The present embodiment does not impose any limitation on this.
Correspondingly, the specific air pressure value of the preset air pressure 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 can also be the air pressure value configured by the user, so that the use experience of the wearer is improved; for example, after wearing the head-mounted display device, the wearer can send out an air pressure configuration instruction to enable the head-mounted display device to control the expansion adjusting component to inflate the inner cavity of the flexible material wall; after the air inflation reaches the state that the bone conduction microphone on the flexible material wall is tightly attached to the head of the wearer, the wearer can send out a configuration completion instruction, the head-mounted display device is controlled to determine the air pressure acquired by the current air pressure sensor as the preset air pressure and store the air pressure, or the head-mounted display device can automatically generate the configuration completion instruction after detecting the state that the bone conduction microphone is tightly attached to the head of the wearer, and the air pressure acquired by the current air pressure sensor is determined as the preset air pressure and store the air pressure. That is, the method provided by the present embodiment may further include: when the wearing condition is detected to be in a wearing state, the telescopic adjusting component is controlled to inflate the inner cavity of the flexible material wall according to the acquired air pressure configuration instruction; and determining the air pressure acquired by the current air pressure sensor as preset air pressure according to the acquired configuration completion instruction and storing the preset air pressure.
Step 103: a sound signal emitted by a wearer of the head mounted display device captured by a bone conduction microphone on the flexible material wall is received.
It can be understood that after the flexible material wall stretches out to preset position, the processor in this step can receive the sound signal that the head-mounted display equipment's that bone conduction microphone gathered sent to can utilize the accurate sound signal that the bone conduction microphone of laminating wearer's head gathered to carry out subsequent voice control operation, promote voice control's accuracy.
Correspondingly, the processor in this embodiment 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.
