Oscillator device and electronic instrument

An electronic instrument comprising:

• an oscillator device;
• and
• an oscillation driving unit that causes the oscillator device to output ultrasonic waves demodulated into sound waves of an audible zone,
• wherein the oscillator device comprises
• a plurality of piezoelectric vibrators of which each has an elastic member and a piezoelectric element attached to the elastic member, and
• a supporting member that supports the plurality of piezoelectric vibrators,
• wherein the supporting member has an opening, and
• wherein the plurality of piezoelectric vibrators are arranged in the opening along a first direction.

An electronic instrument comprising:

• an oscillator device;
• an oscillation driving unit that causes the oscillator device to output ultrasonic waves;
• an ultrasonic wave detection unit that detects sound waves having the same frequency as the ultrasonic waves;
• and
• a distance measurement unit that measures a distance to an object to be measured on the basis of the detected ultrasonic waves,
• wherein the oscillator device comprises
• a plurality of piezoelectric vibrators of which each has an elastic member and a piezoelectric element attached to the elastic member, and
• a supporting member that supports the plurality of piezoelectric vibrators,
• wherein the supporting member has an opening, and wherein the plurality of piezoelectric vibrators are arranged in the opening along a first direction.
