The embodiment of the present application relates to a method, device, speaker and storage medium for balancing the vibration of a speaker. The method includes: acquiring the parameter value of the cavity environment parameter of the speaker, and determining whether the vibration amplitude of the diaphragm of the speaker reaches The set upper limit is reached, and then the vibration of the diaphragm is balanced according to whether the vibration amplitude of the diaphragm reaches the set upper limit. Through the above method, the vibration of the diaphragm of the loudspeaker can be balanced, and the amplitude of the auxiliary diaphragm can reach the upper limit, so as to keep the vibration of the diaphragm in place and improve the smoothness of the operation of the loudspeaker.

The invention belongs to the technical field of clothing treatment, and aims to solve the problem that the installation position of the counterweight on the outer tub of the existing clothing treatment equipment is limited. To this end, the present invention provides a clothes treating apparatus, the clothes treating apparatus includes a box body, an outer tub and a shock absorber, the clothes treating apparatus further includes a weight member disposed on the outer tub and a weight member disposed on the outer tub The mounting member is connected to the box body through the shock absorber. In the present invention, the installation member connected with the shock absorber is arranged on the counterweight member, so as to avoid the interference between the counterweight member and the shock absorber in the structural arrangement of the laundry treatment device, thereby avoiding the occurrence of interference caused by the shock absorber. The installation position of the counterweight member cannot be installed due to the inability to install the counterweight member, which provides more flexibility for the installation and arrangement of the counterweight member, and at the same time, it can also facilitate the installation of the counterweight member to a certain extent and improve the assembly efficiency.

The invention belongs to the technical field of laundry processing equipment, and aims to solve the problem that in the existing laundry processing equipment, installing a counterweight on an outer cylinder results in a limited installation position of an installation member for installing the outer cylinder. To this end, the present invention provides a laundry processing device, which includes a box body and an outer cylinder, and the laundry treatment equipment also includes a counterweight member arranged on the outer tube and a connecting link between the counterweight member and the box body. Install components. In the present invention, by installing the installation member on the counterweight member of the drum, the interference between the installation member and the counterweight member in the structural arrangement of the laundry processing equipment is avoided, so that the installation position of the installation member will not be affected by the counterweight configuration. The limitation of the installation position of the components improves the flexibility of the arrangement of the installation components, and at the same time facilitates the installation of the counterweight components to a certain extent, avoiding the situation that the installation space of the counterweight components is insufficient.
