Title:
PORTABLE THERMOELECTRIC GENERATOR FOR BATTERY OF WIRELESS EARPHONE
Document Type and Number:
WIPO Patent Application WO/2023/113189
Kind Code:
A1
Abstract:
The present invention relates to a portable thermoelectric generator for a battery of a wireless earphone. The essential technical point of the present invention is characterized in that a semiconductor leg set including a N-type and a P-type combined therein and a conductor ring pad including a metal material are integrated to form a thermoelectric generator, and the thermoelectric generator, corresponding to a kind of a power ring, is mounted on a wireless earphone. The thermoelectric generator assists a battery to be charged with current generated during movement of electrons (movement from a position having a high temperature to a position having a low temperature) due to a difference between the temperature of a user's body (a temperature of the surface coming in contact with the ear when inserted into the ear) and the temperature of the air, thereby extending the operational time of the wireless earphone.
