Electronic timepiece with electroacoustic transducer

An electronic timepiece having an alarm means and including a time base source supplying signals to a display control circuit for controlling a display, comprising:

• an electroacoustic transducer capable of emitting acoustic signals of audible frequencies in response to electrical audio frequency output signals and of producing electrical audio frequency input signals in response to received acoustic signals of audible frequencies;
• and
• a watch and transducer control logic network coupled to said time base pulse source, said display control circuit, and said electroacoustic transducer, said control logic network including first means coupled to said time base pulse source for generating said electrical audio frequency output signals;
• said control logic network including second means responsive to said electrical audio frequency input signals produced by said transducer for effecting a change in a predetermined operative condition of the timepiece;
• said control logic network further including selector means normally operatively connecting said electroacoustic transducer to said second means whereby said transducer normally functions as a receiver of said acoustic signals of audible frequencies, said selector means further being responsive to activation of said alarm means for alternatively operatively connecting said transducer, alternately to said first means thereby causing said transducer to emit an acoustic alarm signal in response to said electrical audio frequency output signals, and to said second means thereby causing said transducer to receive said acoustic signals, thus permitting at least one operative condition of the timepiece to be controlled by an acoustic signal of audio frequency.
