Novel vibrating diaphragm

Abstract

The invention provides a novel vibrating diaphragm. The vibrating diaphragm comprises a central part, a peripheral part and a folding ring part connected with the central part and the peripheral part,the vibrating diaphragm is characterized in that the folding ring part comprises a first folding ring, a second folding ring and a connecting part which is connected with the first folding ring and the second folding ring and located between the first folding ring and the second folding ring, and the first folding ring comprises a first edge end connected with the center part and a second edge end connected with the connecting part; the second folding ring comprises a first peripheral end connected with the connecting part and a second peripheral end connected with the peripheral part; and the first folding ring and the second folding ring bulge towards the same direction. Compared with the vibrating diaphragm in the prior art, the vibrating diaphragm has obvious difference in structure,specifically, the folding ring part is divided into the first folding ring and the second folding ring, and the folding ring part formed by the two parts can have higher amplitude in a state that thewidth of the whole folding ring part is relatively low, so that the corresponding acoustic performance requirement is met.

Description

【Technical field】 [0001] The invention relates to the technical field of loudspeakers, in particular to a novel diaphragm. 【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 performance of the speaker directly affects the sound output effect of the mobile terminal device that cooperates with it. 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. It can be seen from the above description that the diaphragm is one of the key components for the speaker to vibrate and produce sound. [0003] The loudspeaker diaphragm in the prior art includes a central part ...

Problems solved by technology

With the improvement of product quality requirements, one design idea is to reduce the width of the U-shaped runway ring, that is, to limit the overall width of the U-shaped runway ring to a smaller range, but based on the same material, this The adjustment of the structural specifications will cause the U-shaped runway ring to have insufficient amplitude in actual use and cannot meet the corresponding acoustic effect requirements
