WOOFER EARPHONE HAVING AN AIR FLOWING STRUCTURE

摘要

The present invention relates to woofer earpieces having an air flow structure. The woofer earpieces include: an earpiece casing which has a hollow structure with a shaft tube unit formed on the lower part; an woofer unit which is arranged on the inner upper end of the earpiece casing; a speaker unit which is arranged on the inner lower end of the earpiece casing to be spaced apart from the woofer unit; an ear cushion having a cushion body having a hollow structure with an open upper surface, a through-hole which is formed on the center part of the cushion body to be coupled to the shaft tube unit on the lower part of the earpiece casing, and one or more vertical air flow through-holes formed between the outer periphery of the cushion body and the through-hole; and a cable outlet which is connected to the earpiece casing and stores electrical wire cables electrically connected to the woofer unit and the speaker unit individually. The woofer earpieces form air flow through-holes on the cushion to reduce the burden of the sound pressure on the eardrums when the earpieces are used for an extended period and provide a weight plate having a first resonant frequency (F0) value in the range of 50 to 100 Hz, thereby changing vibration effects to woofer effects during an operation.
