Products Overview


The core products sold by Piezo Source are the original piezoelectric speakers and receivers designed, patented, and manufactured by Motorola/CTS for over 30 years.In addition to offering many of the original Motorola/CTS products, Piezo Source has developed new designs and materials to support the needs of new and existing customers and their developing applications. Our products consist of 62% Horn Tweeters, 13% Horn Drivers, 8% Voice Range Speakers and 17% Alarms.

Piezo Source Distinguishes

The performance, design, and manufacturing quality of the Piezo Source products are backed by our Ph.D. level lead design and manufacturing teams. These teams are able to offer direct support to our customers from our dual locations in San Jose, CA and metropolitan Manila in the Philippines.
Piezo Source devices are parametrically tested during the manufacturing process, and each device undergoes final functional testing before shipment. Piezo Source logs and archives all the parametric and functional test data into our proprietary DataCruncher. Key collaborators can request serialized products where the full suite of test data is available through DataCruncher's cloud-based web portal.
The Piezo ceramic at the heart of the Piezo Source product line is of the highest medical grade quality, similar to what is found in hospital equipment. Piezo Source products offer the necessary robustness for applications where long term performance and stability are important.
Motorola/CTS spent over 30 years researching and developing the materials and designs for the piezoelectric devices. These R&D efforts included the plastics, horn geometry, ceramics, and centervane construction, and form the central base of the Piezo Source intellectual property.
Piezo Source acquired the entire manufacturing line from Motorola/CTS, including the molds for the speaker housings. Our products are manufactured and tested on the original manufacturing equipment, ensuring that many of our products are 100% equivalent to the original Motorola/CTS piezoelectric speakers and receivers.
Motorola and CTS developed detailed standard operating procedures regarding the manufacturing process for their piezoelectric devices. Piezo Source owns these and applies them to our manufacturing process for our product offerings.
