This disclosure relates generally to methods of generating tactile user feedback utilizing headphone devices, and systems including headphone devices configured to generate tactile user feedback. More specifically, disclosed embodiments relate to generating user feedback in ways that may be less intrusive than aural or visual feedback utilizing headphone devices configured to generate tactile user feedback.
Conventional portable audio systems often include a headphone that is connected to a media player (e.g., by one or more wires or by wireless technology). Conventional headphones may include one or more speaker assemblies having an audio driver that produces audible sound waves with a diaphragm. Such headphones may be connected to computing devices, such as, tablet devices, smartphones, video game consoles (e.g., portable video game consoles), and in-car infotainment systems. Such computing devices may provide user feedback, such as incoming text notifications or directions to follow a prescribed route, in the form of aural communications, which may be played over the headphones. Other devices connected to the computing devices, such as smart glasses and dash projectors, may provide user feedback in the form of visual communications displayed on such devices.
In some embodiments, the present disclosure includes methods of generating tactile user feedback utilizing a headphone device. In accordance with such methods, a feedback signal may be sent from a computing device to a headphone device operatively connected to the computing device. A tactile vibration may be generated utilizing a tactile bass vibrator of the headphone device in response to the feedback signal.
In additional embodiments, the present disclosure includes a system for generating tactile user feedback utilizing a headphone device. The system includes a headphone device operatively connected to a computing device. The headphone device has a tactile bass vibrator configured to generate a tactile vibration in response to a feedback signal received from the computing device, and the computing device is programmed to send a feedback signal to the headphone device in response to a predetermined event.
While this disclosure concludes with claims particularly pointing out and distinctly claiming specific embodiments, various features and advantages of embodiments within the scope of this disclosure may be more readily ascertained from the following description when read in conjunction with the accompanying drawings, in which:
The illustrations presented in this disclosure are not meant to be actual views of any particular apparatus or component thereof, but are merely idealized representations employed to describe illustrative embodiments. Thus, the drawings are not necessarily to scale.
Disclosed embodiments relate generally to generating user feedback in ways that may be less intrusive than aural or visual feedback by utilizing headphone devices configured to generate tactile user feedback. More specifically, disclosed are embodiments of headphone devices including tactile bass vibrators that may generate tactile user feedback in response to receiving a feedback signal from a connected computing device.
A “speaker” is defined herein as an acoustic device configured to contribute to the generation of sound waves, such as with the reproduction of speech, music, or other audible sound. A speaker may also produce tactile vibrations that may be felt by a person. Thus, a speaker may include a tactile bass vibrator. A tactile bass vibrator may also be referred to as a transducer, a driver, a shaker, etc.
A “bass frequency” is a relatively low audible frequency generally considered to be within the range extending from approximately 16 Hz to approximately 512 Hz. For purposes of this disclosure, a “low bass frequency” refers to bass frequencies that may be felt as well as heard. Such low bass frequencies may be within the range extending from approximately 16 Hz to approximately 200 Hz.
Referring to
The feedback signal may be sent from the computing device to the headphone device in response to various inputs. The inputs may be generated by the computing device itself, by another device connected to the computing device (e.g., a peripheral or accessory), or by user input to the computing device. The inputs may relate to activities about which the user may desire feedback. For example, the inputs may relate to health information (e.g., heart rate, distance traveled while exercising, pace maintained while exercising, etc.), navigation information (e.g., distance to destination, turning and lane directions, distance traveled, etc.), or other activities a user may engage in while using the headphone device and computing device (e.g., sports activities, leisure activities, work activities, etc.). A feedback signal relating to any such input may be sent from the computing device to the headphone device.
As one example, the feedback signal may be sent from the computing device to the headphone device in response to a signal from a heart rate monitor of the computing device or operatively connected to the computing device. More specifically, the feedback signal may be sent from the computing device to the headphone device in response to a signal from a heart rate monitor indicating that a user's heart rate has exceeded a predetermined threshold or is within a predetermined range.
As another example, the feedback signal may be sent from the computing device to the headphone device in response to location information gathered by the computing device (e.g., utilizing a global positioning system (GPS) of the computing device). More specifically, the feedback signal may be sent from the computing device to the headphone device in response to traveling a predetermined distance, travelling at a calculated rate over a predetermined distance interval, or approaching a change of course in a predetermined route. In some embodiments, the feedback signal may be sent to a particular channel or a particular tactile bass vibrator of the headphone device. For example, the feedback signal may be sent to a left-side tactile bass vibrator or a right-side tactile bass vibrator of the headphone device corresponding to a direction in which a user is to turn to follow navigation directions.
As yet another example, the feedback signal may be sent from the computing device to the headphone device in response to a signal from an altimeter that a predetermined altitude threshold has been crossed. More specifically, the feedback signal may be sent from the computing device to the headphone device in response to descending past a threshold altitude beyond which deployment of a parachute is recommended.
As still another example, the feedback signal may be sent from the computing device to the headphone device in response to a user input received at the computing device. More specifically, the feedback signal may be sent from the computing device to the headphone device in response to user interaction with one or more user interface devices (e.g., buttons, switches, touchscreens, etc.) of the computing device.
Such feedback signals may convey useful information for, for example, exercise tracking, navigation, adventure sports, operation of the computing device, and other activities users may engage in while using the computing device and the headphone device. While certain illustrative examples have been given of inputs for sending feedback signals, those examples are not limiting. Feedback signals may be sent from the computing device to the headphone device in response to any input received, or generated, by the computing device.
In some embodiments, another audio signal may be sent from the computing device to the headphone device. The other audio signal may be distinct from the feedback signal. For example, the other audio signal may not be configured to provide user feedback. More specifically, the other audio signal may be, for example, media audio (e.g., music, radio, or movie audio) or conversational audio (e.g., a telephone call) unconnected with the feedback audio. The other audio signal may be sent concurrently with the feedback signal. In other words, the headphone device may be actively emitting audible sound, such as during conventional use of a headphone for purposes of listening to music, voice, or other audible sounds, and, at the same time, the headphone may be used to provide haptic feedback to the user by actuating one or more one or more tactile bass vibrators of the headphone responsive to receipt of the feedback signal by the one or more tactile base vibrators from the computing device.
The method 100 may further involve generating a tactile vibration utilizing the tactile bass vibrator of the headphone device in response to the feedback signal, as indicated at action 104. The tactile vibration may be of an amplitude such that vibrations generated by the tactile bass vibrator are felt by a user wearing the headphone device, giving the user feedback associated with the tactile vibration. In addition, the tactile bass vibrator may produce some audible sound in addition to the tactile vibration. For example, the tactile bass vibrator may produce audible sound at bass frequencies. More specifically, the tactile bass vibrator may produce audible sound at low bass frequencies. The primary mechanism for giving the user feedback may be tactile. The audible sound generated in connection with the tactile vibration may be incidental to the vibratory sensation that is the primary means of sending feedback to the user.
The tactile vibration may be generated by the tactile bass vibrator of the headphone device in, for example, a predetermined vibration pattern. More specifically, the tactile vibration generated by the tactile bass vibrator of the headphone device may be, for example, a burst of vibratory tactile feedback at a predetermined frequency (e.g., a bass frequency or a low bass frequency) or a series of bursts of vibratory tactile feedback. As a specific, nonlimiting example, the tactile vibration generated by the tactile bass vibrator of the headphone device may be a predetermined series of bursts of vibratory tactile feedback separated by a predetermined series of rests between bursts, during which no vibratory tactile feedback associated with the feedback signal is generated.
In some embodiments, the predetermined vibration pattern of the tactile vibration generated by the tactile bass vibrator of the headphone device may be customizable by the user. For example, the predetermined vibration pattern for a particular notification to be sent to the user may be selected from a set of predetermined vibration patterns (and associated feedback signals) stored in memory of the computing device. More specifically, the predetermined vibration pattern for a particular notification to be sent to the user may be selected from a set of audio files composed of bass frequency waves stored in memory of the computing device. As a specific, nonlimiting example, the predetermined vibration pattern for a particular notification to be sent to the user may be selected from a set of audio files composed of low bass frequency waves stored in memory of the computing device. As another example of customizable vibration patterns, the predetermined vibration pattern may be defined by a user in response to user input at the computing device. More specifically, user interaction with a user input device (e.g., a button, switch, touchscreen, etc.) of the computing device may define the amplitude, frequency, duration, or any combination of amplitude, frequency, and duration of bursts of vibratory tactile feedback as well as the duration of rests between bursts, during which no vibratory tactile feedback associated with the feedback signal is generated.
As previously mentioned, audible sound may be generated by speakers (e.g., audio drivers) of the headphone device concurrently as tactile vibration is generated by the tactile bass vibrators. For example, audible sound corresponding to an audio signal may be generated by the speakers, and optionally by the tactile bass vibrators, while tactile vibrations corresponding to a feedback signal may be generated by the tactile bass vibrators alone. More specifically, the speakers, and optionally the tactile bass vibrators, may play, for example, media audio or telephone call audio at the same time as the tactile bass vibrators generate tactile vibrations.
Because the feedback given to the user by the tactile bass vibrators is felt, and optionally heard, as opposed to solely being heard, solely being seen, or being heard and seen, the feedback may be less intrusive than conventional feedback from computing devices. Moreover, the tactile feedback given to the user may not interrupt the experience of the user using the computing device (e.g., may not interrupt the audio played by the speakers, and optionally by the tactile bass vibrators) because its primary communication mechanism may be tactile, rather than aural or visual.
As one example of generating tactile feedback for a user while using the headphone device and computing device, a user may wear the headphone device connected to a computing device (e.g., a smartphone or fitness band wirelessly connected to a smartphone) while engaging in physical exercise (e.g., running, cycling, hiking, etc.). The fitness band may include a heart rate monitor, and information from the heart rate monitor may be sent from the fitness band to the smartphone for storage and processing. The smartphone may include a GPS unit and other wireless signal transceivers for generation and processing of location data.
The user may listen to one or more audio files (e.g., music, audiobooks, or radio programming, such as podcasts) while engaging in the physical exercise. The headphone device may produce audible sound and tactile vibrations in response to receiving the audio signals associated with the audio files.
When an event relating to the physical exercise has occurred, such as, for example, a user's heart rate entering a desired range or the user traveling a predetermined distance, a feedback signal may be sent from the computing device to the headphone device. The feedback signal may cause the headphone device to generate tactile vibrations distinct from the tactile vibrations generated in response to the audio signal, such as, for example, a series of short bursts of vibration. Depending on the specific pattern of the tactile vibrations and the predetermined semantic meaning assigned to the specific pattern of the tactile vibrations, the user may understand that his or her heart rate has entered a desired range, he or she has traveled a predetermined distance (e.g., a notification for each mile traveled), or that he or she has maintained a predetermined pace over the predetermined distance. As specific, nonlimiting examples, the headphone device may produce two short bursts of vibration, followed by a brief pause, followed by two additional short bursts of vibration (e.g., mimicking a heartbeat) to indicate that the user's heart rate has entered a desired range; may produce a single, sustained burst of vibration followed by a pause for each mile traveled since the physical exercise began; and may produce a single, sustained burst of vibration followed by a pause for each mile traveled since the physical exercise began followed by a short burst of vibration for each minute passed during the most recent mile, each of which may occur while the headphone device simultaneously generates the audible sound and tactile vibrations in response to the audio signal.
As another example of generating tactile feedback for a user while using the headphone device and computing device, a user may wear the headphone device connected to a computing device (e.g., a smartphone or in-car infotainment system) while navigating (e.g., while walking, cycling, or driving) to a desired destination. The smartphone or in-car infotainment system may include a GPS unit and other wireless signal transceivers for generation and processing of location data.
The user may listen to one or more audio files (e.g., music, audiobooks, or radio programming, such as podcasts) while navigating. The headphone device may produce audible sound and tactile vibrations in response to receiving the audio signals associated with the audio files.
When an event relating to the navigation has occurred, such as, for example, a user approaching a required deviation from the path (e.g., a turn or lane change) to continue toward the destination or a user reaching the destination, a feedback signal may be sent from the computing device to the headphone device. The feedback signal may cause the headphone device to generate tactile vibrations distinct from the tactile vibrations generated in response to the audio signal, such as, for example, a series of short bursts of vibration. Depending on the specific pattern of the tactile vibrations and the predetermined semantic meaning assigned to the specific pattern of the tactile vibrations, the user may understand that he or she should turn right or left at the next intersection, he or she should merge right or left before the next highway lane event (e.g., interchange, exit, entrance, etc.), or he or she should stop at the destination. As specific, nonlimiting examples, the headphone device may produce two short bursts of vibration in a left-side or right-side ear cup to indicate that the user should turn left or right at the next intersection; may produce one sustained burst of vibration in a left-side or right-side ear cup to indicate that the user should merge left or right before the next highway lane event; and may produce three, sustained bursts of vibration to indicate that the user is approaching or has reached the destination, each of which may occur while the headphone device simultaneously generates the audible sound and tactile vibrations in response to the audio signal.
As yet another example of generating tactile feedback for a user while using the headphone device and computing device, a user may wear the headphone device connected to a computing device (e.g., a smartphone, portable video game console, or fitness tracker connected to a smartphone) while participating in adventure sports (e.g., snowboarding, skiing, skydiving, etc.). The computing device may include a GPS unit and other wireless signal transceivers for generation and processing of location data and the computing device or a peripheral device connected to the computing device may include an altimeter for generation and processing of altitude data.
The user may listen to one or more audio files (e.g., music, audiobooks, or radio programming, such as podcasts) while participating in the adventure sport. The headphone device may produce audible sound and tactile vibrations in response to receiving the audio signals associated with the audio files.
When an event relating to the adventure sport has occurred, such as, for example, a user crossing an altitude threshold (e.g., after which it is advisable to deploy a parachute), a feedback signal may be sent from the computing device to the headphone device. The feedback signal may cause the headphone device to generate tactile vibrations distinct from the tactile vibrations generated in response to the audio signal, such as, for example, a series of short bursts of vibration. Depending on the specific pattern of the tactile vibrations and the predetermined semantic meaning assigned to the specific pattern of the tactile vibrations, the user may understand that he or she should deploy a parachute. As specific, nonlimiting examples, the headphone device may produce five short bursts of vibration interspersed by long pauses to indicate that the user has crossed an upper threshold for deploying a parachute; may produce five short bursts of vibration interspersed by medium-length pauses to indicate that the user has crossed an middle threshold for deploying a parachute; and may produce five short bursts of vibration interspersed by short pauses to indicate that the user has crossed a lowest threshold for deploying a parachute, each of which may occur while the headphone device simultaneously generates the audible sound and tactile vibrations in response to the audio signal.
The headphone device 202 may include one or more speakers 214 and one or more tactile bass vibrators 216. For example, the headphone device 202 may include left-side and right-side speakers 214 and left-side and right-side tactile bass vibrators 216. The speakers 214 may be distinct from the tactile bass vibrators 216.
The left-side and right-side speakers 214 and left-side and right-side tactile bass vibrators 216 may be configured as, for example, over-the-ear, on-ear, in-concha, or in-ear earphones. The left-side and right-side speakers 214 and left-side and right-side tactile bass vibrators 216 may be located within housings 218 of the headphone device 202. The left-side and right-side speakers 214 may be configured to generate audible sound in response to audio signals sent from the computing device 204 to the headphone device 202. The left-side and right-side speakers 214 may not generate any audible sound or any tactile vibration in response to feedback signals sent from the computing device 204 to the headphone device 202. The left-side, right-side, or left-side and right-side tactile bass vibrators 216 may be configured to generate audible sound and tactile vibrations in response to audio signals and feedback signals sent from the computing device 204 to the headphone device 202.
In embodiments where the headphone device 202 exhibits an over-the-ear or an on-ear configuration, the housings 218 may define left-side and right-side ear cups 220 of the headphone device 202. In such embodiments, the headphone device 202 may include a headband 222 supporting the ear cups 220 and sized and shaped to rest on a user's head, and position the ear cups 220 proximate (e.g., over or on) the user's ears, when using the headphone device 202.
In some embodiments, the headphone device 202 may include an amplifier 224 operatively connected to the tactile bass vibrators 216. The amplifier 224 may be powered separately from the computing device 204. The amplifier 224 may be located, for example, within the one of the housings 218 of the headphone device 202, or an amplifier may be located in each housing 218 of the headphone device 202. As another example, the amplifier 224 may be located in-line with an audio cable 226 connecting the headphone device 202 to the computing device 204.

In addition, suitable headphone devices are commercially available from Skullcandy, Inc., of Park City, UT, under the trademark SKULLCRUSHERS®.
The signal splitter/controller 304 may further include control logic configured to modify the split audio signals 303 and 305, and optionally the feedback signal 311, responsive to a control signal 307. For example, the control signal 307 may control characteristics, such as volume. The signal splitter/controller 304 may be configured to control the first split audio signal 303, the second split audio signal 305, and optionally the feedback signal 311 independently. For example, a user may desire louder bass frequencies and a stronger tactile response at the bass frequencies, or a user may desire more intense, detectable haptic feedback relative to the volume of audio. As a result, more power may be supplied to the tactile bass vibrator 350 relative to the power supplied to the audio driver 340.
