[0020] As used herein, references to orientation and direction are made with respect to a typical wearing position of the audio glasses device. Terms such as ‘upper’ , ‘lower’ , ‘side’ , and ‘vertical’ relate to how the audio glasses device and its components would be positioned during normal wearing. Thus, these directional terms are referenced in relation to the orientation or direction of the audio glasses device when it is worn as intended.
[0021] The present disclosure provides an audio glasses device. The audio glasses device comprises a speaker unit located within the glasses temple. Additionally, the audio glasses device includes an acoustic venting chamber located in the glasses temple and in communication with a rear space behind a diaphragm of the speaker unit, wherein the acoustic venting chamber comprises a first acoustic venting hole and a second acoustic venting hole communicating the acoustic venting chamber to atmosphere outside the audio glasses device, with the first acoustic venting hole being positioned higher than the second acoustic venting hole. In one or more embodiments, the first acoustic venting hole is vertically aligned with the second acoustic venting hole.
[0022] By this configuration, when the audio glasses device encounters water exposure, such as rain, water may enter the acoustic venting chamber through the first acoustic venting hole and then exit through the second acoustic venting hole, preventing water accumulation within the acoustic venting chamber, resulting in improved waterproofing for the audio glasses device.

[0026] This design, which incorporates the PCB chamber into the rear acoustic volume of the speaker unit, efficiently utilizes the free space in the PCB chamber, and maximizes the rear acoustic volume of the speaker unit, allowing for an improved audio performance of speaker unit, especially in low frequency range.
[0027] Fig. 1A illustrates a perspective view of an audio glasses device 100 according to one or more embodiments of the present disclosure. Fig. 1B is a perspective view similar to Fig. 1A, with an outer portion of the housing of one of the glasses temples 130 being removed to reveal inner structures of the glasses temple 130. The audio glasses device 100 comprises a glasses frame 110 and two glasses temples 130. The glasses frame 110 comprises a frame body and two endpieces 112, either fixedly connected to or integral with the frame body. Each glasses temple 130 is pivotally connected to a respective endpiece 112 of the glasses frame 110 via a hinge 120. Each glasses temple 130 comprises a speaker unit 142 for producing an audio output, a PCB 152 having electric elements mounted thereon and configured to generate an electric audio signal for driving the speaker unit 142, and a battery 192 configured to supply power to the electric elements. Each glasses temple 130 is also formed with a speaker chamber 140 containing the speaker unit 142, a PCB chamber 150 containing the PCB 152 and the electric elements thereon, an acoustic venting chamber 160, and a battery chamber 190 containing the battery 192. In the embodiments shown, the two glasses temples 130 are symmetrically arranged or configured, and thus the description provided in relation to one glasses temple can also be applied to the other glasses temple. FIG. 2A is a partially enlarged view of FIG. 1B, showing the internal structures of the glasses temple 130. FIG. 2B is a view similar to FIG. 2A, with the PCB 152 removed from the PCB chamber 150 to reveal the structures of the PCB chamber 150.
[0028] Figs. 3A-3B illustrate enlarged perspective views of a glasses temple 130 of the audio glasses device 100, with an outer portion of the housing of the glasses temples 130 removed to reveal its inner structure. In Fig. 3A, glasses temple 130 is shown with a fabric mesh 170 removed to reveal the inner structure of the acoustic venting chamber 160 while in Fig. 3B, the glasses temple 130 is shown with the fabric mesh 170 attached. As shown, the glasses temple 130 is also formed with an audio output chamber 146 that is located adjacent to the speaker chamber 140 and in communication with a front space in front of a diaphragm (not shown in Figs. 3A-3B) of the speaker unit 142. An audio outlet 146a is formed in the audio output chamber 146, allowing sound to be transmitted from the audio output chamber 146 to outside of the audio glasses device 100. During operation, the sound generated by the speaker unit 142 emits from the audio glasses device 100 through the audio outlet 146a.
[0029] The glasses temple 130 is also formed with an acoustic venting chamber 160 which is located adjacent to the audio output chamber 146, such that the audio output chamber 146 is located between the speaker chamber 140 and the acoustic venting chamber 160. The acoustic venting chamber 160 is defined by walls of the glasses temple 130, and the fabric mesh 170 located within the glasses temple 130. The acoustic venting chamber 160 is in communication with a rear space behind the diaphragm (not shown in Figs. 3A-3B) of the speaker unit 142 through the fabric mesh 170. The acoustic venting chamber 160 also comprises a first acoustic venting hole 162 and a second acoustic venting hole 164. The first acoustic venting hole 162 and the second acoustic venting hole 164, allow communication from the acoustic venting chamber 160 to the external atmosphere outside audio glasses device 100. This configuration provides a compact structure that efficiently channels the sound generated by the speaker unit 142 out of the audio glasses device 100, while effectively providing a pressure equilibrium in the rear space behind the diaphragm of the speaker unit 142.
[0030] Fig. 4A illustrates another perspective view of an audio glasses device 100 according to one or more embodiments of the present disclosure. Fig. 4B is an enlarged section view taken along line 4B-4B of Fig. 4A, passing through the acoustic venting chamber 160 to reveal its internal structures. As shown in Fig. 4B, a fabric mesh 170 is provided within the glasses temple 130. The fabric mesh 170 is vertically oriented, dividing an inner space of the glasses temple 130 into the acoustic venting chamber 160 and a space 172. The space 172 is in communication with the rear space behind the diaphragm (not shown in Figs. 4A-4B) of the speaker unit 142. The acoustic venting chamber 160 is defined by walls of the glasses temple 130 and the fabric mesh 170. Specifically, the acoustic venting chamber 160 is defined by an upper wall 160a, a lower wall 160b, a sidewall 160c of the glasses temple 130, and the fabric mesh 170. The acoustic venting chamber 160 further comprises a first acoustic venting hole 162 provided in the upper wall 160a, and a second acoustic venting hole 164 provided in the lower wall 160b. The first acoustic venting hole 162 is positioned directly above, and thus in a vertical alignment with the second acoustic venting hole 164.
[0031] During use, the audio glasses device 100 may encounter water exposure, such as rain. In this situation, water may enter the acoustic venting chamber 160 through the first acoustic venting hole 162 in the upper wall 160a and then exit through the second acoustic venting hole 164 in the lower wall 160b, preventing water accumulation within the acoustic venting chamber 160. The fabric mesh 170 allows gas flow or communication between the acoustic venting chamber 160 and the space 172 while concurrently acting as a barrier against water penetration into the space 172. In one or more embodiments, the fabric mesh 170 is treated with a hydrophobic coating to improve the waterproof capacity of the audio glasses device. This configuration allows the rear space behind the diaphragm of the speaker unit 142 to communicate, and thus maintain pressure equilibrium with the external environment through acoustic venting holes 162 and 164, thereby improving sound performance, especially in a low frequency range. Furthermore, the presence of acoustic venting holes 162 and 164 ensures that no water is accumulated within the acoustic venting chamber 160. This further ensures that any water or moisture entering the acoustic venting chamber 160 does not penetrate through the fabric mesh 170 into the space 172. This is crucial in preventing water or moisture from reaching the rear space behind the diaphragm of the speaker unit 142, which could otherwise impact the internal components of the speaker unit. Such a design guarantees the audio performance of the speaker, particularly the bass response, while simultaneously ensuring the waterproof of the audio glasses device 100.
[0032] In the embodiment shown in Fig. 4B, a vertically oriented fabric mesh 170 is provided, facilitating gas communication between the acoustic venting chamber 160 and the space behind the diaphragm of the speaker unit 142, while preventing water or moisture from penetrating through the mesh 170 into space behind the diaphragm of the speaker unit 142. In one or more other embodiments, the fabric mesh 170 may have a different shape, structure, or orientation as long as it allows gas communication between the acoustic venting chamber 160 and the space behind the diaphragm of the speaker unit 142 while preventing water or moisture from penetrating through the mesh 170. In one or more still other embodiments, the mesh 170 may be any suitable type other than a fabric mesh, and may not necessarily include a hydrophobic coating, as long as it can prevent water from penetrating, on the premise that there is no water accumulation in the acoustic venting chamber 160. In one or more still other embodiments, instead of the fabric mesh 170, the acoustic venting chamber 160 may be provided with another means that allows gas communication between the acoustic venting chamber 160 and the space behind the diaphragm of the speaker unit 142 while preventing water or moisture from penetrating therethrough into space behind the diaphragm of the speaker unit 142.
[0033] In the embodiment shown in Fig. 4B, one first acoustic venting hole 162 is provided in the upper wall 160a and one second acoustic venting hole 164 is provided in the lower wall 160b, with the first acoustic venting hole 162 being in a vertical alignment with the second acoustic venting hole 164. In one or more other embodiments, the first acoustic venting hole 162 and the second acoustic venting hole 164 may not be vertically aligned. In yet another set of embodiments, the first acoustic venting hole 162 and the second acoustic venting hole 164 may not be positioned in the upper and lower walls, respectively. For example, at least one of the first acoustic venting hole 162 and the second acoustic venting hole 164 may be located in the sidewall 160c, as long as the first acoustic venting hole 162 is positioned higher than the second acoustic venting hole 164 to allow water to enter through the first acoustic venting hole and exit through the second acoustic venting hole, preventing accumulation within the acoustic venting chamber 160.
[0034] Fig. 5A illustrates a sectional view of an audio glasses device 100 according to one or more embodiments of the present disclosure. Fig. 5B is an enlarged view of area 5B in Fig. 5A. As shown in Fig. 5B, the speaker unit 142, which is housed within the speaker chamber 140, comprises a speaker frame 142a and a diaphragm 142b affixed to the speaker frame 142a. The speaker unit 142 also comprises a magnetic assembly (not shown) attached to the speaker frame 142a and a voice coil (not shown) attached to the diaphragm 142b. The space or area behind the diaphragm 142b is designated as a rear space 144a and the space or area in front of the diaphragm 142b is designated as a front space 144b. The audio output chamber 146 is located adjacent to the speaker chamber 140 and in communication with the front space 144b. The audio outlet 146a formed in the audio output chamber 146 allows sound to be transmitted from the audio output chamber 146 to outside of the audio glasses device 100. A spacer plate 180 is provided within the glasses temple 130. The spacer plate 180 not only partially defines a boundary of the audio output chamber 146 but also serves as a separation and / or isolation mechanism between the audio output chamber 146 and the rear space 144a. During operation, the diaphragm 142b vibrates in response to an electric audio signal transmitted to the speaker unit 142. The sound generated by the diaphragm 142b travels to the front space 144b, following a path indicated by the dotted arrow 148, into the audio output chamber 146, and then emitted from the audio glasses device 100 through the audio outlet 146a.
[0035] The acoustic venting chamber 160 and the space 172 are in communicating with the rear space 144a behind the diaphragm 142b of the speaker unit 142. Consequently, the rear space 144a, the space 172, and the acoustic venting chamber 160 may collectively contribute to the rear acoustic volume of the speaker unit 142. In one or more embodiments, the rear space 144a is also in communication with the PCB chamber 150 (shown in Figs. 2A-2B) . In the embodiments, the rear space 144a, the space 172, the PCB chamber 150, and the acoustic venting chamber 160 may collectively contribute to the rear acoustic volume of the speaker unit 142. This design, which incorporates acoustic venting chamber 160, the space 172, and / or the PCB chamber 150 into the rear acoustic volume of the speaker unit 142, efficiently utilizes the internal space of the glasses temple 130, such as the free space in the PCB chamber 150, and maximizes the rear acoustic volume of the speaker unit 142. This allows for increased air movement and vibration, and thus significantly enhances the audio performance of speaker unit 142, especially in low frequency range.
[0036] In the embodiments shown, the two glasses temples 130 are symmetrically arranged or configured and both of the glasses temples 130 are formed with a speaker unit 142 and thus can generate an audio output. In one or more other embodiments, only one of the glasses temples 130 is provided with a speaker unit and can generate an audio output.
