DETAILED DESCRIPTION
The disclosure, including the accompanying drawings, is illustrated by way of example and not by way of limitation. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one.
Referring to FIG. 1, an embodiment of a mobile phone 100 includes a main body 20 and an earphone 10.
Referring to FIG. 2 also, the earphone 10 includes an earplug 18 and an inserting portion 19 extending from the earplug portion 18. In one embodiment, a hole 142 is defined in a front surface of the earplug 18. The inserting portion 19 is substantially rectangular. A plurality of holes 162 are defined in a front surface of the inserting portion 19. A universal serial bus (USB) interface 11 is mounted on a rear surface of the inserting portion 19. In other embodiments, the configuration of the earplug 18 and the inserting portion 19 can be changed according to requirements.
Referring to FIG. 3, the main body 20 is substantially rectangular. A depressed portion 28 is defined in a top of the main body 20 for receiving the earplug 18. A mounting hole 29 is defined in a bottom of the depressed portion 28 for receiving the inserting portion 19. A cover 27 (FIG. 1) is rotatably mounted on the main body 20 for covering the earplug 18 when it is received in the depressed portion 28. A USB interface 21 is mounted on a sidewall bounding the mounting hole 29, corresponding to the USB interface 11.
Referring to FIG. 4, in assembly, the inserting portion 19 of the earphone 10 is inserted in the mounting hole 29 of the main body 20, and the earplug 18 is received in the depressed portion 28. At this time, the USB interface 11 of the earphone 10 is electrically connected to the USB interface 21 of the main body 20. The cover 27 is rotated to cover the earplug 18, so that the earphone 10 is retained to the main body 20.
Referring to FIG. 5, the earphone 10 further includes a USB audio module 12, a battery module 13, a speaker module 14, a BLUETOOTH module 15, a microphone module 16, and an antenna module 17. The speaker module 14 is connected to the USB interface 11 through the USB audio module 12, and connected to the microphone module 16 through the BLUETOOTH module 15. The hole 142 of the earplug 18 aligns with the speaker module 14, and the holes 162 of the inserting portion 19 align with the microphone module 16. The BLUETOOTH module 15 is connected to the USB interface 11 through the battery module 13. The antenna module 17 is connected to the BLUETOOTH module 15.
Referring to FIG. 6, the main body 20 further includes a USB audio module 22, a control module 23, a BLUETOOTH module 24, an antenna module 25, and a detecting module 26. The control module 23 is connected to the USB interface 21 through the USB audio module 22, connected to the USB interface 21 through the detecting module 26, and connected to the antenna module 25.
When the earphone 10 is inserted in the main body 20, the detecting module 26 detects that the USB interface 11 is electrically connected to the USB interface 21. The detecting module 26 sends a first control signal to the control module 23. The control module 23 controls the USB audio module 22 to work according to the first control signal. Therefore, the USB audio module 22 can communicate with the USB audio module 12 through the USB interfaces 11 and 21. Namely, the main body 20 can control the speaker module 14 through the USB audio modules 22 and 12. In this working state, the mobile phone 100 works as an ordinary mobile phone. Meanwhile, the battery module 13 is charged by power pins of the USB interfaces 11 and 12.
When the earphone 10 is pulled out from the main body 20, the detecting module 26 detects that the USB interface 11 is not electrically connected to the USB interface 21. The detecting module 26 sends a second control signal to the control module 23. The control module 23 controls the BLUETOOTH module 24 to work according to the second control signal. Therefore, the BLUETOOTH module 24 can communicate with the BLUETOOTH module 15 through the antenna modules 25 and 17. Namely, the main body 20 can control the speaker module 14 and the microphone module 16 through the BLUETOOTH modules 24 and 15. In this working state, the mobile phone 100 works as a BLUETOOTH mobile phone, the battery module 13 supplies power to the BLUETOOTH module 15. If the BLUETOOTH module 15 has no power to work, the earphone 10 can be inserted in the main body 20 allowing the battery module 13 to be charged by the power pins of the USB interfaces 11 and 21 again, which is very convenient.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and function of the embodiments, the disclosure is illustrative only, and changes may be made in details, especially in matters of shape, size, and arrangement of parts within the principles of the embodiments to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
