381352000 | Having internal wave reflecting means | 11 |
20090147980 | NARROW PROFILE SPEAKER CONFIGURATIONS AND SYSTEMS - A narrow profile speaker unit comprises at least one speaker outputting sound towards an internal surface and through a duct with an output terminus, such as a slot, having a narrow dimension, effectively changing the cross-section of the speaker's audio output wave. A pair of speakers may face one another, outputting sound towards a common output slot. Multiple pairs of speakers may be used to form an inline speaker unit for increased sound output. A slotted speaker unit may include multiple speakers facing the same direction, towards a groundplane or reflecting surface, and having parallel apertures for allowing sound radiation. The speaker units may be integral with or attached to electronic appliances such as desktop computers or flatscreen devices, or may be used in automobiles or other contexts. | 06-11-2009 |
20090323997 | Horn-loaded acoustic line source - A sound reproduction system is disclosed in which a sound enclosure defines a soundwave path having a first end, a second open end and at least one bend therebetween. At least one driver is provided at the first end for producing a driver soundwave that is confined by the sound enclosure for travel along the soundwave path. At least one baffle member is situated in the soundwave path, defining a reflective surface of preselected shape that reflects and constricts the soundwave therethrough. | 12-31-2009 |
20100290659 | LOUDSPEAKER ASSEMBLY AND ELECTRONIC EQUIPMENT - A loudspeaker assembly includes a loudspeaker located at the position of one of the focuses of a reflector, whose over-internal wall section constitutes a part of an ellipse, in such a manner that the sounds-releasing surface of the loudspeaker is oriented to be opposite to the internal wall surface of the reflector. | 11-18-2010 |
20110096951 | VARIABLE DIRECTIONAL MICROPHONE ASSEMBLY AND METHOD OF MAKING THE MICROPHONE ASSEMBLY - A variable directional microphone assembly and method of manufacturing the variable directional microphone assembly which includes a substrate, a semiconductor integrated circuit device, two microphone devices, a microphone body, and a case. | 04-28-2011 |
20120020511 | MICROPHONE POP FILTER - A microphone pop filter for attenuating plosive artifacts utilizes a substantially acoustically transparent material configured to define multiple airfoil surfaces that are oriented non-orthogonally relative to an axis defined between an audio source and a microphone diaphragm, with the substantially acoustically transparent material disposed intermediate the audio source and the microphone diaphragm and separated from the microphone diaphragm by an airspace. Plosive artifacts from the audio source may be deflected away from the microphone diaphragm by the airfoil surfaces to reduce the impact of such artifacts on the microphone diaphragm and the resulting electronic signal output therefrom. | 01-26-2012 |
20140198941 | ACOUSTICAL SIGNAL GENERATOR USING TWO TRANSDUCERS AND A REFLECTOR WITH A NON-FLAT CONTOUR - The present invention relates to an audio generator comprising, a first and a second transducer element, and the first transducer element has a first membrane having a surface which is non-flat, and a reflector, wherein the reflector has a surface with a non-flat contour and the reflector co-operating with directive guiding walls so as to lead and guide audio pressure waves to propagate in predetermined directions. | 07-17-2014 |
20150098601 | APPARATUS FOR ENHANCING SOUND FROM PORTABLE DEVICES - An apparatus is disclosed for enhancing the sound level of portable devices by providing a sound reflector between the portable device and a case. The sound reflector includes a shield which functions to redirect output from rear facing speakers toward the front. The sound reflector can be extended for redirecting sound or retracted when not in use. A case incorporating a retractable sound reflector is also disclosed. | 04-09-2015 |
20150104055 | BRANCHED ACOUSTIC DEVICE - An acoustic device configured for use with an audio source. The acoustic device includes a stem portion and multiple branches forming a cavity for passage of an audio signal when connected to an audio source. An array of multiple acoustic devices or nodes may be physically connected to form a tree-like structure for providing amplified sound in an aesthetically and tonally pleasing manner which fills its surrounding with sound. In view of the physical connectability of the individual nodes, an audio outputting device may be form which is easily modified, scaled, and/or re-configured to adjust its tonal properties and directionality. | 04-16-2015 |
20150110327 | Speaker Back Cavity - An apparatus including a sound transducer; and a housing having the sound transducer connected thereto. The housing forms a substantially sealed air space back cavity acoustically coupled to the sound transducer. The housing includes a housing member having a first dividing structure located in the back cavity to connect two adjacent air mass sections of the back cavity, where the dividing structure includes at least one aperture to permit travel of sound waves through the at lease one aperture between the air mass sections. | 04-23-2015 |
20160044403 | SPEAKER CABINET - Speaker Cabinets are provided. In one embodiment, a speaker cabinet comprises: a core fabricated from a core material, the core material having an inner chamber defining an air cavity internal to the core; a baffle board having an internal side and an external side, wherein the internal side is mounted to the core at an opening to the air cavity; and a plurality of baffle board sonic coupling battens extending from the baffle board into the core material of the core. | 02-11-2016 |
20160088385 | SHUTTER COVERED ON SOUND HOLE OF LOUDSPEAKER MODULE AND ASSEMBLING METHOD THEREOF, LOUDSPEAKER MODULE - A blocking piece covering the sound hole of a loudspeaker module may be arranged at a position where the sound hole is located on the case of the loudspeaker module and covers the sound hole. The blocking piece may be made of a nonmetallic flexible net. The nonmetallic net-shaped blocking piece and the case may be formed integrally by injection moulding. The loudspeaker module and the blocking piece covering the sound hole thereof in the present invention may provide good acoustic performance, high reliability, high space utilization rate and/or high production efficiency. The assembling method for the blocking piece covering the sound hole of the loudspeaker module further makes the assembling of the blocking piece convenient for operation, and improves the assembling efficiency and assembling quality. | 03-24-2016 |
