The first volume adjusting instruction in the embodiment of the application may be a volume adjusting instruction for increasing the volume value by a preset value, may also be a volume adjusting instruction for decreasing the volume value by a preset value, and may also be a volume adjusting instruction for adjusting the volume value to a specified volume value. For example: when a user operates a volume plus key on the remote controller, the remote controller sends a first volume adjusting instruction for increasing the volume value by 1 to the display device, and correspondingly, the display device receives the first volume adjusting instruction for increasing the volume value by 1 sent by the remote controller. For another example: when the user receives a voice input of "adjust volume value to 8" through the voice receiving component on the remote controller, the remote controller sends a first volume adjusting instruction for adjusting the volume value to 8 to the display device, and correspondingly, the display device receives the first volume adjusting instruction for adjusting the volume value to 8 sent by the remote controller.

And S72, adjusting the volume of the display equipment according to the first volume adjusting instruction.

For example, when the first volume adjustment instruction is a volume adjustment instruction for increasing the volume value by 1 and the current volume value of the display device is 5, adjusting the volume of the display device according to the first volume adjustment instruction includes: and increasing the volume value of the display device by 1 by executing the first volume adjusting instruction, so that the volume value of the display device is adjusted to 6.

For example, when the first volume adjustment instruction is a volume adjustment instruction for adjusting the volume value to 8 and the current volume value of the display device is 5, adjusting the volume of the display device according to the first volume adjustment instruction includes: and adjusting the volume value of the display device from 5 to 8 by executing the first volume adjusting instruction.

It should be further noted that, in the LE Audio technical specification, the hearing aid protocol defines a hearing aid remote controller role of the hearing aid, and the hearing aid remote controller may transmit control signals such as volume adjustment to the hearing aid and be executed by the hearing aid, so that only when the hearing aid supports the hearing aid service, the display device may transmit volume adjustment information to the hearing aid as the hearing aid remote controller role and be executed by the hearing aid, and therefore, in the case that it is determined that a bluetooth connection is established with the hearing aid supporting the hearing aid service, the subsequent steps may be executed to adjust the volume of the hearing aid.

In step S73, if the display device does not establish a bluetooth connection with the hearing aid supporting the hearing aid service, the volume adjustment method according to the embodiment of the present application is terminated, and the volume of the display is adjusted only according to the received volume adjustment command, and if the display device establishes a bluetooth connection with the hearing aid supporting the hearing aid service, the following step S74 is executed:

and S74, acquiring a first volume value and a second volume value.

The first volume value is the volume value of the display device after the volume of the display device is adjusted according to the first volume adjusting instruction, and the second volume value is the volume value of the hearing aid.

In some embodiments, the display device obtains the second volume value (volume value of the hearing aid) by: and the display equipment sends volume request information to the hearing aid through the Bluetooth connection, receives volume response information returned by the hearing aid through the Bluetooth connection, and analyzes the volume response information to acquire the second volume value.

In some embodiments, the display device obtains the second volume value (volume value of the hearing aid) by: the display device maintains the hearing aid Volume value in a Volume Control Protocol (VCP) module and reads the second Volume value from the VCP module.

And S75, determining whether a hearing aid volume adjusting condition is met according to the first volume value and the second volume value.

I.e. determining whether the first and second volume values fulfil a condition for adjusting the volume of the hearing aid.

In step S75, if it is determined that the hearing aid volume adjustment condition is not satisfied according to the first volume value and the second volume value, the volume adjustment method according to the embodiment of the present application is ended, and if it is determined that the hearing aid volume adjustment condition is satisfied according to the first volume value and the second volume value, the following step S76 is executed:

And S77, generating a second volume adjusting instruction according to the loudness of the ambient sound.

In some embodiments, the second volume adjustment instruction may be a volume adjustment instruction for increasing or decreasing a volume value by a preset value. For example: the second volume adjustment instruction may be a volume adjustment instruction for increasing the volume value by 1.

In some embodiments, the second volume adjustment instruction may be a volume adjustment instruction for adjusting the volume value to a specified volume value. For example: the second volume adjustment instruction may be a volume adjustment instruction for adjusting the volume value to 8.

And S78, sending the second volume adjusting instruction to the hearing aid through the Bluetooth connection so as to adjust the volume of the hearing aid.

In some implementations, the display device further encapsulates the second volume adjustment instruction based on a bluetooth communication protocol between the display device and the hearing aid prior to sending the second volume adjustment instruction to the hearing aid over the bluetooth connection.
