Does such a component exist? - Electronic Circuits Projects Diagrams Free

Let's say I have a switch between a small motor and its powersource,
I need that switch to be turned on whenever it recieves and audio tone and I need it to turn off whenever the tone stops, how could I accomplish this?

basically:
I need the switch to be on when it recieves the tone and to turn off when the tone stops

thanks

Is this a DC motor?

Yes it is a DC motor

What are the voltage and current demands of the motor?

What frequency is the tone?

What is the voltage of the tone?

Read the data sheet for a NE567 ; should work well by driving a relay trough a transistor.
