Abstract

Provided is a speaker device with which high strength can be obtained for the connection between the outer peripheral region of an edge and the attachment part of a frame, even while reducing the size without sacrificing the breadth of a vibration plate and the edge. This speaker device (10, 20, 30) has: a vibration plate (11, 21) that radiates sound; an edge (12, 22, 32) provided at the outer periphery of the vibration plate (11, 21); a frame (13, 33) provided at the outer periphery of the edge (12, 22, 32) and equipped with an annular attachment part (13a, 33a) to which the outer peripheral region (12b, 22b, 32b) of the edge (12, 22, 32) is connected; and an annular connecting member (17) sandwiched between and adhered to both the outer peripheral region (12b, 22b, 32b) and the attachment part (13a, 33a). The width of the connecting member (17) is greater than the width of the outer peripheral region (12b, 22b, 32b), and the inner diameter of the connecting member is less than the inner diameter of the edge (12, 22, 32).

Description

technical field [0001] The present invention relates to loudspeaker devices. Background technique [0002] Conventionally, for example, a speaker device mounted on audio equipment such as headphones is known (for example, refer to Patent Document 1). Most speaker devices have a diaphragm for emitting sound, a rim provided on the outer periphery of the diaphragm, and a frame provided on the outer periphery of the rim. [0003] figure 1 It is a figure which shows an example of the conventional speaker apparatus. [0004] in the figure 1 In the illustrated speaker device 50 , the outer edge region 51 a of the diaphragm 51 is attached to the inner edge region 52 a of the edge 52 , and the outer edge region 52 b of the edge 52 is connected to a mounting portion 53 a provided on the frame 53 . A flexible portion 52c is provided between the outer edge region 52b and the inner edge region 52c of the edge 52 . Due to the flexibility of the flexible portion 52 c , the vibration p...
