The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1, the utility model discloses a bluetooth headset of making an uproar falls based on electric capacity sensing gesture control, including falling bluetooth chip 1, microphone 2, connecting in loudspeaker 3 of falling bluetooth chip 1 of making an uproar, connecting in the electric capacity sensor 4 of falling bluetooth chip 1 of making an uproar.
The noise reduction bluetooth chip 1 receives and transmits a bluetooth signal of an external connection device (e.g., a mobile phone or a computer) through a bluetooth antenna. After receiving the gesture, the capacitive sensor 4 recognizes the gesture, calculates out the inverse sound wave through an internal data processor, and transmits the signal to the noise reduction Bluetooth chip 1. The noise reduction Bluetooth chip 1 controls the generation of a noise reduction signal and plays the noise reduction signal through a loudspeaker 3 to realize the noise reduction effect.
The microphone 2 is connected to the noise reduction Bluetooth chip 1, converts the received voice signal into a digital signal, and transmits the digital signal to the noise reduction Bluetooth chip 1, wherein the digital signal also comprises a noise signal. The noise reduction Bluetooth chip 1 identifies the digital signal and converts the digital signal into an analog signal, when the noise reduction function is started, the noise reduction Bluetooth chip 1 generates a noise reduction signal, the noise reduction signal and the analog signal are played through the loudspeaker 3, and the noise signal received by the microphone 2 is offset; when the noise reduction function is closed, the noise reduction Bluetooth chip 1 plays an analog signal through the loudspeaker 3, and a noise reduction signal is not generated.
The noise reduction signal generated by the noise reduction Bluetooth chip 1 and the noise signal received by the microphone 2 are in opposite phases, and the noise signal can be offset by the noise reduction signal.
The loudspeaker 3 is connected with the noise reduction Bluetooth chip 1 and is used for receiving the noise reduction signal sent by the noise reduction Bluetooth chip 1 and playing an analog signal and the noise reduction signal when the noise reduction function is started; when the noise reduction function is closed, the method is used for playing the analog signal.
The noise reduction Bluetooth chip 1 is connected with the capacitive sensor 4, the capacitive sensor 4 can be used for sensing a gesture preset by a user and generating a signal, the noise reduction Bluetooth chip 1 generates a noise reduction signal after receiving the signal of the capacitive sensor 4 and starts a noise reduction function of the noise reduction Bluetooth headset, the noise reduction signal is played through the loudspeaker 3, and the noise signal received by the noise reduction Bluetooth headset is offset; when the noise reduction function is started, the noise reduction function is closed after the signal of the capacitive sensor 4 is received, and the noise reduction signal is not generated any more.
