A method for speech equalization, comprising the steps of receiving an input audio signal, processing said input audio signal in dependence on frequency and to providing an equalized electric audio signal according to an equalization function, wherein said equalization function comprises at least an actuator part configured to dynamically applying a compensation filter to the received input signal and dynamically applying a transparent filter to the received input signal, and further transmitting an output signal perceivable by a user as sound representative of said electric acoustic input signal or a processed version thereof.

Loudspeaker system provided with dynamic speech equalization

An earcup for a headphone, comprising at least one earcup comprising a front opening adapted to be adjacent to the ear of a user of the headphone, a baffle disposed within the earcup to define front and rear cavities, an outer cup arranged to accommodate the rear cavities, a first inner cup arranged within the rear cavity surrounding the front opening, a transducer and an earpad extending around the periphery of the front opening of the earcup arranged to accommodate the front cavity and the ear of the user, and wherein the earcup comprises a second inner cup arranged between the outer cup and the back-volume cup for providing an acoustic barrier between outside noise and the ear of the user.

Headphone sealing cup

A method is disclosed, the method comprising obtaining at least one first information indicative of audio data gathered by at least one first microphone, and at least one second information indicative of audio data gathered by at least one second microphone; determining a differential information indicative of one or more differences between at least two pieces of information, wherein the differential information is determined based, at least in part, on the at least one first information and the at least one second information; and compensating of an impact onto the audio data, wherein audio data of the first information and/or the second information is compensated based, at least in part, on the determined differential information. Further, an apparatus, and a system are disclosed.

Differential audio data compensation

A method for optimizing speech pickup in a speakerphone system, wherein the speakerphone system comprises a microphone system placed in a specific configuration, wherein the method comprising receiving acoustic input signals by the microphone system, processing said acoustic input signals by using an algorithm for focusing and steering a selected target sound signal towards a desired direction, and transmitting an output signal based on said processing.

Method for optimizing speech pickup in a communication device

A speaker device is disclosed. The speaker device includes a speaker enclosure structure including a speaker. The speaker is an electro-mechanical component, which in operation generates sound waves by deflection of a speaker membrane and in collaboration with the speaker enclosure structure. The speaker device further includes a speaker device housing. The speaker device housing is an outer shell of the speaker device and may accommodate additional electronic components required for operation of the speaker or for other purposes. The speaker enclosure structure is mechanically coupled to the speaker device housing. The speaker device further includes at least one coupling element, wherein the speaker enclosure structure is mechanically coupled to the speaker device housing by the at least one coupling element, the coupling element having a vibration damping structure configured to inhibit mechanical vibrations being transmitted through the coupling element.

System for reducing vibrations in loudspeaker
