Correspondingly, the first cavity 111 and the second cavity 112 are divided into two ends of the housing 110 located in the “L” shape. For example, the first cavity 111 and the second cavity 112 may communicate at 90°. Of course, the first cavity 111 and the second cavity 112 may also communicate at an angle slightly less than 90° or communicate at an angle slightly greater than 90°, and accordingly, the shape of the housing 110 needs to be adjusted accordingly.

Of course, as an optional implementation manner, the shape of the housing 110 here is only schematic, and it can be understood that the housing 110 may also have other shapes.

The space utilization rate in the second cavity of the conventional earphone (corresponding to the rod portion of the conventional earphone) is low. Compared with the conventional earphone, in the earphone 100 of the embodiment of the present application, since the position of the first battery 130 is moved from the first cavity 111 to the second cavity 112 , the amount of electricity in the second cavity 112 can be reduced. The degree of waste of space can effectively utilize the internal space of the earphone 100 .

Optionally, in the case where the overall volume of the conventional earphone is the same as that of the earphone 100 in the embodiment of the present application, since the first battery 130 is removed from the first cavity 111, compared with the conventional earphone, in this There is more remaining space in the first cavity 111 of the earphone 100 in the application. Therefore, from the perspective of improving user experience, more structures can be added to the first cavity 111 to improve the function of the earphone 100 . For example, in an optional implementation manner, the speaker 140 may adopt a combination of a moving coil and a moving iron, so that the sound quality of the earphone 100 is better, and a better experience is provided for the user.

The battery of a conventional earphone generally shares a cavity with the speaker 140, and the space of the cavity is limited, resulting in a small battery and limited battery capacity, resulting in poor battery life of the conventional earphone.

In the embodiment of the present application, the volume of the second cavity 112 that can be used to accommodate the battery is greater than the volume of the first cavity 111 that can be used to accommodate the battery. That is, the second cavity 112 can be used for placing a battery with a larger capacity, thereby improving the overall battery life of the earphone 100 .

Optionally, the number of charging thimbles 180 may be two. The charging thimble 180 can charge the first battery 130 and the second battery 150 after the charging thimble 180 is in contact with an external power source (for example, the earphone 100 is put into a suitable charging box). In addition, the charging thimble 180 can also signally connect the earphone 100 and the charging box, so that the two communicate with each other. For those skilled in the art, the peripheral circuits of the charging thimble 180 are all in the prior art, and will not be repeated here.

In the embodiment of the present application, the charging thimble 180 is directly arranged on the main board 120, so that the charging thimble 180 does not need to be electrically connected to the main board 120 by means of a flexible circuit board, which can reduce the number of flexible circuit boards, save the internal stacking space of the earphone 100, and can Reducing costs can also simplify the internal stacking of the headset 100, greatly reducing the difficulty of installation and improving the efficiency of installation.

Optionally, referring to FIG. 4 , in some embodiments, the earphone 100 may further include an antenna 160, and the antenna 160 is electrically connected to the main board 120. In some optional implementations, the antenna 160 may adopt a flexible antenna. The antenna 160 is located in the second cavity 112 , and is attached to the inner wall of the casing 110 , and is located between the surface of the first battery 130 and the inner wall of the casing 110 . The antenna 160 and the first battery 130 share the second cavity 112 , which effectively saves the stacking space of the earphone 100 . In addition, the antenna 160 is arranged at a position close to the first battery 130, so that the antenna 160 can utilize the first battery 130 for radiation, thereby improving the transmission efficiency of the antenna 160.

Optionally, referring to FIG. 5 , in some embodiments, the headset 100 may further include a noise reduction microphone 170 and a call microphone 171 . The noise reduction microphone 170 and the call microphone 171 are both disposed on the main board 120 and electrically connected to the main board 120 .

In addition, when the two microphones are used in combination, they are used to implement the ENC (Environmental Noise Cancellation) noise reduction function. For those skilled in the art, it is the prior art that the combined use of two microphones to achieve ENC noise reduction will not be repeated here.

In this embodiment, the noise reduction microphone 170 is located in the first cavity 111 to ensure the quality of the sound that the user's calling object can hear. sound.

Users can control to play/pause music, answer/hang up calls, adjust volume and other operations by touching capacitive touch buttons. In this embodiment, correspondingly, the buttons 190 are electrically connected to the main board 120 and are enclosed by the casing 110 . Optionally, the button 190 may be disposed in the first cavity 111. The capacitive touch keys are connected to the main board 120 through a flexible circuit board.

When the key 190 is a capacitive touch key, a touch sensing area is further provided on the casing 110 at a position corresponding to the capacitive touch key, which is convenient for the user to operate. When the human skin touches the touch-sensing area, electric charges will move in the touch-sensing area, resulting in a change in the capacitance of the touch-sensing area. The change in the capacitance can lead to the generation of a control signal, and the control signal can cause the main board 120 to control the earphone 100 . It is worth noting that, for those skilled in the art, the peripheral circuits and specific control principles of the capacitive touch keys are all in the prior art, and will not be repeated here.

Optionally, the wearing detection module 200 may detect the wearing condition of the earphone 100 through the infrared detection principle. At this time, the wearing detection module 200 can be, for example, an infrared sensor. When the infrared sensor detects that the distance between an object and itself is less than the first detection threshold (for example, 5 cm), it is determined that the user is wearing the headset 100. When the infrared sensor detects that the distance between the object and itself is greater than the second detection threshold (for example, it is 8 cm), it is determined that the user is taking off the earphone 100.

Optionally, the wearing detection module 200 can also judge and detect the wearing condition of the earphone 100 through the principle of capacitive induction. At this time, the wearing detection module 200 may include a capacitance sensing area.

When the capacitive sensing area is in contact with the human body, the electric charge will move in the capacitive sensing area, resulting in a change in the capacitance of the capacitive sensing area. The change in the capacitance can lead to the generation of a control signal, and the control signal can cause the main board 120 to control the earphone 100 . For example, when the mainboard 120 judges that the user takes off the earphone 100 according to the change in the electric capacity, it can control the earphone 100 to pause playing music, and when the mainboard 120 judges that the user is wearing the earphone 100 according to the change in electric capacity, it can control the earphone 100 to start playing music.

Optionally, in order to improve the detection accuracy of the wearing detection module 200, the capacitive sensing area may be arranged in the first cavity 111 close to the human body or at the junction of the first cavity 111 and the second cavity 112.

It is worth pointing out that, for those skilled in the art, the peripheral circuits and specific control principles of the capacitive wearing detection module 200 are all in the prior art, and will not be repeated here.

Optionally, referring to FIG. 8 and FIG. 9 , the earphone 100 may further include an ear hook 210 connected to the housing 110 .
