Abstract: A speaker apparatus, in which sound wave is uniformly radiated to front and rear sides thereof, to prevent distortion of sound due to one way vibration. The speaker apparatus includes a bobbin to vibrate a vibrating plate according to a current applied to a voice coil, and a yoke is disposed at an inner side of the bobbin and spaced apart from the bobbin by a predetermined interval. A sound wave guiding member is disposed at an inner side of the yoke so as to guide the sound wave to the front side and the rear side of the speaker apparatus.

Abstract: A speaker apparatus, in which a middle-high frequency speaker is disposed forward of a low frequency speaker. First and second sound guiding member are disposed in front of the low frequency speaker and middle-high frequency speaker improving low sound while reducing noise and distortion. The speaker includes a yoke having a path arranged at rear side of a woofer with the first sound guiding member disposed in the yoke for guiding sound discharged through the path. A tweeter is disposed at the front end of the first sound guiding member. A partition wall is disposed at the edge of the tweeter for separating middle-high frequency sound from low sound radiated from the woofer, and the second sound guiding member is disposed at the central portion of the tweeter.

Abstract: A technique for judging the tire width and tread of a vehicle includes: a switch array including common contact points lying across a vehicle pass way, the common contact points being formed of a strip-shape conductor, and a plurality of individual contact points arranged in an equal distance, disposed on a plane parallel to and adjacent to a plane of the common contact points and having a predetermined distance therebetween, the individual contact points coming into contact with the common contact points when treading pressure is applied thereto; an interface for latching and shifting state data of each individual contact point in a predetermined scanning cycle; a data memory for storing the state data of each individual contact point, transmitted by the interface; a program memory for storing a system program for judging the tire width and tread of a vehicle; and a processor for processing the state data of individual contact points, stored in the data memory, using the system program stored in the program

Abstract: A symbol decoding apparatus run-level-decodes corresponding symbol data using the same scan pattern data as used for run-level-encoding. A symbol separator separates the received run-level-encoded symbol data into run data and level data. An address outputter selects a particular scan pattern using the scan pattern data associated with the symbol data, and selects a scan address for storing the level data among the scan addresses corresponding to the selected scan pattern using the separated run data. A data store stores the level data supplied from the symbol separator at the storage position designated by the selected scan address. Thus, the run-level-encoded symbols are run-level-decoded based on the scan pattern used for run-level encoding and stored in a form appropriate for use in a downstream unit.

Abstract: A loudspeaker system capable of minimizing interference of sound waves and increasing bass sound amplification efficiency by collecting and amplifying only a portion of the sound waves radiated from the rear of a loudspeaker. The loudspeaker system includes a supporting member having a partition formed therein, an amplifying horn for collecting and amplifying only a portion of the sound waves radiated from the rear of a loudspeaker, a discharge horn for discharging the amplified sound waves, and a guide plate for guiding the sound waves discharged from the loudspeaker and through the discharge horn.

Abstract: A speaker system for a television includes a speaker provided in the television; a front amplifying member for amplifying sound waves radiated forward of the speaker; and a rear amplifying member for amplifying a portion of sound waves radiated rearward of the speaker. The rear amplifying member comprises a sound collecting part for collecting a portion of sound waves radiated rearward of the speaker, and a first and second amplifying horn halves detachably assembled each other to define an amplifying part of the rear amplifying member.
