As the core component of the musical instrument sound system, the universal musical instrument speaker plays an important role in converting electronic signals into sound signals. Its complex and delicate structure ensures that the electronic vibrations generated when the instrument is played can be accurately and vividly converted into real sounds that humans can hear. Below, we will explore the main components of the universal musical instrument speaker in depth.The universal musical instrument speaker is mainly composed of three parts: the vibration system, the magnetic circuit system and the auxiliary system.The vibration system is the core of the speaker, responsible for converting electrical energy into mechanical vibrations, which in turn drives the air to make sounds. This system mainly includes key components such as the diaphragm (also known as the paper cone or diaphragm), the voice coil, the centering support and the dust cover. The diaphragm is the most important vibrating component in the speaker unit. It directly drives the air to make sounds. There are many materials, including paper, glass fiber, carbon fiber, polypropylene, etc. Different materials have different effects on the sound quality. The voice coil is made of round copper wire or aluminum wire, which is wound on the skeleton. When the audio current passes through the voice coil, it will be affected by the force in the magnetic field, thereby generating vibrations. The centering support ensures that the voice coil can be stably maintained in the correct position to prevent deviation, while reducing the weight of the voice coil and improving the overall efficiency of the speaker. The dust cover is located in front of the cone to prevent dust and other foreign objects from entering the speaker and protect the voice coil and magnetic circuit system from contamination and damage.The magnetic circuit system provides the necessary magnetic field environment for the voice coil so that it can vibrate freely and produce sound. This system mainly includes components such as permanent magnets (magnetic steel), T-irons and washers. Permanent magnets are the core part of the magnetic circuit system and provide a strong magnetic field environment. Their materials and performance have an important impact on the sound quality and efficiency of the speaker. T-irons and washers play the role of fixing magnets and basins, and form a uniform magnetic flux loop in the gap between magnets and T-irons.The auxiliary system includes components such as basins, pressure edges, wiring racks and phase plugs, which together support and fix the vibration system and magnetic circuit system to ensure that the speaker can work stably. The basin is usually made of materials such as iron sheets, cast aluminum or plastics. Its rigidity and design have an important impact on the frequency response and sound quality of the speaker.In summary, the structure of the universal musical instrument speaker is complex and delicate, and each part has a specific function and role, which together ensure that the sound produced by the instrument can be accurately and vividly transmitted to the audience.
