Patent number: 11089393Abstract: A loudspeaker system includes a housing including a first housing portion and a second housing portion that are plate-shaped and face each other, a loudspeaker drive unit fixed to the first housing portion, and a coupling member that is rigid and couples the first housing portion and the second housing portion to each other inside the housing. The coupling member includes a first end that is directly or indirectly coupled to the first housing portion and a second end that is directly or indirectly coupled to the second housing portion. When second force is applied to the coupling member, the second force being smaller than first force that irreversibly deforms or breaks a coupling portion between the coupling member and the first housing portion, the coupling member is irreversibly deformed or broken so as to shorten a distance between the first end and the second end of the coupling member.Type: GrantFiled: December 19, 2019Date of Patent: August 10, 2021Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Keisuke Fujimoto, Koji Sano, Yasunori Miyamoto, Teppei Koido

Patent number: 10979833Abstract: An acoustical performance evaluation method includes a reference sound pressure decision step and a deviation calculation step. In the reference sound pressure decision step, frequency response of sound pressure level, obtained by considering only an influence of a first factor of a plurality of factors causing a deterioration in frequency response of sound pressure level of a loudspeaker to be evaluated, are decided as a reference sound pressure. The reference sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment. In the deviation calculation step, a deviation between the reference sound pressure and a target sound pressure is calculated as an evaluation index of acoustical performance. The target sound pressure is frequency response of sound pressure level of the loudspeaker in the anechoic chamber calculated through a simulation or measured through a measurement experiment.Type: GrantFiled: December 3, 2019Date of Patent: April 13, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Yasunori Miyamoto, Keisuke Fujimoto
