Patent number: 9042593Abstract: A protective portion is provided on a lower surface of a sound reproducing device, and has a protective wall that restrains a deformation of a terminal in a direction different from an elastic deformation direction of the terminal. The terminal includes a restrained portion in which the deformation is restrained with the protective wall. The restrained portion is provided at at least one of a position closer to a base than a feeding portion of the terminal and a position closer to a tip portion of the terminal than the feeding portion. The protective wall extends along the restrained portion. This configuration can suppress a plastic deformation of the terminal even when a force in the direction different from the elastic deformation of the terminal is applied to the terminal.Type: GrantFiled: December 19, 2012Date of Patent: May 26, 2015Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Tomoyuki Matsunaga, Kazuki Honda, Kazuyuki Kosuda, Shigeru Tomoeda

Patent number: 7877856Abstract: An edge (29) for supporting a diaphragm assembly (100) with respect to a frame (26) is bonded to the frame (26) along the outer periphery thereof and joined to a diaphragm (27) in a position more peripherally inward than a voice coil (28) along the inner periphery thereof. The edge (29) partly overlaps diaphragm (27). This structure allows downsizing of the speaker, without reducing the sizes of a permanent magnet (21) and the edge (29).Type: GrantFiled: May 12, 2009Date of Patent: February 1, 2011Assignee: Panasonic CorporationInventors: Takanori Fukuyama, Tomoyasu Takase, Koji Sano, Hiroshi Yano, Masanori Nakano, Shigeru Tomoeda, Kazuki Honda, Kazuya Yamasaki, Kazutaka Kubo, Takeshi Shimokawatoko, Mitsutaka Enomoto, Masahide Sumiyama

Patent number: 7388964Abstract: A loudspeaker is provided that satisfies requirements for both a small size and a high sound pressure. In addition, the heat capacity of the magnetic circuit and the heat dissipation of the voice coil are improved in this loudspeaker. Using at least two pieces of bar magnets (21), an outer magnet type magnetic circuit is structured in which the magnetic gap comprising an upper plate (22) and a lower plate (23) has a straight section. Also, the configuration of the voice coil (28) is that of a track.Type: GrantFiled: January 27, 2004Date of Patent: June 17, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Shigeru Tomoeda, Takanori Fukuyama, Masahide Sumiyama

Patent number: 7362877Abstract: An electro-acoustic transducer wherein a stopper of a terminal is composed of an elastic body having an impulsive-force resistance and an excellent resilience. The stopper is mounted on the yoke or lower plate of magnetic circuit, which is made of a metallic material having an impulsive-force resistance. In this way, the stopper can restrict the terminal within the reversibility limit value of the spring force of the metallic material, and hence can enhance the reliability.Type: GrantFiled: April 27, 2005Date of Patent: April 22, 2008Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Kazuki Honda, Koji Sano, Kazutaka Kubo, Kazuya Yamasaki, Hiroshi Yano, Takeshi Shimokawatoko, Takanori Fukuyama, Shigeru Tomoeda, Mitsutaka Enomoto, Masahide Sumiyama

Patent number: 7113813Abstract: A portable communication terminal employs an electro-acoustic transducer having openings on the housing. The openings of the transducer are coupled to a housing of the terminal or acoustic pipes unitarily formed with the housing of the transducer. An opening of the acoustic pipe faces an opening provided in the housing of the terminal. The terminal uses a transducer including a diaphragm, a cover closely jointed to an outer periphery of the diaphragm and facing a front face of the diaphragm, and a frame provided at a rear face of the diaphragm. The terminal and the transducer consume less power and yet radiate greater output sound pressure with smaller bodies. They can deliver sound from a display section, so that a user accepts the sound normally.Type: GrantFiled: July 10, 2002Date of Patent: September 26, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takeshi Shimokawatoko, Shigeru Tomoeda, Koji Sano, Tetsuya Mori, Kazutaka Kubo
