Abstract: The present invention provides a method for suppressing generation of hydrogen gas at the time when an ion concentration gradient is generated by a temperature responsive electrolyte. An electrolytic solution contains a temperature responsive electrolyte and an oxidation-reduction active species. The temperature responsive electrolyte is an electrolyte whose pKa varies according to the temperature. A power generating device performs power generation by using the electrolytic solution. The power generating device includes a positive electrode, a negative electrode, a heating mechanism, and a cooling mechanism. The positive electrode and the negative electrode are immersed in the electrolytic solution. The heating mechanism heats the electrolytic solution that is present in the vicinity of one of the positive electrode and the negative electrode. The cooling mechanism cools the electrolytic solution that is present in the vicinity of the other one of the positive electrode and the negative electrode.

Each of the speaker units has a diaphragm having two surfaces, and a driver unit for inputting an electrical signal and driving the diaphragm. Each of the sealed spaces has at least two boundary diaphragms. Each of the boundary diaphragms is one of the diaphragms, disposed so that a first one of the surfaces faces inside the sealed space and a second one of the surfaces faces outside the sealed space.

The boundary diaphragms driven outward and the boundary diaphragms driven inward are the same in number, and thereby a volume of the sealed space is kept constant.
