Abstract

The invention discloses a Bluetooth earphone which includes a headphone, a microphone, a battery power supply module, an antenna, a Bluetooth module and an analog switch; the antenna is connected with the Bluetooth module; the analog switch is a monopole double throw switch; the first output end of the Bluetooth module is connected with the input signal end IN of the analog switch; the second output end of the Bluetooth module is connected with the output signal selection COM end of the analog switch; the first control end NO and the second control end NC of the analog switch are respectively connected with the headphone; one output end of the battery power supply module is connected with the power supply end V+ of the analog switch; the other output end is connected with the power supply end of the Bluetooth module. The Bluetooth earphone can give an alarm and has the alarming effect when the mobile phone of the user is disconnected with the Bluetooth earphone.

Description

technical field [0001] The invention relates to a wireless mobile terminal, in particular to a bluetooth earphone with an alarm function. Background technique [0002] Bluetooth technology is a short-range radio technology and an open unified standard specification for global voice and data wireless transmission. It can replace data cables and enable low-power, low-cost, short-distance wireless connections between any compatible portable and fixed devices. Based on this technology, computers and peripherals, mobile stations and computers, and home appliances installed separately within a short distance can be wirelessly connected to each other to achieve two-way and real-time communication, and circuit modules that implement Bluetooth have also been widely distributed. At present, electronic information products based on bluetooth technology are constantly being pushed to the market, and products with bluetooth functions are adding "wireless" shortcuts to our lives.
