摘要： A waterproof construction around a miniature buzzer incorporated in an electronic alarm watch depends on a gasket alone. The construction is such that the gasket can secure a resonant plate without any storage of distortion in the resonant plate. This feature makes it possible to provide the electronic alarm watch having a stable performance for acoustic emission.

摘要： A miniature electronic buzzer for an electronic watch has two vibrating plates with a sealed space between them forming an air spring. One of the vibrating plates carries an amarature which is acted upon by an electromagnetic to vibrate said plate. Vibration is imparted to the other vibrating plate by the air spring. The two vibrating plates and coupling air spring constitute a vibrating system having two resonant frequencies in the audible range. The electromagnet is energized by current having a frequency in the neighborhood of these resonant frequencies. There may be a third vibrating plate coupled with the second vibrating plate by a second air spring. In this event the vibrating system has three resonant frequencies in the audible range.

摘要： A small acoustic device is provided with a housing, a first electrically actuated vibrating plate and a second vibrating plate. A support member cooperates with the housing for mounting the periphery of the second vibrating plate to the housing to define therewith an airtight chamber. The support member also supports the periphery of the first vibrating plate in the airtight chamber with a gap between the two vibrating plates and air chambers on either side of the second vibrating plate. In this way, the barometric pressure in the two air chambers on either side of the second vibrating plate are equivalent and the device is both waterproof and independent of ambient temperature changes.

摘要： An alarm watch has an electro-acoustic transducer with a sound releasing cavity containing a vibrating plate for releasing an audible alarm sound. The surface of the vibrating plate exposed to the open air is treated with a water-repellant material having the property to shed or repel water so that when water enters into the sound releasing cavity and wets the vibrating plate, the vibrating plate readily throws off the water thereby obtaining rapid recovery of the alarm sounding function.

摘要： An electroacoustic transducer particularly for small small-sized portable equipment such as a wristwatch comprises a first vibrating plate which is vibrated by means of an electromagnet and a second vibrating plate which is coupled with the first vibrating plate by an airtight space which acts as an air spring. The first and second vibrating plates have different natural resonant frequencies so that the vibration system comprising the two vibrating plates and the air spring coupling them with one another forms a vibration system having two resonant frequencies. A resonant air chamber superposed on the second vibrating plate has a sound radiating port and has a resonant frequency between the two resonant frequencies of the vibration system comprising the first and second vibrating plates and coupling air spring. The electroacoustic transducer thus responds to a considerable range of frequencies.

摘要： An electro-acoustic transducer of electromagnetic type is composed of an exciting part having a magnetic core wound with an exciting coil, a vibrating plate provided opposite to the magnetic core at an interval and a ferromagnetic thin plate mounted to the vibrating plate. The thin plate is provided on the surface of the vibrating plate on the side of the magnetic core, so that the thin plate is not exposed to the open air. Furthermore, the thin plate is connected to the vibrating plate at plural points more than three or at a part with some area. Such connection restrains undesirable vibration of the thin plate.

摘要： A traveller having two ultrasonic motors, each of which movable member drives the driving wheel respectively. The ultrasonic motor comprises a vibrating member, a moving member and a pressure regulating member. The driving circuit sends signals to turn the ultrasonic motor, which turn the moving memeber to turn the driving wheel. With the driving wheel turning, the traveller travels freely in any direction. Each of two ultrasonic motors receives respective signals to travel freely in any direction as a effect.

摘要： An alarm wristwatch comprises a watchcase having a back with an inclined peripheral portion and a watchband attached to the watchcase at opposite sides. A transducer for generating an alarm signal faces a cavity provided in a rear portion of the watch case. A plurality of sound holes provided in the inclined peripheral portion of the watchcase back open into this cavity. The second holes are located within an angle of 45.degree. on either side of the longitudinal center line of the watchband so that they are not blocked or muffled by the arm of the wearer. The cavity and sound holes are so proportioned as to constitute a Helmholz resonator by which the sound produced by the transducer is intensified and efficiently transmitted to the exterior of the watchcase.
