The accessory controller 240 receives the audio signal to be played sent by the earphone controller 330, decodes the audio signal to be played and transmits it to the accessory speaker 220, and the accessory speaker 220 plays the audio signal, thereby enabling the accessory earphone 10 to work dependently on the TWS earphone 300.

In some embodiments, the accessory metal contact 215 is a resilient metal connecting post.

In some embodiments, magnets are provided in both the accessory earphone 10 and the TWS earphone 300 . When the TWS earphone 300 is installed in the earphone installation cavity 213 , magnetic force is generated in the accessory earphone 10 and the TWS earphone 300 , so that the TWS earphone 300 is fixed in the accessory earphone 10 .

In some embodiments, the accessory controller 240 receives the first audio signal sent by the headset controller 330 when the TWS headset 300 is installed in the headset installation cavity 213. The accessory controller 240 also sends the first audio signal to the accessory speaker 220, so that the accessory speaker 220 plays the first audio signal. The headset controller 330 also sends the second audio signal to the headset speaker 310, so that the headset speaker 310 plays the second audio signal. By cooperating with two speakers that emit different sound frequencies, the sound quality of the headset is improved in the limited space of the sound cavity 212.

In some embodiments, when the TWS earphone 300 is installed in the earphone installation cavity 213, the accessory microphone 250 and the earphone microphone 320 in the TWS earphone 300 form a microphone array, and the microphone array collects sound signals in the environment.

After the microphone array collects the user's voice, the accessory microphone 250 collects the user's voice and outputs a first sound signal, and the headphone microphone 320 collects the user's voice and outputs a second sound signal.

Since the accessory metal contact 215 of the accessory earphone 10 and the earphone metal contact 301 of the TWS earphone 300 are in contact with each other, the accessory controller 240 and the earphone controller 330 are connected to each other, and the accessory microphone 250 sends the first sound signal to the accessory controller 240. The accessory controller 240 transmits the first sound signal to the earphone controller 330. The earphone controller 330 also receives the second sound signal transmitted by the earphone microphone 320. The earphone controller 330 processes the first sound signal and the second sound signal and sends them to the Bluetooth communication module 340, which transmits them to the outside.

In the above technical solution, when the TWS earphone 300 is installed in the earphone installation cavity 213, the accessory earphone 10 can share the Bluetooth communication module 340 with the TWS earphone 300, and there is no need to set communication components in the accessory earphone 10, thereby reducing costs.

In some embodiments, when the TWS headset 300 and the accessory headset 10 are both working in a common working mode, the accessory microphone 250 collects ambient noise and outputs a first noise signal; the accessory microphone 250 sends the first noise signal to the accessory controller 240; the accessory controller 240 sends the first noise signal to the headset controller 330; the headset controller 330 receives the second noise signal output by the headset microphone 320 after collecting ambient noise; the headset controller 330 fuses the first noise signal and the second noise signal to output fused noise, and uses the fused noise for noise reduction. Since the microphone array composed of the headset microphone 320 and the accessory microphone 250 has a better ambient sound pickup effect, the ambient noise signal collected by the microphone array is used for noise reduction processing to improve the noise reduction performance.

In some embodiments, when the accessory metal contact 215 is electrically connected to the headset metal contact 301 on the TWS headset 300, the accessory power supply 260 is connected to the headset power supply 350. When the charge amount of the headset power supply 350 and the charge amount of the accessory power supply 260 meet the preset charging condition, the accessory power supply 260 is controlled to charge the headset power supply 350.
