Title:
SIGNAL TRANSCEIVING APPARATUS, ELECTRONIC DEVICE, WEARABLE DEVICE, AND WIRELESS EARPHONE
Document Type and Number:
WIPO Patent Application WO/2022/134901
Kind Code:
A1
Abstract:
The present application relates to a signal transceiving apparatus, an electronic device, a wearable device, and a wireless earphone. The signal transceiving apparatus comprises a first touch sensing unit and a second touch sensing unit. The first touch sensing unit comprises a first sensing body, a first touch sensing module, a low-pass filter circuit, a wireless transmission module, and a high-pass filter circuit The first sensing body is a conductive body, and is used for detecting a touch operation; the first sensing body is provided with a common end, and the first touch sensing module is connected to the common end by means of the low-pass filter circuit. The wireless transmission module is connected to the common end by means of the high-pass filter circuit, and is configured to feed an excitation current to the first sensing body by means of the common end, thereby enabling the first sensing body to radiate a radio frequency signal. The second touch sensing unit comprises a second sensing body and a second touch sensing module; the second sensing body and the first sensing body are disposed at intervals and are electrically isolated from one another; and the second sensing body is used for detecting a touch operation. The foregoing signal transceiving apparatus can achieve the sharing of a wireless transmission function and a capacitive touch function.
