FEEDBACK TYPE WIRELESS EARPHONE

摘要

PURPOSE: A feedback type wireless earphone is provided to reduce the number of elements in comparison with the wireless earphone utilizing an RF signal or an infrared ray communication as well as to reduce the manufacturing cost. CONSTITUTION: A feedback type wireless earphone includes a transmission loop(100) and a wireless earphone body(200). The transmission loop(100) is provided with an earphone jack capable of inserting into the earphone jack of the electronic device for inducing the radio wave by using an induced electromagnetic force generated from the electrical audio signal outputted from the earphone jack of the electromagnetic device. The wireless earphone body(200) is manufactured in such a way that it does not appear outside when it is inserted into the ear. After the induced electrical audio signal is amplified, the amplified signal is converted into a sound wave through a vibration plate for transmitting to the user.
