Frequency response: Frequency response refers to the ability of a hanging speaker to respond to different frequencies, which determines the clarity and fidelity of the sound quality. A speaker with a wide frequency spectrum response can provide "high fidelity" sound quality, making music sound more real and natural.
Impedance: The impedance of a speaker refers to the degree of its resistance to electric current. The size of the impedance directly affects the volume and sound quality characteristics of the speaker output. Low-impedance speakers usually output louder and thicker sound, suitable for occasions where the bass effect is more prominent; while high-impedance speakers output clearer sound, suitable for occasions where the treble effect is more outstanding. In addition, impedance matching is also very important. If the impedance of the speaker does not match the output impedance of the audio device, it may cause the audio signal to be reflected back to the player, causing noise and sound quality loss.
Sensitivity: The sensitivity of a speaker refers to its sensitivity to audio signals. The higher the sensitivity, the stronger the speaker's response to the audio signal, and the better the sound quality performance is generally. Under the same input power, a high-sensitivity speaker can produce a greater sound pressure level, that is, a louder volume.
Non-harmonic distortion: Harmonic distortion refers to the additional harmonic components generated by the speaker when playing audio, which will have an adverse effect on the sound quality. The smaller the non-harmonic distortion, the purer the sound quality of the speaker.
Directivity: The directivity of the speaker determines the propagation direction and range of the sound, and has a certain impact on the sound field positioning. Speakers with strong directivity can better control the diffusion range of the sound, reduce the impact of reflections such as walls and ceilings on the sound, thereby improving the clarity and sound quality of the sound.
Transient response: Transient response refers to the speaker's ability to respond to sudden signals, which determines the dynamic performance of the music. Speakers with good transient response can respond quickly and accurately to changes in audio signals, making the music sound more vivid and powerful.
Diaphragm material: The diaphragm material plays a vital role in the sound quality of the speaker. Different diaphragm materials determine the sound quality orientation of the speaker. The ideal diaphragm material should have a high elastic modulus, low density and appropriate internal damping, so that the speaker can propagate quickly, rise quickly, and have appropriate internal damping to damp out unnecessary clutter, making the sound clean and soft.
