Patent number: 8925676Abstract: Speaker performance can be improved by routing sound from a rear side of speaker through a circuitous port formed between inner and outer surfaces of a wall of the speaker enclosure. An audio speaker enclosure comprises an enclosure housing defining an internal volume with a speaker opening at a first end thereof, the speaker opening being configured to receive a speaker therein, the enclosure housing having an inner surface facing the internal volume and an outer surface, the enclosure further defining at least one port communicating between the internal volume and the outer surface, the at least one port extending between the inner and outer surfaces along a port length that is greater than a maximum housing thickness between the inner and outer surfaces. The speaker enclosure can be made by arranging an inner speaker enclosure shell within an outer speaker enclosure shell such that the port is defined therebetween.Type: GrantFiled: June 7, 2013Date of Patent: January 6, 2015Inventor: Jimmy Lee Murray

Patent number: 8873788Abstract: A sub woofer for in-ground installation and a method of installation. The sub woofer has a cylindrical enclosure or housing having a driver, electronics and a band pass filter. The driver cone is coaxial with the axis of the cylindrical housing. A port tube assembly having a tuned port tube and a resilient elbow interface is attached to an end wall of the housing in an eccentric position with the port tube projecting vertically and terminating at a canopy. The installation requires placing the enclosure in an excavation and positioning the housing and port assembly so a predetermined above ground spacing exists between the upper end of the above ground port tube and grade.Type: GrantFiled: August 29, 2011Date of Patent: October 28, 2014Inventor: Jeffery James Coombs

Patent number: 8757317Abstract: The present invention is to provide a loudspeaker enclosure structure which includes a hollow housing being a barrel-shaped housing whose outer surface is concavely provided with a plurality of directional grooves each evenly arranged along the circumferential direction of the hollow housing and extending from the front end to rear end of the hollow housing, and a reflective cover having a front side fixed to a rear opening of the hollow housing and concavely provided with an annular reflective groove adjacent to the periphery of the reflective cover. The hollow housing has a receiving space therein which is in communication with each directional groove through the reflective groove. Therefore, the sound generated by a loudspeaker fixed in the receiving space will not only propagate out of the front end of the hollow housing, but also be transmitted to the space surrounding the hollow housing by way of the directional grooves.Type: GrantFiled: May 3, 2013Date of Patent: June 24, 2014Assignee: Longinesteno Technology Complex CorporationInventor: Chao-Lang Wang

Patent number: 8749394Abstract: Various inventive features are disclosed for efficiently generating regulation-compliant audible alerts, including but not limited to 520 Hz square wave alert/alarm signals, using an audio speaker. One such feature involves the use of a non-linear amplifier in combination with a voltage boost regulator to efficiently drive the audio speaker. Another feature involves speaker enclosure designs that effectively boost the output of the audio speaker, particularly at relatively low frequencies. These and other features may be used individually or combination in a given alarm-generation device or system to enable regulation-compliant audible alerts to be generated using conventional batteries, such as AA alkaline batteries. Various examples of efficiently generated regulation-compliant audible alerts and further enhancing such audible alerts by utilizing speaker enclosure designs are provided.Type: GrantFiled: February 9, 2010Date of Patent: June 10, 2014Assignee: InnovAlarm CorporationInventors: James J. Lewis, Landgrave T. Smith, David E. Albert

Patent number: 8627919Abstract: A speaker has a speaker unit and a box. The speaker unit has a speaker unit side terminal. The box includes a casing having an internal space, and a box side terminal arranged in the casing so as to be in close contact with the casing. Under the condition that the speaker unit is housed in the internal space, a first terminal serving as one of the speaker unit side terminal and the box side terminal has a projection, a second terminal serving as the other thereof surrounds and sandwiches an outer periphery of the projection from at least both sides, and the first terminal and the second terminal are electrically connected with soldering. Thus, it is possible to obtain the speaker which can improve workability on a connection between the speaker unit and the box and save a space, and the portable information terminal provided with the speaker.Type: GrantFiled: December 21, 2011Date of Patent: January 14, 2014Assignee: SANYO Electric Co., Ltd.Inventor: Hideki Hiwatashi

Patent number: 8477967Abstract: A speaker assembly is provided with a housing, a speaker mounted to the housing, and a reflector spaced apart from and facing the speaker. The reflector is symmetrical and has an arcuate central convex region for reflecting pressure back to the speaker for amplifying back pressure to the speaker. The reflector has a secondary region with an arcuate cross-section for reflecting acoustic vibrations past and outboard of the housing. The reflector is partially translucent, and a light source is provided adjacent the reflector for conveying light to the reflector, past and outboard of the housing for illuminating a region that receives acoustic vibrations reflected from the reflector. A media assembly is provided with a fan operably connected to a generator so that air that passes into a housing through an inlet and out of an outlet, causes the fan to rotate thereby providing a power source to a media device.Type: GrantFiled: December 19, 2011Date of Patent: July 2, 2013Inventors: Ronald Paul Harwood, Kenneth Alan Klemmer, Larry Alan Schirmer
