The main technical parameters of the loudspeaker are rated power, nominal impedance, frequency response and so on.
( 1 ) Rated power. The power of the loudspeaker is divided into the nominal power and the maximum power. The nominal power is also called rated power and undistorted power. It refers to the maximum input power allowed by the loudspeaker in the range of distortion, which is the power value that is marked on the label of the loudspeaker and the technical specification. The maximum power of the loudspeaker is the peak power that the loudspeaker can bear in a certain instant. In order to ensure the reliability of the work of the loudspeaker, the maximum power of the loudspeaker is required to be 2 to 3 times of the nominal power. The power of common speakers is 0.1W, 0.25W, 1W, 2W3W, 5W, 10W, 60W, 120W and so on. ( 2 ) nominal impedance. The nominal impedance of the loudspeaker, also known as the rated impedance, is the loudspeaker ( AC ) impedance specified by the manufacturer. On this impedance, the speaker can get the maximum output power. Usually, the nominal impedance of a loudspeaker with a calibre less than 90 mm is measured with a test frequency of 1000 Hz, and the nominal impedance of the loudspeaker greater than 90 mm is 400 Hz measured by the frequency of the test. When selecting a loudspeaker, the nominal impedance is an important index, and its nominal impedance should generally be consistent with the output impedance of the audio amplifier. ( 3 ) Frequency response frequency response, also known as effective frequency range, refers to the effective frequency range of sound reproduction of loudspeakers. The frequency response range of the loudspeaker is obviously wider and the better, but subject to the restriction of structure and price, it is not generally possible to be very wide the frequency response of 130mm or 5in is mostly 120 ~ 10000Hz, and the frequency response of the same size rubber edge or foam edge loudspeaker can reach 55 Hz ~ 21 kHz.
4. The speaker detection method will use the multimeter RX 1 block, any one of the stylus and the speaker at the end of either end, with another pen intermittent touch Yang the other end of the acoustic device, at this time, the speaker should be issued " click " sound, the pointer also swing accordingly. If the speaker does not make a sound when touching, the pointer does not swing, indicating that the inner voice coil of the loudspeaker is broken or the lead is broken.

Well, that's fascinating, I'm sure, but you are a spammer, so you have been banned.
