Each of the two adjacent card walls 12 cooperates to define a spacing groove 13. The seat body 11 has a ring-shaped wall portion 111 having a hollow annular shape, and a shoulder portion 112 projecting radially outward from the ring wall portion 111. Each of the card walls 12 has an extending portion 121 extending upward from the ring wall portion 111, and a flange portion 122 projecting outwardly from the tip end of the extending portion 121. The base 1 is made of a metal material for the purpose of increasing strength, but may be made of a plastic material in practice, and is not limited to this embodiment.

The lining 2 is made of a flexible material and has an outer lining wall 21 which is annularly wound around the center line L and is tightly fitted on the outside of the extending portions 121, and is annularly wound around the center line. L and a lining wall 22 spaced apart from the center of the card wall 12, and a plurality of connecting ribs 23 which are spaced apart from each other and which are respectively spaced apart from the lining wall 22 and the outer lining wall 21, respectively. The top and bottom edges of the outer liner wall 21 are respectively blocked by the flange portions 122 and the shoulder portions 112, and are restricted between the flange portions 122 and the shoulder portions 112. The inner liner wall 22 defines a sound chamber 221 having an annular projection 222 that projects radially from the inner wall surface. By the associated support of the connecting ribs 23, the elasticity of the inner liner wall 22 and the outer liner wall 21 relative to each other can be provided. Of course, the number of the connecting ribs 23 can be two, three or more, and the number can be increased or decreased according to the required supporting force.

The base 3 is made of a plastic material and has a bottom wall 31 that closes the lower opening of the sound chamber 221, and a sleeve extending upward from the periphery of the bottom wall 31 and tightly fitting around the center line L. The peripheral wall 32 of the outer wall of the wall 22. The peripheral wall 32 has a plurality of fitting grooves 321 which are spaced apart from each other and which are respectively spanned by the connecting ribs 23.

The head 4 includes a body 41 that fits tightly into the liner wall 22 and closes the opening above the chamber 221, and a shield 42 that covers the periphery of the top of the body 41. The body 41 has an annular recess 411 which is recessed on the outer peripheral surface and is correspondingly embedded in the annular protrusion 222. The annular recess 411 allows the body 41 to be more stably embedded in the inner liner wall 22 .
