This page explains how Acoustic Driver is classified within Computer, Electronic and Optical Product Manufacturing. Technical values and manufacturer relationships are research references; confirm the current specification and supplier evidence for each order.
The electroacoustic transducer that converts electrical audio signals into sound waves in headphones.
Technical details and manufacturing context for Acoustic Driver
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Impedance | 16–32 Ω | Typical for consumer headphones; lower for in-ear, higher for over-ear. |
| Sensitivity | 100–120 dB SPL/mW | Higher sensitivity requires less power for same loudness. |
| Frequency Response | 20–20000 Hz | Full audible range; deviations affect tonal balance. |
| Rated Power | 10–50 mW | Maximum continuous power before distortion or damage. |
| Total Harmonic Distortion | ≤1 % | At 1 kHz, 1 mW; lower is better for fidelity.IEC 60268-7 |
| Operating Temperature | -20–70 °C | Outside range may degrade magnetic or diaphragm performance. |
| Storage Temperature | -40–85 °C | Non-operating survival range. |
| Humidity Range | 10–90 % RH | Non-condensing; high humidity may affect diaphragm. |
| Weight | 1–10 g | Per driver; lighter reduces headphone weight. |
| Magnet Material | NdFeB | Neodymium for high flux density; ferrite cheaper but weaker. |
| Diaphragm Material | PET | Polyester film; other options include polyurethane or metal. |
| Voice Coil Diameter | 10–30 mm | Affects power handling and high-frequency response. |

CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
Typical impedance for consumer headphone drivers is 16–32 Ω. Lower values are common for in-ear models, while higher values are used in over-ear models. Always confirm the exact impedance for your specific driver model with the manufacturer.
Sensitivity, measured in dB SPL/mW, indicates how efficiently the driver converts electrical power into sound. Higher sensitivity means the headphones can produce the same loudness with less power, which is beneficial for portable devices. Typical values range from 100–120 dB SPL/mW.
THD measures the amount of distortion added to the audio signal. Lower THD indicates higher fidelity. For this driver, THD is ≤1% at 1 kHz and 1 mW, per IEC 60268-7. This is a reference value; verify the actual THD for your model.
The driver is designed to operate in temperatures from -20 to 70 °C and humidity from 10 to 90% RH (non-condensing). Storage temperature range is -40 to 85 °C. Exceeding these limits may degrade performance or cause damage.
