Description

Technical Field

[0001] The present disclosure relates to the technical field of audio processing, and in particular to an electronic device and an audio output method. Background Art

[0002] During a video conference, the microphone volume on the far end may be too low. To improve this, users can use headphones, but when they switch back to the speaker, the volume suddenly becomes too loud, causing hearing discomfort.

[0003] The current solution is for users to speak as close to the microphone as possible to increase sound pickup sensitivity, while also manually adjusting the volume to accommodate speaker variations. However, this approach has limitations. First, users must constantly adjust their position and volume, which is complex and inconvenient, and can easily interrupt the meeting flow. Second, this manual adjustment method can cause additional frustration for users unfamiliar with device settings, impacting the overall meeting experience and efficiency. Summary of the Invention

[0025] To make the purposes, features, and advantages of the present disclosure more apparent and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them.

[0029] It should be understood that in the various embodiments of the present disclosure, the size of the serial number of each implementation process does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present disclosure.

[0030] Figure 1 A schematic diagram of the structure of an electronic device according to an embodiment of the present disclosure is shown. Figure 1 As shown, the electronic device includes:

[0031] A connecting unit, configured to connect to a target device to obtain a sound signal output by the target device;

[0032] a sound output unit, configured to output the sound signal;

[0033] a processing unit, configured to determine an output mode of the sound output unit, and adjust output parameters of the sound signal according to switching of the output mode of the sound output unit, so that an auditory effect of the sound signal in different output modes of the sound output unit satisfies a matching condition;

[0034] The sound output unit includes a plurality of different sound output modules, and the sound output unit outputs sounds based on different sound output modules in different output modes.

[0035] Here, the electronic device may be a display device including a connection unit, a sound output unit, and a processing unit. The display device is connected to a target device via the connection unit to obtain a sound signal output by the target device. The display device may be a monitor, a television, a projector, a tablet computer, etc., and the target device may be a computer, a mobile phone, a tablet computer, etc.

[0036] The received sound signal is output by a sound output unit, which may include multiple sound output modules. The sound output module may be a speaker, a Bluetooth speaker, a headset, etc., and supports switching different output modes as needed, that is, in different output modes, the electronic device uses the switched sound output module to output the sound signal, thereby providing appropriate sound effects according to the usage scenario. In addition, the processing unit can dynamically adjust the output parameters of the audio signal, such as volume, frequency response, etc., according to the output mode selected by the user (such as through a speaker or headset), to ensure that the sound effect can meet the predetermined auditory matching conditions in different output modes, thereby improving the user experience.

[0037] In this way, in different output modes, the display device will switch to the corresponding sound output module and provide appropriate output parameters of the sound signal, thereby providing appropriate sound effects according to the usage scenario.

[0038] In some embodiments, the electronic device further comprises:

[0039] An image acquisition unit, used for acquiring images within a target area;

[0040] The processing unit is further configured to determine the position information of the target object based on the captured image; and in response to the output mode switching, adjust the output parameters of the sound signal based on the position information of the target object.

[0041] Here, the image acquisition unit is used to acquire images within the target area in real time, for example, by using a camera, a sensor, or other image capturing devices.

[0042] The target object can move within a certain area and may appear in the target area. The image acquisition unit can monitor the dynamics of objects, target objects, and people in the target area. For example, in a smart TV or projector scenario, the camera can capture the position or movement of the target object (such as the audience) to determine whether the target object appears in the target area and its location information within the target area.

[0043] Here, the processing unit can be used to identify image data and determine the location information of the target object based on the collected image data; and, based on the different output modes selected by the user (such as using speakers, headphones or Bluetooth speakers to output sound), dynamically adjust the output parameters of the sound signal in combination with the location information of the target object to ensure that no matter how the user switches the output mode, the sound can adapt to the new device environment and ensure the best sound effect.

[0044] For example, when the target subject switches the output mode, specifically from a speaker to headphones, while participating in a meeting, the audio settings are adjusted based on the target subject's location information, the volume of the sound signal, and other characteristics to ensure that the sound output matches the user's location.

[0045] For example, when watching a movie, the sound effects will be adjusted according to the position of the target object, and surround sound effects can be used to make the sound sound more three-dimensional and realistic.

[0046] For another example, when the target object (such as a user or audience) moves, if the target object is close to the electronic device, the output parameters are adjusted to reduce the volume, while if it is far away from the device, the sound is enhanced to ensure that the sound quality always meets the user's needs.

[0047] Here, the processing unit may be a computer vision, deep learning or image recognition algorithm to recognize and track the face and body of the target object and determine its position.

[0048] In one example, the processing unit can use a face recognition model to detect the face position of a target object (e.g., a user) in an image, or use a human posture recognition model to detect and track key points of the target object (e.g., head, shoulders, elbows, knees, etc.) to identify the user's position and movement. Then, using background modeling techniques (e.g., background subtraction algorithms), the user is separated from the image and the user's position is inferred.

[0049] In another example, a reference object may be set in the target area, and the distance between the target object and the reference object may be identified through the recognition model to infer the position information of the target object.

[0050] In another example, two or more cameras are used to capture images from different angles, and parallax (i.e., the position change of the same object in different camera perspectives) is used to estimate the distance and direction of the target object from the camera.

[0051] Of course, other technologies may also be used to identify location information, which is not limited here.

[0052] In this way, by adjusting the audio output according to the position information of the target object, a better experience can be provided to the user.

[0053] In some embodiments, the electronic device further comprises: an image output unit configured to output an image along a first direction;

[0054] The first sound output module is provided at one side of the image output unit along a direction that satisfies a condition opposite to the first direction. The first sound output module is one of the multiple different sound output modules.

[0055] Here, the image output unit is used to display images or content, and output images along a first direction, which may be a display screen of an electronic device, and the first direction is the display direction of the display screen.

[0056] The multiple different sound output modules include a first sound output module, which is an audio output component of the electronic device for playing sound. The electronic device can adopt under-screen sound technology to hide the sound output module under the display screen. Here, the direction of the first sound output module is opposite to the display direction, or at least the direction that meets the opposite conditions, that is, the first sound output module is hidden or integrated under the display screen for playing sound. In this way, space can be greatly saved and traditional speakers can be prevented from taking up additional space.

[0057] In some embodiments, the processing unit is configured to determine an adjustment parameter of the sound signal based on the second sound output module that outputs the sound before the output mode is switched and the third sound output module that outputs the sound after the output mode is switched;

[0058] Adjusting the sound signal based on the adjustment parameter to obtain an adjusted sound signal;

[0059] The adjusted sound signal is output to the third sound output module, so that the auditory effect of the sound output by the third sound output module matches that of the third sound output module.

[0060] Here, the electronic device has multiple sound output modules. The sound output module before the output mode is switched is called the second sound output module, and the sound output module after the output mode is switched is called the third sound output module. For example, the output mode before switching can be a speaker, and the output mode after switching can be headphones, etc.

[0061] Here, the adjustment parameters may include volume, sound effects and other settings to adapt to the new output mode.

[0062] For example, after the processing unit determines the required adjustment parameters based on the second sound output module and the third sound output module, it adjusts the original sound signal based on the adjustment parameters, which may include: increasing or decreasing the volume, adjusting the frequency range (for example, increasing bass or increasing treble), applying certain sound effects (such as echo, reverberation, etc.), etc. The adjusted sound signal is an optimized and processed sound, which is suitable for the current output mode and the third sound output module.

[0063] Here, the electronic device may pre-design and store a parameter relationship table, which includes correspondences between parameters such as volume and sound effects. Taking volume as an example, the volume relationship table may be used to indicate the volume used by different sound output modules corresponding to at least one musical scale. For example, Table 1 shows a volume relationship table.

[0064] Table 1 divides the volume levels of headphones and speakers into 25 levels. For example, when the headphone volume is at level 10, if you unplug the headphones, the speaker volume will also be adjusted to level 10. Conversely, if the speaker volume is at level 11, plugging in the headphones will automatically set the headphone volume to level 11.

[0065]

[0066]

[0067] Table 1

[0068] Among them, the display menu selection range indicates the volume selection range displayed on the user side. Different volume ranges correspond to the volume used by the respective headphones and speakers. "..." Different volumes can be set based on demand. Some scales provide a volume example. For example, when the 10th scale of the headphones corresponds to 60db, and the 10th scale of the speaker corresponds to 70db, the same syllable conversion process can be converted through 3db / s to avoid the trouble caused by the sound being too loud or too small. For example, after unplugging the headphones, the volume gradually increases or decreases from 63db in the first second to 66db in the second second. It should be noted that the numbers given for the above volume, selection range, etc. are an example, which is only used here to illustrate a design scheme, and the specific values therein are not limited.

[0069] In this way, the sound signal is adjusted according to different output modes (for different sound output modules) to ensure that the final output sound effect matches the corresponding sound output module, thereby optimizing the sound effect and providing the best auditory experience.

[0070] In some embodiments, the processing unit is configured to adjust an output parameter of the sound signal in response to a change in the distance between the target object and the electronic device satisfying a preset distance.

[0071] Here, the electronic device can capture images within the target area through an image capture unit; the processing unit determines the location information of the target object based on the captured image; if the distance change between the target object and the electronic device meets the preset distance, the output parameters of the sound signal can be adjusted according to the distance.

[0072] The target object may refer to an object or person, such as a user, an audience, or an object, and the distance between the target object and the electronic device may vary.

[0073] The preset distance is a set distance threshold or standard distance. When the distance between the target object and the electronic device changes and reaches the preset distance, the output parameter can be adjusted.

[0074] Output parameters can include:

[0075] Volume, for example, when the distance is close, you may need to lower the volume; when the distance is far, you may need to increase the volume;

[0076] Sound quality, for example, changes in distance can affect the propagation of sound and adjust the enhancement of high or low frequencies;

[0077] Channel allocation, for example, can adjust the stereo effect, change the directionality of the sound or the channel allocation when using speakers, based on the relative position of the target object and the electronic device.

[0078] Taking volume as an example, the required volume can be determined based on the distance. As shown in Table 2, different volume levels are selected based on different distance relationships.

[0079] distance volume 0cm 0db 10cm 20db 20cm 30db 40cm 50db 50cm 70db 60cm 71db 70cm 72db 80cm 73db 90cm 75db 100cm 76db 110cm 78db 120cm 79db

[0080] Table 2

[0081] In this way, the processing unit adjusts the output parameters of the sound according to the change in the distance between the target object and the electronic device to ensure that the user obtains the best auditory experience.

[0082] In some embodiments, the electronic device further comprises: at least two sound collection units for collecting sound; the collection areas of the at least two sound collection units overlap;

[0083] The processing unit is further configured to enhance the volume of the sound portion of the target object if the target object appears in the overlapping collection area.

[0084] Here, the sound collection unit may be a microphone, a sound wave sensor, etc., and the sound collection unit may be integrated with the sound output module.

[0085] The overlapping area refers to the overlapping part of the collection areas of at least two sound collection units. In the configuration of multiple microphones or sound collection units, the overlapping area exists in the area that can be perceived at the same time. For example, when the pickup ranges of two microphones intersect, the sound from a target object can be captured at the same time. Figure 2 As shown, there is an intersection between the two microphones (Mic1 and Mic2), namely the range of Mic3.

[0086] When a target object appears in overlapping collection areas, the processing unit performs volume enhancement, which may include increasing the volume and clarity of the target object's voice to make it more prominent. For example, if the voice of a target object (such as a user) appears in the overlapping area of two sound collection units, the processing unit identifies and enhances the target object's voice. In this way, the target object's voice can be highlighted in an environment with multiple sound sources or background noise, ensuring that the target sound is clearer or easier to hear.

[0087] In some embodiments, the processing unit is configured to perform sound source separation on the collected sound to obtain at least one sound part;

[0088] Perform voiceprint recognition on each of the sound parts, and determine the sound part corresponding to the target object according to the voiceprint recognition result.

[0089] Here, a method for identifying the sound of a target object is provided. A sound collection unit captures sound signals in the environment (which may include multiple sound sources simultaneously, such as people talking, fan noise, and other background noise). A processing unit uses sound source separation technology to separate the sound sources and obtain multiple sound source components. Sound source separation refers to separating a mixed sound signal into different sound components, each representing an independent sound source. Sound source separation technology can use blind signal separation (BSS) or beamforming technology, and the specific method used is not limited here.

[0090] Voiceprint recognition can be performed on each voice segment to determine which voice segment is the target subject's voice. Voiceprint recognition refers to identifying the speaker by analyzing the unique characteristics of each voice segment (similar to the uniqueness of a fingerprint). The voiceprint recognition process may include: analyzing each separated voice segment, extracting its characteristics using a voiceprint recognition model, and comparing it with an existing voiceprint database to confirm whether these voice segments belong to the target subject.

[0091] In some embodiments, the processing unit is configured to filter out other sound parts of the collected sound except the sound part of the target object to obtain the sound part of the target object.

[0092] Here, a method for extracting the sound of a target object is provided. Noise suppression technology can be used to remove environmental noise to improve the sound clarity of the target object, for example, Wiener filtering technology, DNS (Deep Noise Suppression) technology, etc.

[0093] In this way, by performing noise filtering on the collected sound, the clarity of the target object's sound is improved, so that a clearer target object's sound can be provided to the receiver.

[0094] The disclosed embodiments provide an electronic device that can be used in conference scenarios, video call scenarios, game scenarios, home theater scenarios, etc., and automatically adjusts the sound output according to different situations (such as switching of output modes, movement of target object positions, etc.), without the need for users to manually adjust settings, thereby improving ease of use. Moreover, the audio effect is optimized according to specific needs to improve the overall auditory effect. Whether in meetings, calls, games or entertainment, good sound effect optimization can help users hear the other party's voice more clearly, thereby improving the user experience.

[0096] Among them, the Hub acts as a hub or connector, responsible for aggregating, distributing or connecting multiple signal sources or devices. The Scaler is an image scaler, which is used to convert image resolution. The image acquisition unit can adopt an ISP (Image Signal Processor), which can use a camera to capture images. The processing unit can adopt a DSP (Digital Signal Processor), which is connected to the sound output unit. The sound output unit has Mic1 and Mic2 (i.e., sound output module). Of course, Mic1 and Mic2 can also be integrated with a sound acquisition unit.
