Abstract

PURPOSE:To establish the suitable converter by making the shape of the speaker as ring shape through the use of breathlet or headphone. CONSTITUTION:The support 20 of the vibration plate 17 is placed at a plurality of positions on the substrate 8 of ring shape. The support 20 consists of elastic material. To support the vibration plate 17 to it, a part of the coil bobbin 18 is inserted in the groove 20a formed on the upper surface of the support 20 together with the coil 19, and the coil bobbin 18 is bonded with the support 20 with adhesives. A pair of magnets 21 and 22 are located on the substrate 8 with a given clearance, and between the clearances, the voice coil 19 is placed so that it is not contacted with the magnets 21 and 22.
