Loudspeaker is an important output device for high-frequency sound signals, mainly used to convert high-frequency signals processed and amplified by audio signal processing and power amplifiers into audible sound. High pitched speakers are commonly used in high-quality audio systems, theaters, and projection halls to provide their users with a high-quality auditory experience. In this article, we will briefly introduce the structure and working principle of a loudspeaker.
A loudspeaker consists of three main parts: diaphragm, magnetic field, and housing. High pitched speakers typically have two diaphragms, one for producing sound and the other for protecting the magnetic field from contamination and damage. The diaphragm is the core part of a high-frequency speaker that vibrates and produces sound, usually made of polyester film, aluminum foil, or silk material. The diaphragm of a tweeter is relatively small, allowing it to produce sound at high frequencies.
The magnetic field of a tweeter is another key component of its structure. A magnetic field typically consists of one or more large permanent magnets and several magnetic cores, which can be placed inside a quasi dense processed magnetic field enclosure to ensure its accuracy and performance. Long term magnets are usually made of neodymium iron boron or cobalt magnets, which have high magnetic field strength and stability, which are crucial for the sound quality of high-frequency speakers.
The casing of a tweeter is usually made of plastic or metal, designed to provide sufficient mechanical support and protect internal components. The casing can also be optimized according to design requirements to provide excellent sound performance and reliability in different situations. Some high pitched speakers use special materials and design techniques, such as sandwich diaphragms, low torque magnetic circuits, and special shapes, to improve their performance and sound quality.
In terms of the working principle of high-frequency speakers, when the audio signal is amplified by a power amplifier, the diaphragm of the high-frequency speaker begins to resonate, which can generate a set of periodic vibrations. Because the vibration speed of high pitched speakers is very high, it leads to faster air compression. When the air pressure gradually returns to normal levels, these oscillating waves will diffuse into the air and propagate in the form of sound.
In short, as an important component of the audio system, the reasonable design of the structure and working principle of the tweeter has a decisive impact on the performance of sound quality. For manufacturers and users, understanding the basic principles of the structure and working principle of tweeters is crucial, as it will help them better choose and use high-quality audio equipment.
