The flexible wall 10 in this embodiment may be made of a flexible material (e.g., silicone), so that the flexible wall 10 can change in shape such as expanding, and contracting with the thrust of the telescopic adjusting member 30. The flexible material wall 10 in this embodiment may be disposed on an inner wall of the head-mounted display device, i.e. a side wall facing the wearer, so that when the flexible material wall 10 extends outward, the bone conduction microphone 20 on the flexible material wall can be pushed to move toward the head of the wearer, so that the bone conduction microphone 20 fits the head of the wearer.
Specifically, the specific telescopic manner of the flexible material wall 10 in the embodiment, that is, the specific manner in which the telescopic adjusting component 30 pushes the flexible material wall 10, can be set by a designer according to a practical scenario and a user requirement, for example, the telescopic adjusting component 30 can inflate and deflate the internal cavity of the flexible material wall 10 to adjust the air pressure of the internal cavity, so as to correspondingly push the flexible material wall 10 to extend or retract outwards; that is to say, the flexible material wall 10 may form an internal cavity by itself or with the inner wall of the head-mounted display device, so that the telescopic adjusting component 30 can adjust the position of the bone conduction microphone 20 on the flexible material wall 10 by inflating and deflating the internal cavity of the flexible material wall 10, thereby enabling the bone conduction microphone 20 on the flexible material wall 10 to move and tilt along with the air pressure change of the internal cavity, and the internal cavity of the flexible material wall 10 forms a physical shock absorption effect, and improves the fitting effect of the bone conduction microphone 20 and the wearer, thereby improving the experience for use. The telescopic adjusting member 30 can also push the flexible material wall 10 to extend or retract outwards by a motor and a push rod, which is not limited in this embodiment.

The wall 10 of flexible material may also be provided on an inner wall of a frame member of the eyewear equipment, such as at a nose pad location of the frame member; the embodiment is not limited as long as the flexible material wall 10 is ensured to be disposed on the inner wall facing the wearer so that the bone conduction microphone 20 on the flexible material wall 10 can contact the head position of the wearer with the extension of the flexible material wall 10.
It should be noted that the telescopic adjustment member 30 in the present embodiment may be a member for pushing the flexible material wall 10 to extend or retract outwardly. As for the specific structure of the telescopic adjusting component 30, it can be set by the designer according to the practical scene and the user's requirement, for example, when the telescopic adjusting component 30 is specifically used for inflating and deflating the internal cavity of the flexible material wall 10, as shown in fig. 2, the telescopic adjusting component 30 may include an air pump pipe 31 and a micro air pump 32; wherein, the first end of the air pump pipeline 31 is connected to the internal cavity, and the second end of the air pump pipeline 31 is connected with the micro air pump; the micro air pump 32 is used for inflating and deflating the internal cavity through the air pump pipeline 31 according to the control of the processor 40, so that the flexible material wall 10 can stretch and expand along with the change of air pressure, and the position of the bone conduction microphone 20 on the flexible material wall 10 can be correspondingly adjusted. The telescopic adjustment member 30 may also include a motor and a push rod; wherein, the first end of the push rod is connected with the flexible material wall 10, and the second end of the push rod is connected with the motor; the motor is used for pushing the flexible material wall 10 to extend or retract through the pushing rod according to the control of the processor 40.

Wherein, the processor 40 (such as the AP main chip) in this embodiment can control the pushing force of the telescopic adjusting component 30 to the flexible material wall 10 to adjust the position of the bone conduction microphone 20; for example, the processor 40 can control a micro air pump in the telescopic adjusting component 30 to inflate and deflate the internal cavity of the flexible material wall 10, so as to adjust the air pressure of the internal cavity, and the position of the bone conduction microphone 20 can be adjusted through the air pressure adjustment. Correspondingly, the processor 40 may also receive the sound signal collected by the bone conduction microphone 20, so as to implement the subsequent voice control operation.

The present embodiment does not set any limit to this.
Correspondingly, the specific setting of the preset air pressure value can be set by a designer or a user according to a practical scene and user requirements, for example, the preset air pressure can be a preset fixed air pressure value; the preset air pressure value can also be configured by a user, so that the use experience of a wearer is improved; for example, a wearer can send an air pressure configuration instruction after wearing the head-mounted display device, so that the head-mounted display device controls the telescopic adjusting component to inflate the inner cavity of the flexible material wall; when the air is inflated to a state that the bone conduction microphone on the flexible material wall is tightly attached to the head of the wearer, the wearer can send a configuration completion instruction, the head-mounted display device is controlled to determine the air pressure collected by the current air pressure sensor to be preset air pressure and store the preset air pressure, or the head-mounted display device can automatically generate the configuration completion instruction after the state that the bone conduction microphone is tightly attached to the head of the wearer is detected, and the air pressure collected by the current air pressure sensor is determined to be the preset air pressure and store the preset air pressure. That is, the method provided by this embodiment may further include: when the wearing condition is detected to be a wearing state, controlling the telescopic adjusting component to inflate the inner cavity of the flexible material wall according to the acquired air pressure configuration instruction; and determining the air pressure collected by the current air pressure sensor as the preset air pressure according to the obtained configuration completion instruction and storing the preset air pressure.
Step 103: sound signals emitted by a wearer of the head-mounted display device collected by bone conduction microphones on a wall of the flexible material are received.
It can be understood that, the sound signal that the person who wears display device that bone conduction microphone gathered is sent can be received to the treater in this step after flexible material wall stretches out to preset position to can utilize the accurate sound signal that the bone conduction microphone of laminating person's head gathered to carry out subsequent speech control operation, promote speech control's accuracy.
Correspondingly, in this embodiment, the processor may further control the flexible material wall on the inner wall of the head-mounted display device or on the bone conduction device to retract to the initial position when the head-mounted display device is turned off.
In the embodiment of the invention, the flexible material wall on the inner wall of the head-mounted display device or on the bone conduction device is controlled to extend to the preset position, and the bone conduction microphone on the flexible material wall is adjusted to be attached to the position of a wearer by utilizing the arrangement of the flexible material wall and the telescopic adjusting component, so that the head shapes of different wearers are adapted, the bone conduction microphone can be ensured to be closely attached to the head or the bone of the ear position of the wearer, the bone conduction microphone can better collect sound signals transmitted by bones, the accuracy and precision of sound pickup of the bone conduction microphone are improved, and the user experience is improved.
