And transmitting audio configuration information for the audio playback device via the proximity-based communication system.

Description

Technical Field

[0001] This disclosure generally relates to wireless communication of data. For example, aspects of the present disclosure relate to systems and techniques for audio profile configuration via proximity-based communication (e.g., Near Field Communication (NFC)). Background Art

[0002] Many devices and systems allow for the processing and output of audio data for consumption. Digital audio data can include a large amount of data to meet the demands of consumers. For example, consumers of audio data expect high-quality audio, including high-fidelity, high bitrate, lossless, etc. Additionally, many audio playback systems allow users to adjust how the audio data is played back. This adjustment ability allows audio consumers to adapt the audio playback to their different preferences for how they want to play back the audio. As an illustrative example, some consumers may prefer a neutral, relatively flat sound signature (e.g., frequency response) during playback. Other consumers may prefer enhanced bass and / or treble response. Another consumer may prefer processed audio to widen the soundstage or achieve spatial audio.

[0003] Generally, an audio playback system that allows a user to adjust how audio data is played back (e.g., playback settings or audio profiles) will remember the adjustments made by the user. For example, once the playback settings are adjusted for an audio playback system, these playback settings are retained if the audio device is turned off and then back on. While such an audio playback system can remember the audio playback settings, such a memory system may not be effective when dealing with multiple users who have their own audio playback settings. Thus, techniques for audio profile configuration may be needed. Summary of the Invention

[0027] Certain aspects and embodiments of the present disclosure are provided below. Some of these aspects and embodiments can be applied independently, and some of them can be applied in combination, which will be obvious to those skilled in the art. In the following description, for the purpose of explanation, specific details are set forth to provide a thorough understanding of the embodiments of the present application. However, it is obvious that various embodiments can be practiced without these specific details. The drawings and the description are not intended to be restrictive.

[0028] The following description only provides example embodiments and is not intended to limit the scope, applicability, or configuration of the present disclosure. Instead, the following description of the example embodiments will provide those skilled in the art with an enabling description for implementing the example embodiments. It should be understood that various changes can be made to the functions and arrangements of the elements without departing from the spirit and scope of the present application set forth in the appended claims.

[0029] Generally, one person can perceive audio differently from another person. For example, a sound that is perceived as pleasant by one person may be perceived as annoying or bothersome by another person. Therefore, a user may have specific preferences regarding how they like to play back audio and may want to be able to personalize the way audio is played back to them.

[0030] In some cases, sound effects (e.g., audio configurations) can be used to personalize audio playback for a user. For example, sound effects can be used to adjust the playback of audio data to personalize the playback according to their preferences. Modern audio playback devices typically have a wide range of sound effects that can be adjusted, such as bass, treble, full equalizer, volume, and audio processing effects (such as virtual playback modes (e.g., concert hall, theater, virtual surround, etc.), spatial audio, noise cancellation, etc.). In many cases, the audio playback device will store one or more previous audio configurations (e.g., the last audio configuration) applied by the user, which can prevent the user from having to readjust the audio configuration each time they listen to the audio playback device.

[0031] Although an audio playback device can store one or more previous audio configurations (e.g., the last audio configuration), when the audio playback device is shared by multiple users (or if a single user has multiple preferred audio configurations), retaining the (one or more) previous audio configurations for later use may not work well. For example, when a first user adjusts the audio configuration of an audio playback device and a second user starts using the audio playback device, the second user may not like the audio configuration applied by the first user and may want to readjust the audio configuration. This increased friction of having to change the audio configuration when different users use the audio playback device may discourage the use of shared audio playback devices or user-specific audio configurations.

[0032] This document describes systems, apparatuses, electronic devices, methods (also referred to as processes), and computer-readable media (collectively referred to herein as "systems and techniques") for applying audio configurations using a proximity-based communication system. In an illustrative example, the proximity-based communication system can include a Near Field Communication (NFC) system or other types of proximity-based communication systems. Although the NFC communication system is described herein as an illustrative example of a proximity-based communication system, in some aspects, the systems and techniques herein can utilize other types of proximity-based communication systems.

[0033] In some cases, using NFC application audio configuration can allow users to easily adjust the audio configuration to personalize audio playback. For example, the audio configuration information can be stored on an NFC card or other NFC-compatible devices, such as a smart phone, a tablet, an extended reality (XR) device (e.g., a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device), or other devices. When the NFC card or device is in close proximity to the audio playback device (e.g., within the near field of the transmitter), such as when it is called a proximity audio playback device, NFC can be used to provide the stored audio configuration information to the audio playback device. Then, the audio playback device can apply the received audio configuration information (e.g., by adjusting the sound effects applied to the audio being played back). In cases where the audio playback device and the NFC device also include other short-range connection capabilities via a radio access technology (e.g., Bluetooth TM connection), the audio playback device and the NFC device can be paired for the short-range connection radio access technology (e.g., Bluetooth TM connection) while receiving the audio configuration information.

[0034] Aspects of the present disclosure will be described with reference to the drawings. The aspects of the invention are initially described in the context of a multimedia system. Then, specific examples of devices and media processing systems for segmentation mask extrapolation are described. The aspects of the present disclosure are further illustrated and described with reference to device diagrams, system diagrams, and flowcharts related to segmentation mask extrapolation.

[0035] Figure 1 An example implementation of a system-on-chip (SOC) 100 is shown. The SOC 100 may include a central processing unit (CPU) 102 or a multi-core CPU configured to execute one or more functions described herein. Parameters or variables (e.g., neural signals and synaptic weights), system parameters associated with the computing device (e.g., a neural network with weights), latencies, frequency bin information, task information, and other information may be stored in a memory block associated with a neural processing unit (NPU) 108, in a memory block associated with the CPU 102, in a memory block associated with a graphics processing unit (GPU) 104, in a processor block associated with a digital signal memory (DSP) 106, in the memory block 118, and / or may be distributed across multiple blocks. Instructions executed at the CPU 102 may be loaded from a program memory associated with the CPU 102 or may be loaded from the memory block 118.

[0036] The SOC 100 may also include additional processing blocks customized for specific functions, such as the GPU 104, DSP 106, connectivity block 110 (which may include fifth-generation (5G) connectivity, fourth-generation long-term evolution (4G LTE) connectivity, Wi-Fi connectivity, USB connectivity, Bluetooth connectivity, NFC connectivity, etc.), and multimedia processor 112 (which may, for example, encode, decode, and / or transcode digital audio data and / or output audio). In one embodiment, the NPU is implemented in the CPU 102, DSP 106, and / or GPU 104. The SOC 100 may also include a sensor processor 114, an image signal processor (ISP) 116, and / or a navigation module 120, which may include a global positioning system.

[0037] The SOC 100 may be based on the ARM instruction set. The SOC 100 and / or its components may be configured to perform segmentation mask extrapolation. For example, the CPU 102, DSP 106, and / or GPU 104 may be configured to perform segmentation mask extrapolation via instructions included in a software application stored at least partially on the memory block 118.

[0038] Figure 2 A wireless communication system 200 configured for near-field communication (NFC) in accordance with aspects of the present disclosure is depicted. NFC may be considered a proximity-based communication system as an NFC transmitter, and the receiver communicates via a near-field radio frequency and can only operate over a short distance (e.g., within the near field of the transmitter). The wireless communication system 200 includes a transmitting component 202, which may be a component or block of a device (e.g., Figure 1 the connectivity block 110), and the transmitting component includes a transmitter 204 coupled to an antenna 206.

[0039] In a wireless communication system 200, an input power 208 can be provided to a transmitter 204 for generating a radiation field 210 for providing energy transfer. A receiver 212 of a receiving component 214 is coupled to the radiation field 210 and generates an output power. The input power 208 can be modulated to encode information for transmission via the radiation field 210 to the receiving component 214. The receiver 212 can demodulate the output power to receive the information and output 216 the received information for storage or consumption by a device (not shown) coupled to the output 216. The transmitter 204 and the receiver 212 can be separated by a distance 218. The transmitter 204 is coupled to a transmitting antenna 206 to provide a component for energy transfer. The receiver 212 is coupled to a receiving antenna 220 as a component for energy reception. The sizes of the transmitting antenna 206 and the receiving antenna 220 can be determined according to the associated applications and devices. In some cases, the transmitter 204 and the receiver 212 can be configured according to a mutual resonance relationship, and when the resonance frequency of the receiver 212 is similar to the resonance frequency of the transmitter 204, the transmission loss between the transmitter 204 and the receiver 212 can be minimized when the receiver 212 is located in the near field of the radiation field 210. The near field of the RF field can be a region relatively close to a conductor where the propagation of electromagnetic waves is disturbed.

[0040] In some cases, effective energy transfer can occur by coupling most of the energy in the near field of the transmitting antenna to the receiving antenna rather than propagating most of the energy in the electromagnetic wave to the far field. When in this near field, a coupling mode can be formed between the transmitting antenna 206 and the receiving antenna 220. The region where such near-field coupling may occur around the antennas 206 and 220 is referred to herein as the coupling mode region.

[0041] Figure 3 is a schematic diagram of a transmitter 302 and a receiver 304 of a near-field wireless communication system 300 according to aspects of the present disclosure. The transmitter 302 includes an oscillator 306, a power amplifier 308, and a filtering and matching circuit 310. The oscillator 306 can be configured to generate a signal at a desired frequency, which can be adjusted in response to an adjustment signal 312. The oscillator signal can be amplified by the power amplifier 308 by an amplification amount in response to a control signal 314. The filtering and matching circuit 310 can be included to filter out harmonics or other unwanted frequencies and match the impedance of the transmitter 302 to the transmitting antenna 316. The receiver 304 can include a matching circuit 318 coupled to a receiving antenna 322 and a rectifier and switching circuit 320 to generate an output 324. The matching circuit 318 can be included to match the impedance of the receiver 304 to the receiving antenna 322.

[0042] Figure 4FIG. 400 is a block diagram of components for an exemplary communication network in accordance with aspects of the present disclosure. In FIG. 400, communication device 410 may communicate with remote NFC endpoint 430 via antenna 424 using one or more NFC technologies (e.g., NFC-A, NFC-B, NFC-F, ISO-DEP, etc.). The remote NFC endpoint may be an NFC transceiver. Remote NFC endpoint 430 may include an NFC engine 432 for communicating via various interfaces (e.g., frame RF interface 434 and ISO-DEP RF interface 436). In some cases, communication device 410 and remote NFC endpoint 430 may use the ISO-DEP RF protocol to establish an ISO-DEP communication link.

[0043] Communication device 410 may include an NFC controller 412, a device host 440, and an NFC controller interface (NCI) 422. In some cases, device host 440 may be operable to obtain information from remote NFC endpoint 430 via NCI 422 and NFC controller 412, and via NFC engine 432 of remote NFC endpoint 430.

[0044] NFC controller 412 may include a frame RF interface 414 and an ISO-DEP RF interface 416. Frame RF interface 414 may include a data exchange engine 418. In some cases, during ISO-DEP communication, NFC controller 412 may operate using ISO-DEP RF interface 416. When operating using ISO-DEP RF interface 416, NFC controller 412 may be used to change various parameters associated with data exchange between device host 440 and remote NFC endpoint 430 using data exchange engine 418. In some cases, the NFC exchange format (NDEF) may be used to exchange data between communication device 410 and remote NFC endpoint 430.

[0045] Figure 5is a block diagram of an audio playback system 500 in accordance with aspects of the present disclosure. The audio playback system 500 can include a device 502 coupled to an audio playback device 504. In some cases, the device 502 can be any device capable of processing audio data and causing the audio data to be played back, such as a mobile device, a wearable device, an extended reality device (e.g., a virtual reality (VR) device, an augmented reality (AR) device, or a mixed reality (MR) device), a personal computer, a laptop computer, a video server, a vehicle, etc.). The audio playback device 504 can be any device capable of reproducing audio, such as a speaker, an audio system, a network-connected speaker, headphones, earbuds, a soundbar, etc. In some cases, the device 502 can include a digital audio data source 506 and an audio playback engine 508. The digital audio data source 506 provides digital audio data for playback. Examples of the digital audio data source 506 include locally stored audio data, such as audio data stored in Figure 1 the memory 116, or digital audio data streamed to the device 502 from a network server, a streaming audio service, or other networked devices. The audio playback engine 508 can receive the digital audio data from the digital audio data source 506 and convert the digital audio data from a storage format to another format compatible with the audio playback device 504. For example, the audio playback engine 508 can convert the digital data to an analog waveform for playback on a speaker. In another example, the audio playback engine 508 can convert the digital data from a storage format (such as the.mp3 format) to another digital data format (such as a Bluetooth audio format) for streaming to a Bluetooth audio device. In some cases, the audio playback engine 508 can also apply one or more transforms to the audio data. These transforms can adjust the sound effects (e.g., how the audio data is played back). Examples of these sound effects can include, but are not limited to, adjusting equalizer settings, adding bass emphasis, loudness / volume adjustment, adding effects, spatializing audio, etc.

[0046] In some cases, these sound effects (e.g., audio configurations) can be used to personalize audio playback for a user. For example, a user can be able to adjust the audio configuration of the audio data to adjust the playback of the audio data to their preferences. Thus, a first user can adjust the audio configuration to add bass and increase the volume, while a second user can adjust the audio configuration to achieve a more flat audio profile, where spatial audio effects are added to help virtually locate the audio playback around the second user. In another example, a single user can have multiple audio playback devices (such as headphones and earbuds), but may prefer a different audio configuration for the headphones compared to the earbuds.

[0047] Although an audio playback device may be able to remember the last audio configuration applied, in an audio playback device shared by multiple systems (or if a single user has multiple preferred audio configurations), when a first user adjusts the audio configuration of the audio playback, a second user may not like the applied audio configuration and may want to adjust the audio configuration again. This increased friction in having to change the audio configuration when different users use the audio playback device may discourage the use of the shared audio playback device or the use of user-specific audio configurations. In some cases, using NFC to apply an audio configuration can allow a user to easily adjust the audio configuration to personalize the audio playback.

[0048] In some cases, audio configuration information may be stored on an NFC card or other NFC-compatible device (such as a smart phone, tablet computer, etc.), and when the NFC card or device is in close proximity (e.g., within the near field of a transmitter), NFC can be used to provide this audio configuration information to the audio playback device. The audio playback device can then apply the received audio configuration information (e.g., by adjusting the sound effects applied to the audio being played back). In cases where the audio playback device and the NFC device also include an additional radio access technology (such as, Bluetooth TM connection), the audio playback device and the NFC device can be paired for the radio access technology (such as, Bluetooth TM connection) while receiving the audio configuration information. The audio configuration information can include one or more sound effects for adjusting the audio playback of the audio playback device.

[0049] Figure 6 is a flowchart 600 showing a process for audio profile configuration using near field communication according to aspects of the present disclosure. In some cases, a user may have an NFC device, such as an NFC-enabled mobile phone, an NFC-enabled tablet computer, an NFC card, etc., which includes one or more audio configurations for an audio playback device. In some cases, the audio configuration in the one or more audio configurations can be a default or common audio configuration that can be applied to one or more audio playback devices. In some cases, the audio configuration in the one or more audio configurations can be specific to certain audio playback devices.

[0050] At block 602, an NFC device can be tapped against the NFC antenna of an audio playback device. Bringing the NFC antenna of the NFC device into close proximity (e.g., within the near field of the NFC antenna) to the NFC antenna of the audio playback device can initiate an NFC transaction between the NFC device and the audio playback device. For example, the NFC device can detect that the NFC device has come into proximity with another NFC device (e.g., the audio playback device). At block 604, the NFC device can obtain handover information. For example, the NFC device can attempt to perform a handover operation to obtain Bluetooth pairing information (or other radio access technology pairing) from the audio playback device. In some cases, the audio playback device can be an active NFC device (e.g., an NFC device rather than a static NFC tag), and the NFC device can perform a negotiated handover by requesting handover information from the audio playback device. In some cases, the handover information can include information about the audio playback device, such as an identifier (e.g., MAC_ID) and / or an indication that the audio playback device supports audio profile configuration via NFC.

[0051] At block 606, if the handover information includes Bluetooth information, the execution can proceed to block 608, where Bluetooth information can be obtained from the audio playback device. For example, the audio playback device can respond to the handover request with a handover selection message that indicates one or more alternative radio access technologies (e.g., Bluetooth, Wi-Fi, etc.) that the audio playback device supports switching to. In the case where the audio playback device indicates that it supports switching to Bluetooth, the NFC device can request the Bluetooth information for pairing the devices. After obtaining the Bluetooth information, the execution can proceed to block 610.

[0052] At block 606, if the handover information does not include Bluetooth information, the execution can proceed to block 610. For example, if the audio playback device does not support switching to Bluetooth, the audio playback device can send a handover selection message indicating that the audio playback device does not support Bluetooth. In some cases, if the audio playback device does not support switching to Bluetooth, the audio playback device may not directly respond to the handover request from the NFC device. In some cases, the audio playback device can send a request for information from the NFC system instead of a direct response to the handover request. In some cases, the request for information can include information about the audio playback device, such as an identifier (e.g., MAC_ID) and / or an indication that the audio playback device supports audio profile configuration via NFC.

[0053] At block 610, the NFC system can request audio configuration information from the NFC device. For example, an audio playback device can request NDEF information from the NFC device via an NFC connection. In some cases, the request can indicate that the request is for audio configuration information. In some examples, the audio configuration request can include identification information of the audio playback device. The NFC device can respond to the request for audio configuration information by sending the audio configuration information. In some cases, the audio configuration information can be general or default audio configuration information that can be applied to multiple audio playback devices. In other cases, the audio configuration information can be specific to a particular audio playback device. For example, the audio configuration request can include identification information of the audio playback device, and the NFC device can retrieve the audio configuration information based on the identification information.

[0054] In some cases, the audio configuration information can be transmitted via an NFC connection instead of Bluetooth (if available), because Bluetooth can automatically connect to the last connected device or can perform unpairing / pairing operations to connect Bluetooth to a different audio source (e.g., the NFC system). With NFC, a single action (e.g., a tap) from the user can be used to perform the Bluetooth pairing operation and the transmission of the audio configuration information, which can simplify the user experience.

[0055] At block 612, the audio playback device may receive audio configuration information. For example, the audio playback device may receive NDEF information including audio configuration information from an NFC device. At block 614, the audio playback device may compare the received audio configuration information with the current audio configuration of the audio playback device. If the received audio configuration information does not match the current audio configuration of the audio playback device, the execution may proceed to block 616. At block 616, the current audio configuration of the audio playback device may be adjusted based on the received audio configuration. In some cases, the audio configuration may include configurations that the audio playback device may not support. For example, if the received audio configuration indicates that enhanced bass features should be activated, but the audio playback device does not support enhanced bass features. In such a case, the specific configuration may be ignored. In some cases, if certain audio configurations cannot be applied, are not successfully applied, or are successfully applied, the audio playback device may visually prompt the user via a display or prompt the user via one or more audio cues. In some cases, the audio playback device may be configured to adjust another feature as the best fit for the unsupported feature. Expanding on the above example, if the audio playback device does not support enhanced bass features, but the audio playback device supports equalizer settings, the audio playback device may adjust the equalizer settings to increase the bass for audio playback. The exact feature that is adjusted to the best fit, the exact settings of such a best fit feature, and how to handle potentially conflicting features (e.g., the received audio configuration to activate enhanced bass and the equalizer configuration to reduce bass) may be implementation-specific and vary between audio playback devices. After adjusting the audio configuration, the execution may proceed to block 618, where audio may be played back based on the current audio configuration.

[0056] At block 614, if the comparison between the received audio configuration information and the current audio configuration of the audio playback device indicates that the received audio configuration information matches the current audio configuration, the execution may proceed to block 618, where audio may be played back based on the current audio configuration. In the case of obtaining Bluetooth information from the audio system at block 608, a switching operation may be performed to establish a Bluetooth connection (e.g., pairing). In such a case, the audio configuration information may be sent via NFC.

[0057] As described above, in some cases, the audio configuration information may be specific to a particular audio playback device. Figure 7Table 700 illustrates audio configuration information for multiple audio playback devices according to aspects of the present invention. In some cases, an NFC device may have multiple users, and these multiple users may have audio configuration information specified for one or more audio playback devices. For example, Table 700 may be associated with an NFC device having two users (user_a1 and user_b1). User_b1 may have a single audio configuration for an audio playback device having the device identifier sound_bar1.
