Embodiment Construction

[0013] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0014] refer to figure 1 and figure 2 , the electroacoustic conversion device of the present embodiment is a speaker 50 . In addition to the speaker 50, the figure shows a housing 90 to which the speaker 50 is attached and a double-sided tape 91 for this attachment. As shown in the figure, the speaker 50 can be attached so as to close the opening N9 provided in the housing 90 . Speaker 50 has diaphragm 10 , frame 20 , frame cover 30 (mounting member), fixing member 40 , voice coil 22 , magnet 24 , plate 25 , and yoke 26 . The housing 90 is, for example, a housing of an electrical device such as a mobile phone.

[0015] The vibrating plate 10 has an edge portion 11 and a vibrating vibrating portion 12 surrounded by the edge portion 11 . The vibrating plate 10 is formed impermeable to water, for example, made of synthetic resin. As a synthetic resin, PET (polyethyl...

Abstract

A frame has a diaphragm's edge attached thereto. An attachment member has a frame portion and a hook. The frame portion has a first plane to be bonded to a casing, and a second plane opposite to the first plane. The hook is supported by the frame portion and also opposite to the second plane with a gap interposed. The frame at the portion having the diaphragm's edge attached thereto is fitted into the gap. A securing member secures the edge and the second plane together.

Description

technical field [0001] The present invention relates to an electro-acoustic conversion device, in particular to an electro-acoustic conversion device with a vibrating plate. Background technique [0002] Electrical audio converters are mounted on electrical equipment such as mobile phones. An electroacoustic conversion device refers to a device that converts electrical signals and audio signals, such as speakers or microphones. A general electroacoustic transducer has a vibration plate whose edge is fixed to a frame. When high waterproofness is required for the electroacoustic transducer, it is preferable to prevent water leakage between the edge of the diaphragm and the frame by making them adhere to each other. [0003] According to Japanese Unexamined Patent Publication No. 2009-004821, there is disclosed a structure in which a waterproof seal is provided between a housing and a speaker mounted thereon. A protrusion that comes into contact with the edge of the diaphrag...
