Abstract: A touch Bluetooth headset includes a housing, a touchpad, a main board, a Bluetooth antenna, a first thimble and a second thimble. The touchpad is a flexible touchpad, the main board and the touchpad are opposite and fixed on the housing, and the touchpad is provided with a plurality of metal contacts. The first thimble and the second thimble have one end fixed to the main board and other end extending toward the touchpad and abutting against the metal contacts. The Bluetooth antenna is laid on the touchpad and connected to the metal contacts. The touch Bluetooth headset may be designed to be more miniaturized; additionally, an additional Bluetooth antenna is added in the touchpad and the Bluetooth antenna is jacked up by the above thimbles, which reduces the electromagnetic shielding, thereby the micro Bluetooth headset has a better signal transmission distance.

Abstract: A method comprises: collecting an input audio signal; performing frequency-division processing on the input audio signal, extracting a high-frequency signal and a low-frequency signal to transmit respectively, and reserving one path of original audio signal; performing dynamic gain processing on the low-frequency signal adopting an Automatic Gain Control (AGC) algorithm, and performing low-pass filtering enhancement processing on the original audio signal adopting a static low-frequency enhancement algorithm; and subjecting the high-frequency signal, the processed low-frequency signal and the processed original audio signal to weighted summation to obtain a final output audio signal, the weight coefficients of the high frequency signal, the processed low-frequency signal and the processed original audio signal being a, b and c respectively, where the values of a, b and c range from 0 to 1, and a+b+c=1.
