Description

Technical Field

[0001] The present application relates to the technical field of display devices, and in particular to a display device and a volume adjustment method. Background Art

[0002] With the rapid development of display devices, display devices have gradually become the core component of digital home audio-visual experience. The volume of display devices is a relatively sensitive audio-visual parameter for users. For users, appropriate volume and intelligent volume adjustment can greatly improve user experience.

[0003] There are many ways for display devices to produce sound. For example, the display device's built-in speakers or other sound-generating devices can all play audio. In the scenario where the display device is connected to multiple sound-generating devices, currently only the volume of one of the devices can be adjusted, and the effect of intelligent volume adjustment cannot be achieved. Summary of the invention

[0004] The present application provides a display device and a volume adjustment method to solve the problem that the volume adjustment of the display device in the prior art is not intelligent enough.

[0005] In a first aspect, some embodiments provide a display device, comprising: a display configured to display a user interface; a controller connected to the display, configured to: when a target object has selected a target sound device type, in response to a first volume adjustment instruction, determine a plurality of external sound devices connected to the display device and belonging to the target sound device type; the plurality of external sound devices include sound devices of different sub-device types; based on a first volume adjustment parameter indicated by the first volume adjustment instruction, adjust the volume of each external sound device respectively to obtain a first volume value of each external sound device.

[0006] Through the above display device, the target object, that is, the user, can pre-select the target sound device type. In this way, when the controller of the display device receives the first volume adjustment instruction, multiple external sound devices connected to the display device and belonging to the target sound device type can be determined. Therefore, based on the first volume adjustment parameter indicated by the volume adjustment instruction, the volume of each external sound device is adjusted respectively to obtain the first volume value of each external sound device. Since the multiple external sound devices include sound devices of different sub-device types, the above display device can realize the volume adjustment of multiple different types of external sound devices at the same time. On the one hand, it effectively improves the intelligence of the volume adjustment, and the user no longer needs to adjust the volume of the device one by one, which also improves the convenience of volume adjustment. On the other hand, the display device can also connect more sound devices, which is conducive to improving the richness of the sound of the display device.

[0007] In the second aspect, some embodiments further provide a volume adjustment method, which is applied to the display device provided in the first aspect, the display device comprising: a display and a controller, the method comprising: in a case where the target object has selected the target sound device type, in response to a first volume adjustment instruction, determining a plurality of external sound devices connected to the display device and belonging to the target sound device type; the plurality of external sound devices comprising sound devices of different sub-device types; based on a first volume adjustment parameter indicated by the first volume adjustment instruction, adjusting the volume of each external sound device respectively, to obtain a first volume value of each external sound device.

[0008] In the above volume adjustment method, the target object, that is, the user, can pre-select the target sound device type. In this way, when the controller of the display device receives the first volume adjustment instruction, multiple external sound devices connected to the display device and belonging to the target sound device type can be determined. Therefore, based on the first volume adjustment parameter indicated by the volume adjustment instruction, the volume of each external sound device is adjusted respectively to obtain the first volume value of each external sound device. Since the multiple external sound devices include sound devices of different sub-device types, the above display device can realize the volume adjustment of multiple different types of external sound devices at the same time. On the one hand, it effectively improves the intelligence of the volume adjustment, and the user no longer needs to adjust the volume of the device one by one, which also improves the convenience of volume adjustment. On the other hand, the display device can also connect more sound devices, which is conducive to improving the richness of the sound of the display device. BRIEF DESCRIPTION OF THE DRAWINGS

The display 260 is used to receive an image signal output from the controller 250 for display. For example, the display 260 can be used to display video content, image content, and components of a menu control interface and a user control UI interface.

[0038] In some embodiments, the communication device 220 is a component for communicating with an external device or server 400 according to various communication protocol types. The display device 200 may be provided with a plurality of communication devices 220 according to different supported communication modes. For example, when the display device 200 supports wireless network communication, the display device 200 may be provided with a communication device 220 including a WiFi function.

[0044] In some embodiments, the user input interface 280 may be used to receive instructions from a user.

[0045] Figure 3 Some embodiments of the present application provide Figure 1 The hardware configuration diagram of the control device in the figure. Figure 3 As shown, the control device 100 may include: a controller 110, a communication interface 130, a user input / output interface, a memory, and a power supply.

[0046] The control device 100 is configured to control the display device 200 , and can receive user input operation instructions, and convert the operation instructions into instructions that the display device 200 can recognize and respond to, playing the role of an interactive intermediary between the user and the display device 200 .

[0047] In some embodiments, the control device 100 may be a smart device, for example, the control device 100 may be installed with various applications for controlling the display device 200 according to user needs.

[0048] In some embodiments, Figure 1As shown, the mobile terminal 300 or other intelligent electronic devices can play a similar function as the control device 100 after installing the application for controlling the display device 200 .

[0049] The controller 110 includes a processor 112, a RAM 113, a ROM 114, a communication interface 130, and a communication bus. The controller 110 is used to control the operation and operation of the control device 100, as well as the communication and cooperation between the internal components and the external and internal data processing functions.

[0050] The communication interface 130 implements communication of control signals and data signals with the display device 200 under the control of the controller 110. The communication interface 130 may include at least one of other near field communication modules such as a WiFi chip 131, a Bluetooth module 132, and an NFC module 133.

[0051] The user input / output interface 140 , wherein the input interface includes at least one of other input interfaces such as a microphone 141 , a touch panel 142 , a sensor 143 , and a button 144 .

[0052] In some embodiments, the control device 100 includes at least one of a communication interface 130 and an input / output interface 140. The control device 100 is configured with a communication interface 130, such as a WiFi, Bluetooth, NFC or other module, and can encode the user input command through the WiFi protocol, Bluetooth protocol, or NFC protocol and send it to the display device 200.

[0053] The memory 190 is used to store various operating programs, data and applications for driving and controlling the control device 100 under the control of the controller. The memory 190 can store various control signal instructions input by the user.

[0054] The power supply 180 is used to provide operating power support for each component of the control device 100 under the control of the controller.

[0055] In order to perform user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program for managing and controlling hardware resources and software resources in the display device 200. The operating system may provide a user interface (control the display device), allow the user to interact with the display device 200, and support the running of various application programs.

[0056] It should be noted that the operating system may be a native operating system based on a specific operating platform, or a third-party operating system deeply customized based on a specific operating platform, or an independent operating system specially developed for the display device.

[0057] The operating system can be divided into different modules or layers according to the functions implemented.

[0058] like Figure 4 As shown, Figure 4 Some embodiments of the present application provide Figure 1 Schematic diagram of software configuration in the display device. In some embodiments, the system of the display device 200 can be divided into three layers, namely, application layer, middleware layer and hardware layer from top to bottom.

[0059] The application layer mainly includes commonly used applications on TV and application frameworks. Common applications are mainly applications developed based on browsers, such as HTML5 APPs and native APPs.

[0060] The Application Framework is a complete program model that has all the basic functions required by standard application software, such as file access, data exchange, etc., as well as the user interfaces of these functions (toolbars, status bars, menus, dialog boxes).

[0061] Native apps can support online or offline, message push or local resource access.

[0062] The middleware layer includes various TV protocols, multimedia protocols, system components and other middleware. Middleware can use the basic services (functions) provided by the system software to connect various parts of the application system or different applications on the network, and can achieve the purpose of resource sharing and function sharing.

[0063] The hardware layer mainly includes the hardware abstraction layer (HAL) interface, hardware and drivers. The HAL interface is a unified interface for all TV chips to connect, and the specific logic is implemented by each chip. Drivers mainly include: audio driver, display driver, Bluetooth driver, camera driver, WIFI driver, USB driver, HDMI driver, sensor driver (such as fingerprint sensor, temperature sensor, pressure sensor, etc.), and power driver.

[0064] It should be noted that the above example is only a simple division of the operating system functions and does not constitute a limitation on the specific operating system form of the display device 200 in the embodiment of the present application. Depending on factors such as the function of the display device and the type of operating system, the number of levels and specific level types contained in the operating system may be expressed in other forms.

[0065] In some embodiments, when using a display device to play media, synchronized sound output is required, and the media includes video, audio, TV programs, etc. The display device has a variety of sound output methods, including but not limited to the built-in speakers of the display device, wired connection devices (wired headphones, wired speakers, etc.), and Bluetooth connection devices (Bluetooth headphones, Bluetooth speakers, etc.). The built-in speaker refers to the system-built-in sound device of the display device, which enables the display device to produce sound itself. Both the wired connection device and the Bluetooth connection device are external sound devices of the display device. Users can adjust the volume of these sound devices by adjusting the volume button of the remote control or by voice control.

[0066] However, there are currently certain limitations on the sound of display devices, such as the inability to adjust the volume of multiple different types of external sound devices at the same time, such as Bluetooth headsets and Bluetooth speakers. Considering that in actual applications, there may be scenarios where multiple different types of external sound devices need to make sounds, taking Bluetooth headsets and Bluetooth speakers as an example, for example, a user is wearing a Bluetooth headset in the room, and the Bluetooth speaker is in the living room. In this scenario, both the user in the room and the user in the living room need to hear the sound of the display device, that is, both the Bluetooth headset and the Bluetooth speaker need to make sounds. For users, if the volume of Bluetooth headsets and Bluetooth speakers can be adjusted at the same time in this scenario, it is undoubtedly smarter and more convenient. Of course, multiple different types of sound devices are not limited to Bluetooth headsets and Bluetooth speakers, but can also be wired devices and Bluetooth devices such as wired headsets and Bluetooth headsets.

[0067] Based on this, in order to enable the display device to adjust the volume of multiple different types of external sound devices at the same time, an embodiment of the present invention provides a display device, and the user can pre-select the target sound device type that needs to be sounded, so that the volume of all external sound devices belonging to the target sound device type can be adjusted. The target sound device type can be a Bluetooth connection device and a non-Bluetooth connection device, or a specified sound device type. If the user selects a Bluetooth connection device, the volume of multiple sound devices connected to the display device via Bluetooth can be adjusted, including but not limited to Bluetooth headphones and Bluetooth speakers. If the user selects a non-Bluetooth connection device, the volume of multiple sound devices connected to the display device through other connection methods other than Bluetooth connection, such as wired connection, Wi-Fi direct connection, etc. can be adjusted, including but not limited to wired connection devices (wired headphones, wired speakers), Wi-Fi connection devices, etc. If the user selects a specified sound device type, the volume of multiple sound devices belonging to the specified sound device class can be adjusted. For example, if the specified sound device type is a headphone device type, the volume of all Bluetooth headphones and wired headphones can be adjusted. Of course, the designated sound device type can be set according to actual conditions, for example, it can also be set to a speaker device type, and the embodiment of the present invention does not limit this. In this way, on the one hand, the intelligence and convenience of volume adjustment are effectively improved. On the other hand, the display device can also be connected to more sound devices, which improves the richness of the sound of the display device.

[0068] In some embodiments, a display device is provided, the display device comprising:

[0069] The display is configured to display a user interface.

[0070] Among them, the user interface refers to the interface for the controller of the display device to interact with the user, including but not limited to elements such as menus, icons, buttons, etc. The user can interact with the display device through the user interface.

[0071] In some embodiments, the display may also be configured to display a sound device type selection page, which may be understood as a page for displaying multiple candidate sound device types. The user may select a target sound device type from multiple candidate sound device types through the sound device type selection page.

[0072] In some embodiments, the display may also be configured to display a volume bar. It should be noted that while the display device is capable of adjusting the volume of multiple different types of sound devices, it also supports adjusting the volume of a single sound device. The volume bar displayed when adjusting the volume of multiple sound devices may be different from the volume bar displayed when adjusting the volume of a single sound device. For example, the volume bar displayed when adjusting the volume of multiple sound devices may only display the volume adjustment icon, while the volume bar displayed when adjusting the volume of a single sound device may display the specific volume value.

[0073] A controller connected to the display is configured to: when a target object has selected a target sound device type, determine a plurality of external sound devices connected to the display device and belonging to the target sound device type in response to a first volume adjustment instruction; the plurality of external sound devices include sound devices of different sub-device types.

[0074] Among them, the target object may refer to the user. The target sound device type may refer to the type of sound device that needs to make sound, or the target object is the type of sound device that the user allows to make sound, including but not limited to Bluetooth connected devices, non-Bluetooth connected devices, and specified sound device types. It can be understood that the volume adjustment performed after the user selects the target sound device type is the volume adjustment for all external sound devices belonging to the target sound device type. Each sound device type can have multiple matching external sound devices. The external sound device refers to a sound device that is externally connected to the display device. Taking the Bluetooth connection device as an example, the Bluetooth connection device can be a Bluetooth headset, a Bluetooth speaker, or other sound devices that can be connected to the display device via Bluetooth.

[0075] The first volume adjustment instruction is a volume adjustment instruction that matches the target sound device type, or in other words, it is a volume adjustment instruction for all external sound devices belonging to the target sound device type. The external sound device is connected to the display device. The sub-device type refers to the device type of the external sound device itself. It can be understood that the target sound device type is a large category, and each external sound device belonging to the target sound device type also has its own device type. For example, taking a Bluetooth connection device as an example, the Bluetooth connection device includes a Bluetooth headset and a Bluetooth speaker. The sub-device type of a Bluetooth headset is a Bluetooth headset class, and the sub-device type of a Bluetooth speaker is a Bluetooth speaker class, and the two are not the same. It should be noted that this embodiment is also applicable to the volume adjustment of multiple external sound devices with the same sub-device type, such as multiple Bluetooth headsets.

[0076] Exemplarily, after the user has selected the target sound device type in advance through the sound device type selection page displayed on the display, if the controller receives the first volume adjustment command initiated by the user through the remote control or voice control, it can first query the device information of each candidate sound device connected to the display device, including but not limited to the device name, device address, device connection status, the sound device type to which the candidate sound device belongs, the sub-device type, the current device volume, that is, the current volume value of the candidate sound device, etc. Then, from these candidate sound devices, the sound devices whose sound device type is consistent with the target sound device type are screened out, and these sound devices are multiple external sound devices belonging to the target sound device type.

[0077] It is understandable that the type of the sound device and the target sound device can be consistent in type name or type identifier. For example, if the target sound device type is "Bluetooth connected device" and the sound device type of a candidate sound device is also "Bluetooth connected device", the two types are considered to have the same name. Or if the target sound device type is "Type A" and the sound device type of a candidate sound device is also "Type A", the two types are considered to have the same identifier.

[0078] Based on the first volume adjustment parameter indicated by the first volume adjustment instruction, the volume of each external sound-emitting device is adjusted respectively to obtain the first volume value of each external sound-emitting device.

[0079] Among them, the first volume adjustment parameter refers to the volume adjustment related parameter indicated by the first volume adjustment instruction, which can be a volume adjustment step or a volume adjustment value. Of course, in addition to the volume adjustment step or the volume adjustment value, the first volume adjustment parameter can also include other related parameters such as volume adjustment time, volume adjustment method such as remote control adjustment or voice control adjustment, etc. The volume adjustment step can refer to the smallest unit of volume adjustment (volume increase or volume decrease). For example, if the volume adjustment step is 5, then each time the volume is adjusted, the volume will increase or decrease in steps of 5, that is, 5 volume values ​​are increased or decreased each time. The volume step can be a fixed value, such as 5, 10, etc. The volume adjustment value is a specific volume value to be adjusted, such as 30, 40, 50, etc. The first volume value refers to the volume value of each external sound device after volume adjustment under the first volume adjustment instruction.

[0080] It is understandable that the first volume value of each external sound-emitting device may be the same or different. For example, if the user directly gives a voice instruction "adjust the volume to 30", the volume values ​​of all external sound-emitting devices of the target sound-emitting device type will be uniformly adjusted to 30. If the user presses the volume increase key of the remote control, such as the "+" key, assuming that the volume adjustment step is 5, all external sound-emitting devices of the target sound-emitting device type will increase the volume by 5 based on their current device volume. Currently, if the current device volume of all external sound-emitting devices is the same, the volume value after increasing or decreasing the volume adjustment step should also be the same. If the current device volume of all external sound-emitting devices is different, the volume value after increasing or decreasing the volume adjustment step should also be different.

[0081] Exemplarily, the controller may parse the first volume adjustment instruction to obtain the volume adjustment step or volume adjustment value indicated by the first volume adjustment instruction. Based on the volume adjustment step or volume adjustment value, the volume of all external sound devices belonging to the target sound device type is adjusted to obtain the volume value of each external sound device. Specifically, the controller may calculate the volume value to be adjusted for each external sound device based on the volume adjustment step or volume adjustment value, and if the volume value is within the range of volume values ​​allowed to be adjusted by the display device, the current device volume of the external sound device is adjusted to the volume value. If the volume value is not within the range of volume values ​​allowed to be adjusted by the display device, the current device volume of the external sound device is adjusted to the maximum volume value allowed to be adjusted by the display device.

[0082] In this embodiment, the target object, that is, the user, can pre-select the target sound device type. In this way, when the controller of the display device receives the first volume adjustment instruction, multiple external sound devices connected to the display device and belonging to the target sound device type can be determined. Therefore, based on the first volume adjustment parameter indicated by the volume adjustment instruction, the volume of each external sound device is adjusted respectively to obtain the first volume value of each external sound device. Since the multiple external sound devices include sound devices of different sub-device types, the above display device can realize the simultaneous volume adjustment of multiple different types of external sound devices. On the one hand, it effectively improves the intelligence of the volume adjustment, and the user no longer needs to adjust the volume of the device one by one, which also improves the convenience of volume adjustment. On the other hand, the display device can also connect more sound devices, which is conducive to improving the richness of the sound of the display device.

[0083] In some embodiments, in the process of determining a plurality of external sound emitting devices connected to the display device and belonging to the target sound emitting device type, the controller is further configured to:

[0084] In the case that the target sound-emitting device type is a Bluetooth connection device, it is determined that the multiple external sound-emitting devices are multiple sound-emitting devices connected to the display device via Bluetooth.

[0085] Exemplarily, in addition to screening multiple sound devices belonging to the target sound device type by determining whether the sound device type of each candidate sound device is consistent with the target sound device type, the controller can also screen by the connection method between each candidate sound device and the display device. In the case where the target sound device type is a Bluetooth connected device, the controller can obtain the connection method between each candidate sound device and the display device from the device information of each candidate sound device, and screen out the sound devices whose connection method is Bluetooth connection from each candidate sound device.

[0086] In the case that the target sound device type is a non-Bluetooth connection device, it is determined that the multiple external sound devices are multiple sound devices connected to the display device through other connection modes except the Bluetooth connection mode.

[0087] Among them, non-Bluetooth connection devices refer to sound-emitting devices that are connected to the display device through other connection methods other than Bluetooth connection. Other connection methods may include wired connection or Wi-Fi connection. Wired connection refers to connection with the display device through a physical cable, such as wired headphones, wired speakers, etc. Wi-Fi connection refers to connection with the display device through a Wi-Fi network.

[0088] Exemplarily, similar to Bluetooth-connected devices, when the target sound device type is a non-Bluetooth-connected device, the controller can obtain the connection method between each candidate sound device and the display device from the device information of each candidate sound device, and filter out sound devices with wired connection or Wi-Fi connection from each candidate sound device.

[0089] In the case where the target sound device type is a designated sound device type, the plurality of external sound devices are determined to be a plurality of sound devices connected to the display device and belonging to the designated sound device type.

[0090] The designated sound device type can be understood as a pre-designated sound type, such as a headphone device type, a speaker device type, etc. The designated sound device type is directional. For example, if the user selects the headphone device type, the volume of all headphone devices can be adjusted at the same time, including Bluetooth headphones and wired headphones.

[0091] Exemplarily, when the target sound device type is a specified sound device type, the controller can obtain the sound device type of each candidate sound device from the device information of each candidate sound device, and filter out the sound devices whose sound device type is the specified sound device type from the candidate sound devices.

[0092] Optionally, the controller may also filter out sound devices belonging to a specified sound device type based on the respective sub-device type of each candidate sound device. For example, taking the headphone device class as an example, the controller may obtain the respective sub-device type of each candidate sound device, and thus treat the candidate sound devices whose sub-device type is the headphone class or whose type name contains a headphone field as sound devices belonging to the headphone device class.

[0093] In this embodiment, the external sound device can be a sound device connected to the display device via Bluetooth, a sound device connected to the display device via a wired connection or a Wi-Fi connection, and a sound device belonging to a specified sound device type. In this way, the display device can adjust the volume of various types of sound devices, which not only improves the intelligence of volume adjustment, but also helps the display device to connect more external sound devices, thereby improving the richness of the sound of the display device.

[0094] In some embodiments, the controller is further configured to:

[0095] In the case where the first volume adjustment parameter includes a volume adjustment step length, the volume of each external sound emitting device is adjusted based on the volume adjustment step length to obtain a device volume value of each external sound emitting device, and the device volume value is used as the first volume value.

[0096] Among them, the device volume value refers to the volume value that the external sound device should be adjusted to. For the remote control, if the volume up button or the volume down button is pressed once, it can be considered that the volume adjustment step is increased or decreased once, and the final volume adjustment step can be determined based on the number of key presses. For example, if the volume up button is pressed once, assuming the volume adjustment step is 5, the current device volume needs to be increased by 5. If the volume up button is pressed twice, corresponding to two volume adjustment steps, the current device volume needs to be increased by 10. Similarly, if the volume down button is pressed once, the current device volume needs to be reduced by 5. If the volume down button is pressed twice, the current device volume needs to be reduced by 10.

[0097] For voice control, users can directly say "volume increase / decrease by one volume adjustment step" or "volume increase / decrease by two volume adjustment steps", and can also control the current device volume to increase / decrease by 5 or 10 volumes. Of course, users can also voice indicate specific volume adjustment steps, such as "volume increase 3", "volume decrease 2". In other words, in the scenario of voice control volume adjustment, the volume adjustment step can be dynamic.

[0098] Exemplarily, when the first volume adjustment parameter includes a volume adjustment step length, the controller calculates the volume value that each external sound device needs to be adjusted to, that is, the device volume value, based on the volume adjustment step length and the current volume value of each external sound device obtained. For example, if the volume adjustment step length is 5 and the current volume value of a certain external sound device is 10, then the volume value that needs to be adjusted should be 15 (when the volume is increased) or 5 (when the volume is decreased).

[0099] In the case where the first volume adjustment parameter includes a volume adjustment value, the volume values ​​of each external sound-emitting device are adjusted to the volume adjustment value, and the volume adjustment value is used as the first volume value.

[0100] Exemplarily, when the first volume adjustment parameter includes a volume adjustment value, the controller may adjust the volume value of each external sound device belonging to the target sound device type to the volume adjustment value. That is to say, at this time, the device volume value of each external sound device is the same. For example, if the volume adjustment value is 30, the volume value of each external sound device will be adjusted to 30, regardless of whether the current device volume value is greater than 30 or less than 30. As for the external sound device whose current device volume value is already 30, no adjustment will be made. In this scenario, the user can also feedback the first volume adjustment instruction including the specific volume adjustment value to the display device through a remote control or voice.

[0101] In some embodiments, volume adjustment based on the volume adjustment step and volume adjustment based on the volume adjustment value can be understood as two ways of volume adjustment, and these two ways can be configured in the controller of the display device at the same time, for example, the user can first trigger a volume adjustment instruction including a volume adjustment step, and the controller adjusts the volume based on the volume adjustment step, and then the user triggers a volume adjustment instruction including a volume adjustment value, and the controller adjusts the volume based on the volume adjustment value. Of course, this embodiment does not limit the triggering timing of the volume adjustment instruction including the volume adjustment step or the volume adjustment value.

[0102] In this embodiment, two volume adjustment methods are introduced, namely, volume adjustment based on the volume adjustment step and volume adjustment based on the volume adjustment value. Both volume adjustment methods can be pre-configured in the controller of the display device, which improves the richness of the volume adjustment methods of the display device and is conducive to users to adjust the volume more conveniently.

[0103] In some embodiments, the display is further configured to display candidate device identifications of each candidate sound-emitting device connected to the display device.

[0104] The candidate sound device refers to each external sound device connected to the display device, including the sound device corresponding to the target sound device type and the sound device other than the target sound device type. The candidate device identifier refers to the unique identifier of the candidate sound device, such as the device name, device model, device number, etc.

[0105] Exemplarily, for all external sound devices connected to the display device, that is, each candidate sound device, the display will display any one or more of the unique identifiers such as the device name, device model, and device number of each candidate sound device. The display method can be through a display control, such as a scrolling list display control. Of course, other types of display controls can also be used, as long as they can display the candidate device identifiers of each candidate sound device, and this embodiment does not limit this. In this way, the user can select a target device identifier from each candidate device identifier, and the sound device corresponding to the target device identifier is the sound device that the user wants to adjust the volume separately.

[0106] Therefore, the controller is further configured to: when the target object selects the target device identifier from the candidate device identifiers, determine a first sound-emitting device that matches the target device identifier from the candidate sound-emitting devices.

[0107] The target device identifier is the target object, that is, the device identifier selected by the user from among the candidate device identifiers. The first sound device is the sound device that matches the target device identifier.

[0108] Exemplarily, when the target object selects a target device identifier from each candidate device identifier, the controller can select a first sound device that matches the target device identifier from each candidate sound device based on the target device identifier as the sound device that needs to be adjusted individually. It can be understood that adjusting the volume individually means adjusting the volume of only the first sound device, and not adjusting the volume of other sound devices.

[0109] In response to a second volume adjustment instruction for the first sound emitting device, the volume of the first sound emitting device is adjusted based on a second volume adjustment parameter indicated by the second volume adjustment instruction to obtain a second volume value of the first sound emitting device.

[0110] Among them, the second volume adjustment instruction is a volume adjustment instruction for the first sound-emitting device, which is used to instruct the first sound-emitting device to adjust the volume. The second volume adjustment parameter refers to the volume adjustment related parameter indicated by the second volume adjustment instruction, which can be a volume adjustment step or a volume adjustment value. The meaning of the second volume adjustment parameter is the same as that of the first volume adjustment parameter, which is not repeated here. The second volume value refers to the volume value of the first sound-emitting device after the volume is adjusted under the second volume adjustment instruction.

[0111] Exemplarily, after the controller screens out the first sound device that matches the target device identifier selected by the target object, if it receives a volume adjustment instruction for the first sound device, it can parse the volume adjustment instruction to obtain the corresponding volume adjustment step or volume adjustment value. Thus, based on the volume adjustment step or volume adjustment value, the volume of the first sound device is adjusted to obtain the volume value of the first sound device. It can be understood that the process of adjusting the volume of the first sound device based on the second volume adjustment parameter is the same as the process of adjusting the volume of each external sound device based on the first volume adjustment parameter, which will not be repeated here.

[0112] In this embodiment, in addition to being able to adjust the volume of multiple different types of external sound devices, the display device also supports volume adjustment for a single external sound device, that is, the user can select the sound device to be adjusted, thereby adjusting the volume of the sound device separately. This fully meets the needs of users, thereby further improving the intelligence of volume adjustment.

[0113] In some embodiments, during the volume adjustment process, the controller is further configured to: obtain a target volume value; the target volume value is any one of a first volume value and a second volume value; the second volume value is the volume value obtained after the volume of the first sound device is adjusted; the first sound device is the sound device selected by the target object from various candidate sound devices connected to the display device; obtain the volume limit of the display device, and when the target volume value is greater than the volume limit, update the target volume value to the volume limit.

[0114] It can be understood that whether the volume of multiple external sound devices is adjusted or the volume of a single external sound device is adjusted, it is necessary to determine the volume value, that is, to determine whether the volume value to be adjusted is within the volume adjustment range allowed by the display device, or whether it is greater than the maximum volume value of the volume adjustment range. For example, if the volume adjustment range allowed by the display device is 0 to 100, then the maximum volume value is 100. The maximum volume value is used as a volume limit value to be compared with the target volume value, that is, the first volume value or the second volume value.

[0115] Exemplarily, when the target volume value is the first volume value, that is, when the controller adjusts the volume of multiple external sound devices, the controller will compare the first volume value of each external sound device with the volume limit of the display device. If the first volume value is greater than the volume limit, it means that the volume to be adjusted by the external sound device exceeds the volume adjustment range allowed by the display device. At this time, the first volume value is updated to the volume limit. For example, if the first volume value is 105 and the volume limit is 100, the first volume value is greater than the volume limit, then the first volume value is directly updated to 100, that is, the device volume of the external sound device is 100. If the first volume value is less than the volume limit, it means that the volume to be adjusted by the external sound device does not exceed the volume adjustment range allowed by the display device. At this time, the device volume of the external sound device is determined to be the first volume value. For example, if the first volume value is 30 and the volume limit is 100, the first volume value is less than the volume limit, then the device volume of the external sound device is determined to be 30.

[0116] Similarly, when the target volume value is the second volume value, that is, when the controller adjusts the volume of a single external sound device, namely the first sound device, the controller also needs to compare the second volume value of the first sound device with the volume limit of the display device. If the second volume value is greater than the volume limit, it means that the volume to be adjusted by the first sound device exceeds the volume adjustment range allowed by the display device. At this time, the second volume value is updated to the volume limit, and the device volume of the first sound device is the volume limit. If the second volume value is less than the volume limit, it means that the volume to be adjusted by the first sound device does not exceed the volume adjustment range allowed by the display device. At this time, the device volume of the first sound device is determined to be the second volume value.

[0117] In some embodiments, the volume limit is not limited to the maximum volume value of the volume adjustment range allowed by the display device, and it can also be determined according to actual scenarios.

[0118] In this embodiment, by comparing the first volume value or the second volume value with the volume limit of the display device, when the first volume value or the second volume value is greater than the volume limit, the first volume value or the second volume value is updated to the volume limit. On the one hand, it can avoid sound quality distortion, noise and broken sound caused by too high volume setting, thereby affecting the user's viewing experience. On the other hand, it can also avoid overheating of the sound device and damage to the diaphragm due to too high volume, thereby affecting the performance of the sound device and even causing the sound device to malfunction.

[0119] In some embodiments, the display is further configured to: in response to a first volume adjustment instruction, display a first volume bar including a volume adjustment icon; in response to a second volume adjustment instruction, display a second volume bar including a second volume value; the second volume adjustment instruction is a volume adjustment instruction for a first sound device selected by a target object from among various candidate sound devices connected to the display device; and the second volume value is the volume value after the volume of the first sound device is adjusted.

[0120] It should be noted that this embodiment takes into account that when the volume of multiple external sound devices is adjusted, if the volume bar corresponding to each external sound device is displayed, there will be too many volume bars on the user interface, affecting the user's perception and operation. Therefore, in this embodiment, corresponding volume bar display modes are set for two scenarios: adjusting the volume of multiple external sound devices and adjusting the volume of a single external sound device.

[0121] The volume adjustment icon may include a volume increase icon and a volume decrease icon, such as Figure 5 shown. Figure 5 A schematic diagram of a first volume bar is shown, which includes a volume adjustment icon "+" and a volume adjustment icon "-". The volume adjustment icon can respond to the first volume adjustment instruction. For example, when the volume is increased, the volume adjustment icon "+" can be highlighted, and when the volume is decreased, the volume adjustment icon "-" can be highlighted. Figure 6 A schematic diagram of a second volume bar is shown. The second volume bar is used to adjust the volume of a single external sound device, and can display the specific volume value of the single external sound device.

[0122] Optional, Figure 5 The speaker icon in the can also be changed according to the actual situation. For example, when adjusting the volume of a Bluetooth-connected device, the speaker icon can be changed to a Bluetooth icon. When adjusting the volume of a non-Bluetooth-connected device, the speaker icon can remain unchanged. When adjusting the volume of a specified sound-emitting device type, such as a headphone device, the speaker icon can be changed to a headphone icon. Of course, corresponding icons can also be formulated according to actual conditions and the triggering method of icon changes can be determined, which is not limited in this embodiment.

[0123] Exemplarily, in response to the first volume adjustment instruction, that is, the volume of multiple external sound devices belonging to the target sound device type is adjusted, and the display can display a first volume bar containing a volume adjustment icon, and the specific display form of the volume adjustment icon is not limited in this embodiment. In response to the second volume adjustment instruction, that is, the volume of the first external sound device selected by the target object is adjusted separately, and the display can display a volume bar containing a second volume value.

[0124] Optionally, when there are relatively few external sound devices, such as only two, the display device may also display the volume bars of the two external sound devices on the user interface, and the volume bars may include the volume values ​​of the two external sound devices. Figure 5 The first volume bar in the

[0125] In this embodiment, corresponding volume bar display modes are set for two scenarios, namely, volume adjustment for multiple external sound devices and volume adjustment for a single external sound device, so that the display of the volume bar can adapt to different volume adjustment scenarios, thereby improving the intelligence of the volume bar display and user experience.

[0126] In some embodiments, the controller is further configured to: when all external sound-emitting devices are disconnected from the display device, use the sound-emitting device type other than the target sound-emitting device type as the target sound-emitting device type; when there is at least one second sound-emitting device connected to the display device among each external sound-emitting device, control the second sound-emitting device to emit sound.

[0127] Among them, the second sound-emitting device refers to a sound-emitting device that is connected to the display device. It should be noted that in actual applications, there are situations where the external sound-emitting device is disconnected from the display device. At this time, if all external sound-emitting devices are disconnected from the display device, in order to ensure that the display device makes sound normally, it is necessary to change the target sound-emitting device type, that is, select a sound-emitting device type other than the target sound-emitting device type as the target sound-emitting device type, and the sound-emitting device of this sound-emitting device type will continue to make sound. If at least one of the external sound-emitting devices is still connected to the display device, that is, not all external sound-emitting devices are disconnected from the display device, then the sound-emitting device can continue to be controlled to make sound.

[0128] For example, for a scenario where an external sound device is disconnected, if all external sound devices are disconnected from the display device, the controller may determine a sound device type other than the target sound device type, and use the sound device type as the target sound device type, and the sound device corresponding to the sound device type makes a sound.

[0129] In some embodiments, when the controller uses the sound device type other than the target sound device type as the target sound device type, the controller is further configured to: determine whether the display device is connected to other sound devices other than the external sound devices. If so, obtain the sound device type to which the other sound device belongs, and use the sound device type as the target sound device type; if not, control the built-in speaker of the display device to make a sound.

[0130] Among them, other sound devices refer to external sound devices connected to the display device except for various external sound devices.

[0131] Exemplarily, when all external sound devices corresponding to the target sound device type are disconnected from the display device, the controller can further determine whether the display device is connected to an external sound device other than these external sound devices. If so, the sound device type to which the external sound device belongs can be directly used as the target sound device type, and the external sound device makes a sound. If not, it means that the display device does not have any external sound device at this time, and the built-in speaker of the display device is controlled to make a sound.

[0132] For example, assuming that the target sound device type is a non-Bluetooth connected device, if all sound devices connected to the display device via wired or Wi-Fi are disconnected from the display device, the controller further detects whether the display device has other external sound devices connected to it. Assuming that the display device is also connected to a Bluetooth speaker, the sound device type to which the Bluetooth speaker belongs, that is, the Bluetooth connected device, is used as the target sound device type, and the Bluetooth speaker is controlled to make sound. In this scenario, subsequent volume adjustments are all for the Bluetooth connected device. If the display device does not have other external sound devices connected to it, the built-in speaker of the display device is controlled to make sound.

[0133] If at least one sound device is still connected to the display device, that is, an external sound device belonging to the target sound device type is still connected to the display device, then the external sound device continues to be controlled to make sound. It can be understood that when there are only one external sound device left from multiple external sound devices, the volume bar can automatically change from the first volume bar to the second volume bar. Similarly, if there are still multiple external sound devices after the device is disconnected, the first volume bar remains unchanged.

[0134] In some embodiments, when a new external sound device is connected to the display device, the device information of the new external sound device is recorded. If the new external sound device belongs to the current target sound device type, the new external sound device is adjusted synchronously during the next volume adjustment. If the new external sound device does not belong to the current target sound device type, the target object needs to wait until the sound device type selected by the target object is the sound device type to which the new external sound device belongs before the volume of the new external sound device can be adjusted in the scenario of adjusting the volume of multiple external sound devices. Of course, the target object can also select the new external sound device for separate volume adjustment.

[0135] In this embodiment, in the scenario where the external sound device is disconnected, it is determined whether all external sound devices are disconnected. If all are disconnected, the target sound device type is changed, otherwise other external sound devices except the disconnected sound device are controlled to make sound, so that the normal sound of the display device can be ensured.

[0136] In some embodiments, the display is configured to display a sound emitting device type selection page, which includes a plurality of candidate sound emitting device types.

[0137] Among them, the sound device type selection page refers to the page used to select the sound device type. Candidate sound device types may include Bluetooth connected devices, non-Bluetooth connected devices, and specified sound device types. Of course, in actual applications, you can also add or modify candidate sound device types according to actual conditions, such as setting TV speaker (built-in speaker), ARC (Audio Return Channel), SPDIF (Sony / Philips DigitalInterface Format, digital audio output). Users can select the target sound device type from these candidate sound device types.

[0138] The controller is further configured to: in response to a sound device type selection instruction triggered by a target object on a sound device type selection page, determine a target sound device type matching the sound device type selection instruction from a plurality of candidate sound device types.

[0139] The sound device type selection instruction refers to a confirmation instruction for the target object to select the target sound device type in the sound device type selection page.

[0140] Exemplarily, the target object can select one or more sound device types from multiple candidate sound device types through the sound device type selection page and click a confirmation button or control (not shown in the figure). After the controller detects the confirmation instruction triggered by the target object, it can determine the target sound device type that matches the confirmation instruction from multiple candidate sound device types. In this way, when the target object adjusts the volume subsequently, the volume of all external sound devices belonging to the target sound device type can be adjusted simultaneously.

[0141] In this embodiment, the target object can select the target sound device type that is allowed to make sound from the multiple candidate sound device types displayed on the pre-set sound device type selection page, or the target sound device type that the target object wants to adjust the volume at the same time. In this way, when receiving the volume adjustment instruction, the controller can adjust the volume of all external sound devices belonging to the target sound device type at the same time, thereby improving the intelligence of volume adjustment.

[0142] In a specific embodiment, the display device includes a display and a controller. Figure 7 As shown, the display shows a sound device type selection page, which displays Bluetooth connected devices (Bluetooth Speaker), non-Bluetooth connected devices, and specified sound device types such as headphone device type (Headphone Only).

[0143] Figure 8 The following figure shows the interactive diagram of volume adjustment of Bluetooth connected devices. It can be seen that the target object (User) first sets the target sound device type, that is, Figure 7 The Sound UI in the user interface will first receive the target sound device type and send a command to modify the sound device type to the Soundservice in the controller, which will modify the sound device type, that is, change the current sound device type to the target sound device type selected by the target object.

[0144] Among them, Sound UI is the UI module in the front-end interface, which can be used to receive the sound device type selected by the user. Sound service is the sound service module in the controller, which can be used to modify the sound device type and manage other sound devices except Bluetooth connected devices. In addition, Volume UI can be understood as the UI module in the front-end interface used to monitor volume adjustment instructions, and bluetooth service is the module in the controller used to manage Bluetooth connected devices.

[0145] It can be understood that if the target object selects a Bluetooth connection device, the volume of all multiple sound devices connected to the display device via Bluetooth can be adjusted at the same time, such as Bluetooth headphones and Bluetooth speakers. If the target object selects a non-Bluetooth connection device, the volume of all multiple sound devices connected to the display device via a wired connection can be adjusted at the same time, such as wired headphones and wired speakers. Of course, the premise is that the wired headphones or wired speakers need to be plugged into the display device. If the target object selects a specified sound device type, that is, a headphone device class, the volume of all headphone devices can be adjusted at the same time, such as Bluetooth headphones and wired headphones.

[0146] In response to the first volume adjustment command initiated by the target object through the remote control or voice, Volume UI will first receive the first volume adjustment command and request the target sound device type from Sound service. Assuming that the target sound device type is a Bluetooth connected device, Volume UI further requests the device information of all Bluetooth devices from bluetooth service, such as the current device volume value of the Bluetooth device. Volume UI can calculate the volume value of each Bluetooth device, send the volume value to bluetooth service, and then bluetooth service changes the volume value of each Bluetooth device and returns it to Volume UI. At the same time, Volume UI can display a first volume bar containing volume adjustment icons such as VOL+ / -.

[0147] Fig. 9 The following diagram shows the volume adjustment interaction of headphone devices. Unlike Bluetooth-connected devices, VolumeUI will request the connection status of wired headphones from the Sound service. If the Sound service feedback shows that the device is connected to wired headphones, Volume UI can also calculate the volume value of the wired headphones. If the Sound service feedback shows that the device is not connected to wired headphones, Volume UI only calculates the volume value of all Bluetooth headphones.

[0148] Fig.10The interactive schematic diagram of the sound device type transformation is shown. Before setting the target sound device type, the sound device needs to be connected first. Taking the Bluetooth device as an example, the Bluetooth device initiates a connection request to the display device through the bluetooth UI (Bluetooth UI). The bluetooth UI can be understood as a UI module in the front-end interface used to receive Bluetooth connection requests. The bluetooth UI sends the request to the bluetooth service, and the bluetooth service searches and connects the Bluetooth device, and at the same time feedbacks the connected Bluetooth device to the bluetooth UI. At this time, if the target object does not select the sound device type as a Bluetooth connection device, the Volume UI will display the volume bar of the whole device, that is, the sound is currently emitted by the built-in speaker of the display device, and the volume bar of the whole device may include the overall volume value of the display device. When the target object sets the target sound device type to a Bluetooth connection device, the sound device type is modified, that is, it is modified to a Bluetooth connection device. And the corresponding volume bar is displayed according to the number of Bluetooth devices currently connected. That is, if there are multiple Bluetooth devices, the first volume bar is displayed. If there is only one Bluetooth device, the second volume bar is displayed.

[0149] The display device also supports volume adjustment for a single sound device. That is, the display will display the candidate device identifiers of each candidate sound device connected to the display device, such as the device name, by scrolling the list display control. Fig.11 As shown, Fig.11 The left side of the scroll list display control is the scroll list display control, and the right side is the specific volume value. The target object can slide the scroll list display control up and down to select a target device name from multiple candidate device names (sound device name 1, sound device name 2). The sound device corresponding to the target device name is the sound device that needs to have its volume adjusted separately.

[0150] In some embodiments, the volume adjustment instruction may include a volume adjustment parameter, i.e., a volume adjustment step or a volume adjustment value. The controller may adjust the volume of each external sound device based on the volume adjustment step. The volume value of each external sound device may also be adjusted to the volume adjustment value. During the adjustment process, it is necessary to determine whether the volume value of each external sound device to be adjusted is greater than the volume limit of the display device. If greater, the volume value is updated to the volume limit.

[0151] Fig.12The interactive diagram of the disconnection of an external sound device is shown. In the case that at least one of the external sound devices is still connected to the display device, the bluetooth service will notify the volume UI that a device is disconnected. It can be understood that if an external sound device that is not a Bluetooth connected device is disconnected, the sound service will notify the volume UI that a device is disconnected (not shown in the figure). The volume UI requests the device information of the disconnected device from the bluetooth service or sound service, and the bluetooth service or sound service returns the device information of the disconnected device to it. At this time, the sound device is controlled to make sound and adjust the volume. If there are multiple sound devices connected, the first volume bar is displayed, and if there is only one, the second volume bar is displayed. In the case that there is only one external sound device connected to the display device, if the external sound device is disconnected from the display device at this time, the sound device type needs to be updated. Specifically, if the external sound device is a Bluetooth connected device, the bluetooth service notifies the sound service to modify the sound device type. The sound service will detect whether the display device is connected to other sound devices besides the external sound device. If so, the sound device type of the other sound device is obtained and the sound device type is used as the target sound device type. If not, the built-in speaker of the display device is controlled to make sound. If the external sound device is not a Bluetooth connected device, the sound service can automatically modify the sound device type.

[0152] Fig.13 The interactive diagram of connecting a new sound device is shown. When a new external sound device is connected to the display device, the bluetooth service or sound service will notify the volume UI that a new sound device is connected. The volume UI will request device information from the bluetooth service or sound service, and the bluetooth service or sound service will return the device information of the new external sound device to the volume UI. The volume UI displays the first volume bar or the second volume bar according to the current number of external sound devices.

[0153] In this embodiment, through the above display device, the target object, that is, the user, can pre-select the target sound device type. In this way, when the controller of the display device receives the first volume adjustment instruction, multiple external sound devices connected to the display device and belonging to the target sound device type can be determined. Therefore, based on the first volume adjustment parameter indicated by the volume adjustment instruction, the volume of each external sound device is adjusted respectively to obtain the first volume value of each external sound device. Since the multiple external sound devices include sound devices of different sub-device types, the above display device can realize the simultaneous volume adjustment of multiple different types of external sound devices. On the one hand, it effectively improves the intelligence of the volume adjustment, and the user no longer needs to adjust the volume of the device one by one, which also improves the convenience of volume adjustment. On the other hand, the display device can also connect more sound devices, which is conducive to improving the richness of the sound of the display device.

[0154] In some embodiments, the present application further provides a volume adjustment method, which is applied to the above-mentioned display device. Fig.14 As shown, the volume adjustment method includes the following steps:
