Wristwatch and method applicable to wristwatch for controlling magnitude of short distance communication signals

Abstract

A wristwatch and a method applicable to a wristwatch for controlling the magnitude of short distance communication signals are provided. A short distance communication module is disposed inside the wristwatch, and therefore short distance communication is carried out in the wristwatch. Also, an amplifier is deployed in the wristwatch, thereby carrying out enhancing the magnitude of the short distance communication signals. The magnitude of the short distance communication signals can also increase or decrease through user operations. In another aspect, a magnetic field isolating layer is disposed inside a housing of the wristwatch. The magnetic field isolating layer can reduce interference caused by the housing or other components of the wristwatch, and thus can enhance the magnitude of the short distance communication signals and extend the sensing distance.
