发明名称 EARPHONE VIA DRUMHEAD
摘要 A bowl-shaped cover (1) with a hole at the bottom replaces the cover with a sound hole of the conventional earphone, thus creating a constant space. The earphone sound vibrates the cover (1) by beating the inside of the cover (1) and then the vibration is transmitted to a rubber drumhead (vibrating membrane) (2) which is attached onto the cover (1). The rubber drumhead (vibrating membrane) (2) of the earphone works as a soft earmuff and makes wearing feel soft and comfortable. The present invention relates to the earphone that converts sound into vibration and also isolates sound.
