摘要： The present invention discloses a method and an apparatus for earphone sound effect compensation and an earphone. The method of the present invention comprises: obtaining monitored signal data in a current wearing state of an earphone user according to a signal collected by a monitoring microphone and an audio signal played by a loudspeaker of the earphone; computing error data of the monitored signal data in the current wearing state relative to standard signal data in a standard wearing state of the earphone; and performing sound effect compensation to the earphone according to the error data. The technical solution of the present invention adopts an adaptive digital signal processing manner, which can dynamically compensate for sound effects in different earphone wearing manners and enable an earphone user to appreciate an audible effect in a standard earphone wearing state.

摘要： An example headphone arrangement includes at least one earphone. The at least one earphone includes a sealed housing having an aperture and a tube with a longitudinal axis. The tube is curved along its longitudinal axis to form a closed or open ring configured to totally or partly surround an ear of a user. A speaker is mounted to the housing at the aperture so that the housing in connection with the speaker encloses a closed acoustic volume.

摘要： A headphone assembly is described having a concha-style headphone including an earpiece at least partially covered in dual foam and a headband for providing a clamping force sufficient to the seal the concha of a user's with the earpiece. The earpiece may be shaped to fit different concha sizes and shapes to provide a universal fit. The dual foam may include a layer of memory foam underneath acoustically-transparent, porous outer foam. The earpiece may further include a transducer and at least one microphone positioned with the earpiece to receive sound radiated by the transducer and noise. The headphone assembly may be equipped with an active noise-canceling (ANC) control system configured to receive an audio input signal from an audio source and provide a filtered audio output signal to the transducer based on part on a perceived frequency response of the headphone as measured by the microphone.

摘要： An integrated circuit may include an output for providing a signal to a transducer including both source audio for playback to a listener and an anti-noise signal for countering the effects of ambient audio sounds in an acoustic output of the transducer, a microphone input for receiving a microphone signal indicative of ambient sounds at the transducer, a link control input for receiving link control information of a communications link coupling the integrated circuit to the transducer and/or a microphone for generating the microphone signal, wherein the link control information includes a link quality metric of the communications link, and a processing circuit comprising a filter having a response that generates the anti-noise signal in conformity with the microphone signal to minimize the ambient sounds at the acoustic output of the transducer, wherein the processing circuit modifies generation of the anti-noise signal responsive to the link quality metric.

摘要： An electronic hearing protector includes an ear cup assembly comprising a front exterior microphone that provides a front microphone signal and a rear exterior microphone that provides a rear microphone signal. A processor receives and digitizes the front microphone signal and the rear microphone signal, and provides a front channel signal and a rear channel signal indicative thereof respectively. A filter receives the rear channel signal and has a cut-off frequency value that provides a high-frequency roll-off and a notch at a notch filter frequency value that is less than the cut-off frequency value, where the filter provides a filtered signal. A first signal indicative of the front channel signal and a second signal indicative of the filtered signal are summed, and a signal indicative of the summed signal is provided to a speaker within the ear cup that provides an audio signal within the first ear cup indicative of the summed signal.

摘要： A loudspeaker arrangement comprises a first loudspeaker configured to radiate an acoustical signal, and a first microphone that is acoustically coupled to the first loudspeaker via a secondary path and that is electrically coupled to the first loudspeaker via an active noise control processing unit. During the use of the loudspeaker arrangement, the first loudspeaker is arranged at a first distance from a first active noise control target position, wherein the first active noise control target position is a position at which noise is to be suppressed, and wherein the first distance is a length of the shortest path between the first loudspeaker and the first active noise control target position through free air. The first microphone is arranged at a second distance from the first loudspeaker, wherein the second distance is a length of the shortest path between the first loudspeaker and the first microphone through free air. The first distance equals the second distance, and the position of the first microphone differs from the first active noise target position.

摘要： The disclosure relates to a microphone arrangement comprising at least three groups of microphones that are mounted on a head-wearable support structure. The at least three groups of microphones comprising a first group of microphones with one or more microphones, a second group of microphones with one or more microphones, and a third group of microphones with one or more microphones, wherein the first group is mounted to a casing that accommodates signal transmission circuitry, the second group is mounted to slide with respect to the casing and the first group is mounted in a direction of a first axis. Furthermore, the third group comprises either at least one microphone that is arranged on the support structure so as to exhibit less sensitivity for sound coming from a user's mouth than for sound coming from a user's environment when the microphone arrangement is head-worn; or at least two microphones that are arranged symmetrically with respect to a user's head when the microphone arrangement is head-worn and that provide for a directionality that is orientated to the direction of a user's vision; or both.

摘要： An in-ear headphone comprises an earbud body constructed and arranged for positioning in an ear canal of a wearer, and configured to have a distal end farther into the ear canal than a proximal end. The earbud body includes a cavity and an opening to the cavity. The in-ear headphone further comprises a transducer in the opening to the cavity, a portion of the transducer facing outward from the opening; a microphone at the distal end of the earbud body; an earbud tip on the earbud body and complying with a surface of the earbud body; and an acoustically resistive mesh structure at a distal end of the earbud tip. The mesh structure covers the microphone and the portion of the transducer facing outward from the opening.
