A musical or striking mechanism (1) for a timepiece or musical box, includes an energy source (6) delivering a mechanical torque and device for transmitting mechanical torque from the energy source to a wheel set for generating music or a striking wheel set (4). The mechanism also includes a wheel set governor (2) configured to regulate, around a reference speed value, the pivoting speed of the wheel set about a pivot axis, and including a break for braking the wheel set configured to return the pivoting speed thereof to the reference speed. The wheel set governor includes a system having an electric generator (16) whereof a rotor is mechanically connected to the energy source delivering the mechanical torque, and an electronic circuit for regulating the rotation speed of the generator.

The control device includes a touch sensor circuit, a control circuit, a driving circuit and a switching circuit. The touch sensor circuit is configured to generate a touch signal and a function signal in response to a touch state of a touch component. The control circuit is activated by a first voltage. The control circuit selectivity generates a self-holding signal according to the function signal when it is activated. The driving circuit is configured to generate a drive signal according to the touch signal or the self-holding signal. The switch circuit is turned on by the drive signal so as to provide the first voltage to the control circuit by the turned-on switching circuit. When the control circuit generated the self-holding signal, the control circuit is configured to continuously transmit the self-holding signal to the driving circuit according to the function signal during a first enabling period.
