Patent number: 8520882Abstract: A speaker terminal mount structure has a frame having a slit, and a terminal supported by the frame when inserted into the slit. The slit has a shape including two first side support sections, and at least one second side support section abutting on a second surface and positioned on an inner side of a region sandwiched between the two first side support sections when viewed from a direction in which the terminal is inserted. Assuming that a first virtual straight line is formed by connecting the two first side support sections, and a second virtual straight line extends in parallel to the first straight line at a distance smaller than a thickness of the terminal from the first straight line in a first direction, the second side support section is positioned in a second direction with respect to the second straight line.Type: GrantFiled: January 20, 2012Date of Patent: August 27, 2013Assignee: SANYO Electric Co., Ltd.Inventor: Hideki Hiwatashi

Patent number: 8130976Abstract: A sound system which has, for example, a radio, a cassette and a CD player is usually already installed in cars as standard or as an option. In addition, a better sound system includes a box system which has a tweeter and a woofer. In order to provide a speaker box which is suitable particularly for dispensing frequencies below 150 Hz and at the same time has neat pulses accompanied at the same time by little distortion, pulse dynamics and is highly effective, a sound transducer (10) is introduced into the supporting structure of the vehicle. This takes place in such a manner that subcompartments which are separated from each other adjoin each of its two membrane sides. In this case, the two subcompartments of the speaker box are formed by at least two elements (2, 3, 4) of the supporting structure of the vehicle (1).Type: GrantFiled: February 1, 2007Date of Patent: March 6, 2012Assignee: Daimler AGInventors: Klaus Linhard, Norbert Niemczyk
