Abstract

The present invention relates to a magnetic controlled Bluetooth device and more particularly to a magnetic controlled Bluetooth speaker. The magnetic controlled Bluetooth device comprises a magnetic unit and a magnetic sensor. As another magnetic unit approaches the magnetic sensor of the magnetic controlled Bluetooth device, the magnetic sensor varies its output voltage in response to the magnetic field of another magnet. Thus, the magnetic controlled Bluetooth device can be turned on to execute a Bluetooth pairing process. Further, the magnetic unit of the magnetic controlled Bluetooth device can be used to approaches another magnetic sensor of another magnetic controlled Bluetooth device to turn on another magnetic controlled Bluetooth device.

Claims

1. A magnetic controlled Bluetooth device, comprising:

a magnetic unit;

a magnetic sensor configured to sense a magnetic force to generate a triggering signal;

a control unit electronically connected to said magnetic sensor, said control unit including a Bluetooth chip, wherein said control unit is configured to turn on said Bluetooth chip to execute a Bluetooth pairing process, as said control unit receives said triggering signal from said magnetic sensor, wherein said magnetic sensor comprises an output end, said control unit comprises a sensing end, and said output end of said magnetic sensor is connected to said sensing end of said control unit; and

at least one power supply unit connected to said control unit and said magnetic sensor, wherein said power supply unit is electronically connected to said output end of said magnetic sensor and said sensing end of said control unit via at least one impedance unit connected in series from said power supply unit to said magnetic sensor and said control unit; and

electrically connected to said control unit and said magnetic sensor to supply a voltage power to said magnetic sensor and said control unit.

2. The magnetic controlled Bluetooth device according to claim 1, wherein said magnetic sensor is a Hall sensor.
