Patent number: 9058799Abstract: Sound diffusers are important components in enhancing the quality of room acoustics. The present disclosure relates to a sound diffuser obtained by using properties of the cymatics phenomena. Cymatics is the study of sound and vibration made visible, typically on the surface of a plate, diaphragm or membrane. Two examples of diffusers are designed by the cymatic shapes and modeled by using a quadratic quadratic residue sequence. It is found that this type of acoustic diffusers can be used to maintain the acoustic energy in a room and at the same time can treat unwanted echoes and reflections by scattering sound waves in many directions. The design allows for creating different interior space designs by changing the arrangement of the diffuser panels, and this leads to different applications for the diffusers.Type: GrantFiled: May 15, 2014Date of Patent: June 16, 2015Assignee: University of DammamInventors: Alaa Salman Abdullah Algargoosh, Hany Elsayed Ali Hossameldin, Hala Abdelmonem Mohmoud El-Wakeel

Patent number: 8967323Abstract: The enclosure comprises a seven-sided prism on which loudspeakers or other devices for sound reproduction are mounted at a substantial angle to each other. Using its primary base, speakers are angled obliquely upward. Speakers mounted on the enclosure can share a single audio signal. Multiple signals can be sent to speakers on different sides of the enclosure. It can be used as a double floor monitor, a wide-dispersion main speaker, a simultaneous combination of double floor monitor and audience-facing main speaker, or a combination of wide dispersion main speaker and a single floor monitor. It reduces the number of speaker enclosures necessary for a stage production. It can be manufactured simply and affordably from many materials using standard construction methods. The enclosure may be useful for any other application where it may be advantageous, including but not limited to, audio speakers for computer, television, radio, or music playback.Type: GrantFiled: December 3, 2013Date of Patent: March 3, 2015Inventor: James Robert Grenier

Patent number: 8953830Abstract: A horn loudspeaker, in particular for reproducing bass sound in public address systems, in which the horn (23) is mounted directly to the driver element (21) without any intervening compression chamber. The back side of the driver element (21) is covered by a back chamber (24) designed with walls of a semi-permeable material. The walls may be perforated or made of a “leaky” material such as cell foam with open structure, or a fibrous material. The “leaky” back chamber will prevent the build up of high pressures in the back chamber at large cone excursions. The horn loudspeaker is suitable for stacking in groups of two or more, so as to produce a sound source scalable for reproducing any frequency range heard by humans in public address systems or hi-fi systems. Due to the back chamber design, the horn loudspeaker, for high frequencies especially in conical horn shaped versions, can be stacked close together.Type: GrantFiled: August 21, 2007Date of Patent: February 10, 2015Inventor: Rune Skramstad

Patent number: 8891805Abstract: A speaker apparatus selects a path which emits a speaker sound. The speaker apparatus includes a speaker unit for outputting the sound generated from voice data, a body including at least one or more emission paths for guiding and emitting the sound output from the speaker unit, and a member for opening or shutting out at least one emission path.Type: GrantFiled: April 5, 2012Date of Patent: November 18, 2014Assignee: Samsung Electronics Co., Ltd.Inventors: Jung-Eun Han, Jang-Hoon Kang, Ki-Won Kim

Patent number: 8851229Abstract: A compressor assembly that has a compressed air tank having a vibration absorption member. The vibration absorption member can exert a pressure on a portion of the compressed air tank. A method of controlling sound emitted from a compressor assembly, by using a vibration absorber which applies a force against the compressed gas tank. Controlling the sound level of the compressed gas tank is accomplished by absorbing vibration from the compressed gas tank by which exerting a pressure on a portion of the compressed gas tank.Type: GrantFiled: September 11, 2012Date of Patent: October 7, 2014Assignee: Black & Decker Inc.Inventors: Stephen J. Vos, Scott D. Craig

Patent number: 8844671Abstract: An apparatus for damping sound in the optical beam path of a microscope, having an acoustic insulation housing for encapsulating a sound-emitting component, preferably a rapidly moving or oscillating beam deflection means, in particular a resonantly oscillating mirror, the housing comprising at least one optical entrance/exit opening, is characterized in that the housing, preferably the opening of the housing, is embodied and/or configured in such a way that the sound otherwise emerging from the housing is largely extinguished by destructive interference without thereby influencing the optical beam. A microscope having a corresponding apparatus is furthermore claimed.Type: GrantFiled: May 15, 2013Date of Patent: September 30, 2014Assignee: Leica Microsystems CMS GmbHInventors: Holger Birk, Volker Seyfried, Dirk-Oliver Fehrer, Vishnu Varden Krishnamachari
