Transducers USA Introduces New Low Frequency Audio Indicators

ELK GROVE VILLAGE, Ill. (November 1, 2017)—Transducers USA, a supplier of audible signal devices, has announced the introduction of its new low frequency piezo audio indicators. These solid-state devices are ideal replacements for electro-mechanical audio devices that include moving parts, which eventually wear out.  This innovation represents a new approach to engineering audible signal devices as compared to the use of older electro-mechanical technology. Transducers USA is not aware of any other audible signal device manufacturer offering this new technology.

This new FLIP Series (Frequency-Low, Indicator-Piezo) contains a solid-state piezo ceramic bender, instead of the electro-mechanical device, which incorporates a coil that creates the magnetic field to drive a hammer and hit a membrane that actuates the buzzer. The FLIP ceramic piezo actuates its buzzer when voltage is applied to the piezo device itself. Without moving parts, the FLIP audio device will provide a much longer life and lower failure rate than its electro-mechanical counterparts.

The new FLIP Series is well suited for audible emergency alarms, such as those used in hospitals, nursing homes, medical centers, etc. They are ideal for smoke, CO2 and other detectors. The low-frequency FLIP buzzer, in combination with high-frequency beepers, provide a spectrum of alternative frequencies to accommodate both the normal and the hard-of-hearing, as is often the case in nursing homes.

The innovative FLIP Series has been designed in response to the need for alerts and alarms to be more detectable to the human ear, especially the hearing impaired.  The Hearing Loss Association of America reports “About 20 percent of Americans report some degree of hearing loss and at age 65, one out of three people has a hearing loss.” Legislation is currently pending to address this audio concern. The FLIP audio indicator is an ideal solution to this audibility issue, which is associated with traditional alarms, alerts and other audible signal devices. In addition, the longer operating life and lower failure rate of the FLIP Series make this solid-state device an exceptional alternative to electro-mechanical audible signal devices.

The FLIP low frequency notifiers will activate a buzzer that sounds almost identical to the electro-mechanical counterpart.  To demonstrate this, you can listen to and compare two audio files: one has a recording of an electro-mechanical buzzer, and the other has a recording of a FLIP piezo buzzer. Listen to the audio files at: https://clyp.it/user/bk3gwnq4 to experience the negligible difference among these two types of audible signal devices.

The frequency of the FLIP Series audio indicators is 400 Hz +/- 50 Hz, and can range from 350 Hz to 450 Hz. The SPL is 95 dBA @ 10 cm and the voltage rating is 12 VDC.

Transducers USA will provide modifications to its standard FLIP parts, as well as custom design FLIP indicators, with variations in parts and packaging.

The price point for the FLIP Series will be slightly higher than that for its electro-mechanical counterpart, but the FLIP indicators will provide greater reliability and longevity.
