PROBLEM TO BE SOLVED: To obtain a small sized light weight speaker system where a low pitch sound is reproduced excellently. SOLUTION: The speaker system is provided with a speaker 3 mounted on a baffle plate in front of a speaker box 1, an air-tight chamber 21 that is placed at a position corresponding to the speaker 3 on a rear side in the inside of the speaker box 1, a vibrating body 23 arranged via a moving body 22 which is placed on the speaker side of the air-tight chamber 21 and generates a reaction in opposite direction to the sound emission direction by using the reaction opposite to the sound emission direction of the speaker 3 as a drive force, and an air-tight space 20 formed to the speaker 3, and the air-tight chamber 21 and the air-tight space 20 are connected by a soft pipe 24.
