摘要： The loudspeaker assembly comprises at least first, second and third loudspeakers L1-L4 configured to produce sound along respective at least first second and third mutually angularly-offset principal radiating axes X1-X4. A control unit is configured to filter at least two of the first, second and third electrical signals which drive the respective loudspeakers so that there is a first gain and phase difference between the first and second electrical signals and a second gain and phase difference between the first and third electrical signals. The first and second angular offsets and the first and second gain and phase differences are configured so that, when the loudspeaker assembly is in use, direct sound produced by multiple loudspeakers in the loudspeaker assembly is cancelled in accordance with a predetermined cancelling condition at each of a first listening position and a second listening position (fig 3).

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： A loudspeaker apparatus includes, for example, a first loudspeaker unit and a second loudspeaker unit that are configured to reproduce sound at least at a high frequency. The first loudspeaker unit and the second loudspeaker unit are placed on a plane having an axis extending in a horizontal direction and an axis extending in a vertical direction. The first loudspeaker unit is placed so as to be directed horizontally forward. The second loudspeaker unit is placed so as to be directed vertically upward to make an approximately 90° angle with the first loudspeaker unit. When a center of a diaphragm fixing face of the first loudspeaker unit is placed at an origin of the plane, and it is assumed that X represents a horizontally rearward direction and Y represents a vertically upward direction, the second loudspeaker unit is placed in a manner that coordinates of a center of a diaphragm fixing face of the second loudspeaker unit lie on a straight line represented by the following formula in the plane: Y = ˆ’ aX + b , where a > 0 , b > 0 , X > 0 , Y > 0.

摘要： An acoustic input module and an electronic device including the same are provided. The electronic device includes at least first and second transducers mounted on one surface of a circuit board, a control module mounted on the circuit board for controlling the transducers, and a plurality of sound input holes formed in a housing of the electronic device. The first transducer receives a sound along a first directional path through a first sound input hole and converts the received sound into an electrical signal, and the second transducer receives a sound along a second directional path through a second sound input hole and converts the received sound into an electrical signal. Since the transducers detect sounds originating along different paths, the electronic device can include a multi-channel recording function with an ability to reinforce sound of a specific object and attenuate other sound.

摘要： A multi-channel headphone has a housing (10), multiple independent sound channels (12, 13) formed in the housing (10), and at least one speaker unit (20) mounted inside the housing (10). The at least one speaker unit (20) produces sound directly passing through one of the sound channels (13) and refracted through the rest of sound channels (12). As the refracted sound is slower than the directly travelling sound, multiple layers of auditory feeling can be provided and a stereo sound effect can be generated for users to enjoy better auditory feeling.
