Abstract
An ultrasonic wave output device includes a plurality of ultrasonic wave output units, a hold unit, and a tubular unit. The plurality of ultrasonic wave output units output ultrasonic waves in a traveling direction set in advance in response to an input signal. The hold unit holds the plurality of ultrasonic wave output units. The tubular unit surrounds the plurality of ultrasonic wave output units in a direction orthogonal to the traveling direction. The tubular unit is connected to the hold unit.
Claims4
An ultrasonic wave output device comprising:
- a plurality of ultrasonic wave output units configured to output ultrasonic waves in a traveling direction set in advance in response to an input signal;
- a hold unit that holds the plurality of ultrasonic wave output units;
- and
- a tubular unit that surrounds the plurality of ultrasonic wave output units in a direction orthogonal to the traveling direction, and connected to the hold unit,
