Abstract
The technology described in this document can be embodied in an apparatus that includes an open headphone, a subwoofer, and a controller. The open headphone includes an electroacoustic transducer, and a support structure for supporting the electroacoustic transducer proximate to a user's ear in an acoustically open configuration. The subwoofer is configured to output low-frequency audio, and the controller includes one or more processing devices. The controller is configured to generate one or more control signals to control the audio output from one or both of the electroacoustic transducer and the subwoofer, and control one or both of the electroacoustic transducer and the subwoofer using the generated control signals.
Claims18
An apparatus comprising:
- an open headphone comprising:
- an electroacoustic transducer, and
- a support structure for supporting the electroacoustic transducer proximate to
- a user's ear in an acoustically open configuration;
- a subwoofer configured to output low-frequency audio;
- and
- a controller comprising one or more processing devices, the controller configured to:
- determine a target frequency response of the apparatus;
- determine, in accordance with the target frequency response, a cross-over frequency for distributing audio output between the electroacoustic transducer and the subwoofer to balance acoustic output of the open headphone and the subwoofer, wherein the cross-over frequency is determined such that the low-frequency audio output of the subwoofer is unlocalizable;
- generate one or more control signals to control the audio output from one or both of the electroacoustic transducer and the subwoofer, wherein the one or more control signals are generated in accordance with the target frequency response of the apparatus and the cross-over frequency;
- and
- control one or both of the electroacoustic transducer and the subwoofer using the generated control signals.

An apparatus comprising:
- an open headphone comprising:
- an electroacoustic transducer, and
- a support structure for supporting the electroacoustic transducer in an acoustically open configuration;
- and
- a controller comprising one or more processing devices, the controller configured to:
- establish a connection with a subwoofer configured to output low-frequency audio,
- determine, a target frequency response of the apparatus;
- determine, in accordance with the target frequency response of the apparatus, a cross-over frequency for distributing audio output between the electroacoustic transducer and the subwoofer to balance acoustic output of the electroacoustic transducer and the subwoofer, wherein the cross-over frequency is determined such that the low-frequency audio output of the subwoofer is unlocalizable;
- generate one or more control signals for controlling the audio output from one or both of the electroacoustic transducer and the subwoofer, wherein the one or more control signals are generated in accordance with the target frequency response of the apparatus and the cross-over frequency, and
- provide the one or more control signals for controlling one or both of the electroacoustic transducer and the subwoofer.
11-12. (canceled)
A method comprising:
- establishing, by a controller that includes one or more processing devices, a first connection to an open headphone that includes an electroacoustic transducer;
- establishing, by the controller, a second connection with a subwoofer configured to output low-frequency audio;
- determining a target frequency response of the electroacoustic transducer and the subwoofer;
- determining, by the controller in accordance with the target frequency response, a cross-over frequency for distributing audio output between the electroacoustic transducer and the subwoofer to balance the acoustic output of the electroacoustic transducer and the subwoofer, wherein the cross-over frequency is determined such that the low-frequency audio output of the subwoofer is unlocalizable;
- generating one or more control signals for controlling the audio output from one or both of the electroacoustic transducer and the subwoofer in accordance with a target frequency response and the adjusted cross-over frequency;
- and
- providing the one or more control signals for controlling one or both of the electroacoustic transducer and the subwoofer.
