A headphone and an electronic device are provided. The headphone includes a gyroscope, which senses a bone conduction vibration and provides a quadrature error signal for reflecting the bone conduction vibration. Specifically, the headphone includes a transmission assembly that acts directly or indirectly on the gyroscope or an inertial measurement unit (IMU) including the gyroscope. The transmission assembly transmits the bone conduction vibration to the gyroscope to make the gyroscope strain, thereby causing the quadrature error signal of the gyroscope to change to detect the bone conduction vibration with sensitivity.

One of the main objects of the present invention is to provide a bone conduction microphone with simplified structure and easier manufacturing process. To achieve the above-mentioned objects, the present invention provides a bone conduction microphone, including: a housing; a circuit board opposite to the housing; and a vibration assembly locating between the housing and the circuit board. The vibration assembly includes a vibration membrane made of high temperature resistant dustproof breathable material, a weight fixed to the vibration membrane, and a first cavity formed between the vibration membrane and the circuit board. The bone conduction microphone further includes a pressure assembly locating between the vibration assembly and the circuit board for detecting a pressure change generated in the first cavity and converting the pressure change into an electrical signal.

An interactive system can utilize microtechnology (e.g., a micro-electromechanical system (MEMS)), such as miniaturized microphone (e.g., a bone-conducting microphone), audio output device, microprocessor, and signal conversion and propagation means to create a personal area network (PAN) for a user. The system can include a voice input device (e.g., worn on one or more teeth of the user) that outputs a near-field magnetic induction (NFMI) signal based on a whisper input by the user. The NFMI signal is either detected by the user's mobile device, or converted into a wireless signal (e.g., a Bluetooth RF signal) detectable by the user's mobile device, for receiving voice commands (e.g., to provide personal assistant services) via a designated application running on the mobile device.
