  • Publication number: 20190320265
    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.
