Apparatus for outboard engine for switching to voice alarm output
First Claim
1. An apparatus for use in an outboard engine for switching a voice alarm output, comprising:
- a plurality of sensors for detecting respective abnormal states, including abnormality of a cooling water;
a voice output circuit for receiving output signals from said plurality of sensors and for outputting a voice signal identifying the abnormal state;
acoustic reproducing means for producing an audio output signal;
a speaker; and
voice discriminating switching means for detecting a level of an audio output signal from said voice output circuit and for temporarily switching the speaker from being connected to the acoustic reproducing means to being connected to the voice output circuit in response to detection of said level.

Abstract
An apparatus for use in an outboard engine provides a voice alarm output when an abnormality of cooling water or the like is detected during operation of a radio or the like, the abnormal state being announced with a synthesized voice. The apparatus has a plurality of sensors for detecting the abnormality of the cooling water and the like, and a voice output circuit to receive detection signals from the sensors and to output a synthesized voice signal identifying the abnormal state. An acoustic reproducing apparatus such as a radio is provided, and a common speaker is used to output the radio output or the voice output signal of the voice output circuit. A voice discriminating switching circuit is provided between the voice output circuit and the acoustic reproducing apparatus. The voice discriminating circuit detects the level of an output signal of the voice output circuit and temporarily switches the speaker from the acoustic reproducing apparatus to the voice output circuit in response to the level.
