Referring to fig. 1-2, the head-mounted display device with a sound cavity structure of a temple according to the present embodiment includes a frame (not shown), a temple 10, a speaker 2, and a speaker cover 3; the temples 10 are respectively connected to both sides of the glasses frame, and the temples 10 include a temple inner casing 1 and a temple outer casing 4 which are installed in a matched manner. When the head-mounted display device of the embodiment is worn, the temple inner shell 1 is located at a position close to the face of a person, and the temple outer shell 4 is located at a position far away from the face of the person.

Referring to fig. 3-6, a first cavity 11 with an opening facing the temple outer housing 4 is formed in the temple inner housing 1, and a speaker mounting groove 12 is formed in the first cavity 11. The first cavity 11 is provided to mainly improve the low-frequency sound quality of the speaker 2, and the head-mounted display device of the embodiment makes full use of the inner space of the temple inner casing 1 to form the first cavity 11.

The temple inner shell 1 is further provided with a sound outlet hole 13, and the sound outlet hole 13 is communicated to the horn mounting groove 12. Preferably, in order to achieve a good sound transmission effect, the sound outlet hole 13 is shaped like a bar and faces the human ear.

The horn 2 is arranged in the horn mounting groove 12, sound emitted by the horn 2 is transmitted to the outside through the sound emitting hole 13, and the horn cover 3 is connected with the opening of the first cavity 11 in a matched manner; the cooperation of the horn cover 3 and the first cavity 11 surrounds the resonant cavity of the horn 2, so as to enhance the bass effect of the sound generated by the horn 2.

It can be understood that when the speaker 2 is operated, the sound emitted from the speaker 2 resonates in the resonant cavity, and then is emitted after passing through the sound emitting hole 13 after enhancing the bass effect. The head-mounted display equipment with mirror leg sound cavity structure of this embodiment has set up the sound cavity structure on the mirror leg ingeniously, has fully utilized 1 inner space of mirror leg inner shell, has realized the reinforcing of sound bass effect under the condition that does not use other external member, and the head-mounted display equipment of this embodiment realizes the lightweight structure easily.

In addition, the first cavity 11 may be formed by the whole temple inner casing 1, the cross section of the temple inner casing 1 presents a U shape with one end opened, specifically, both the front and rear ends of the temple inner casing 1 are provided with partitions 17 protruding towards the temple outer casing 4, and the temple inner casing 1 and the two partitions 17 together enclose the first cavity 11. The horn cover 3 is mutually matched and connected with the temple inner shell 1 and the two partition plates 17 to enclose a resonant cavity forming the horn 2. Through this kind of mode of setting, can separate first cavity 11 in mirror leg inner shell 1 and form loudspeaker 2's resonant cavity, optimized mirror leg inner shell 1 inside usage space for can also set up other cavities in mirror leg inner shell 1, can also let the installation of loudspeaker lid 3 and first cavity 11 more stable. Specifically, the number of the partition plates 17 is two in the present embodiment, and the two partition plates 17 are disposed opposite to each other.

Preferably, in order to make the sound emitted by the horn 2 more effective, the horn 2 of the present embodiment includes a sound emitting end 21 and a non-sound emitting end 23; the sound outlet end 21 of the horn 2 faces the bottom wall of the horn mounting groove 12 and is spaced from the bottom wall of the horn mounting groove 12, and the sound outlet hole 13 is communicated to a space between the sound outlet end 21 of the horn 2 and the bottom wall of the horn mounting groove 12.

The sound outlet end 21 of the speaker 2, that is, the end of the speaker 2 that makes sound, in this embodiment, the sound outlet end 21 of the speaker 2 is the end of the speaker 2 on which the diaphragm is disposed, and the speaker 2 of this embodiment may be 0815 of the speaker 2. Because loudspeaker 2's vibrating diaphragm is through the vibration sound production, need provide the space for vibrating diaphragm vibrate, consequently this loudspeaker 2 goes out sound end 21 need be spaced apart in the diapire of loudspeaker mounting groove 12. The non-sound-emitting end 23 of the speaker 2, i.e. the position of the speaker 2 except the sound-emitting end 21, for example, the non-sound-emitting end 23 of the speaker 2 of this embodiment is a supporting structure located at the edge of the diaphragm of the speaker 2, and also faces the bottom wall of the speaker mounting groove 12.

Further, the distance between the sound outlet end 21 of the horn 2 and the bottom wall of the horn mounting groove 12 is at least 0.5 mm. The vibrating diaphragm of loudspeaker 2 of this embodiment can release the distance that is close to 0.5mm at the vibration in-process, and the play sound end 21 of loudspeaker 2 is 0.5mm at least with the interval distance of the diapire of loudspeaker mounting groove 12, can guarantee loudspeaker 2's normal work.

Preferably, an air release hole 31 is formed in the horn cover 3 or the temple inner shell 1, and the air release hole 31 is communicated with the first cavity 11. The air release hole 31 is used for balancing the internal and external air pressures of the first cavity 11, so that the vibrating diaphragm of the loudspeaker 2 is prevented from bulging or shrinking due to unequal front and back air pressures, and the effects of improving the sound effect and protecting the loudspeaker 2 are achieved. In this embodiment, the air release hole 31 is opened in the horn cover 3.

Further, a supporting portion 14 for supporting the horn 2 extends from the bottom wall of the horn mounting groove 12, wherein the supporting portion 14 is in contact with a non-sound-emitting end 23 of the horn 2. In the present embodiment, the supporting portion 14 supports the horn 2 to be spaced from the bottom wall of the horn installation groove 12, and in some other embodiments, the effect of spacing the horn 2 from the bottom wall of the horn installation groove 12 can be achieved by other structures. The support portion may be a bone support portion designed to fit the non-sound-emitting end 23 of the speaker 2.

Further, division board 17 is last to be provided with row line hole 15, thereby the winding displacement can pass row line hole 15 and connect loudspeaker 2, sets up row line hole 15 and can conveniently arrange in order the winding displacement. Specifically, a bus bar hole 15 is provided on the divider 17 near the frame, and a bus bar extends from the frame to the temple through the bus bar hole 15.

Furthermore, a positioning column 33 is arranged on the horn cover 3, a positioning groove 16 is arranged in the first cavity 11, and the positioning column 33 is inserted into the positioning groove 16. Through the arrangement, when the horn cover 3 is installed, the opening of the first cavity 11 can be accurately covered by the horn cover 3, and the installation difficulty is reduced.
