Abstract
A wearable sound device includes a venting module, configured to form at least one vent to connect a volume within the wearable sound device and ambient, and a sound producing device, configured to produce sound according to an equalized input signal. The venting module, including at least one venting device, operates among a plurality of statuses corresponding to a plurality of degrees of opening. A controller generates the equalized input signal according to a degree of opening among the plurality of degrees of opening, in order to counteract a roll off caused by the at least one vent.
Claims28
A wearable sound device, comprising:
- a venting module, comprising at least one venting device, configured to form at least one vent to connect a volume within the wearable sound device and ambient;
- and
- a sound producing device, configured to produce sound according to an equalized input signal;
- wherein the venting module operates among a plurality of statuses corresponding to a plurality of degrees of opening;
- wherein a controller generates the equalized input signal according to a degree of opening among the plurality of degrees of opening, in order to counteract a roll off caused by the at least one vent.
A device, comprising:
- a controller, configured to generate an equalized input signal according to a degree of opening among a plurality of degrees of opening of a venting module;
- wherein the venting module is configured to form at least one vent and has the plurality of degrees of opening;
- wherein the controller generating the equalized input signal is to counteract a roll off due to the at least one vent.
An equalizing method, configured to generate an equalized input signal for a sound producing device, the equalizing method comprising:
- obtaining a status of a venting module among a plurality of statuses, wherein the venting module forming at least one vent operates among the plurality of statuses corresponding to a plurality of degrees of opening;
- and
- generating the equalized input signal according to the status.
A wearable sound device, comprising:
- an acoustic transducer, configured to form at least one opening to connect a volume within the wearable sound device and ambient and configured to produce sound according to an equalized input signal;
- wherein the acoustic transducer operates among a plurality of statuses corresponding to a plurality of degrees of opening;
- wherein a controller generates the equalized input signal according to a degree of opening among the plurality of degrees of opening, in order to counteract a roll off caused by at least one vent.
