Novel vibrating diaphragm and loudspeaker

Abstract

The invention provides a novel vibrating diaphragm, and relates to the technical field of loudspeaker products. The vibrating diaphragm comprises a vibrating plate and a flexible plate adaptive to andattached to the vibrating plate. The vibrating plate comprises a spherical top part, a folding ring part annularly arranged on the periphery of the spherical top part and an extension part annularlyarranged on the outer side of the folding ring part, and the folding ring part protrudes towards the side away from the vibrating plate and attached to the flexible plate. The flexible plate comprisesa center plate used for providing rigidity, a frame part attached to the extension part and a plurality of supporting strips connected between the center plate and the frame part. An annular cavity is formed between the central plate and the frame part. The supporting strips are arranged in the annular cavity, and the center plate, the frame part and the supporting strips are arranged in a coplanar mode. The plurality of supporting strips are connected and supported between the central plate and the outer frame part which is attached to the extension part of the vibrating plate, so that the supporting strips are in a linear state and are not easy to generate resonance when the vibrating diaphragm works, and the vibrating plate and the flexible plate are stably attached, so that the overall sensitivity is improved. The invention further provides a loudspeaker.

Description

technical field [0001] The invention relates to the technical field of loudspeaker products, in particular to a novel diaphragm and a loudspeaker. Background technique [0002] As a device that can convert electrical energy into sound energy, the speaker has been widely used in mobile terminals such as mobile phones, computers, and PADs. The conventional structure of the loudspeaker generally includes a magnetic circuit system and a vibration system. The vibration system also includes a diaphragm and a voice coil. The diaphragm vibrates, and then radiates sound waves to the outside world, thereby completing the conversion of electrical energy into sound energy. Therefore, the diaphragm is one of the key components for the speaker to vibrate and produce sound. [0003] The diaphragms at this stage mainly include silicone diaphragms and plastic diaphragms, and plastic diaphragms are usually composed of single-layer or multi-layer plastic films. Regardless of whether it is a...
