pin transformerIt will interfere with the amplifier through magnetic fields, electromagnetic induction and circuits, and is a large source of interference for audio power amplifiers. Common interferences include magnetic flux leakage interference, mechanical noise interference and thermal noise interference. So, how to effectively avoid these interference, so that the audio amplifier to obtain excellent sound? Xiaobian will give you a detailed answer.
(1) Magnetic flux leakage interference
Duepin transformerThe magnetic flux leakage itself, if conditions permit, can add a shielding cover on it, the effect is very obvious, and can prevent the magnetic flux leakage to a large extent. It should be noted that the protective cover can only be produced from iron materials. In addition, the use of an external transformer is also a good solution.
(2) Mechanical noise interference
During operation, the iron core vibration caused by the alternating magnetic field will generate mechanical noise, similar to the "hum" emitted by a fluorescent lamp ballast ". Choose high qualitypin transformerIt is an effective way to prevent this mechanical noise. In addition, a rubber damping layer can be installed between the transformer and the fixing plate, or epoxy resin can be injected into the transformer.
(3) Thermal noise interference
Such thermal noise can be addressed by replacing low-noise components or reducing the workload of the components. In addition, reducepin transformerThe working temperature is also one of the effective methods.
Sound amplifier pursuit of perfect sound quality. In order to greatly reduce interference and provide excellent sound quality, you must choose a good quality manufacturer when choosing a pin transformer.
