Power transformer is working on a fixed frequency, such as 50HZ, 60HZ, 400HZ like. The audio transformer is in a wider frequency band, such as the audio range of 20HZ to 20000HZ. L0 transformer leakage inductance and stray capacitance C0. In power transformers is negligible, and in audio transformer, especially in the high end has become the main factor in determining the electrical indicator. So when the coil structural design, need to take certain measures leakage inductance and stray capacitance. Audio Transformer is an audio amplifier is an integral part, so during audio transformer design, it is necessary to determine the main parameters of the transformer, but also study the location and role of the amplifier can be divided into input transformer, inter-stage transformer, output transformers and lines between transformers. Operating frequency 20Hz ~ 20KHz, the transformer leakage inductance and stray capacitance Co Ls in power transformers is negligible. But especially for the high end audio transformers are a major factor in its electrical specifications, so the structural design considerations Index. Input transformer: transformer microphone and audio equipment from the impedance matching between the main role, its power is extremely small, high-conductivity magnet is usually made of nickel alloy small transformers in order to improve its sensitivity. Input from the audio line to the speaker or audio control equipment, also used as an audio transformer, from the impedance matching and isolation. It needs to have good electrical shielding and magnetic shielding, these transformers, also known as the input transformer. Interstage transformer: an amplifier stage between intermediate and transformers, such as coupling transformers, matching transformer and inverter transformers. Its role is to convert the audio signal voltage amplifier reaches match around. Output transformers: connected between the power amplifier stage amplifiers and speaker impedance conversion, and can output audio transformers. Interstage Transformers: cable broadcast equipment or power amplifiers, usually with more speakers, speakers and amplifiers distance, in order to reduce line power loss. Matching transformer: broadcast television system, the impedance of the two different transmission cables, impedance conversion by the wide band matching transformer, so that different transmission cable impedance matching. AM Transformers: broadcast transmission, the audio output of the transformer secondary winding in series with the high-frequency amplitude oscillation circuit in order to modulate the amplitude of high frequency oscillations, so that the audio signal to the high-frequency carrier wave, such audio output transformer called AM transformer.
