響装置。[Claim for Utility Model Registration] In a fish finder that detects a school of fish using a received echo signal obtained by transmitting an ultrasonic pulse and receiving a reflected wave, the received echo signal is converted into sound and the sound is converted into sound. Accordingly, there is provided an acoustic device for a fish finder that notifies the presence of a school of fish, comprising the steps of: (a) changing the tone of the sound to a higher value as time elapses based on the transmission timing signal for the transmission of the received echo signal; (b) converting the received echo signal into an acoustic modulation signal in which the timbre of the acoustic signal is sequentially changed to a lower value with the passage of time with reference to the transmission timing signal; A low-temperature depth means; and c. a high-low switching means for outputting an output obtained by switching to either the high-temperature depth means or the low-temperature sound means as a signal for the notification. An acoustic device for a fish finder, characterized in that it can detect schools of fish at any depth using a highly sensitive tone band.
