Ultrasonic dog repeller with two ultrasonic emitters

Abstract

An ultrasonic dog repeller with two ultrasonic emitters comprises a housing (1) formed with a part cavity, a front support (2) clamped in the part cavity, a main board (3) clamped on the front support (2) and provided with a battery (4), and an ultrasonic head clamped on the front support (2), provided with a pair of ultrasonic emitters (5) capable of emitting in-phase ultrasonic sounds, and electrically connected to the main board (3). According to the ultrasonic dog repeller with two ultrasonic emitters, ultrasonic waves emitted by the two ultrasonic emitters (5) are superimposed, so that compared with the prior art, the ultrasonic waves can be transmitted farther by users, and the two ultrasonic emitters (5) are protected from being burnt out.
