摘要: A speaker (100, 700, 100A, 100B) includes a magnet main body (210, 810, 210A, 210B) and a yoke (220, 230, 820, 830, 220A, 220B, 230A, 230B) magnetically linked to a first magnetic pole of the magnet main body. The speaker also includes a diaphragm (400, 400A, 400B) having a vibratory section (410, 410A, 410B), an edge section (430, 430A, 430B), and a rising section (420, 420A, 420B) between the vibratory section and the edge section. A magnetic body (300, 900, 300A, 300B) of the speaker is magnetically linked to the yoke, facing the magnet main body and a voice coil (500, 500A, 500B) is wound around the rising section of the diaphragm. The magnetic body includes an inner shell (330, 330A, 330B), an outer shell (310, 310A, 310B) and a bridge section (320, 320A, 320B) between the inner shell and the outer shell to cover the edge section of the diaphragm. The inner shell of the magnetic body extends from the bridge section along the rising section and the vibratory section of the diaphragm within the inner shell. A magnetic gap (G) is formed between the inner shell of the magnetic body and the magnet main body and the rising section passes through the magnetic gap.

摘要: A planar magnetic transducer (10) having enhanced magnetic structures which increases performance over a single-ended device but mitigates some of the drawbacks of double ended devices, including a supporting structure (30a, 30b), a diaphragm (21) incorporating a coil conductor (27) at least a primary magnetic structure (35a-g), and a secondary magnetic structure (36a-e) can be added, including mitigation of high-frequency resonance and attenuation by providing a more open architecture, including spacing the magnets wider apart, configuring the inter-magnet spaces to provide better acoustic performance, using high-energy magnets, which magnets can be shaped to form at least a part of the shaped inter-magnet space, all of which are directed to obtaining a more efficient and less costly use of magnet material to achieve enhanced performance.

摘要: L'invention se rapporte aux transducteurs électro- acoustiques et plus particulièrement aux microphones dans lesquels la conversion d'une vibration acoustique en tension électrique est assurée par un diaphragme piézo-électrique.
L'invention a pour objet de réaliser en grande série des transducteurs avec un minimum d'éléments qui permettent d'assurer les fonctions d'encastrement du diaphragme (20, 40), de connectique, de blindage, de filtrage acoustique et de protection contre l'humidité et les poussières.
L'invention s'applique notamment à la réalisation de combinés téléphoniques.-
