[0074] The voice input structure 4 is connected at a position away from the body 200 through the first mounting bracket 2, and the voice output structure 5 is connected at a position away from the body 200 through the second mounting bracket 3, so as to protect the voice input structure 4 and the voice output structure 5, avoid the influence of the heat emitted by the body 200 of the electric heater on the voice control component such as the voice input structure 4 and the voice output structure 5, and ensure the temperature resistance of the voice input structure 4 and the voice output structure 5; the voice input structure 4 and the voice output structure 5 can be installed separately through the first mounting bracket 2 and the second mounting bracket 3, and are spaced apart, so as to reduce the cross-talk between the voice input structure 4 and the voice output structure 5 and simultaneously meet the EMC (electromagnetic compatibility) test requirements.

[0075] Specifically, in an embodiment, the voice input structure 4 can be a microphone, and the voice output structure 5 can be a loudspeaker. The voice input structure 4 is used for receiving the voice information of the user and transmitting the voice information to the mainboard 9.

[0079] The voice input structure 4 and the first limiting ribs 22 are limited and abut against each other, which realizes the interference fit between the voice input structure 4 and the first mounting groove 21, ensures the stable mounting of the voice input structure 4 in the first mounting groove 21, and avoids the tilting or falling of the voice input structure 4. In addition, the first limiting ribs 22 extending along the slot depth direction of the first mounting groove 21 can also guide the mounting of the voice input structure 4, reduce the contact area between the voice input structure 4 and the first mounting groove 21, and reduce friction and noise. Further, through the arrangement of the first limiting ribs 22, the face contact between the voice input structure 4 and the slot wall of the first mounting groove 21 can be avoided, and the influence of the production error of at least one of the voice input structure 4 and the first mounting groove 21 on the assembly therebetween can be avoided.

[0080] In a specific embodiment, the shape of the first mounting groove 21 matches the shape of the voice input structure 4.

[0081] In a further embodiment, the voice input structure 4 includes a voice input body and an input housing, the voice input body is arranged in the input housing, the input housing is a closed housing, the front end of the input housing is provided with a sound input hole, and after the voice input structure 4 is connected to the first mounting groove 21, the front end of the input housing is located at the slot opening of the first mounting groove 21.

[0084] In a specific embodiment, the wire slot 23 has at least two, and the at least two wire slots 23 are spaced apart around the circumference of the first mounting groove 21, preferably uniformly distributed. The groove wall of the first mounting groove 21 is divided into at least three groove sections by the wire slot 23, and at least one first limiting rib 22 is arranged on each groove section.

[0085] In a further embodiment, the wire slot 23 extends from the groove opening of the first mounting groove 21 to the groove bottom.

[0086] In one embodiment, the voice input structure 4 protrudes from the groove opening of the first mounting groove 21.

[0087] The face cover 1 includes a first cover wall 11 away from the fuselage 200, and the voice input structure 4 protrudes from the groove opening of the first mounting groove 21. During the installation of the first mounting bracket 2 and the face cover 1, when the first mounting bracket 2 abuts against the first cover wall 11, the voice input structure 4 can be ensured to abut against the first cover wall 11 first.

[0088] In a further embodiment, the distance D of the voice input structure 4 protruding from the groove opening of the first mounting groove 21 satisfies 2mm≤D≤3mm. The distance D is small, and the voice input structure 4 can be prevented from being separated or falling off from the first mounting groove 21, and the voice input structure 4 can abut against the first cover wall 11 first during the installation of the first mounting bracket 2 and the face cover 1.

[0089] In a specific embodiment, the distance D of the voice input structure 4 protruding from the groove opening of the first mounting groove 21 can be 2mm, 3mm, or 2.5mm.

[0090] In one embodiment, the face cover 1 includes a first cover wall 11 and a second cover wall 12, and the two sides of the first cover wall 11 are connected to the fuselage 200 through two second cover walls 12 respectively.

[0094] The first mounting bracket 2 is connected to the tilt switch bracket 6, and the voice input structure 4 is connected to the mask 1 through the tilt switch bracket 6. This simplifies the connection of the first mounting bracket 2 and allows for direct connection using the existing tilt switch bracket 6 on the front shell device 100, avoiding modifications to the front shell device 100 and reducing the number of parts.

[0095] Specifically, the tilt switch is a switch structure that controls the power cut-off of the entire machine when it is tilted, serving a protective function. The tilt switch was initially installed on the tilt switch bracket 6 for power-off protection when the machine is tilted. However, due to the inconspicuous effect of the tilt switch, the structure was adjusted so that the tilt switch was installed on the base 20, ensuring that the tilt switch's action is noticeable when the prototype is slightly tilted. The original tilt switch bracket 6 does not need to be disassembled and can be directly used to install the first mounting bracket 2. The screw holes 61 on the tilt bracket switch, originally used for installing the tilt switch, can now be used to install the first mounting bracket 2.

[0096] In one embodiment, the front housing device 100 further includes a first fixing strip 7, which is connected between one side of the first mounting bracket 2 and the tilt switch bracket 6.

[0097] By setting the first fixing strip 7, the first mounting bracket 2 can be extended on the side of the first mounting bracket 2 facing the body 200, so as to ensure that the first mounting bracket 2 can be connected to the tilt switch bracket 6 through the first fixing strip 7, thereby increasing the distance between the voice input structure 4 and the body 200, further preventing the heat emitted by the body 200 from affecting the voice input structure 4, and ensuring that the voice input structure 4 and the first cover wall 11 of the mask 1 away from the body 200 can be closely attached to ensure the corresponding sound reception effect is accurate.
