The present disclosure relates to a speaker cabinet for electronic device, which is disposed in an electronic device and comprises a cabinet body, two first fixing structures, two dampers, and two second fixing structures. The damper is disposed on two side surfaces of the cabinet body through the two first fixing structures and fixed on the electronic device through the two second fixing structures for fixing the cabinet body in the electronic device. The cabinet speaker according to the present disclosure adopts only two fixing structures to fix the cabinet body to the electronic device. The damper is also used for mitigating the vibrations generated by the cabinet body. In addition, the two fixing structures are used for supporting the damper for avoiding inclination of the cabinet body towards an unpredictable direction and colliding the housing of the electronic device and its internal components.
