Patent number: 8729378Abstract: As described herein, a sound pickup for musical cymbals includes an integrated assembly attachable to a cymbal stand. The integrated assembly includes a plurality of microphones arranged and electrically connected such that the resulting amplified sound is of optimal quality and of relatively constant loudness regardless of cymbal tilt. In one embodiment, two microphones are used, with the signal phase from one microphone being inverted prior to combination with the signal from the other microphone. The inversion is implemented using an inverter and serves to cancel signals that are in phase with one another and augment signals that are out of phase with one another. This, along with suitable placement of the pickup, exploits the fact that the more desirable components of the cymbal's vibration at the inflection point of the cymbal are out of phase with each other, whereas the less-desirable components are in phase with each other.Type: GrantFiled: September 14, 2011Date of Patent: May 20, 2014Assignee: Avedis Zildjian Co.Inventors: Christopher Ryan, Julia D.

Publication number: 20130243233Abstract: An air cushioned microphone cable retractor and receptacle assembly for use in controlling the deployment and retraction of a limited length of microphone cable includes a hollow cylindrical housing portion, in which a pulley mounted to a piston is disposed. A microphone cable is connected to the pulley, and then to the microphone, which is configured to reside in a top receptacle when not in use. In use, the microphone may be pulled out and away from the receptacle, at which time air above the piston is permitted to readily escape from above while the overall resistance is determined by operation of a lower relief valve. When the microphone is placed back in the receptacle, the weight of the piston pulls the cable back within the housing, with air venting structure providing an air damping feature to slow the retraction of the cable.Type: ApplicationFiled: March 15, 2013Publication date: September 19, 2013Applicant: XEDIT CORPORATIONInventor: Claude M. Karczmer

Patent number: 8520879Abstract: Provided is an integrated gooseneck condenser microphone including a microphone unit and an output module which are connected to each other. The gooseneck condenser microphone can improve the connection strength of a microphone housing and prevent the generation of noise due to disturbance electromagnetic waves. The gooseneck condenser microphone includes a connection member 20b which is provided at the rear end of a shielded housing 20a and into which the leading end of a supporting pipe 30 is inserted and an electrical insulating member 6 that is interposed between the connection member and the supporting pipe and electrically insulates the connection member from the supporting pipe. A groove portion 5 is formed in the inner circumferential surface of the connection member along the circumferential direction, and the leading ends of the supporting pipe and the electrical insulating member inserted into the connection member are fitted to the groove portion while the diameters thereof are expanded.Type: GrantFiled: April 12, 2012Date of Patent: August 27, 2013Assignee: Kabushiki Kaisha Audio-TechnicaInventor: Satoshi Yoshino

Patent number: 8520880Abstract: A boundary microphone is provided to effectively reduce noises caused by external electromagnetic waves by providing electrostatic shielding, including on the portion of lead wires from a microphone unit to a circuit board. The boundary microphone has a base plate, a cover, a circuit board, and a microphone unit mounted in the opening with a metallic holder. A shield pattern for electrostatically shielding inside of the recess with the base plate is formed on the circuit board. The holder is configured to include a cylindrical section into which a rear end side of the microphone unit is fitted, and a D-cut section in which a part of a circumferential surface and a base surface of a cylinder with a base integral with the cylindrical section are cut away in parallel to a board surface of the circuit board, and the lead wire is routed within the D-cut section.Type: GrantFiled: September 30, 2011Date of Patent: August 27, 2013Assignee: Kabushiki Kaisha Audio-TechnicaInventor: Hiroshi Akino

Patent number: 8509469Abstract: An implantable microphone is disclosed having an external diaphragm and housing that forming chamber capable of being pressurized by deformational movement of the diaphragm induced by pressure waves (e.g., acoustic signals) propagating through overlying tissue. The chamber is shaped such that the volume of the chamber upon deflection of the diaphragm is reduced compared to a static volume of the chamber (i.e., volume of the chamber with no diaphragm deflection). As a result, the change in pressure within the chamber for a given diaphragm displacement is greater than it would be within a chamber having a cylindrical volume, leading to greater microphone sensitivity. In one arrangement, the chamber is shaped such that it is deeper at its center than at its edges, for example, to form a conical or paraboloidal volume.Type: GrantFiled: February 18, 2011Date of Patent: August 13, 2013Assignee: Cochlear LimitedInventors: Scott Allan Miller, III, Robert Edwin Schneider

Patent number: 8498425Abstract: A headset includes a wearable body, first and second earphones extending from the wearable body, controls for controlling an external communication/multimedia device wirelessly, a microphone for picking up vocal data from a user of the headset system and a signal processing unit. The signal processing unit includes circuitry for processing the vocal data into a distinctly audible vocal feedback signal, circuitry for enhancing the vocal feedback signal thereby producing an enhanced vocal feedback signal and circuitry for mixing the enhanced vocal feedback signal with audio signals originating from the external communication/multimedia device, thereby producing a mixed output signal and then sending the mixed output signal to the user via the earphones. The external communication/multimedia device comprises a vocal command application and the headset further comprises a vocal command control for sending vocal commands to the external communication/multimedia device and to the vocal command application.Type: GrantFiled: August 11, 2009Date of Patent: July 30, 2013Assignee: Onvocal IncInventor: Will Wang Graylin
