Integrated processing of multimedia signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated multimedia system includes a main player that captures and processes signals digitally. The main player may adjust the audio signal to provide audio output of equal loudness across all frequencies by accounting for sensitivity of the human ear for sounds of varying frequencies. The main player can also account for perceived differences in loudness based on the angle of a listener to a speaker by detecting the position of a user and making an adjustment accordingly. The invention further provides a speaker that has embedded performance characteristics or an identifier that allows the system to provide an optimal speaker driving current for a particular system or determine how that speaker would be best implemented in the integrated system.

The present invention teaches a wireless ear-piece headset forming an antenna with the interior of a human ear, especially the ear canal. An antenna in operative connection with such interior of such human ear greatly improves reception and transmission of the device. The antenna may be comprised of a conductive plastic forming the lower body of the ear-piece headset, a sound tube projecting from the body or only a part thereof. The antenna may form an efficient capacitive connection with the body or may form a direct electrical connection. The wireless ear-piece headset comprises a headset body; a microphone, a transceiver, a receiver and a battery within the headset body, and a sound tube projecting from the headset body. A mini-speaker disposed within the headset body passes sound from the mini-speaker out and into the interior of a human ear.

Techniques have been developed for transmitting and receiving information conveyed through the air from one portable device to another as a generally unperceivable coding within an otherwise recognizable acoustic signal. For example, in some embodiments in accordance with the present invention(s), information is acoustically communicated from a first handheld device toward a second by encoding the information in a signal that, when converted into acoustic energy at an acoustic transducer of the first handheld device, is characterized in that the acoustic energy is discernable to a human ear yet the encoding of the information therein is generally not perceivable by the human. The acoustic energy is transmitted from the acoustic transducer of the first handheld device toward the second handheld device across an air gap that constitutes a substantially entirety of the distance between the devices. Acoustic energy received at the second handheld device may then be processed using signal processing techniques tailored to detection of the particular information encodings employed.

The invention discloses a voice enhancing method based on a multiresolution auditory cepstrum system and a deep convolutional neural network. The voice enhancing method comprises the following steps:firstly, establishing new characteristic parameters, namely multiresolution auditory cepstrum coefficient (MR-GFCC), capable of distinguishing voice from noise; secondly, establishing a self-adaptivemasking threshold on based on ideal soft masking (IRM) and ideal binary masking (IBM) according to noise variations; further training an established seven-layer neural network by using new extracted characteristic parameters and first/second derivatives thereof and the self-adaptive masking threshold as input and output of the deep convolutional neural network (DCNN); and finally enhancing noise-containing voice by using the self-adaptive masking threshold estimated by the DCNN. By adopting the method, the working mechanism of human ears is sufficiently utilized, voice characteristic parameters simulating a human ear auditory physiological model are disposed, and not only is a relatively great deal of voice information maintained, but also the extraction process is simple and feasible.

The invention relates to a robust ear detection method which improves an AdaBoost arithmetic and belongs to the technical field of image mode identifying. The invention is characterized by proposing an ear detection method with excellent performances under a complex underground. The invention proposes four anisomerous Haar-like corner characteristics which are used for describing the grayscale changes on the partial areas of the ears; a policy of subsection selection is adopted for selecting the best sorting threshold of the Haar-like characteristics, thus reducing the sample training time; the weight of a weak sorter is modified for reducing the mistaken detection rate of the sorter; the threshold HW is set and eliminated according to the distribution change of the sample weight in the training, thereby preventing an over-studying phenomenon from being generated and leading the miss-detection rate and the mistaken direction rate of the ear detection to be reduced; besides, the invention also provides a single-ear detection policy for leading both the defection efficiency and the detection effect to be improved. The excellent performances of the robust ear detection method are shown on a PC machine and a DSP.
