Abstract: A composite lock includes a lock control unit and a Bluetooth unit. The Bluetooth unit is connected to the lock control unit, and the Bluetooth unit controls the lock control unit according to a result of pairing and authentication with a handheld unit, so as to enable the composite lock to be in a locking state or an unlocking state.

Abstract: A non-contact control method and a non-contact control device are applied to a lock control device in a non-contact mode for manipulation. The non-contact control device includes a master control module and a slave control module. Both the master control module and the slave control module include a radio frequency identify (RFID) component and a Bluetooth component. In the master control module and the slave control module, the RFID component serves as first-layer authentication and unlocking and starts the Bluetooth component, and the Bluetooth component serves as second-layer authentication and unlocking and triggers a circuit control device. The master control module actively starts the slave control module and performs pairing and unlocking, so as to achieve a non-contact locking and control mode with low energy consumption and high security.

Abstract: A stereophonic wireless microphone includes a memory module, a sound signal receiving module, a CPU, a sound information processing module and a Bluetooth wireless communication module. The memory module saves accompaniment information. The sound signal receiving module receives at least one original sound signal inputted from exterior to generate a first sound signal. The CPU electrically connected to the memory module is for processing the accompaniment information. The sound information processing module, which is electrically connected to the CPU and the sound signal receiving module, generates sound information according to the first sound signal or the accompaniment information. The Bluetooth wireless communication module, which is electrically connected to the sound information processing module, generates a wireless signal according to the sound information generated by the sound information processing module.
