In order to facilitate further understanding of the technical solution in the embodiments of the present application, the following describes in detail each step of the method for adjusting the sound effect in the display device with reference to some embodiments and the accompanying drawings.

S110, acquiring an adjusting instruction for outputting an audio signal.

Various types of application programs can be installed in the display device for users to experience functions which are not used, such as video call, karaoke, entertainment, learning and the like, and for the application needing to adjust the output audio signals, the adjustment instruction can be obtained through monitoring the application programs, and the adjustment instruction can be obtained through triggering the application programs in use by the users.

It should be understood that the user may trigger the generation of the adjustment instruction for outputting the audio signal by opening the application, clicking a corresponding control with audio output function at the interface of the application, etc. For example, when the user opens the karaoke application, or after the user opens the karaoke application, by clicking the "record karaoke" control, the generation of an adjustment instruction for outputting an audio signal may be triggered; for another example, the user opens a learning application with a read-following link, and when the display device plays the read-following content, the user triggers generation of an adjustment instruction for outputting the audio signal.

Obviously, the user can trigger generation of the adjusting instruction for outputting the audio signal in other interaction modes; for example, when the display device is connected to an external device related to sound effect adjustment, generation of an adjustment instruction for outputting an audio signal may also be triggered.

And S120, responding to the adjusting instruction, and acquiring stable data and adjustable data.

The stable data comprise model data and chip data of the display device, and the adjustable data comprise power amplifier type data, microphone type data and loudspeaker type data in the display device or an external device.

It should be understood that the power amplifier type data, the microphone type data, and the speaker type data in the tunable data may be determined based on hardware parameters of the display device itself, or may be determined based on an external device connected to the display device. The external device may include an external microphone, an external speaker, and the like.

In some embodiments, the display device is already connected to the external device before the adjustment instruction for outputting the audio signal is received in step 110, at which time, in response to the adjustment instruction, it may be determined by the external device that some or all of the data of the adjustable data is acquired.

For example, in a state where the display device is externally connected to the microphone, the adjustable data obtained after the steps 110 and 120 are: the power amplifier type data and the speaker type data are determined by hardware parameters of the display device, and the microphone type data are determined by an external microphone connected to the display device.

In response to the adjustment instruction, stable data are obtained from system data of the display device, and taking intelligent electricity as an example, the device model of each intelligent television and the chip with sound effect adjustment are data determined when the device leaves the factory, namely the stable data in the embodiment of the application.

In some embodiments, the model data of the display device may also be replaced by serial data of the display device, etc., and the specific application may depend on: whether the hardware-related configuration of the display device is distinguished by the series of display devices or by the model of the display device.

For some series or low-model display devices only provided with a main control chip, or display devices with performance requirements capable of realizing sound effect adjustment through the main control chip, at this time, the chip data in the embodiment of the application comprise relevant data of the main control chip.

For some series or model high, or good performance display devices, besides the main control chip, there may be an independent sound effect adjusting chip, where the chip data in the embodiment of the present application includes related data of the main control chip and related data of the sound effect adjusting chip.

Meanwhile, in response to the adjustment instruction, adjustable data are obtained from system data of the display device or data of external devices, and the display device is provided with hardware devices related to sound effects, such as a power amplifier (called power amplifier for short), a loudspeaker, a microphone and the like, but the external devices can be connected with the display device through an external device interface of the display device, and the external devices can replace the hardware devices in the display device to realize corresponding functions.

It should be understood that the corresponding power amplifier type data, microphone type data, and speaker type data in the adjustable data may be adjusted accordingly as the usage of the display device changes.

When the external device is an external microphone, updating microphone type data; when the external equipment is an external loudspeaker, updating microphone type data; when the external device comprises an external microphone and an external loudspeaker, the microphone type data and the microphone type data are updated.

On the premise that the display device is not connected with the external device, the external device is monitored to be connected, fig. 6 shows a flow chart of sound effect adjustment when the external device is an external microphone in the embodiment of the application, and fig. 7 shows a flow chart of sound effect adjustment when the external device is an external microphone and external speaker in the embodiment of the application.

As shown in fig. 6, in the case that the display device is connected to the external microphone, the microphone type data in the adjustable data will be converted from the microphone type data of the system itself to the external microphone type data; as shown in fig. 7, in the case where the display device connects the external microphone and the external speaker, the microphone type data in the adjustable data will be converted from the microphone type data of the system itself to the external microphone type data, and the speaker type data in the adjustable data will be converted from the speaker type data of the system itself to the external speaker type data.

It should be noted that the data type of each of the corresponding data in the stable data and the adjustable data is determined in connection with the application case of the embodiment of the present application and the performance of each device itself, for example, the microphone type data in the adjustable data is decibel data (db) corresponding to each type of microphone.

For the storage of the adjustable data, for example, the model data of the microphone may be stored directly in the form of a database, a data list, or the like, or the model data may be used as a standard, and the difference data between the model data and the standard may be stored.

For example, the microphone type data corresponding to the microphone of the display device is B, and a certain external microphone type data is a, where B is standard data, a is difference data +2db relative to B, and after the display device is connected to the external microphone, the microphone type data in the adjustable data is adjusted to a by B.

As shown in fig. 4, S130, based on the stability data, the matched sound effect configuration data is screened out from the sound effect parameter configuration library.

For different display devices, the best matching sound effect configuration data may be determined by searching a sound effect parameter configuration library. In the matching process, searching and matching can be performed through all stable data, if corresponding data exist at the moment, the data are used as the best matched sound effect configuration data, if no corresponding data exist at the moment, the priority of the stable data is ordered, searching and matching are performed by taking single stable data with high priority as a reference, and if no matching data are searched at the moment, one piece of warranty data is provided.

When the stable data comprise model data and chip data of the display equipment, if first data matched with the stable data exist in the sound effect parameter configuration library, determining the first data as sound effect configuration data; if the first data matched with the stable data does not exist in the sound effect parameter configuration library, and the second data matched with the chip data exists in the sound effect parameter configuration library, determining that the second data is sound effect configuration data; and if the first data which is completely matched with the stable data does not exist in the sound effect parameter configuration library and the second data which is matched with the chip data does not exist in the sound effect parameter configuration library, determining that the bottom protection data in the sound effect parameter configuration library is sound effect configuration data.

The sound effect parameter configuration library includes each stable data list, and priority of each stable data, and corresponding sound effect parameter data, and when the stable data includes model data and chip data of the display device, table 1 is specific contents of the sound effect parameter configuration library in some embodiments, and may include the following contents:

And combining the sound effect configuration data and the adjustable data, determining a corresponding sound effect compensation strategy, performing first sound effect adjustment on the audio signal to be output according to the sound effect compensation strategy, and outputting the adjusted sound effect data to a loudspeaker in the display device or a loudspeaker in the external device.

For example, the standard data of the microphone type data is B, if the sound effect gain of the other microphone type data is a= +2db, c= -1db, the standard data of the power amplifier type data is a digital power amplifier, and if the standard data is an analog power amplifier, the gain of the relevant power amplifier type data is +8db; standard data of speaker type data class O, if the sound effect gain of other speaker type data is class P, the attenuation is-3 db, and if it is class Q, the gain is +5db.

If the obtained adjustable data of the display device is an analog power amplifier, the type of a loudspeaker is Q type, and the external microphone for a user is A, gains of sound adjustment corresponding to the current audio signal are needed, including microphone gain (+2db), analog power amplifier (+8db) and microphone gain (+5db), when the sound effect processing is carried out, data corresponding to a corresponding sound effect compensation strategy are determined based on the matched sound effect configuration data and gain data +15db, and first sound effect adjustment is carried out on the output audio signal based on the second time.
