Linear resonant actuator working principle
Many people doubt why the LRA's vibration force is stronger than ERM type coin vibration motor.That's because the linear vibration motor's auto-resonance vibration strength. Linear resonant actuators have a very narrow resonant frequency. The narrow resonance is a result of the resonance behavior of the spring and mass inside the LRA. An LRA will have a resonance at one frequency with a steep drop on either side.
The graph in Figure shows acceleration versus frequency using three different driver output voltages. As the voltage increases, likewise the acceleration, the resonance frequency shifts making it impossible to predetermine the resonance frequency of an LRA. Auto-resonance will ensure vibration performance across all actuators, no matter the resonance frequency. TI’s auto-resonance algorithm dynamically determines the resonance frequency as the actuator is vibrating.

Still can’t find ideal motors?
The electrical parameters of the motor can be adjusted. For example, the two main factors determining the vibration force: the size of the pager motor eccentric mass and the speed requirement. , voltage, current can be adjusted according to customer needs. Some encapsulated vibration motors adding terminals connectors, which are our customized products according to different customers. You can also contact us in the bottom contact form to ask for your needs.
If you want a custom lead wire connection of the water resistant vibration motors. Such as alternate lead wire length & strip lengths, with a connector (e.g. Molex, JST). You can contact us from the footer form, tell us your need. Any problems will be taken seriously and will be answered professionally, so pls do not hesitate to contact us by the footer form.
