Signal sound discriminator for car
专利汇可以提供Signal sound discriminator for car专利检索，专利查询，专利分析的服务。并且PURPOSE:To enable discrimination of external alarm sound even for person of hard hearing by converting a signal discriminated from external sound into specific audio frequency signal then further converting into an acoustic signal. CONSTITUTION:Upon reception of winker sound of one's own car through a microphone 2, the voltage signal is removed of low band component through an alarm sound detection circuit 2 and a winker sound detection circuit 3 and the signal containing high frequency component will pass through flipflops 4, 5 to produce a rectangular wave which is fed through OR gate 7 to AND gate 8. When any one of them will go to H level, AND gate 8 will produce a signal through an audio frequency signal generator 9 which is sound converted through a voice output unit 10 with predetermined time interval set through a timer 6. Consequently, the driver can discriminate the winker sound of his own car or the external alarm sound easily.，下面是Signal sound discriminator for car专利的具体信息内容。
