  • Patent number: 10911853
    Abstract: An musical instrument amplifier-mounted microphone assembly operatively attaches to the seal of an instrument speaker to capture sound waves, without losing unique sounds. The microphone assembly utilizes electret condenser microphones to achieve boundary layer configuration. The microphone assembly fits flush against, or parallel to, the speaker baffle that holds the microphone assembly in front of speaker cones. The microphone assembly mounts on a circuit board which acts as a reflective surface to achieve boundary layer effect. The flat circuit board provides flat conductor traces that carry audio signals from the electret assembly, past the gasket seal of the speaker, to electronics on the board that power, amplify and match impedances needed to pass the audio signal to a large venue amplification system. A connector terminal on the circuit board connects via a shielded cable to a housing mounted XLR connector that provides connection to a large venue amplification system.

  • Patent number: 10904679
    Abstract: A method for enhancing a signal directionality in a hearing instrument wherein first and second signals are generated by first and second input transducers that are spaced apart from one another. A first directional signal is derived from the first input signal and the second input signal by applying a second-to-first relative transfer function with respect to a first target angle to the second input signal. The second-to-first relative transfer function is a relative transfer function from the second input transducer to the first input transducer with respect to the first target angle. Similarly, a second directional signal is derived from the second input signal and the first input signal by applying a first-to-second relative transfer function with respect to a second target angle to the first input signal. An angle-enhanced signal is derived from the first directional signal and the second directional signal.

The system includes first and second audio detectors associated with first and second ears of a user, respectively. The audio detectors detect an audio signal presented to the user and generate the first and second signals to represent the audio signal as detected at the first and second ears, respectively. The system also includes a first sound processor that receives the first signal from the first audio detector and the second signal from a second sound processor via a communication link with the second sound processor. The first sound processor generates a directional signal representative of a spatial filtering of the audio signal detected at the first ear according to an end-fire directional polar pattern and presents an output signal representative of the directional signal to the user at the first ear.

  • Patent number: 10448135
    Abstract: A case for a portable electronic device includes an enclosed, elongated space extending within the case from an opening in an interior surface of the case. The opening corresponds to the location of a microphone in the device. The enclosed space is tapered to an increasingly smaller cross-section as it extends away from the opening. A first edge of the enclosed space aligns along most of its length with an exterior surface of the case. A screen covers a second opening in the exterior surface of the case along the first edge of the elongated space and provides an acoustic resistance between the elongated space and air outside the case through the second opening. A gasket located at the first opening couples the elongated space to the microphone of the electronic device.

  • Patent number: 10440461
    Abstract: Systems, apparatuses and methods may provide for an earpiece that includes an audio subsystem and a longitudinal housing that is bendable between a substantially straight shape and a substantially curved shape. The longitudinal housing may contain the audio subsystem and include a flexible material. Additionally, a speaker may be coupled to the audio subsystem and positioned at an end of the longitudinal housing. In one example, the earpiece also includes a controller coupled to the flexible material, wherein the controller generates one or more control signals that cause the flexible material to automatically complete a bend of the longitudinal housing to the substantially curved shape.

  • Patent number: 10397711
    Abstract: The present disclosure relates in a first aspect to a method of determining an objective perceptual quantity of a noisy speech signal using directional sound information. The method comprises steps of applying a noisy speech signal comprising a mixture of target speech and interfering noise to a first hearing instrument with an adjustable microphone arrangement and controlling the adjustable microphone arrangement to produce first and second directivity patterns exhibiting first and second directivity indexes, respectively, wherein said second directivity index is smaller than the first directivity index at one or more reference frequencies. First and second noisy speech segments are recorded from the adjustable microphone arrangement using the first and second directivity patterns, respectively, and at least one value of the objective perceptual quantity of the noisy speech signal is determined by comparing the first noisy speech segment and the second noisy speech segment.

  • Patent number: 10277973
    Abstract: Ear buds may have sensors to gather orientation information such as accelerometer measurements during user movements. A host electronic device may communicate wirelessly with the ear buds and may form part of an ear bud system that supplies the user with coaching and feedback while evaluating user performance of a head movement routine or other exercise routine. During operation, the ear buds may gather accelerometer data in a first reference frame such as a reference frame associated with the ear buds and may use a rotation matrix to rotate the data in the first reference frame into a second reference frame such as a neutral reference frame with a fixed orientation to the earth. The data in the neutral reference frame may be analyzed using a user head pose look-up table to categorize measured user head positions as corresponding to respective user head poses.
