A coin-sized linear resonant actuator (LRA) generates vibration/haptic feedback in the Z-plane perpendicular to the motor surface. In wearable devices, motors are often mounted so that the surface of the motor is parallel to the user's skin, which makes these devices ideal because the vibrational energy will be directed at the user's skin rather than parallel to the user's skin. Other types of coin vibration motors (BLDC ERM, brush ERM) generate vibration forces parallel to the coin's face and the user's skin.

For haptic feedback applications, fast rise and fall times are critical for the best user experience. With this LRA series, it is possible to achieve 10 times faster rise times and 2 times faster fall times than standard coin-type ERMs. The high performance G1040003D LRA coin vibration motor provides very fast rise/fall times of 10 ms/50 ms respectively at 50% power and produces a considerable 2.0 G RMS vibration force. Compared with brush ERM coin vibration motors, the simple internal structure provides high reliability and long service life. They are an excellent choice for devices with limited battery capacity. For example, Golden Dragon's G0832012 draws 19 mA at 0.6 V while producing a vibrating G-force of 0.55 G RMS. . Requires an LRA driver IC such as the TI DRV2605. Available with double viscose, rubber foam pads and custom lead lengths.
