摘要： A speaker system according to the present invention comprises a cabinet (10), a speaker unit (11), a first parting board (12), a drone cone (13), an adsorption member (14), a second parting board (15), a backboard (16), a variable mechanism (17), and a port (18). A sound pressure generated by the speaker unit (11) causes a pressure variation in a second chamber (R12) via the drone cone (13). The adsorption member (14) with an effect of physical adsorption is operable to suppress the pressure variation. Furthermore, by displacing the diaphragm (171), the variable mechanism (17) is operable to reduce a pressure variation of a direct current component, which is caused by variations in ambient temperature or atmospheric pressure of the speaker system.

摘要： A piezoelectric speaker includes: a chassis having a wall surface including an opening; a plurality of diaphragms including at least a first piezoelectric diaphragm and second piezoelectric diaphragms which vibrate in phases opposite to each other when a voltage is applied; and a joint member which connects the first and second piezoelectric diaphragms in a positional relationship such that the diaphragms are located at positions different from each other in a thickness direction. One of the diaphragms is provided, in the opening of the chassis, to have one surface facing an outside of the chassis and another surface facing an inside of the chassis. The diaphragm functions as a radiation plate which radiates a sound wave by vibrating at an amplitude generated by synthesizing amplitudes of the first and second piezoelectric diaphragms.
