Description

BACKGROUND

Field of the Disclosure

The disclosure relates generally to an information handling system, and in particular, controlling audio of an information handling system.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Modern & emerging devices such as large form factor foldable PCUs (personal computing units) need to provide appropriate audio and voice user experience for the multiple use cases by a user.

Turning to FIG. 2, FIG. 2 illustrates an environment 200 including an information handling system 202 and a mobile computing device 204. The information handling system 202 can include an audio management computing module 206, a speaker array 208, a camera module 210, a microphone array 212, and a location detection computing module 213. In some examples, the information handling system 202 is similar to, or includes, the information handling system 100 of FIG. 1.

The speaker array 208 can include a plurality of speakers 214a, 214b, 214c, 214d (collectively referred to as speakers 214); however, the speaker array 208 can include any number of speakers. Each of the speakers 214 can be full-audio frequency speakers. That is, each of the speakers 214 is capable of producing i) high frequency sounds (e.g., 2 kHz-20 kHz) (commonly referred to as “tweeters”) and ii) low frequency sounds (e.g., 20-200 Hz) (commonly referred to as “subwoofers”). The speakers 214 are able to dynamically switch frequency (e.g., from high frequency to low frequency and vice versa) based on a location of a user 220 associated with the information handling system 202 (using/engaging with the information handling system 202), described further herein. Furthermore, the speakers 214 are able to dynamically switch channel (e.g., from right channel to left channel and vice versa) based on the location of the user 220, described further herein. In some examples, the speakers 214 are physically located at one or more sides (edges) of the information handling system 202, as shown in FIG. 4. However, the speakers 214 can be physically positioned anywhere along the information handling system 202, depending on the application desired.

The microphone array 212 can include a plurality of microphones 222a, 222b, 222c, 222d (collectively referred to as microphones 222); however, the microphone array 212 can include any number of microphones. Differing subsets of the microphones 222 can be selected for use by the information handling system 202 in furtherance of detecting sounds (e.g., by the user 220) based on the location of the user 220 to beamform the microphone array 212 to the user, described further herein. In some examples, the microphones 222 are physically located at a particular surface of the information handling system 202, as shown in FIG. 4. However, the microphones 222 can be physically positioned anywhere about the information handling system 202, depending on the application desired.

The camera module 210 can include an integrated camera (webcam) or an external camera to the information handling system 202. The camera module 210 can be associated with a field of view—e.g., a portion of the (physical) environment 200 that is visible to the camera module 210 (through the camera module 210) at a particular position and orientation of the camera module 210 in the environment 200 and with respect to the information handling system 202. In some examples, the camera module 210 can include a RGB camera, or an IR camera. In some examples, the camera module 210 is physically located at a particular surface of the information handling system 202, as shown in FIG. 4. However, the camera module 210 can be physically positioned anywhere about the information handling system 202, depending on the application desired.

The location detection computing module 213 can be in communication with the mobile computing device 204.

FIG. 3 illustrates a flowchart depicting selected elements of an embodiment of a method 300 for controlling audio of an information handling system. The method 300 may be performed by the information handling system 100, the information handling system 202, the audio management computing module 206, and/or the location detection computing module 213, and with reference to FIGS. 1-2 and 4-10. It is noted that certain operations described in method 300 may be optional or may be rearranged in different embodiments

The location detection computing module 213 can identify a first location of the user 220 with respect to the information handling system 202, at 302. Referring to FIG. 4, in some examples, the camera module 210 can detect the first location of the user 220. That is, the user 220 can be within the field of view of the camera module 210 such that the camera module 210 can provide data indicating such to the location detection computing module 213. The data can include an image (RGB, IR, or other) of the user 220 with respect to the environment 200. The location detection computing module 213 can process the data from the camera module 210 to identify the first location of the user 220 with respect to the information handling system 202. In some examples, the camera module 210 can transmit the data indicating the first location of the user 220 automatically (e.g., every 1 second, 1 minute), or in response to a request from the location detection computing module 213.

In some examples, the location detection computing module 213 can determine the first location of the user 220 based on a location of the mobile computing device 204 with respect to the information handling system 202. That is, the mobile computing device 204 can provide a location signal to the location detection computing module 213. The location detection computing module 213 can process the location signal to determine the location of the mobile computing device 204 with respect to the information handling system 202, and thus, the first location of the user 220 (as the mobile computing device 204 is associated with the user 220). That is, the location of the user 220 can be similar to, or substantially the same as, the location of the mobile computing device 204 (the location of the user 220 with respect to the information handling system 202 is equated with the location of the mobile computing device 204 with respect to the information handling system 202). Specifically, based on an intensity of the location signal and/or a time to transmit the location signal from the mobile computing device 204 and to receive the location signal at the location detection computing module 213, the location detection computing module 213 can determine the location of the mobile computing device 204 with respect to the information handling system 202. In some examples, the location signal is a Wi-Fi signal, a Bluetooth signal, or an ultra-wide band (UWB) signal.

The location detection computing module 213 can transmit data indicating the first location of the user 220 to the audio management computing module 206.

The audio management computing module 206 calculates a first configuration of the speakers 214 based on the first location of the user 230, at 304. A configuration of the speakers 214 can include a frequency range of each respective speaker, a channel of each respective speaker, and a power (or volume level) of each respective speaker. Referring to FIG. 4, specifically, the first configuration of the speakers 214 can include the speaker 214a associated with a High frequency (tweeter), a left channel, and a respective power; the speaker 214b associated with a high frequency (tweeter), right channel, and a respective power; the speaker 214c associated with a low frequency (subwoofer), left channel, and a respective power; and the speaker 214d associated with a low frequency (subwoofer), Right channel, and a respective power. That is, the first configuration of the speakers 214—frequency of each speaker 214, channel of each speaker 214, and power (or volume level) of each speaker 214—is set (or configured) based on the first location of the user 230. That is, the first configuration of the speakers 214 can be based on the location of the user 220 to optimize the “experience” of the user 220—optimize the sound quality, sounds levels, or other sound metrics of the speakers 214 for the first location of the user 220.

The audio management computing module 206 can further calculate a first configuration of the microphone array 212 based on the first location of the user 220, at 306. A configuration of the microphone array 212 can include selecting a subset of the microphones 222 to microphone beamform based on the first location of the user 220. Referring to FIG. 4, specifically, the first configuration of the microphone array 212 can include selecting a first subset of the microphones 222—e.g., the microphones 222b, 222c that are closest to the user 220. However, in some examples, any subset of the microphones 222 can be selected for the first subset of microphones 222. The audio management computing module 206 can apply a beamforming algorithm to the first subset of microphones 222 (e.g., upon detection of speech from the user 220).

The audio management computing module 206 can identify a context of the user 220 with respect to the information handling system 202, and a context of the information handling system 202, at 308. The context of the information handling system 202 can include a location of the information handling system 202. For example, the location of the information handling system 202 can include the type of environment 200—e.g., a home environment, or a work environment. The context of the information handling system 202 can include a time, and devices proximate to the information handling system (e.g., the mobile computing device 204).

The location detection computing module 213 can identify a change in the location of the user 220 from the first location with respect to the information handling system 202, at 310. In particular, the location of the user 220 with respect to the information handling system 202 is not consistent—the user 220 moves about the environment 200. For example, depending on the posture of the information handling system 202 (e.g., table-top posture mode, book posture mode, tent posture mode) and how the user 220 interacts with/uses the information handing system 202, the user 220 can change his/her location from the first location with respect to the information handling system 202. Furthermore, when detecting the change in location of the user 220 with respect to the information handling system 202, the location detection computing module 213 can further determine that a location of the information handling system 202 has not changed. Specifically, the information handling system 202 can include an inertia sensor (not shown) (or gyroscope) and a hinge angle sensor (not shown) (defined between bodies of the information handling system 202). The location detection computing module 213 can receive signals form the inertia sensor and the hinge angle sensor indicating zero (or little) movement, and thus, no location change of the information handling system 202.

Specifically, identifying the change in the location of the user 220 can include, and further, in response to such change in location of the user 220, the location detection computing module 213 can determine whether the user 220 is within the field of view of the camera module 210, at 312. In particular, the location detection computing module 213 can receive a signal from the camera module 210 indicating that the user 220 is within the field of view of the camera module 210.

The location detection computing module 213 can determine that the user 220 is within the field of view of the camera module 210, as shown in FIG. 5. In response to determining that the user 220 is within the field of view of the camera module 210, the location detection computing module 213 determines a second location of the user 220 with respect to the information handling system 202, at 314 (e.g., within 1 meter of the information handling system 202). The location detection computing module 213 can provide the data indicating the second location of the user 220 to the audio management computing module 206. The audio management computing module 206 can calculate a second configuration of the speakers 214 based on the second location of the user 220, at 316. Specifically, the second configuration of the speakers 214 can include the speaker 214a associated with a low frequency (subwoofer), a left channel, and a respective power; the speaker 214b associated with a high frequency (tweeter), left channel, and a respective power; the speaker 214c associated with a low frequency (subwoofer), Right channel, and a respective power; and the speaker 214d associated with a high frequency (tweeter), right channel, and a respective power. That is, the second configuration of the speakers 214—frequency of each speaker 214, channel of each speaker 214, and power (or volume level) of each speaker 214—is set (or configured) based on the second location of the user 230. That is, the second configuration of the speakers 214 can be based on the second location of the user 220 to optimize the “experience” of the user 220—optimize the sound quality, sound levels, or other sound metric of the speakers 214 for the second location of the user 220. In some examples, the second configuration of the speakers 214 is further based on the context of the user 220 with respect to the information handling system 202, and/or the context of the information handling system 202.

Further in response to identifying the change in location of the user 220, the audio management computing module 206 can calculate a second configuration of the microphone array 212 based on the second location of the user 220, at 318. Referring to FIG. 5, specifically, the second configuration of the microphone array 212 can include selecting a second subset of the microphones 222—e.g., the microphones 222a, 222b, 222c, that are closest to the user 220. However, in some examples, any number of the microphones 222 can be selected for the second subset of microphones 222. The audio management computing module 206 can apply a beamforming algorithm to the second subset of microphones 222 (e.g., upon detection of speech from the user 220).

The location detection computing module 213 can determine that the user 220 is not within the field of view of the camera module 210 (at 312). In particular, the location detection computing module 213 can receive a signal from the camera module 210 indicating that the user 220 is not within the field of view of the camera module 210 (or not receive a signal from the camera module 210 indicating that the user 220 is within the field of view of the camera module 210). In response to determining that the user 220 is not within the field of view of the camera module 210, the location detection computing module 213 determines a third location of the user 220 with respect to the information handling system 202, at 320. Specifically, the location detection computing module 213 can determine the third location of the user 220 based on a location of the mobile computing device 204 with respect to the information handling system 202 (e.g., within 1-3 meters of the information handling system 202). That is, the mobile computing device 204 can provide a location signal to the location detection computing module 213. The location detection computing module 213 can process the location signal to determine the location of the mobile computing device 204 with respect to the information handling system 202, and thus, the third location of the user 220 (as the mobile computing device 204 is associated with the user 220).

The location detection computing module 213 can provide the data indicating the third location of the user 220 to the audio management computing module 206. The audio management computing module 206 can then calculate a distance between the third location of the user 220 and the information handling system 202, at 322. The audio management computing module 206 can determine whether the distance between the third location of the user 220 and the information handling system 202 is less than a first threshold, at 324. For example, the first threshold is three meters.

When the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is less than the first threshold, the audio management computing module 206 can calculate a third configuration of the speakers 214 based on the third location of the user 220, at 326, as shown in FIG. 6. Specifically, the third configuration of the speakers 214 can include the speaker 214a associated with a low frequency (subwoofer), a left channel, and a respective power; the speaker 214b associated with a high frequency (tweeter), left channel, and a respective power; the speaker 214c associated with a low frequency (subwoofer), right channel, and a respective power; and the speaker 214d associated with a high frequency (tweeter), right channel, and a respective power. That is, the third configuration of the speakers 214—frequency of each speaker 214, channel of each speaker 214, and power (or volume level) of each speaker 214—is set (or configured) based on the third location of the user 230. That is, the third configuration of the speakers 214 can be based on the third location of the user 220 to optimize the “experience” of the user 220—optimize the sound quality, sounds levels, or other sound metric of the speakers 214 for the third location of the user 220. In some examples, the third configuration of the speakers 214 is further based on the context of the user 220 with respect to the information handling system 202, and/or the context of the information handling system 202.

When the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is greater than the first threshold, the audio management computing module 206 determines whether the distance between the third location of the user 220 and the information handling system 202 is less than a second threshold (and greater than the first threshold), at 328. When the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is less than the second threshold (and greater than the first threshold), the audio management computing module 206 can calculate a fourth configuration of the speakers 214 based on the third location of the user 220, at 330, as shown in FIG. 7. Specifically, the fourth configuration of the speakers 214 can include the speaker 214a associated with a low frequency (subwoofer), a left channel, and a respective power; the speaker 214b associated with a high frequency (tweeter), left channel, and a respective power; the speaker 214c associated with a low frequency (subwoofer), right channel, and a respective power; and the speaker 214d associated with a high frequency (tweeter), right channel, and a respective power. That is, the fourth configuration of the speakers 214—frequency of each speaker 214, channel of each speaker 214, and power (or volume level) of each speaker 214—is set (or configured) based on the third location of the user 230. That is, the fourth configuration of the speakers 214 can be based on the third location of the user 220 to optimize the “experience” of the user 220—optimize the sound quality, sound levels, or other sound metric of the speakers 214 for the third location of the user 220. In some examples, the fourth configuration of the speakers 214 is further based on the context of the user 220 with respect to the information handling system 202, and/or the context of the information handling system 202.

Additionally, when the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is less than the second threshold (and greater than the first threshold), the audio management computing module 206 can increase a gain of the second subset of microphones 222, at 332. That is, as the user 220 moves further from the information handling system 202 (e.g., between three and five meters), the gain of the microphones 222 is increased for increase quality of sound reception.

When the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is greater than the second threshold (e.g., five meters), the audio management computing module 206 can adjust the power state of the speakers 214 and the microphone array 212 to an off-power state, at 334, as shown in FIG. 8. For example, when the user 220 is “out-of-range” of the speakers 214 and/or the microphone array 212, the audio management computing module 206 can adjust the power state of the speakers 214 and the microphone array 212 to the off-power state. In some examples, the second threshold can be customized by the user 220, or pre-defined (e.g., by a manufacturer of the information handling system 202).

In some examples, when the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is greater than the second threshold (e.g., five meters), the audio management computing module 206 can “handover” the audio signal to the mobile computing device 204. That is, the audio management computing module 206 can switch from providing audio from the speakers 214 to providing audio through the mobile computing device 204 (e.g., speakers of the mobile computing device 204). In some examples, when the audio management computing module 206 determines that the distance between the third location of the user 220 and the information handling system 202 is greater than the second threshold (e.g., five meters), the audio management computing module 206 can i) transfer the audio signal to the mobile computing device 204 (e.g., the speakers of the mobile computing device 204 are in a powered-on state to generate sound) and ii) can adjust the power state of the speakers 214 and the microphone array 212 to an off-power state.

FIG. 9 illustrates a graph 900 of the audio output power of any of the speakers 214. Specifically, the graph 900 illustrates, for a speaker 214, the power of the speaker 214 (in terms of percentage increase) versus the distance of the user 220 from the information handling system 202. For example, for the user distance less than 1 meter (e.g., as shown in FIG. 5), the power of the speakers is the same as the settings provided by the information handling system 202 (initial settings). For the user distance between 1 meter and 3 meters (as shown in FIG. 6), the power of the speakers 214 are tuned up, with the power of the speakers 214 at the high frequency (e.g., tweeters) are increased at a slightly larger pace. For the user distance between 3 meters and 5 meters (as shown in FIG. 7), the power of the speakers 214 are further tuned up (increased), with the power of the speakers 214 at the high frequency (e.g., tweeters) are increased at a much larger pace. For the user distance greater than 5 meters (as shown in FIG. 8), the speakers 214 are in a power-off state.

In some examples, when the speakers 214 are in the second configuration, the power of the speakers 214 are greater than the power of the speakers 214 in the first configuration.

In some examples, when the speakers 214 are in the third configuration, the power of the speakers 214 are greater than the power of the speakers 214 in the second configuration.

In some examples, when the speakers 214 are in the fourth configuration, the power of the speakers 214 are greater than the power of the speakers 214 in the third configuration.

FIG. 10 illustrates the environment 200 including the user 220 and an additional user 1020. The additional user 1020 can be associated with an additional mobile computing device 1004. To that end, the camera module 210 can detect the presence of the user 220 and the additional user 1020, similar to that described above with respect to FIGS. 4 and 5. The distances of each of the users 220, 1020 can be determined by the location detection computing module 213, similar to that described above with respect to FIGS. 6-8. The audio management computing module 206, in response to the respective distances of the users 220, 1020, can calculate a fifth configuration of the speakers 214 based on the respective locations of the user 220, 1020. That is, the fifth configuration of the speakers 214—frequency of each speaker 214, channel of each speaker 214, and power (or volume level) of each speaker 214—is set (or configured) based on the locations of each of the users 220, 1020. In some examples, the fifth configuration of the speakers 214 is further based on the context of the users 220, 1020 with respect to the information handling system 202, and/or the context of the information handling system 202.

The audio management computing module 206 can further calculate a third configuration of the microphone array 212 based on the locations of the user 220, 1020. Specifically, the third configuration of the microphone array 212 can include selecting a first subset of the microphones 222—e.g., the microphones 222a, 222b that are closest to the user 220; and a second subset of the microphones 222—e.g., the microphones 222c, 222d that are closed the user 1020. The audio management computing module 206 can apply a beamforming algorithm to the first subset of microphones 222 for the user 220 (e.g., upon detection of speech from the user 220); and apply a beamforming algorithm to the second subset of microphones 222 for the user 1020 (e.g., upon detection of speech from the user 1020).
