  • Patent number: 10271150
    Abstract: Examples described herein involve calibration of a microphone. In an example implementation, while a network device is positioned within a predetermined physical range of a microphone of a playback device, the network device detects, via a microphone of, a first audio signal. The network device also receives data indicating a second audio signal detected by the microphone of the playback device. Based on (i) data indicating the first audio signal, (ii) the data indicating the second audio signal, and (iii) an acoustic characteristic of the microphone of the playback device, the network device determines an acoustic characteristic of the microphone of the network device and generates a microphone calibration algorithm based on the determined acoustic characteristic of the microphone of the network device. The network device then applies the microphone calibration algorithm when performing an acoustic calibration of the playback device.

  • Patent number: 9936318
    Abstract: Examples described herein involve calibration of a playback device. In an example, a system maintains a database of representative acoustic characteristics. Each representative acoustic characteristic corresponds to a respective plurality of network devices and the network devices in each respective plurality of network devices shares characteristics. The system receives, from a particular network device, data indicating characteristics of the particular network device, an identification of a playback device, and data indicating audio detected by the particular network device while the playback device played a calibration tone. The system identifies, in the database, the representative acoustic characteristic corresponding to those characteristics. Based on the identified representative acoustic characteristic, the identification of the playback device, and the data indicating the detected audio, the system determines an audio processing algorithm to adjust audio output of the playback device.

  • Patent number: 8871321
    Abstract: A method of fabricating an ornamental purfling strip which has sufficient flexibility to be placed within a curved configuration. The ornamental purfling strips are sufficiently flexible to be placed, as a single unit, in curved channels which require the strip to bend. The flexibility results from a laminated structure comprising a layer of binding material overlain by an ornamental layer, with an adhesive or bonding agent attaching the layers together. The ornamental layer comprises a plurality of precisely placed breaks along its length. The binding material retains the individual fragments of the ornamental layer in the strip, but because the binding material comprises a flexible material, the layer of binding material is sufficiently flexible to allow the purfling strip to flex longitudinally and transversely. The ornamental layer may comprise organic shell material or synthetic materials such as synthetic opal.

    Abstract: A musical instrument is provided. When the lid is revolved in a direction to open the lid from a close state of the lid, the guided part is guided to an inner peripheral concave surface of the guiding channel and is engaged with the inner peripheral concave surface. The lid is supported by the bearing bar 30, and the lid is maintained being up. After the lid is revolved in a direction to further open the lid from the open state and the guided part is disengaged from the inner peripheral concave surface, the lid can be laid down by revolving in a direction for laying down the lid. Therefore, the lid can be changed to an open state or a close state by only revolving the lid.

  • Patent number: 8017858
    Abstract: An instrument in which an acoustic or otherwise measurable disturbance or change is made in physical matter is disclosed. In one embodiment an oscillatory vortex shedding phenomenon is formed in water, in association with each of a plurality of finger holes. Water flows past a branch point where it can either flow over a labium, edge or the like in a resonant pipe, or out a finger hole, the finger hole being the path of lesser resistance to the water. Obstruction of the finger hole forces the water past an underwater sound production mechanism. Blocking water from coming out of a given hole produces a given note, which, in some embodiments, is electrically amplified by a hydrophone. In one embodiment there is a further processing of each hydrophone signal. Embodiments with various kinds of acoustic or optical pickups are also disclosed.

    Abstract: Methods and apparatus are provided that help users learn to play one or more instruments by employing simplified note recognition techniques, improved feedback, and a simplified keyboard tablature. In one aspect, users are encouraged to play specified notes within a specified time frame. The pitch and duration can be represented in any suitable manner, but are advantageously displayed together as a single icon (232A-232F). Preferably, the icon has an elongated shape in which the horizontal length correlates with duration of the note, and its vertical position on a display correlates with a pitch of the note. Notes can thus be represented by elongated lines, bars, ellipses, or even missiles or arrows. In another aspect, an improved musical tablature effectively clusters juxtaposed black keys (412A, 412C, 412E) and white keys (412B, 412D) on a display for easier visualization.

    Abstract: This invention provides a system for customizing musical instrument signal processing enabling users to produce different tonal characteristics in created musical pieces. In order to create such tonal characteristics, a new mathematical model of tonal characteristics may be digitally created based on two or more initial mathematical models of tonal characteristics. After simulating a first and second initial mathematical models of tonal characteristics, the new mathematical model is created by interpolating one or more coefficients of the first and second initial mathematical models. The new mathematical model may also adjust a control parameter where the control parameter may exist between two values. When the control parameter is the first value, the new mathematical model is the first initial mathematical model. When the control parameter is the second value, the new mathematical model may be the second initial mathematical model.
