An audio transducer device includes an audio transducer, a controller and a direction adjusting mechanism. The audio transducer has a sound receiving surface formed with multiple sound collecting holes, and multiple microphones corresponding in position to the sound collecting holes. The controller is detachably mounted to an electronic device, and controls the microphones to cooperatively perform directional sound reception to obtain audio data. The direction adjusting mechanism interconnects an audio transducer shell and the controller such that the sound receiving surface can be rotated to a position where a normal direction thereof and an image capturing direction of the electronic device forming a desired angle therebetween.

[Problem] To provide a neck-worn device in which a battery or other electronic component is disposed at an appropriate location.

[Solution] This neck-worn device is to be worn at the neckline of a wearer, wherein a body part 30 comprises: a battery 90; a circuit board 85 on which is installed an electronic component that is driven by receiving power supplied from the battery 90; and a body part casing 32 in which the battery 90 and the circuit board 85 are stored. The circuit board 85 is disposed inside the body part casing 32 so as to be positioned in between the battery 90 and the neckline of the wearer while the device is being worn.

[Effect] Heat generated from the battery 90 is not readily transmitted to the wearer, thus improving the fit of the neck-worn device.

An eyewear device includes an audio system. In one embodiment, the audio system includes a microphone array that includes a plurality of acoustic sensors. Each acoustic sensor is configured to detect sounds within a local area surrounding the microphone array. For a plurality of the detected sounds, the audio system performs a direction of arrival (DoA) estimation. Based on parameters of the detected sound and/or the DoA estimation, the audio system may then generate or update one or more acoustic transfer functions unique to a user. The audio system may use the one or more acoustic transfer functions to generate audio content for the user.

Determination of a set of acoustic parameters for a headset is presented herein. The set of acoustic parameters can be determined based on a virtual model of physical locations stored at a mapping server. The virtual model describes a plurality of spaces and acoustic properties of those spaces, wherein the location in the virtual model corresponds to a physical location of the headset. A location in the virtual model for the headset is determined based on information describing at least a portion of the local area received from the headset. The set of acoustic parameters associated with the physical location of the headset is determined based in part on the determined location in the virtual model and any acoustic parameters associated with the determined location. The headset presents audio content using the set of acoustic parameters received from the mapping server.

A speaker unit that has a housing, a lower substrate that is fixed to the housing, a plurality of first ultrasonic vibrators that are arranged on the lower substrate, an upper substrate that is fixed to the housing and has a plurality of openings (OP) formed therein at locations that correspond to the first ultrasonic vibrators, and a plurality of second ultrasonic vibrators that are arranged on the upper substrate.

An insect repelling system utilizes a vehicle, and includes: a position information acquisition unit configured to acquire and provide vehicle position information, an interface unit configured to display species-based frequency ranges that insects avoid and to allow a user to select one of the displayed frequency ranges, a controller configured to perform control such that the interface unit displays the species-based frequency ranges that are avoided by insects that can be repelled at the current position of the vehicle based on the vehicle position information acquired by the position information acquisition unit and to generate and output a control signal for outputting a sound having the frequency selected through the interface unit, and a sound generation device configured to output the sound having the frequency by the user according to the control signal output by the controller.

Aspects of a multi-orientation playback device including at least one microphone array are discussed. A method may include determining an orientation of the playback device which includes at least one microphone array and determining at least one microphone training response for the playback device from a plurality of microphone training responses based on the orientation of the playback device. The at least one microphone array can detect a sound input, and the location information of a source of the sound input can be determined based on the at least one microphone training response and the detected sound input. Based on the location information of the source, the directional focus of the at least one microphone array can be adjusted, and the sound input can be captured based on the adjusted directional focus.

An audio processing method includes the following steps of capturing audio data by a microphone array to compute frequency array data of the audio data; computing a power sequence of degrees by using the frequency array data; and computing a difference value between a maximum value of the power sequence of degrees and a minimum value of the power sequence of degrees to determine whether the degree corresponding to the maximum value is a source degree relative to the microphone array.
