A structure and method for mounting a flat panel speaker are provided which are capable of reliably and accurately positioning a diaphragm in a cabinet and of improving an acoustic characteristic of the flat panel speaker. At least one first protruding portion formed in rectangular portions strikes a first side wall face of a corresponding corner portion of two side walls making up a front case and at least one second protruding portion formed in rectangular portions strikes a second side wall face of a corresponding corner portion of another side wall face of the front case, thus making it possible to properly position the diaphragm relative to the front case and, with the diaphragm being properly positioned, the diaphragm is attached to the front case with the gasket member bonded to the putting-face interposed between the diaphragm and the front case. The diaphragm comes into close contact with the front case in a manner to form a line-like boundary in a contacted portion.

摘要:
An array antenna apparatus includes a first feeding element having a first feed point, a second feeding element having a second feed point, and a first parasitic element electrically connected to the respective first and second feeding elements. In a first frequency band, respective resonances in the feeding elements occur independent of each other, by eliminating electromagnetic mutual coupling between the feeding elements, and exciting the first feeding element through the first feed point as well as exciting the second feeding element through the second feed point. In a second frequency band lower than the first frequency band, a loop antenna having a certain electrical length is formed by the first and second feeding elements and the first parasitic element, and a resonance of the loop antenna substantially occurs by exciting the first feeding element through the first feed point.
摘要:
There is provide a mobile radio apparatus capable of suppressing a mismatching loss, and increasing a transmission/reception sensitivity by means of instantly and adaptively matching the impedance between the antenna and the transmission/reception circuit whatever situation a mobile radio apparatus, such as a mobile phone or the like, may be. In a mobile radio apparatus (1), when starting control of the matching circuit (102), a control section (105) evaluates an initial chromosome stored in a storage section (106), and if there is an initial chromosome for providing an impedance matching, controls the matching circuit (102) so as to have a load value corresponding to this initial chromosome. If there is no initial chromosome for providing the impedance matching, the control section (105) evolves the initial chromosome with a genetic algorithm, derives a chromosome for providing the impedance matching, and controls the matching circuit (102) so as to have a load value corresponding to the derived chromosome.
