The present application discloses a system for converting vibration to voice frequency wirelessly and a method thereof. By sensing a first vibration variation data and a voice frequency variation data of a vocal vibration part in a first sensing period, a voice frequency reference data is obtained from the voice frequency variation data and the first vibration result. A second vibration result is obtained at a second sensing period for converting to a voice frequency output signal, and the voice frequency output signal is used to output as a voice signal corresponding to the voice frequency various result. Thus, the present application provides a voice signal close to a human voice.

A throat headset system includes an element configured to be arranged at least partially around a user's neck, at least one microphone being connected to the element and configured to be in contact with a user's throat or neck skin when the headset is worn and connected wireless or by cable to the microphone and configured to be connected to a communication device, in a wireless manner or via a cable, and at least one earphone connected to the cable or in a wireless manner to a communication unit. The microphone is a microphone of the type that does not require power or electric energy of a power source for detecting sound waves.

A system for covert communication including a transmitter set at least one receiver set comprising an antenna, a battery and battery case, a signal receiving device, a signal conditioning device, a vibration disc and a housing wherein the antenna, the battery and battery case, the signal receiving device and signal conditioning device are contained within the housing.

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.

A bone conduction microphone is configured to convert vocal cord vibration into a sound signal. The bone conduction microphone includes a vibration collection unit configured to come into contact with a human body and collect vibration in a predetermined direction, which is included in the vocal cord vibration, and a switch configured to switch whether collection of the vibration in the predetermined direction is enabled. The switch is disposed on a side of the vibration collection unit, which is opposite to a side configured to come into contact with the human body, to allow a direction of an operation of switching whether collection of the vibration in the predetermined direction is enabled to be parallel to the predetermined direction.
