摘要:
A sequenced audio help label having a plurality of recorded audio messages that are played back in a predetermined sequence, one at a time, in response to a user activating a button or trigger to signal play of the next message. The label may be affixed to e.g. consumer electronic devices as a quick-start help reference system for users. In some embodiments, the messages are pre-recorded, but, in others, the user may record the messages.

An exciting device capable of producing sound by sound-producing vibration body of a main body of an apparatus is provided. An exciting member 32A thin and long in the direction X is provided on a vibration substrate 31 thin and long in the direction X. Both ends of the exciting member 32A are fixed to the vibration substrate 31. Further, a piezoelectric element 33 that functions as vibration generating means is provided in the middle in the direction X of the exciting member 32A. The vibration substrate 31 is directly or indirectly fixed to the sound-producing vibration body. Vibration of the exciting member 32A is transmitted to the sound-producing vibration body through the vibration substrate 31 so that the sound-producing vibration body produces sound.

A hazard warning device for night-migrating birds is provided which warns the birds of the presence of a fixed structure or obstacle, e.g., a building or communications tower, against which the birds could collide during night-migration. The device includes a speaker affixed to the structure and a recorder connected to the speaker for, when activated, supplying to the speaker, for continuous broadcast thereby, an infrasonic signal which naturally causes the birds to avoid the structure. In one embodiment, the signal has a frequency close to that of a natural topographic feature and causes the birds to avoid the structure based on the workings of the innate navigational system of the birds. In another embodiment, the recorder supplies a signal which reproduces or mimics the sound of thunder and/or the sound of a lightning strike.

A novel modular audible signaling device is provided capable of expanded functionality, such as the provision of visual signaling as well. A piezoelectric transducer audible alarm signaling device is provided with an assembly having a housing defining an interior holding a piezoelectric transducer, the housing having a first exterior portion for attachment to a surface and a second exterior portion extending beyond the surface, wherein the first exterior portion and the second exterior portion comprise at least one pair of communicating apertures whereby an electrical conductor may extend through the at least one pair of apertures to the surface. In another aspect, a piezoelectric transducer assembly is provided having a housing defining an interior and a surface, the housing holding a piezoelectric transducer, wherein the housing further comprises an illumination element associated the surface thereof, the illumination element having one or more conductors which extend through the interior of the housing, whereby the illumination element may be electrically inserted into the same electrical circuit as the piezoelectric transducer.
摘要:
The present invention provides an alerting tone that daily life noises cannot mask, and that is therefore optimum to both young and elderly people. Through specifying various household activities performed in a home, measuring and analyzing frequency of the relevant operating noises (daily life noises) and quantitatively defining the actual status of background noises in a home where electric appliances are being used, alerting devices output an alerting tone having a predominant frequency substantially in a range lower than 3 kHz but not lower than 1.5 kHz, as an alerting tone designed in consideration of the daily life noises, and having the optimum frequency and sounding pattern for various apparatus.
摘要:
A pest repeller including at least a first ultrasound transmitter mounted on a base and a second transmitter rotatably mounted above the first transmitter. Both transmitters can be rotatably mounted on a common post carried by the base. The arrangements permit a greater ultrasound coverage of an area because of the relative rotation of the superimposed speakers.

A shrew-expelling device with an illumination function, the device is comprised of an electric circuitry, a main stem and a housing; wherein, the electric circuitry includes a power supplying circuit, a sound emitting circuit and a light emitting circuit, the power supplying circuit generates electricity in taking advantage of a solar-energy powered electricity generating element. The device with a buzzer and a light emitting element therein makes sound which is abominated by rodents and illuminates respectively; and thereby, the device has an effect of expelling rats and illuminating; wherein, by providing various modeling formed from a housing and a main stem, the device can completely immersed into the scenery of the environment to even beautify the latter.
摘要:
An audible alert device includes a pulse width modulated signal generator. The audible alert device and method for manufacturing the audible alert device also provides resonant frequency and decibel peaking capabilities. Resonant frequency and decibel peaking routines may conducted at the time of manufacture, upon startup of the alarm or during operation of the alarm. The audible alert device may be programmed during a manufacturing step to exhibit a selected operation mode so that one circuit may be manufactured and programmed to operate in any of a number of operation modes or device configurations. A programming station allows an audible alert device to be programmed during a manufacturing step to exhibit a selected operation mode. Programming may occur by connection of the audible alert device to the programming device by one or more audible alert device power conductors.
