Preferably, the installation included angle a is 1 to 20 °, in this embodiment, the installation included angle a is 6.5 °, the sound-emitting directional effect is better, and the experience is better in an outdoor noisy environment. Wherein, the loudspeaker 12 is laterally arranged in the glasses legs, and the sound outlet end faces the head of the human body. Sound outlet hole 103 is provided at the lower edge of case 10 so that sound outlet hole 103 faces the ear hole when worn.

Preferably, referring to fig. 1 and 3, the housing 11 is located at the sound outlet 103, and a protrusion 17 is disposed toward the sound outlet direction of the sound outlet 103. The bulge 17 is an arc-shaped structure, and the sound outlet hole 103 is arranged on the arc-shaped structure, so that the sound outlet hole 103 is also an arc-shaped hole. When the user wears the temple, the ridge 17 extends as far as possible into the ear opening, so that the sound of the speaker 12 is directed to the ear. At the same time, the provision of the extension 17 enables the cavity 23 in which the horn 12 is mounted to be as large as possible, thus enabling the mounting of a more powerful horn 12.

Referring to fig. 1, the casing 10 further has an auxiliary chamber 106 communicating with the rear sound chamber 104. The auxiliary chamber 106 is provided below the battery and at the lower edge of the case 10. The auxiliary cavity 106 is provided with a sound outlet auxiliary hole 1061 at the lower edge of the housing 10, and when in use, a part of sound at the rear end of the speaker 12 can be transmitted through the elongated auxiliary cavity 106 and then transmitted out from the sound outlet auxiliary hole 1061, so as to form a sound field in front of the ear and form surround sound with the sound outlet hole 103, thereby increasing the surround sound effect. Moreover, the elongated auxiliary cavity 106 is advantageous for absorbing noise of a specific wavelength at the rear end of the horn 12. In addition, the air inlet 105 at the rear end of the loudspeaker 12 is added to form a sound field at the periphery of the ear of the user, so that the interference resistance is enhanced, and the effect of directional sound is increased.

Specifically, the front sound cavity 102 and the rear sound cavity 104 do not interfere with each other inside the housing 10, most of the sound at the sound outlet end of the speaker 12 passes through the front sound cavity 102 and then is transmitted from the sound outlet hole 103 to the ear hole, and a main sound field is formed at the ear hole; a part of the sound at the rear end of the loudspeaker 12 is transmitted through the air inlet hole 105, and an external sound field is formed outside the ear; another part of the sound at the rear end of the speaker 12 is propagated from the auxiliary sound outlet hole to the front side of the ear through the auxiliary chamber 106, and forms a front sound field at the front side of the ear. The external sound field, the front sound field and the main sound field interact to form a surround sound effect.

Wherein, the sound outlet direction of the air inlet 105 at the rear end of the horn 12 forms an included angle of 80 degrees to 90 degrees with the sound outlet hole 103 of the front sound cavity 102. Generally, the sound transmitted through the air inlet hole 105 and the sound outlet hole 103 has an interference effect within a certain distance range outside the ear, forward and backward sound waves can cancel each other out, so that the sound is prevented from leaking, the interference to surrounding people is reduced, and the sound superposition effect is realized at a close distance of the ear hole, so that the sound is directionally reinforced.

Most of open audio glasses on the market at present cause sound to be dispersed all around due to design defects such as cavity structure design, loudspeaker placement angle design and sound outlet hole position design, the sound is exposed more to interfere surrounding people, and tone quality performance is insufficient. The arrangement of the front sound cavity 102, the rear sound cavity 104, the auxiliary cavity 106 and other structures of the invention can achieve better sound quality performance, enhance the sound near the auditory canal and reduce the sound exposure in a certain distance range away from the auditory canal.

Referring to fig. 1 and 6, an audio glasses includes the above-mentioned glasses leg Q, and a glasses frame Q1 hinged to the glasses leg Q. The two glasses legs Q are symmetrically arranged at the two ends of the glasses frame Q1.
