Problems solved by technology

[0003] However, in the prior art, due to the limitation of the design space, the gap between the sound membrane and the front cover is often small, and the probability of the sound membrane and the front cover correspondingly increases; at the same time, in order to improve the sound effect, the front cover is often designed to be relatively thin , it is easy to produce deformation. After the deformation, the gap between the front cover and the sound film will be smaller, even below the safe distance, but it will cause noise and distortion, which will affect the overall sound effect

Embodiment Construction

[0019] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0020] Refer to figure 1 The speaker of the present invention includes a front cover 10, a basin frame 20, a rear cover 30, a magnetic block 40, a sound film 50, and a voice coil 60 arranged inside the sound film 50. The front cover 10 is provided with a sound outlet 11 in the middle, and the sound film 50 includes a main body portion 51 in the middle and a circle of linkage portions 52 surrounding the main body portion 51. The linkage portions 52 are recessed in the direction of the rear cover 30 relative to the main body portion 51.

[0021] The back cover 30 is fixed on the bottom surface of...

Abstract

The invention discloses a loudspeaker which comprises a front cover, a basin stand, a rear cover, a magnet block, a voice diaphragm and voice coil arranged on the inner side of the voice diaphragm. A voice producing opening is formed in the middle of the front cover, the voice diaphragm comprises a main body part in the middle and a linkage part surrounding the main body part, and the linkage part sinks corresponding to the direction, facing the rear cover, of the main body part. The linkage part on the outer periphery of the voice diaphragm is arranged to be a concave structure, a buffer gap between the front cover and the voice diaphragm is enlarged under the premise that the loudspeaker is integrally unchanged in size and the front cover is not thinned, the probability of voice distortion is effectively reduced, and voice production effect is optimized; meanwhile, a chamfering part is arranged on the inner side, opposite to the linkage part of the voice diaphragm, of the front cover, the thickness of the front cover is not increased while the rigidity of the front cover is guaranteed, and integral reliability of the loudspeaker is improved.

Description

Technical field [0001] The invention relates to the field of electronic sound generating equipment, in particular to a loudspeaker. Background technique [0002] Loudspeaker, also known as "horn", is a kind of transducer device that converts electric signal into acoustic signal. The performance of loudspeaker has a great influence on sound quality. The existing loudspeaker mechanism usually includes a front cover, a sound film, a voice coil, a magnet, and a back cover. The voice coil is fixed inside the sound film, and is arranged together with the sound film and the magnet in the receiving space formed by the front cover and the back cover. When the internal voice coil is energized, the interaction between the voice coil and the magnet drives the sound film to vibrate, so that the sound film produces sound. [0003] However, in the prior art, due to the limitation of design space, the gap between the sound film and the front cover is often small, and the probability of the sound ...
