Description of the Invention: [Technical Field] [0001] The present invention relates to a sound output device, and more particularly to a sound output device having a compensation characteristic. [Prior Art] [0002] The role of the speaker is to convert an audio electric power signal within a predetermined range into a sound having a sufficient sound pressure level. As living standards improve, users demand that speakers restore audio audio signals to lifelike sounds. [0003] Human voice and various music systems are a kind of random signal 'the waveform is very complicated.' The frequency range of the sound that can be heard by the human ear is generally 20HZ-20KHZ, and the frequency range of the language is about 150Hz-4KHz; and the frequency of various music The range is from 40Hz to 18KHzA; the energy of human voice is mainly concentrated in the frequency range of 200Hz-35KHz. Therefore, the speaker should be able to properly reproduce these random signals to ensure the sound quality of the playback. The speaker must have a wide frequency efficiency characteristic, sufficient sound pressure level and a large signal dynamic range, and cannot generate signal delay. Among them, the characteristic parameters that have a relatively high impact on the effect of the speaker are: frequency efficiency and frequency phase delay. Frequency efficiency is the ratio of the output power to the input power obtained by inputting a signal of a certain power at different frequencies. The frequency phase delay is different. The signal is phased into a phase of the signal and the resulting signal phase is advanced or delayed relative to the phase of the input signal. In a typical speaker system, the curve indicating its frequency efficiency and frequency phase delay is a curve wave that varies greatly. [0004] To solve the above problems, some prior art correction systems are used to correct the characteristic parameters of the speaker. A reference load amplifier correction system as disclosed in U.S. Patent No. 4,482,866, which is incorporated herein by reference to the entire entire entire entire entire entire entire entire entire entire entire entire entire contents Drive loads such as the opposite characteristics of a speaker or multi-speaker system, such as reactance, inertia, and response. It applies a program voltage to a reference load that drives the load characteristics. The program and correction voltage signals are simultaneously applied to a power amplifier to correct the opposite characteristics of the load. However, this type of correction mainly uses resistors and capacitors to construct a correction system. The system has many components and its structure is complex, and it cannot be compensated according to the individual characteristics of the drive load. [0006] In order to eliminate the drawbacks of the conventional speaker correction system, a sound output device having compensation characteristics of the present invention has been created. SUMMARY OF THE INVENTION [0007] It is an object of the present invention to provide a sound output device, and more particularly to a sound output device having compensation characteristics. Another object of the present invention is to provide a compensation system including a sound output device having compensation characteristics. .
