There have been numerous indicators that demonstrate the growing trend towards waterproofing mobile equipment. For example, of the 50 new Japanese mobile phone models announced in late 2010, almost one in four were waterproof. This trend is aided by Murata’s speaker ability to overcome the above mentioned technical and cost challenges. Specific speaker characteristics include an average sound pressure level of 92.0±3.0dB (1400Hz±20%, 5Vrms sine wave, 10cm) and a capacitance of 0.9μF±30%.
“We developed this waterproof speaker based on feedback from our customers and market trends,” said Peter Tiller, senior group product manager, Murata Electronics North America. “Too often we hear of consumers losing a phone or camera due to accidental submersion in water. We hope our new speaker will allow more mobile consumer products to be waterproof and survive life’s little accidents.”
Sample pricing of Murata’s waterproof piezoelectric speaker is approximately $2.90 in small quantities and the lead-time is 11 weeks. Further information can be found on-line at http://www.murata-northamerica.com
