Loudspeaker

Abstract

The invention discloses a loudspeaker, and relates to the technical field of electroacoustic products. The loudspeaker comprises a vibration system and a magnetic circuit system; the vibration system comprises a high-pitch vibration assembly at the center position and a low-pitch vibration assembly in the periphery of the high-pitch vibration assembly; the magnetic circuit system comprises U iron, a main magnet is fixed in the U iron, T iron is fixed to the main magnet, and a low-pitch magnetic gap is formed between the main magnet and the sidewalls of the U iron and the T iron; an annular auxiliary magnet is fixed to the T iron, an annular washer is fixed to the auxiliary magnet, a high-pitch magnetic gap is formed between the auxiliary magnet and a central post of the T iron as well as between the washer and the central post of the T iron; a voice coil of the low-pitch vibration assembly is placed in the low-pitch magnetic gap; and a voice coil of the high-pitch vibration assembly is placed in the high-pitch magnetic gap. The loudspeaker of the invention is wide in working frequency band, capable of realizing radiation in full radiation band, high in sound quality, low in assembling difficulty and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of electroacoustic products, in particular to a full-range loudspeaker. Background technique [0002] Loudspeakers, commonly known as horns, are used to convert audio electrical signals into sound and are an energy conversion device. A conventional woofer includes a vibration system and a magnetic circuit system. The vibration system includes a combined diaphragm, voice coil and frame. The magnetic circuit system includes U iron or T iron and magnets and magnets fixed on U iron or T iron in turn. Washer, some speakers will add a secondary magnet to the Washer to enhance the magnetic field strength, improve the sensitivity and high-frequency radiation of the speaker. However, due to the large size of the loudspeaker, the low-frequency radiation ability is strong, and the high-frequency radiation ability is weak. It is difficult to meet the requirements of responding to high and low frequency signals at the s...

AI Technical Summary

Problems solved by technology

However, due to the large size of the loudspeaker, the low-frequency radiation ability is strong, and the high-frequency radiation ability is weak. It is difficult to meet the requirements of responding to high and low frequency signals at the same time. The working frequency band is narrow, which seriously restricts the improvement of its acoustic performance.
