DETAILED DESCRIPTION
[0040] The application will be further described in detail below with reference to the accompanying drawings.
[0041] The embodiment of the application discloses a multifunctional TWS earphone, which comprises an earphone body 1 and a charging box 2 used for charging the earphone body 1.
[0042] Referring to Figures 1 to 5 , the charging box 2 comprises a cover body 22, a box body 21, a sound collecting piece 3, an audio signal transmission interface 4, a volume adjustment key 6, a power key 7 and a control module 5. The cover body 22 is hinged to the box body 21, and the sound collecting piece 3, the audio signal transmission interface 4, the volume adjustment key 6, the power key 7 and the control module 5 are all arranged on the box body 21.
[0043] Referring to Figures 1 to 2 , the sound collecting piece 3 is arranged on a bump 212 at the top of the box body 21 and can collect the ambient sound signals around the charging box 2. When it is needed to collect sound by using the sound collecting piece 3, the sound collecting piece 3 can be placed near a sound source, such as near a television or near a person who is talking. The sound collecting piece 3 can be a microphone. The audio signal transmission interface 4 is arranged on one side of the box body 21, and a user can connect an audio output interface of a sound source and the audio signal transmission interface 4 by using a data line, so as to transmit the audio signals of the sound source to the charging box 2. When the transmission mode is adopted, the user can hear the sound of the sound source more clearly because there is no interference of other noises around the charging box 2. Specifically, the audio signal transmission interface 4 can be an audio interface, a type-c interface or a lightning interface.
[0044] Referring to Figures 4 to 6 , a first input end of the control module 5 is connected with an output end of the sound collecting piece 3 to receive the ambient sound signals around the charging box 2, and a second input end of the control module 5 is connected with an output end of the audio signal transmission interface 4 to receive the audio signals output by the audio signal transmission interface 4, so that the control module 5 can receive and process the audio signals collected by the sound collecting piece 3 and / or the audio signal transmission interface 4. An output end of the control module 5 is in wireless communication connection with an input end of the earphone body 1, so as to wirelessly transmit the ambient sound signals around the charging box 2 received by the sound collecting piece 3 and the external audio signals of the charging box 2 received by the audio signal transmission interface 4 to the earphone.
[0045] Referring to Figures 1 to 2 , in order to facilitate the use of the user, the volume adjustment key 6 is arranged at the front end of the box body 21, that is, the end of the box body 21 away from the hinge position of the box body 21 and the cover 22. The output end of the volume adjustment key 6 is connected with the third input end of the control module 5. The power key 7 is arranged on the protrusion 212 of the top of the box body 21, and the protrusion 212 can be inserted into the key through slot 221 of the cover 22, so that the power key 7 and the sound collecting piece 3 can be exposed to the cover 22, and the height of the power key 7 and the sound collecting piece 3 is basically flat with the surface of the cover 22. In some embodiments, a soft layer 222 can be arranged inside the key through slot 221, so that the power key 7 is blocked but the user can still press the power key 7 by pressing the soft layer 222. The soft layer 222 can be provided with a pickup hole in communication with the pickup port of the sound collecting piece 3.
[0046] Referring to Figures 1 to 3 , in the charging box 2, the cover 22 is hinged to the box body 21. The top of the box body 21 has a cavity 211 for accommodating the earphone body 1, and the cover 22 can close the cavity 211 at the top end of the box body 21 to prevent the earphone body 1 from falling out. The box body 21 includes an upper shell 213 and a lower shell 214 detachably connected with the upper shell 213. The edge of the lower shell 214 is provided with a notch slot 215, the cover 22 is protrudingly formed with a hinge part 223, the hinge part 223 extends into the notch slot 215, and the two sides of the hinge part 223 are protrudingly formed with hinge ears rotatably connected with the inner wall of the notch slot 215. The side of the hinge part 223 close to the inside of the box body 21 is provided with a limiting block 2231, and the upper shell 213 of the box body 21 has a limiting slot 2131 for the limiting block 2231 of the hinge part 223 to extend into. When the cover 22 is in the state of closing the box body 21, the limiting block 2231 extends into the limiting slot 2131, and the groove wall of the limiting slot 2131 is in close contact with the surface of the limiting block 2231, so that the limiting slot 2131 limits the limiting block 2231, thereby preventing the cover 22 from moving left and right by itself.
[0047] The specific embodiment is only an explanation of the utility model, and is not a limitation of the utility model. Those skilled in the art can make modifications to the embodiment without creative contribution after reading the specification, but as long as it is within the scope of the claims of the utility model, it is protected by the patent law.
