OTG (On The Go, real-time data transmission) is the abbreviation of On-The-Go, is the technology developed in recent years, announced by USBImplementersForum on December 18, 2001, is mainly used in various devices or mobile devices (such as PDA, mobile Telephones, consumer devices) for data exchange, and change the inconvenience of data exchange between memory cards with multiple connectors of different standards among devices such as mobile phones, digital cameras, video cameras, and printers. Mobile phones with MicroUSB sockets and OTG functions have become more and more mainstream mobile phones. At present, the data transmission between OTG mobile phones and other storage devices has the following defects: U disks, Bluetooth headsets and other storage devices cannot be used directly on OTG mobile phones, and an OTG conversion line must be used when using them. U disks and other storage devices are relatively mobile phones. It is said that the volume is large, and then connected to the OTG conversion cable not only affects the appearance of the mobile phone, but also is inconvenient to use and carry.

Currently, mobile phones and the like have become necessities in people's work and life, and mobile phones with MicroUSB sockets and OTG functions are becoming more and more common. In view of the fact that people often carry their mobile phones around, refer to the introduction of the Bluetooth headset in the above background technology, and the technical problem of inconvenient and inefficient charging existing in the existing Bluetooth headset.

Optionally, earplugs are provided on the outside of the housing, and the earplugs can be fixedly connected to the housing by means of screws. A microphone and a switch are mounted on the printed circuit board, and a channel hole for the microphone to receive sound signals is opened at a position corresponding to the microphone on the housing. The LED light can be arranged on the top of the casing, and is electrically connected with the printed circuit board, so as to realize the indication of the power signal and the bluetooth working state signal.

In one embodiment of the present invention, the bluetooth headset also includes a MicroUSB cover, the first end of the MicroUSB cover is provided with a connection belt, and a raised structure is provided on the connection belt; the MicroUSB cover passes through the The protruding structure snaps into the through hole of the housing and connects with the housing; the second end of the MicroUSB cover is a cover-shaped structure. As shown in Figure 2, the plastic lower shell is provided with a through hole, the MicroUSB cover includes a cover-shaped structure protection cover inserted into the housing, and is arranged on the cover-shaped structure protection cover and connected to the The through hole of the plastic lower shell is clamped with the connecting strip. The connection strip is in the form of a strip, which extends along the direction of the connection between the MicroUSB device and the printed circuit board. A place where the connection belt is away from the protective cover of the cover-shaped structure has a protruding structure, and the protruding structure is engaged with the through hole of the plastic lower case. The MicroUSB male head is at the bottom of the fuselage, and the outside is covered by the USB cover. When charging is required, the MicroUSB male head can be exposed by directly pulling out the USB plug. The housing and the MicroUSB cover can be in a plug-in structure, so as to realize the protection of the MicroUSB device, and cooperate with the housing to ensure the consistency of product appearance. When the MicroUSB device is not used to charge the Bluetooth headset, the MicroUSB cover is plugged into the housing, so that the MicroUSB device is incorporated into the protective cover of the cover structure to avoid damage to the MicroUSB device . When using the MicroUSB device to charge the Bluetooth headset, the socket of the MicroUSB cover is separated from the housing. Since the raised structure is engaged with the through hole of the plastic lower case, the MicroUSB The cover will not be completely separated from the casing, so as to prevent the loss of the MicroUSB cover and affect the next use.

Please refer to Fig. 5 and Fig. 6, both of which are structural schematic diagrams of the embodiment of the bluetooth earphone provided by the present invention. In one embodiment of the present utility model, the upper cover of the housing is provided with a control member; the control member includes a keycap and an encoder; the keycap is a cover-like structure; the keycap and the shell The upper cover of the body is fixedly connected; the encoder is located in the cavity formed by the keycap and the housing; the encoder is connected to the printed circuit board.

Optionally, the operating member is configured to, when the keycap is pressed, the inner surface of the keycap touch the encoder to generate a first electrical signal, and the first electrical signal is used to indicate that the printing The circuit board executes one of starting up, shutting down, pairing, turning on the smart voice function, and turning off the smart voice function. Specifically, the encoder is provided with a DOM chip (dome), the user presses the DOM chip to trigger the DOM chip, and the DOM chip contacts with the contact to generate a first electrical signal. The printed circuit board performs different operation functions according to the properties of the first electrical signal.

For example, when the Bluetooth headset is in the off state, press and hold the button for 3 seconds, the first electrical signal is a power-on signal, instructing the printed circuit board to perform a power-on operation. At this time, the LED light guide will gradually light up in blue. Put on the earphones, and you can hear the voice prompt of "power on".

For another example, in the power-on/listening/music state, press and hold for 3s, the first electrical signal is a shutdown signal, instructing the printed circuit board to perform a shutdown operation. At this time, the LED light guide will gradually dim. Put on the earphone, you can hear the voice prompt of "power off".

For another example, in the off state, press and hold for 7s, the first point signal is the pairing signal, the Bluetooth headset enters the pairing mode, the color of the light guide will flash alternately, if you have already put on the headset, you can hear "waiting for connection" voice prompts.

For another example, after the headset is connected to the mobile phone, press and hold for 1 second, the first point signal is the signal of the intelligent voice function, and after hearing the voice prompt of "Bee", let go, and the intelligent voice can be activated.

Optionally, the control member is used for, when the keycap is rotated, the inner surface of the keycap drives the encoder to rotate; The device is in electrical contact to generate a second electrical signal, and the second electrical signal is used to instruct the printed circuit board to perform a volume adjustment operation.
