The same reference numerals will be used to denote the same or similar elements in all drawings.

Implementation Method

[0016] Please refer to Figures 1, 2, and 3 together. Figure 1 is a perspective view of the multimedia auxiliary device in some embodiments of the present invention. Figure 2 is a schematic diagram of the multimedia auxiliary device and glasses assembled in some embodiments of the present invention. Figure 3 is a schematic diagram of Figure 2 from a side view. As shown in Figures 1, 2, and 3, the multimedia auxiliary device 10 includes a frame 102, an auxiliary display group 104, a speaker module 106, and a clamping member 108. The frame 102 has a first support 110 and two second supports (112, 113), which are respectively connected to two sides of the first support 110. The auxiliary display group 104 is fixed to one side of the first support 110. The auxiliary display group 104 includes a multimedia processing module 114 and a projection lens 116. The multimedia processing module 114 is used to generate an image signal and an audio signal according to a multimedia signal. The projection lens 116 is used to project the image signal. The speaker module 106 is fixed to one of the two second brackets (112, 113) for playing sound signals. The clamp 108 is fixed to one of the two second brackets (112, 113) and is located between the auxiliary display group 104 and the speaker module 106.

[0017] The frame 102 can be fixed to a pair of glasses 20 by clamping member 108, so that the auxiliary display group 104 and the speaker module 106 can be externally attached to a person's head (details to follow). When the frame 102 and glasses 20 are installed (as shown in Figure 3), the first bracket 110 is correspondingly disposed on one of the frames 202 of the glasses 20, and the two second brackets (112, 113) are correspondingly disposed on the two temples 204 of the glasses 20. In some embodiments, the first bracket 110 and the two brackets (112, 113) have a wire groove (not shown in the figure) inside, and when the multimedia processing module 114 and the speaker module 106 are connected by a connecting wire (not shown in the figure), the connecting wire can be buried in the wire groove. In some embodiments, the first bracket 110 and the two second brackets (112, 113) can be integrally formed. The two second brackets (112, 113) can also be detached from the first bracket 110.

[0018] The speaker module 106 is electrically connected to the multimedia processing module 114 to receive and play audio signals. As shown in FIG3, the speaker module 106 may be embedded in the second bracket 112 (or the second bracket 113) so that the speaker module 106 can play towards the user's ear (the speaker module 106 may be positioned near the user's ear). The speaker module 106 may be, for example, a voice coil speaker, ribbon speaker, electrostatic speaker, piezoelectric speaker, bone conduction transducer, cartilage conduction transducer, tragus vibration transducer, and / or any other suitable type or form of audio transducer.

[0019] The clamping member 108 can clamp onto the temple 204, allowing the multimedia assistive device 10 to be assembled onto the eyeglasses 20. In some embodiments, the clamping member 108 has two clamping plates (118, 119) with a gap 120 between them. The gap 120 has an assembly direction (as shown in the Z-axis direction in FIG3), and the clamping member 108 can be assembled onto the temple 204 according to the assembly direction of the gap 120 to fix the multimedia assistive device 10 onto the eyeglasses 20. In some embodiments, the two clamping plates (118, 119) are elastic, changing the size of the gap 120 through their own elasticity. For example, the size of the gap 120 may be equal to or less than the width of the temple 204. When the clamping member 108 contacts the temple 204, the temple 204 can open the gap 120 and embed itself therein. It should be noted that when the temple 204 is located in the gap 120, the gap 120 can squeeze the temple 204 to prevent the multimedia auxiliary device 10 from falling off the temple 204.

[0020] Please refer to Figures 1, 2, 3, and 4 together. Figure 4 is an exploded view of the auxiliary display group in some embodiments of the present invention. As shown in Figures 1, 2, 3, and 4, in some embodiments, the multimedia processing module 114 includes a housing 122, a processing circuit 124, a sound acquisition module 126, an image acquisition module 128, and a projection module 130. The housing 122 also includes a first housing 132 and a second housing 134. The first housing 132 can be fixed to the first bracket 110. The projection lens 116 extends from the multimedia processing module 114 in the same direction as the assembly direction, which means that one side of the projection lens 116 is fixed to the first housing 132 and extends in the -Z axis direction in Figure 4. After the first housing 132 and the second housing 134 are assembled together, there is a receiving portion between the first housing 132 and the second housing 134, and the processing circuit 124 and the projection module 130 can be disposed in the receiving portion. The processing circuit 124 can analyze the image and sound signals from the multimedia signal. The projection module 130 converts the image signal into a projected image and projects it onto the projection lens 116, allowing the user to view the projected image through the lens 116. It should be noted that the multimedia auxiliary device 10 is fixed to the glasses 20, and the projection lens 116 is located in front of the frame 202 of the glasses 20. Therefore, the user can view the projected image through a lens 206 embedded in the frame 202, allowing for a clear view of the projected image. The projection lens 116 is a light-transmitting lens; when the user views the projection lens 116, they can simultaneously see the projected image and an ambient scene, combining them to create an augmented reality scene.

[0021] A sound acquisition module 126 is embedded in the first housing 132 and is used to generate and transmit ambient sound information based on an ambient sound. An image acquisition module 128 is embedded in the first housing 132 and is used to generate and transmit ambient image information based on an ambient image. The processing circuit 124 can transmit the ambient sound information and ambient image information through a network for reception by a remote device. In some embodiments, the auxiliary display group 104 further includes a power supply module 136, which is disposed in the housing and supplies power to the processing circuit 124, the sound acquisition module 126, the image acquisition module 128, and the projection module 130. The power supply module 136 may be, for example, a battery or a power conversion circuit, which can extract external power and convert the external power into power that can be used by the multimedia processing module 114.

[0022] As shown in Figure 3, in some embodiments, the speaker module 106 has a sound output section 138 with a playback direction perpendicular to the assembly direction (as shown in Figure 3, the sound signal is played towards the Y-axis), allowing the sound signal to be played towards the user's ears. Specifically, the speaker module 106 can play sound signals via the sound output section 138. After the multimedia auxiliary device 10 is fixed to the glasses 20, the sound output section 138 is positioned near the user's ears so that the user can clearly hear the content of the sound signal. In some embodiments, the speaker module 106 is a directional speaker, and the energy of the sound information can be concentrated in the playback direction. The sound output section 138 can be configured at other angular positions of the speaker module 106 so that the playback direction is the same as the assembly direction (as shown in Figure 3, the sound signal is played towards the Z-axis). If the playback direction is the same as the assembly direction, the sound signal can be played directly towards the user's ears, reducing the energy consumption of the speaker module 106 and reducing the burden on the user when listening to the sound signal.

[0023] In some embodiments, the clamps (118, 119) are respectively connected to an elastic element 140, and the two elastic elements 140 are located in the gap 120. When the multimedia auxiliary device 10 is fixed to the glasses 20, the two elastic elements 140 can generate a frictional force with the temple 204 to increase the clamping force of the clamping member 108 on one of the temples 204.

[0024] Please refer to Figure 5, which is a schematic diagram of a multimedia auxiliary device connected to a mobile communication device in some embodiments of the present invention. In some embodiments, one of the clamps (118, 119) has a signal transmission unit 142. The signal transmission unit 142 is used to transmit multimedia signals to the multimedia processing module 114. The signal transmission unit 142 may be a transmission interface, which can be connected to a signal connection line 302 of a mobile communication device 30, so that the mobile communication device 30 can transmit multimedia signals to the multimedia processing module 114 via the signal transmission unit 142. The transmission interface may be, for example, a Universal Serial Bus (USB), a High Definition Multimedia Interface (HDMI), a parallel interface, or a serial interface. The signal transmission unit 142 may also be a wireless transmission circuit. The mobile communication device 30 can transmit multimedia signals to the multimedia processing module 114 through wireless transmission technology. The wireless transmission circuit may be, for example, a circuit with a Bluetooth, Wi-Fi, or ZigBee transmission chip.

[0025] As shown in FIG5, in some embodiments, the signal transmission unit 142 is used as an example as a transmission interface. The signal transmission unit 142 has a connection direction, which can be the same as the assembly direction (the connection direction is parallel to the assembly direction), so that the signal connection line 302 is connected to the signal transmission unit 142 along the Z-axis direction in FIG5. The connection direction can also be perpendicular to the assembly direction, so that the signal connection line 302 is connected to the signal transmission unit 142 along the Y-axis direction in FIG5.

[0026] Please refer to Figures 1, 6, and 7 together. Figure 6 is a front view of the multimedia auxiliary device in some embodiments of the present invention. Figure 7 is a schematic diagram of Figure 6 from a top view. As shown in Figures 1, 6, and 7, the auxiliary display group 104 also includes another multimedia processing module 144 and another projection lens 146. The multimedia processing module 144 is fixed to the other side of the first bracket 110 and is used to generate image signals and sound signals. The projection lens 146 is used to project the image signals. The two multimedia processing modules (114, 144) can have the same structure and function (please refer to the description of the aforementioned multimedia processing module 114). Image signals from the same source can be transmitted to the two multimedia processing modules (114, 144), so that the two multimedia processing modules (114, 144) can play image signals from the same source simultaneously or at different times. Taking video conferencing as an example, the image signal can include a conference video and a presentation video. Multimedia processing module 114 can project the conference video onto projection lens 116, and multimedia processing module 144 can project the presentation video onto projection lens 146. In this way, users can simultaneously view the conference video and presentation video for augmented reality conferencing. The two multimedia processing modules (114, 144) can also simultaneously play either the conference video or the presentation video.

[0027] In some embodiments, the two projection lenses (116, 146) correspond to the positions of the two frames 202, respectively. Both eyes of the user can view the image signals projected by the projection lenses (116, 146) through the glasses 20. In some embodiments, the two projection lenses (116, 146) extend in the same direction. For example, projection lens 116 extends from the multimedia processing module 114 towards the assembly direction (as shown in Figure 6 - Z-axis direction), and projection lens 146 extends from the multimedia processing module 144 towards the assembly direction. After the multimedia auxiliary device 10 is fixed to the glasses 20, the two projection lenses (116, 146) can be respectively positioned at the positions of the two frames 202.

[0028] The multimedia auxiliary device 10 also includes another speaker module 148. The speaker module 148 is fixed to the second bracket 113 and used to play audio signals. The two speaker modules (106, 148) can have the same structure and function (please refer to the description of speaker module 106 above). Audio signals from the same source can be transmitted to the two speaker modules (106, 148) respectively, allowing the two speaker modules (106, 148) to play audio signals from the same source simultaneously or at different times. Taking video conferencing as an example, the multimedia processing module 114 can transmit the left and right channels of the audio signal to the two speaker modules (106, 148) for playback respectively.

[0029] As shown in Figure 6, in some embodiments, the multimedia assistive device 10 further includes another clamping member 150. The clamping member 150 is fixed to the second bracket 113 and located between the multimedia processing module 144 and the speaker module 148. As shown in Figure 7, in some embodiments, the clamping member 150 and the multimedia processing module 114 have a first distance D1, and the clamping member 150 and the multimedia processing module 144 have a second distance D2, wherein the first distance D1 is substantially equal to the second distance D2. In this way, the two clamping members (108, 150) can evenly distribute the weight of the two multimedia processing modules (114, 144) and maintain balance. The two clamping members (108, 150) and the nose pad of the glasses 20 (not shown) can form a three-point support, so that when the multimedia assistive device 10 is fixed to the glasses 20, the multimedia assistive device 10 can be maintained at a fixed angle relative to the glasses 20.

[0030] As shown in Figures 1 and 6, in some embodiments, the clamping member 150 has two clamping plates (152, 153), and a gap 154 ​​is formed between the two clamping plates (152, 153). The gap 120 between the two clamping plates (118, 119) and the gap 154 ​​between the two clamping plates (152, 153) can have the same assembly direction. The two gaps (120, 154) can be installed on the two temples 204 respectively in the same assembly direction, so that the multimedia auxiliary device 10 can be fixed to both sides of the glasses 20. Each of the two clamping plates (152, 153) is connected to an elastic element 156, and the two elastic elements 156 are located in the gap 154. When the multimedia auxiliary device 10 is fixed to the glasses 20, the two elastic elements 156 of the clamping member 150 can generate a frictional force with the temples 204 to increase the clamping force of the clamping member 150 on the temples 204.

[0031] As shown in Figure 6, in some embodiments, the speaker module 148 has a sound output section 158, which has a playback direction perpendicular to the assembly direction (as shown in Figure 6, the sound signal is played in the Y-axis direction), so that the sound signal can be played around the user's ears. In some embodiments, the two sound output sections (138, 158) are respectively arranged in opposite positions, so that the user's ears can receive the sound signal at the same distance.

[0032] In some embodiments, when the auxiliary display group 104 is implemented as a single multimedia processing module 114 and projection lens 116 (as shown in FIG1), the multimedia auxiliary device 10 may also be configured with two clamping members (108, 150). For example, clamping member 108 is configured on the second bracket 112 and clamping member 150 is configured on the second bracket 113. After the multimedia auxiliary device 10 is fixed to the glasses 20, the two clamping members 108 can stably fix the second brackets (112, 113) on both sides of the auxiliary display group 104 to the temples 204.

[0033] In summary, in some embodiments, the multimedia assistive device 10 can be fixed to the glasses 20 via the clamp 108, allowing the user to view the image signal projected onto the projection lens 116. After the multimedia assistive device 10 is fixed to the glasses 20, the projection lens 116 is positioned at the corresponding position of the frame 202, allowing the user to view the image signal projected onto the projection lens 116 through the glasses 20. Furthermore, the speaker module 106 can be placed near the user's ear, allowing the user to listen to the sound signal played by the speaker module 106. Thus, the user can fix the multimedia assistive device 10 to the glasses 20 while wearing the glasses 20 to obtain image and / or sound signals for augmented reality conferencing.

[0034] The above-described embodiments are only for illustrating the technical ideas and features of this case. Their purpose is to enable those skilled in the art to understand the content of this case and implement it accordingly. They should not be used to limit the scope of the patent in this case. That is, all equivalent changes or modifications made in accordance with the spirit disclosed in this case should still be covered within the scope of the patent application in this case.
