Title:
DIAPHRAGM AND ELECTROACOUSTIC TRANSDUCER
Document Type and Number:
WIPO Patent Application WO/2019/128422
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a diaphragm and an electroacoustic transducer. The diaphragm is rectangular and comprises a middle part and a folding ring part surrounding the periphery of the middle part. The folding ring part comprises two opposite first side parts, two opposite second side parts, and arc-shaped corner parts located between the first side parts and the second side parts; the arc-shaped corner parts form corner areas together with the ends of the first side parts and the ends of the second side parts which are connected to the arc-shaped corner parts; each corner area of the folding ring part is provided with a first pattern group and a second pattern group which are adjacent to each other; each of the first pattern group and the second pattern group comprises a plurality of single patterns; the plurality of single patterns of the first pattern group is provided to diverge from the outer side to the inner side of the folding ring part, and the plurality of single patterns of the second pattern group are provided to diverge from the inner side to the outer side of the folding ring part. The technical solution provided by the embodiments of the present invention enables a diaphragm to meet temperature requirements in different operating modes, has an effective inhibiting effect on harmonic distortion, and can also improve the audition quality and the acoustic performance of an electroacoustic transducer.
