Output signals from the microphone devices can be combined (e.g., by weighted or unweighted summation or differencing) to form sub-element output signals and/or element output signals, and ultimately a single array output signal for the microphone array. The PCB may be uniformly flexible or may have rigid sections interconnected by flexible portions. Possible 3D shapes include (without limitation) cylinders, spirals, serpentines, and polyhedrons, each formed from a single flexible PCB. Alternatively, the microphone array may be an assembly of multiple, interconnecting sub-arrays, each having two or more rigid portions separated by one or more flexible portions, where each sub-array has at least one cut-out portion for receiving a rigid portion of another sub-array. | 2012-11-01 |
20120275622 | Electronically compensated micro-speakers - Electronics for altering the audio frequency response of a micro-speaker without modifying the micro-speaker itself are used to provide a selected frequency response of the micro-speaker. The micro-speaker has a resonant peak region, from which the response declines for both higher and lower frequencies. In one embodiment the electronics includes a first circuit for modifying the frequency response curve up to the resonant peak region, and a second circuit for modifying the frequency response curve for audio frequencies higher than this region. Each filter yields an integer multiple of 6 dB per octave slope. In the described embodiment, for approximately correcting presbyacusis (age related hearing loss), a set of high pass filters, low pass filters, and/or high order filters are connected to the micro-speaker to progressively attenuate the frequency response curve as the frequency decreases from 10000 Hz to 100 Hz. | 2012-11-01 |
20120275623 | MOBILE WIRELESS COMMUNICATIONS DEVICE HAVING IMPROVED RF IMMUNITY OF AUDIO TRANSDUCERS TO ELECTROMAGNETIC INTERFERENCE (EMI) - A mobile wireless communications device includes a housing and circuit board carried by the housing and having radio frequency (RF) circuitry and a processor operative with each other. Audio circuitry is carried by the circuit board and an audio transducer assembly, such as a speaker, has electrical contacts that electrically engage the audio circuitry for carrying audio signals between the audio circuitry and audio transducer assembly. A filter is mounted at the audio transducer assembly and reduces radio frequency (RF) electromagnetic interference to the audio transducer assembly during device operation. | 2012-11-01 |
20120275624 | ENERGY-SAVING AUDIO-AMPLIFIER CONTROL DEVICE - An energy-saving audio-amplifier control device is electrically connected to an amplifier for sensing an audio signal input state at a sound-source input end of the amplifier and controlling the on/off of the amplifier accordingly. The control device includes a signal detection module, a control module and a power control module. The signal detection module detects the state at the sound-source input end and generates a first signal to the control module. Based on the first signal, the control module controls the power control module to control the on/off of the amplifier. With these arrangements, it is able to automatically control the amplifier to off when the audio signal input to the amplifier is ended, and accordingly, achieve the purpose of saving energy, reducing power consumption, and minimizing loss of components. | 2012-11-01 |

20120275626 | DIGITAL AUDIO MIXER AND METHOD THEREOF - In a digital audio mixer and a method thereof, three effecter group lists corresponding to effecter group switches can be stored in a current memory. The first effecter group list can include member data identifying a plurality of effecters that constitute an effecter group. Each of the member data can include an effecter ID (eID) identifying an effecter (internal effecter, external effecter or default effecter) inserted in a desired insertion point of a desired channel. In response to operation of any one of the effecter group switches, a CPU can collectively set ON/OFF states of all of the effecters of the effecter group to a same state on the basis of the first effecter group list. | 2012-11-01 |
