摘要 With a speaker according to the present invention, first space (20) enclosed by the surface of second edge (17) close to magnetic circuit body (10), suspension holder (18), the outer circumferential surface of voice coil body (12), magnetic circuit body (10), and frame (9) is airtight to the atmosphere outside the speaker, to make first space (20) function as an air suspension. Voice coil body (12) is supported with first edge (16) and second edge (17), and with the aid of the springiness of gas inside first space (20). Hence, an equivalent, low Young's modulus can be set to first edge (16) and second edge (17). Consequently, deformation of diaphragm (15) connected to first edge (16) is reduced during sound reproduction, thereby reducing disturbance in frequency response in the middle and high ranges.
