What Indicators Measure the Performance of Headphone Speakers
1. Rated Power (W)
Headphone speakers exhibit various types of distortion, including harmonic distortion (often caused by non-uniform magnetic fields and distortions in the vibration system, typically occurring at low frequencies), intermodulation distortion (caused by the mutual modulation of two different frequency signals input simultaneously, degrading sound quality), and transient distortion (resulting from the vibration system's inertia failing to follow rapid signal changes). Harmonic distortion refers to the addition of harmonic components not present in the original signal during playback. Sources of harmonic distortion in speakers include nonlinear distortions from uneven magnetic fields, diaphragm characteristics, and voice coil displacement. Currently, high-quality speakers exhibit harmonic distortion of no more than 5%.
2. Headphone Speaker Sensitivity (dB/W)
The sensitivity of a headphone speaker typically refers to the sound pressure level measured at 1m on the axial front when a noise voltage with an input power of 1W is applied. Sensitivity indicates the speaker's ability to reproduce subtle details in the audio signal. Higher sensitivity ensures the speaker responds accurately to all nuances in the audio signal. Hi-Fi speakers should have a sensitivity greater than 86dB/W.
3. Headphone Speaker Directivity
The sound pressure frequency response of headphone speakers varies with radiation direction, a characteristic known as directivity. It relates to the speaker's diaphragm size: larger diaphragms exhibit sharper directivity, while smaller ones have wider dispersion. Directivity also depends on frequency; generally, frequencies below 250Hz show minimal directivity, whereas frequencies above 1.5kHz exhibit pronounced directivity.
Headphone speakers feature compact, lightweight design. Built-in amplifier, diversity wireless receiver, only 3.6kg for easy portability. 2. Simple installation. 3: Equipped with external input ports for BGM, etc. 4: Compatible with WX-4800 for integrated portability. 5: Usable outdoors (when connected to an external DC12V power source, enabling wireless broadcasting without broadcast equipment! Built-in diversity wireless receiver, weighs approx. 3.6kg, easy to carry and transport, suitable for mobile use across multiple rooms. Features a powerful 12cm conical full-range speaker and a 10W output amplifier that delivers clear sound despite its compact size.
