The screen 2 is made of plastic such as polypropylene and has a curved shape convex forward. Further, the main body 20 of the screen 2 is formed (colored) in white, milky white, translucent, etc., so that the light from the projector 4 from the rear side can be transmitted to the front side and projected. .

As will be described later, as the acoustic characteristics of the speaker (2), material physical properties such as Young's modulus E, density σ, inelastic modulus σ/E, and internal loss η are required. , suitable for diaphragm due to internal loss characteristics. In addition, as the screen 2, it is also possible to adopt a mode in which one surface of a transparent acrylic plate is painted milky white, and the light transmitting portion instead of the through holes 21 is not painted.

The screen 2 of this embodiment also functions as a speaker 3 that transmits sound over a wide range from the entire surface of the screen 2 by connecting a vibrating device 30 . A loudspeaker 3 emits a cry of a fierce beast (hostile animal) projected on the screen 2, a warning sound, or the like. In this way, by emitting sound from the main body of the screen 2, it seems that the ferocious beast projected on the screen 2 is barking or barking. Note that it is also possible to mount the speaker 3 separately from the screen 2 .

The projector 4 is a laser projector that emits laser light, and projects a ferocious animal from behind onto the screen 2 when a vermin is detected by the sensor 10 based on an instruction from the controller (5).

Furthermore, the vermin repelling device 1 preferably further includes an omnidirectional speaker 6 in addition to the speaker 3, as shown in FIG. The omnidirectional speaker 6 is mounted on the casing of the vermin repelling device 1 and emits sound in all directions.

The type identification function unit 51 identifies the type of vermin based on the vermin information obtained by the sensor 10 . Then, the controller 5 changes the kind of wild animal projected on the screen 2 according to the kind of the identified vermin. For example, when the sensor 10 detects a moving object, an image of a wild animal barking, such as a lion, a tiger, and a wolf (hunting dog), is projected onto the rear-projection screen 2 (also used as the speaker 3) by the projector 4 together with the sound. The reproduction is designed to carry out the intimidation.

The distance identification function unit 52 identifies the distance to the vermin based on the vermin information obtained by the sensor 10 . The controller 5 changes the volume of the speaker 3 according to the distance from the identified vermin. For example, when the vermin is relatively far away, it is preferable to make the sound softer and gradually increase the sound as it approaches, thereby enhancing the intimidating effect. In addition, it is also preferable to change the projected state of the ferocious beast and the sound it emits according to the distance from the vermin.

The direction identification function unit 53 identifies the direction of the vermin based on the vermin information obtained by the sensor 10 . Then, the controller 5 changes the orientation of the entire vermin repelling device 1 according to the direction of the identified vermin. For example, if the vermin moves from right to left, the screen 2 (also used as the speaker 3) of the vermin repelling device 1 will also change its direction from right to left so as to follow it, so that it always faces the vermin. It is preferable that
