Loudspeaker and electronic equipment with loudspeaker

Abstract

The invention discloses a loudspeaker including a loudspeaker base, supporting plates are fixedly installed on the two sides of the loudspeaker base. A cylindrical permanent magnet is fixedly installed in the middle of the loudspeaker base. A coil is movably inserted into the cylindrical permanent magnet; the periphery of the dome is connected with an annular vibrating diaphragm; the other end ofthe annular vibrating diaphragm is fixedly connected to the rectangular frame; the supporting plates on the two sides are each provided with a pair of supporting blocks. Permanent magnets are fixedlymounted at the bottoms of the supporting blocks; one end, far away from the permanent magnet, of the induction coil is fixedly mounted on the rectangular frame; according to the invention, the electromagnetic coils are oppositely arranged, the loudspeaker can synchronously approach or move away under the action of alternating current, effectively solves a problem that the unidirectional amplitudeof a conventional loudspeaker exceeds a linear stretching range under the conditions of high volume and high power, is high in bass diving depth, improves the vibration stability of the diaphragm through cooperating with the reverse vibration units arranged at four corners, and effectively reduces the noise of a high range.

Description

technical field [0001] The invention relates to the technical field of loudspeaker structures, in particular to a loudspeaker and electronic equipment with the loudspeaker. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest device in the audio equipment, and for the sound effect, it is the One of the most important components, there are many types of speakers, and the price varies greatly. Audio power uses electromagnetic, piezoelectric or electrostatic effects to make its paper cone or diaphragm vibrate and resonate with the surrounding air (resonance) to produce sound. In the existing loudspeakers, the dome is generally installed on the diaphragm to form a vibration device. The vibration device is driven by the voice coil to reciprocate, and then vibrates to produce sound. Most of the diaphra...

[0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great influence on the sound quality. The loudspeaker is the weakest device in the audio equipment, and for the sound effect, it is the One of the most important components, there are many types of speakers, and the price varies greatly. Audio power uses electromagnetic, piezoelectric or electrostatic effects to make its paper cone or diaphragm vibrate and resonate with the surrounding air (resonance) to produce sound. In the existing loudspeakers, the dome is generally installed on the diaphragm to form a vibration device. The vibration device is driven by the voice coil to reciprocate, and then vibrates to produce sound. Most of the diaphragms in the market are composed of multiple layers of thin films. The material is composite, and the elastic linear range of the diaphragm is small when vibrating, which is prone to unbalanced vibration, and exceeds the linear stretch range when the amplitude is large, resulting in high distortion, which in turn affects the quality of audio output, and cannot be applied to the needs High power and loud audio output
