The present embodiment provides a glasses leg Q with a speaker support, please refer to fig. 1 and 2, which includes a housing 10 and a speaker 11 disposed inside the housing 10. The horn 11 is disposed within the housing 10 by means of a bracket 12. A partition is formed between the bracket 12 and the inner wall of the housing 10, so that a front sound cavity 13 corresponding to the sound outlet end of the loudspeaker 11 and a rear sound cavity 14 corresponding to the rear end of the loudspeaker 11 are mutually partitioned.

Preferably, referring to fig. 2, the outer periphery of the horn 11 is sealed from the inner wall of the casing 10, and the front sound cavity 13 is better isolated from the rear sound cavity 14. More preferably, a sealing layer 103 is formed by filling glue or soft material between the outer periphery of the horn 11 and the inner wall of the housing 10. The sealing layer 103 provides a buffer between the horn 11 and the housing 10, so that the housing 10 and the horn 11 are prevented from resonating when the horn 11 operates.

Wherein the support 12 is of an annular configuration. The horn 11 is fixed inside the ring structure. The contact position of the bracket 12 and the loudspeaker 11 is surface contact, so that the sealing performance is improved, and the loudspeaker 11 is fixed more firmly.

Referring to fig. 2, a cavity 15 is formed inside the housing 10. The bracket 12 is fixed in the cavity 15, and the horn 11 is also placed in the cavity 15.

Preferably, the cavity 15 includes a cylindrical cavity 151 and a tapered cavity 152. The holder 12 is disposed at the junction of the tapered cavity 152 and the cylindrical cavity 151 to secure the holder 12. The rear end of the horn 11 is disposed within the conical cavity 152 such that a rear sound cavity 14 is formed between the inner wall of the conical cavity 152 and the rear end of the horn 11.

Referring to fig. 2, the rear sound cavity 14 has a plurality of sound outlet holes 141, so that when the speaker 11 works, the rear end of the speaker 11 vibrates, and the rear sound cavity 14 is ventilated through the sound outlet holes 141. The sound outlet holes 141 are provided in plural, five in this embodiment, so that the output of medium and high frequency sound is increased, and the outdoor experience is enhanced.

Referring to fig. 2, 4 and 5, the front end of the speaker 11 and the inner wall of the housing 10 form the front sound cavity 13. The front sound cavity 13 is provided with a sound outlet 131. When the user wears the temple, the sound outlet 131 is located at the front side of the ear and near the ear hole.

Specifically, referring to fig. 1 and 2, the housing 10 includes an upper shell 101 and a lower shell 102. The recess 15 is provided in the lower case 102. The speaker 11 is mounted in the cavity 15 of the lower shell 102 so that the rear end of the speaker 11 and the inner wall of the lower shell 102 form the rear sound cavity 14.

The front sound cavity 13 is formed among the front end of the loudspeaker 11, the inner wall of the lower shell 102 and the inner wall of the upper shell 101. The front sound cavity 13 is provided with a sound outlet 131, and the sound outlet 131 is arranged on one side of the lower shell 102.

Referring to fig. 2 and 3, an installation angle a is formed between the upper casing 101 and the sound outlet end surface of the speaker 11, so that the sound emitted from the speaker 11 is reflected by the upper casing 101 and then transmitted from the sound outlet 131, thereby improving the reflection of the middle-high frequency band and outputting the sound through the sound outlet 131. 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 11 is laterally arranged in the glasses legs, and the sound outlet end faces the head of the human body. The sound outlet 131 is provided at the lower edge of the housing 10 so that the sound outlet 131 can face the ear hole when worn.

Referring to fig. 1 and 2, the casing 10 further includes an extending portion 16, and the extending portion 16 is an arc-shaped structure and extends to the rear side of the ear.

Preferably, referring to fig. 1, 2 and 4, the housing 11 is located at the sound outlet 131 and is provided with a bulge 17 facing the sound outlet 131. The bulge 17 is an arc-shaped structure, and the sound outlet 131 is arranged on the arc-shaped structure so that the sound outlet 131 is also an arc-shaped hole. When the user wears the temple, the ridge 17 can be extended as far as possible to the ear hole, so that the sound of the speaker 11 is directionally propagated to the ear. At the same time, the provision of the extension 17 enables the cavity 15 in which the horn 11 is mounted to be as large as possible, thus enabling the mounting of a more powerful horn 11.

Referring to fig. 1, 2 and 4, the casing 10 is further provided with an auxiliary sound chamber 18 communicating with the rear sound chamber 14. The auxiliary sound chamber 18 is provided below the battery and at the lower edge of the housing 10. The auxiliary sound cavity 18 is provided with a sound outlet auxiliary hole 181 at the lower edge of the casing 10. In use, a part of sound of the speaker 11 can be transmitted through the elongated auxiliary sound cavity 18 and then transmitted out from the auxiliary sound outlet 181, so as to form a sound field in front of the ear and form a surround sound with the sound outlet 131, thereby increasing the surround sound effect. Moreover, the elongated auxiliary acoustic cavity 18 is advantageous for absorbing noise of a specific wavelength at the rear end of the horn 11. In addition, the sound outlet hole 141 at the rear end of the speaker 11 is added to form a sound field at the periphery of the user's ear, so that the anti-interference is enhanced and the effect of directional sound is increased.

Specifically, the front sound cavity 13 and the rear sound cavity 14 do not interfere with each other inside the casing 10. Most of sound at the sound outlet end of the loudspeaker 11 passes through the front sound cavity 13 and then is transmitted to the ear hole from the sound outlet 131, and a main sound field is formed at the ear hole; a part of the sound at the rear end of the speaker 11 is transmitted through the sound outlet hole 141, and an external sound field is formed outside the ear; another part of the sound of the rear end of the speaker 11 is propagated from the sound-emitting auxiliary hole to the front side of the ear through the sound-emitting auxiliary hole 181, 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 sound outlet hole 141 at the rear end of the horn 11 forms an included angle of 80 to 90 degrees with the sound outlet 131 of the front sound cavity 13. Generally, the sound transmitted through the sound outlet hole 141 and the sound outlet 131 has an interference effect in a certain distance range outside the ear, the forward and backward sound waves can cancel each other, the sound is prevented from leaking, the interference to the surrounding people is reduced, and the sound superposition effect is provided at a close distance of the ear hole, so that the sound is directionally reinforced.

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.

Compared with the prior art, the utility model has the advantages that the loudspeaker 11 is connected with the shell 10 of the glasses leg through the bracket 12, and the sealing layer 103 is arranged between the loudspeaker 11 and the shell 10, so that the front sound cavity 13 and the rear sound cavity 14 are mutually isolated and do not interfere with each other, resonance is reduced, the sound is more pure, the sound effect is better, and the installation is convenient; the interaction between the sound outlet 131 of the front sound cavity 13 and the sound outlet 141 of the rear sound cavity 14 can cancel each other out the sound of the forward and reverse sound waves within a certain distance range, thereby reducing the leakage of the sound.
