Dual sound toy train set
First Claim
1. A dual sound toy comprising:
- a track;
a toy vehicle movable on said track having battery-powered propulsion means;
control means responsive to a first inaudible sound frequency within said toy for causing said propulsion means to alternate between operative or inoperative states each time said first sound energy is received; and
sound producing means for simultaneously producing sound energy at said first sound frequency and sound energy at a second audible sound frequency.

Abstract
A dual sound toy train set includes a toy track formed in a continuous loop and having guiding rails on either side thereof. An electrically powered toy train engine is coupled to the track and includes an internal battery power source, an electric drive motor and a motor control unit. An ultrasonic microphone is supported upon the toy train engine and operatively coupled to the motor control unit. A sound unit includes a housing supporting a pair of air bellows having one way inlet valves attached thereto. A movable pump handle is operative to collapse the air bellows and produce pressurized air streams which are coupled by hollow tubes to an ultrasound whistle and an audible sound whistle. The audible sound whistle produces exciting play sounds similar to those produced by conventional locomotives. The ultrasonic energy produced by the ultrasound whistle is received by the microphone on the toy train engine and is used to alternately energize and deenergize the electric drive of the toy train to start and stop the toy train.

9. A dual sound toy train set comprising:
-
a toy train having a battery-powered propulsion means and an ultrasonic sound energy responsive control system for alternatively propelling and stopping said toy train each time ultrasonic sound energy is received; a first air bellows and ultrasonic whistle coupled thereto; a second air bellows and an audible train whistle coupled thereto; a mechanical coupling arm link secured to said first and second air bellows; and a handle pivotally movable against said arm link to simultaneously compress said first and second air bellows and cause said ultrasonic whistle and said audible train whistle to operate. - View Dependent Claims (10)
