JP2002347516A - Adjustable horn device for automobile - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a horn device which determines a circumstance under which the horn device is used based on the running speed of an automobile to automatically adjust the tone and volume of the horn to be suitable to the range of alarming. SOLUTION: The device is linked with a running speed detection device to automatically determine the circumstance under which the horn device is used, thereby changing the tone and volume to be associated with the speed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a horn device which judges the situation at the time of use based on the traveling speed of an automobile and automatically changes the sound quality and volume to suit the warning range. 2. Description of the Related Art Conventionally, a horn device of an automobile always has a constant sound quality volume, and its setting is generally a very sharp sound that passes well so that it can be used even when driving at a high speed or in an emergency. When traveling at low speeds or when stopping, it is considered safe to judge that the range and distance of the warning target is also short and the degree of urgency is low. it is conceivable that. Often, horns are used to warn and alert other vehicles and people. However, there are usually many cases of sounding instead of a little greeting or a signal, and those who sounded are just going to use it with a light feeling, but those who received it touched the feeling, and there are many cases where they got caught and troubled, It has caused fights, injuries, and murders. The present invention has been invented to eliminate such disadvantages.At the time of stopping and running at low speeds, the sound of soft gentle sound quality is emitted at the lowest volume in the law instead of the strong high attitude sound quality, and the normal running sound The sound volume can cover the range that suits the speed. At high speeds, the sound is emitted at the maximum volume required by law with high sensitivity sound quality for emergency use. This will be described with reference to the system block diagram in the drawing. If the (5) operation selection switch installed in the driver's seat is selected to be "automatically variable", the (4) horn operation switch in the center of the steering wheel is operated. Then, the traveling speed detecting device mainly composed of a sensor or the like sends a detection signal to the controller unit mainly composed of electronic components. (3) The controller unit automatically determines the state of use based on the signal, and the internal transmitting device sends a sound source signal to the (2) horn device to emit a horn sound. In this manner, by installing the device that automatically changes the volume and the sound quality in conjunction with the speed, it is possible to both be gentle to the other party and to have both functions as a warning and a warning, which are the original functions. In addition, this device can be applied to motorized bicycles, railway vehicles, ships, and the like.
