Low power consumption
Power consumption comparison (conducted by TAIYO YUDEN)
| Characteristics | Eccentricity motor | LRA (rectangular-type) | Piezo |
|---|---|---|---|
| Actuator-type | Inertia | Inertia (horizontal) | Piezo |
| Force feedback | Possible | Possible | Possible |
| Tactile feedback | Not possible | Possible | Superior |
| Frequency | 1 to 300 Hz | 175 to 250 Hz | 1 to 500 Hz (all bands) |
| Waveform | Sine wave | Sine wave | Sine wave |
| Response time | 40 to 80 ms | 20 to 30 ms | Less than 1 ms |
| Phonation | Not possible | Not possible | Possible |
| Size | 12 mm x 3.5 mm, t2.7 mm | 20 mm x 7 mm, t3 mm | 53 mm x 8 mm, t0.3 mm |
| Low power consumption | Average | Good | Excellent |
| Advantages | Inexpensive Vibrations transmitted in all device directions | Small circuit component area Widespread adoption | Fast response speed High frequency band support |
| Disadvantages | Extremely slow response speed Single frequency High power consumption | Slow response speed Single frequency Thick | Must be affixed to the panel High cost |
