Welcome to Piezo Source, Inc.
The proprietary manufacturer of the Motorola bimorph piezo technology

The Piezo Source bimorph Motorola speakers are not the same as simple piezoelectric speakers. Our manufacturing process is roughly equivalent to having a speaker with two crystals rather than one. This gives our speakers a much longer lifespan, efficiency and long term performance and stability. To ensure quality Piezo Source is ISO Certified (ISO (TS) 16949).
Piezo Source, Inc. has been manufacturing and supplying the highest quality piezoelectric speakers since acquiring the exclusive rights, designs, and manufacturing line from Motorola/CTS in 2005. The speakers manufactured by Piezo Source maintain the high quality originally ensured by Motorola and later by CTS.
The quality of our bimorph ceramics means that our speakers are also used as a transceiver - speaker and microphone.
Piezo Source supports our customers through:
  • Manufacturing high quality piezoelectric speakers - Over 100 speakers available in our product portfolio.
  • Engineering and design - Our team of Ph.D. engineers collaborate with our clients on new designs, materials, and signal processing methods.
  • Sub-contract manufacturing - With our key collaborators, Piezo Source performs sub-contract manufacturing where we help with the mechanical and electrical assembly involved in mounting speakers into customers' boxes and arrays.
