The present invention provides a timepiece and a portable device. In the timepiece that produces sound by vibrating when struck, the elastic force of each spring can be easily set, and superior sound can be produced. The timepiece (1) having a movement (1A) having a hammer (40) and a hammer drive device (40) that drives the hammer, a sound source (20) that produces sound by vibrating when struck by the hammer, and a striking force transmission member (50) that can move bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer (40) to the sound source (20).

A timepiece having a movement having a hammer and a hammer drive device that drives the hammer, a case that houses the movement, a sound source that produces sound by vibrating when struck by the hammer, and a striking force transmission member that can move bidirectionally between the hammer and the sound source, and transmits the striking force of the hammer to the sound source.

A tool for reporting a particular time using vibration is disclosed. The tool assigns a distinct vibration to separate hour regions and minute regions. The tool uses a short series of vibration pulses, one of which is the distinct vibration assigned to the hour region associated with the hour of the particular time, to indicate the hour. The tool produces the distinct vibration assigned to the minute region associated with the minute of the particular time, to indicate the minute to the nearest quarter hour. The total sequence of pulses consists of no more than five separate vibrations.

The strike mechanism (1) of a watch includes a gong (21), which is secured by one end thereof to a gong-carrier (22) integral with a plate, a hammer (2) rotatably mounted on the plate for striking the gong (21) at predetermined times, a damping counterspring (5) for keeping the hammer at a distance from the gong (21) in an idle mode, and a spring (3) for driving the hammer. The drive spring includes one end (3b) secured to the plate and one end (3a) that is free to move. The spring is capable of being wound so as to drive the hammer (2) against the gong (21) in a strike mode to generate an acoustic sound. The strike mechanism further includes a stop member (10) on the path of the hammer drive spring in the direction of the gong for increasing the strike speed following contact of an intermediate part of the drive spring (3) in action against the stop member.

A timepiece has a timekeeping mechanism for keeping and displaying the time, a hammer, a bowl-shaped sound source that sounds when struck by the hammer, a sound source mounting member for fastening the bowl-shaped sound source to the timekeeping mechanism, and a striking control means for causing the hammer to operate. The bowl-shaped sound source has a bottom part and a side wall part. The hammer, the striking control means, and at least a part of the timekeeping mechanism are disposed in an internal space between the bottom part and the side wall part of the bowl-shaped sound source. The sound source mounting member is attached to the center of the bottom part of the bowl-shaped sound source, and fastens the bowl-shaped sound source to the timekeeping mechanism so that the bowl-shaped sound source can move a prescribed distance within a range not contacting the case of the timepiece or the timekeeping mechanism.

The strike mechanism (1) of a watch includes a gong (21), which is secured by one end thereof to a gong-carrier (22) integral with a plate, a hammer (2) rotatably mounted on the plate for striking the gong (21) at predetermined times, a damping counterspring (5) for keeping the hammer at a distance from the gong (21) in an idle mode, and a spring (3) for driving the hammer. The drive spring includes one end (3b) secured to the plate and one end (3a) that is free to move. The spring is capable of being wound so that the free end (3a) of the spring drives the hammer (2) against the gong (21) in a strike mode to generate an acoustic sound. The strike mechanism further includes a stop member (10) on the path of the hammer drive spring in the direction of the gong for increasing the strike speed following contact of an intermediate part of the drive spring (3) in action against the stop member.

A watch with a clockwork comprising a ringer whose actuation is controlled from outside the watch by means of a control unit, a dial plate comprising an opening, a shutter (10) movable between a first position covering the opening and a second position leaving the opening free. The control unit (12) is arranged in such a way that it enables the shutter to be moved from the first position to the second position when the ringer is actuated.
