The utility model discloses an earthquake-proof and fall-proof power amplifier, comprising a power amplifier本体, an inner protective shell and an outer protective shell. The outer protective shell is provided with an arc-shaped accommodating槽at each of the eight corner positions of the outer protective shell, and a shock-absorbing sponge is placed in the arc-shaped accommodating槽. The outer surface of the shock-absorbing sponge is wrapped with a layer of rubber垫. Three pairs of high-efficiency seismic resistance机构are arranged in the interlayer between the outer protective shell and the inner protective shell in the up and down directions. One pair of high-efficiency seismic resistance机构are arranged in the interlayer between the outer protective shell and the inner protective shell in the left and right directions. Each pair of high-efficiency seismic resistance机构comprises two seismic resistance器with the same structure but independent of each other. The seismic resistance器comprises a positioning support column, a positioning support sleeve, a transmission support摆杆, a vertical coil spring, a vertical inner spring, a guide pressure block and a horizontal pressure spring. The utility model guarantees the safety of the internal power amplifier and prolongs the service life.
