Abstract:
The strike sound producing assembly is provided for a watch striking mechanism. The assembly includes at least one gong, which is directly integral by means of a gong-carrier with an assembly element inside a watch case to form a single piece. A first end of the gong is fixed to the gong-carrier, whereas a second end of the gong is free to move.
Abstract:
The musical or striking watch is provided with an acoustic radiation arrangement. The watch includes a watch case, formed at least of a case middle and a back cover removably fixed to the case middle, and at least one crystal for closing said case. The acoustic radiation arrangement includes a connecting support part fixed in the case back between a back bezel and a back crystal. The back bezel includes several lateral openings. A cavity is defined between the connecting support part and the openings in the back bezel.
Abstract:
A musical door chime which includes a repertoire of musical tunes one of which is played when a door pushbutton, preferably the front door pushbutton, is actuated. The musical tune which is played may be selected by means of a keyboard connected to a microprocessor. Digitally encoded representations of the notes of each musical tune are stored in a memory. Each digitally encoded musical note is read from memory by the microprocessor and converted by the microprocessor into a squarewave having the frequency and the duration of the note. The microprocessor is connected to a note strike and decay circuit which is preferably connected in series with an active audio filter circuit for translating the squarewave into a sinusoidal output for energizing a loudspeaker so that relatively high quality audible tones are heard when the musical tune is played. Preferably, a two-note musical tune is played when a rear door pushbutton is actuated, and a fixed single musical note is played when a side door pushbutton is actuated. The musical door chime is preferably also combined with a visual display driven by the microprocessor for indicating the time of day. The time is preferably annunciated every quarter hour by means of musical notes. A multi-frequency tone is played for the hour strike. The keyboard serves various other control functions in addition to selecting the musical tune to be played.
