PROBLEM TO BE SOLVED: To solve the problem that an electronic element such as a magnetic circuit or network element is thermally affected to deteriorate the performance of a speaker system. SOLUTION: The speaker system has a magnetic circuit 10 forming a magnetic gap, a vibrating body 20 including a voice coil 21 disposed in the magnetic gap, and a frame 30 which has a magnetic circuit storage part 30A where the magnetic circuit 10 is stored and supports the vibrating body 20, and the frame 30 has a space M on which back pressure, originating from vibrations of the vibrating body 20, operates in the frame and also has a communication hole 30s1, communicating with the space M, formed opposite the electronic element 32 mounted on the frame 30.
