A woofer speaker is provided, comprising a woofer speaker monomer, a first sealing pad, a second sealing pad and a shell. The first sealing pad is fixed closely with the outer edge of the shell; the woofer speaker monomer is fixed and sealed within the shell by the first sealing pad, and the second sealing pad is located between the woofer speaker monomer and the shell; a sound hole is provided on the shell at the position where the woofer speaker is fixed, and the shape and size of the sound hole correspond to those of the woofer speaker; and the terminal installation plane fixed with the woofer speaker is the rear cover of the woofer speaker, and the terminal installation plane together with the shell forms the rear sound cavity of the woofer speaker through the first sealing pad. The cavity of the woofer speaker provided by the invention and the installation terminal applying the woofer speaker resolve the rear cover vibration problem of ultra-thin woofer speakers. |
