The main performance indicators of the loudspeaker include: sensitivity, frequency response, rated power, rated impedance, directivity, distortion and other parameters.
1. Rated power
(1) The power of loudspeaker can be divided into nominal power and maximum power. The nominal power is called rated power and undistorted power. It refers to the maximum allowable input power of the loudspeaker within the rated undistorted range. The power marked on the trademark and technical specification of the loudspeaker is the power value.
(2) The maximum power refers to the peak power that the loudspeaker can withstand at a certain moment. To ensure the reliability of the loudspeaker, the maximum power of the loudspeaker is required to be 2-3 times of the nominal power.
2. Rated impedance
The impedance of loudspeaker is generally related to frequency. Rated impedance refers to the impedance measured from the loudspeaker input when the audio frequency is 400Hz. It is generally 1.2~1.5 times the DC resistance of voice coil. The common impedances of general moving coil loudspeakers are 4 Ω, 8 Ω, 16 Ω, 32 Ω, etc.
3. Frequency response
(1) When an audio signal with the same voltage but different frequencies is applied to a loudspeaker, the sound pressure generated will change. In general, the sound pressure generated by medium audio is large, while the sound pressure generated by low audio and high audio is small. When the sound pressure drops to a certain value of medium audio, the high and low frequency range is called the frequency response characteristics of the loudspeaker.
(2) The ideal loudspeaker frequency characteristic should be 20~20KHz, so that all audio can be played back evenly, but this is impossible. Each speaker can only play some part of the audio well.
