Adjustable capacitor and electronic apparatus

An adjustable capacitor, comprising a base substrate and at least one capacitor unit on the base substrate, wherein each of the at least one capacitor unit comprises a first plate, a second plate and a first connecting arm;

• the first plate and the first connecting arm are on the base substrate;
• one end of the second plate is connected to the first connecting arm, the second plate and the first plate are opposite to each other, and a certain distance is between the second plate and the first plate;
• wherein the second plate is connected to the first connecting arm through a first elastic component;
• the first elastic component is configured to deform in response to that an operating environment reaches a specific temperature, such that an area of a region, where orthographic projections of the first plate and the second plate on the base substrates overlap each other, is changed;
• and/or
• the capacitor unit further comprises a second connecting arm on the base substrate;
• one end of the first plate is connected to the second connecting arm through a second elastic component, and a certain distance is between the first plate and the base substrate;
• the second elastic component is configured to deform in response to that the operating environment reaches the specific temperature, such that the area of the region, where the orthographic projections of the first plate and the second plate on the base substrate overlap each other, is changed,
• wherein the adjustable capacitor further comprises a package component;
• wherein the package component and the base substrate are opposite to each other, to define an accommodating space, and the capacitor unit is packaged in the accommodating space, and
• the adjustable capacitor further comprises a temperature control component on a side of the package component away from the base substrate, wherein the temperature control component is opposite to the at least one capacitor unit.
