An earphone with dual resonance tanks is provided to implement smooth air circulation and reduce power consumption by forming the dual resonance tanks. An earphone with dual resonance tanks includes a body(1), a speaker(2), a cushion member(3), first and second resonance tanks(A,B), and air inlets(13,14). The speaker is assembled inside the body, is connected with a code(15), and is received on a speaker receiver inside the body. The speaker receiver is an end of a protrusion part of the body. The cushion member is coupled to the exterior of the speaker. The first resonance tank is formed between the cushion member and the speaker. The second resonance tank is formed inside the body. The air inlets are formed at upper and lower parts of the speaker receiver. |
