A watch includes a striking mechanism, including an attached gong (4) and a hammer (15), as well as a battery (6) and an integrated circuit (7) powered by the battery and configured to produce current pulses, and an electrodynamic actuator (17) which is connected to the integrated circuit and configured to receive said pulses, the actuator being integral with the hammer or connected to the hammer to generate in response to the pulses a movement of the hammer from a rest position thereof, the movement being able to actuate an impact of the hammer on the gong. The mechanism also includes a spring (27) connected to the hammer so as to return the hammer to its rest position after the impact. Depending on particular embodiments, the hammer undergoes one or more pre-oscillations before reaching the impact. The hammer and the gong may be provided with attracting magnets.

A haptic device for an electronic device includes an actuation member formed from a shape-memory alloy (SMA) material that changes shape (e.g., expands or contracts) in response to an applied electrical current. In some cases, the haptic devices described herein also include a restoration mechanism that restores the actuation member to its original shape or to a similar shape. The change in the shape of the actuation member and the restoration of the shape of the actuation member may produce a haptic output at the electronic device.

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.

Embodiments for implementing intelligent alarm sound control by a processor. A targeted entity may be isolated for a generated sound to be delivered, while noise cancellation is simultaneously provided to prevent an alternative entity from being disturbed by the isolated sound.

An acoustic device includes a waterproof vibrating membrane and a magnetic component disposed below the waterproof vibrating membrane. The waterproof vibrating membrane includes a convex portion which protrudes toward a position of the magnetic component, or a concave portion which is recessed opposing to a position of the magnetic component. The magnetic component includes a concave pressure buffering portion corresponding to a shape of the convex portion of the waterproof vibrating membrane wherein the concave pressure buffering portion is recessed toward a side opposing to a side on which the waterproof vibrating membrane is located, or a convex pressure buffering portion corresponding to a shape of the concave portion of the waterproof vibrating membrane wherein the convex pressure buffering portion protrudes toward a side on which the waterproof vibrating membrane is located.
