Title:
HEARABLE DEVICE AND HEARABLE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/033167
Kind Code:
A1
Abstract:
A hearable device (10) comprises a speaker (SP), a temperature detection circuit (20), an arithmetic circuit (31), a control circuit (32), an RF circuit (34), and an antenna (ANT). The temperature detection circuit (20) comprises a thermistor (21) and generates divided voltage measurement data according to the temperature of a member worn on the ear. The arithmetic circuit (31) detects the temperature from the divided voltage measurement data. The control circuit (32) uses a temporal change in temperature to generate off-information indicating that the device was removed from the ear. The RF circuit (34) transmits the off-information through the antenna (ANT) to the outside.
