Audio transformer basics, Buy Audio transformer
In the vast field of audio technology, audio transformer, as an important electronic component, plays a key role in the processing and transmission of audio signals. Different types of audio transformers are widely used in various audio devices due to their unique design and performance. Today, MobikeChip will bring you an in-depth understanding of the types of audio transformers.
Power Audio Transformer
(A) working principle and structure
Power audio transformer is mainly used in the power supply part of audio equipment. Through the principle of electromagnetic induction, it converts the input AC voltage into different voltage levels suitable for audio equipment. Its structure usually consists of primary winding, secondary winding and iron core. The primary winding is connected to the input power supply, while the secondary winding outputs the required voltage. The role of the iron core is to enhance the magnetic field coupling and improve the efficiency of the transformer.
(B) Application Scenarios
In many audio devices, such as power amplifiers and mixers, a stable power supply is required to drive the circuitry. The power audio transformer is capable of converting the mains voltage into different voltages required by the internal circuits of the equipment, such as providing a low voltage for the preamplifier and a high voltage for the output stage of the power amplifier. It ensures that the audio equipment can operate stably under different voltage requirements, providing reliable power support for audio signal processing.
Input Audio Transformer
(A) Functional characteristics
Input audio transformer is mainly used for audio signal input interface part. Its main function is to realize the matching and isolation of audio signals. In the audio equipment, different signal source output impedance may be different, the input audio transformer can be adjusted through the winding turns ratio, the impedance of the signal source and the input impedance of the audio equipment to match, so as to ensure that the audio signals can be efficiently transmitted, reduce signal distortion. At the same time, the input audio transformer can also play a role in isolation, to prevent electrical interference between the signal source and the audio equipment, to improve the purity of the audio signal.
(B) Common applications
In the field of professional audio, such as recording equipment, radio stations, etc., the input audio transformer is widely used. For example, in the microphone input circuit, the input audio transformer can convert the low output impedance of the microphone to the high input impedance required by the audio equipment, and at the same time isolate the noise between the microphone and the audio equipment, so that the recorded sound is more clear and accurate.
Output Audio Transformer
(A) Performance Advantages
Output audio transformer is used at the output of audio equipment, responsible for transmitting audio signals from audio equipment to loads, such as speakers. It has good frequency response characteristics, can maintain the amplitude and phase stability of the audio signal in a wide frequency range, to ensure that the audio signal is not distorted in the transmission process. In addition, the output audio transformer can also provide a certain power matching function, the output power of the audio equipment effectively transferred to the speakers, so that the speakers can emit loud and clear sound.
(B) Applicable equipment
In all types of audio power amplifiers, the output audio transformer is one of the key components. Whether it is the amplifier in the home audio system, or the high-power amplifier in the professional performance venue, the output audio transformer can accurately transmit the amplified audio signals to the speakers, promote the work of the speakers, and bring the listener a high-quality listening experience.
The isolation of audio transformers
(A) isolation principle
Isolation of the main role of the audio transformer is in the audio signal transmission process, to achieve electrical isolation, to prevent interference between different circuits and noise transmission. It is completely isolated electrically by the primary winding and secondary winding, only through the magnetic field coupling to transmit audio signals. In this way, even if there are potential differences or sources of interference in the circuits connected to the primary and secondary windings, they will not affect each other, thus ensuring the purity and stability of the audio signal.
(B) Application areas
Isolated audio transformers are widely used in some occasions where the quality of audio signals is required to be extremely high, such as medical audio equipment, high-end recording studios and so on. In medical equipments, it can prevent electrical interference between equipments and ensure accurate acquisition and transmission of medical audio signals; in recording studios, isolation audio transformers can isolate noise between different audio equipments and provide guarantee for high quality audio recording.
