METHOD FOR PRODUCING SOUNDS FOR TURN SIGNAL SOUNDS FOR AN AUTOMOBILE AND SOUNDER FOR TURN SIGNAL SOUNDS FOR AN AUTOMOBILE

WIPO Patent Application WO/2011/027688

A1

Disclosed are a method for producing sounds for turn signal sounds for an automobile and a sounder for turn signal sounds for an automobile, such that not only is cost minimized but a turn signal sound close to the operational sound of a mechanical relay can be output from a speaker. A turn signal sound pulse signal with a continuously changing frequency and duty cycle is output from a PPG port (21) of a CPU (2). An integrator circuit (31) integrates the turn signal sound pulse signal, converting that signal to a turn signal sound analog signal. A speaker (5) outputs the turn signal sound analog signal that had been converted by the integrator circuit (31). Also, alarm sound pulse signals of a constant frequency and constant duty cycle are output from S/G ports (22 to 23) of a CPU (2). Integrator circuits (32 to 34) integrate the alarm sound pulse signals, converting these signals to alarm sound analog signals. When an adder circuit (4) adds the turn signal sound analog signal to the alarm sound pulse signals and outputs the result to the speaker, the speaker outputs a turn signal sound and alarm sound at the same time.
