Distortion of this crystal occurs when a stress is applied to the element either thermally, mechanically or electrically. For piezo sounder applications a metal plate is typically attached to the ceramic element and it is this plate which vibrates due to the expansion and contraction of the piezo ceramic the resonant frequency of the ceramic is too high to produce an audible tone directly itself).

DSW Siren is the loudest dual tone piezo siren alarm at 3.5 inch diameter. It can be installed indoors or outdoors.
Our Alarm siren is a great addition to any compatible security alarm system. The alarm siren is a 6-12 V DC combination speaker and siren driver. DSW alarm siren is dual tone – warble or steady.
