Ultrasonic transducers with q spoiling

An electrical transducer system comprising:

• a) an electrical transducer comprising a substrate, a diaphragm, and a piezoelectric element;
• b) a first electrical circuitry coupled to the to the electrical transducer, the first electrical circuitry configured for driving the electrical transducer or detecting motion of the diaphragm;
• c) a plurality of electrical ports coupled to the electrical transducer;
• and
• d) a second electrical circuitry connected to two or more of the plurality of electrical ports, the electrical circuitry comprising one or more of:
• a resistor, a capacitor, a switch, and an amplifier;
• wherein the second electrical circuitry is independent from the first electrical circuitry, and wherein the second electrical circuitry is configured to dampen the motion of the diaphragm.

A method for damping motion of an electrical transducer, the method comprising:

• a) coupling a plurality of electrical ports to the electrical transducer;
• b) connecting a first electrical circuitry to two or more of the plurality of electrical ports, the electrical circuitry comprising one or more of:
• a resistor, a capacitor, a switch, and an amplifier, wherein the first electrical circuitry is independent from a second electrical circuitry, the second electrical circuitry configured for driving the electrical transducer or detecting motion of the diaphragm;
• and
• c) damping the motion of the electrical transducer using the first electrical circuitry.
