Problems solved by technology
As a result, usually the horns 81a and 81b are in an inoperable state
However, if the special anti-theft horn 82 is arranged, for example, in an inaccessible position in the engine room from the outside, the usual horn and the anti-theft special horn will become different systems.

Embodiment Construction
[0037] Hereinafter, a warning device for a vehicle according to an embodiment of the present invention will be described with reference to the drawings.
[0038] An alarm device 1 for a vehicle according to an embodiment of the present invention is a device that drives not only a siren but also an anti-theft alarm, such as figure 1 with figure 2 As shown, there is a woofer (LOW HORN, first horn) 41 that emits a low tone and a security horn (SECURITY HORN, a second horn) 42 that emits a high tone relatively. The woofer 41 is disposed near the grille opening 101 at the front end of the vehicle, etc., in order to satisfy the sound pressure required by law as a siren. In addition, the safety horn 42 is arranged at a position that is not easily accessible from the outside of the vehicle, specifically, inside the bumper 102 on the front side of the vehicle or the like. The security horn 42 emits an alarm sound when a theft is detected, and whistles together with the woofer 41 as...
