The first layer of glass 21 and the second layer of glass 22 are separated by the second fixing structure 25 to form a second hollow layer 27, so that the first layer of glass 21, the second layer of glass 22 and the third layer of glass 23 form a double-layer hollow glass structure.

[0033] In a preferred embodiment, please refer again to Figure 1 The main structure 2 also includes a carbon fiber outer frame 28, which is wrapped around the edges of the first layer of glass 21, the second layer of glass 22 and the third layer of glass 23, and is used to protect and install the first layer of glass 21, the second layer of glass 22 and the third layer of glass 23, but is not limited to this.

The first fixed structure 24, the second fixed structure 25, the plurality of partition strips 3 and the plurality of sound-generating mechanisms 4 are located in the black ink area 201, but it is not limited thereto.

[0035] A plurality of partition strips 3 are arranged in the second hollow layer 27, and the upper and lower ends thereof are respectively bonded to the first layer of glass 21 and the second layer of glass 22 by adhesive. The plurality of partition strips 3 divide the second hollow layer 27 into a plurality of pronunciation areas 5, and the plurality of pronunciation areas 5 are not interconnected to prevent the pronunciation areas 5 from interfering with each other when pronouncing. Figure 3 , which shows an embodiment of the present invention Figure 1 Schematic diagram of the internal structure of the sound cavity partition structure 1 of the transparent sound-generating device shown in FIG. Preferably, the plurality of partition strips 3 and the second fixed structure 25 are an integrated structure, and the plurality of partition strips 3 and the second fixed structure 25 form a plurality of special-shaped partition strips 7, and each of the special-shaped partition strips 7 is a closed-loop structure, and the upper and lower ends thereof are respectively bonded to the first layer of glass 21 and the second layer of glass 22, so that the formed plurality of sound-generating areas 5 are not connected, and the shape of the special-shaped partition strips 7 can be made according to actual needs, but is not limited thereto.

[0036] In a preferred embodiment, the first fixed structure 24, the second fixed structure 25 and the plurality of partition strips 3 are all aluminum spacer strips, but this is not limited to this. Technical personnel in this field can also select other suitable first fixed structure 24, second fixed structure 25 and multiple partition strips 3 according to actual needs.

[0037] In a preferred embodiment, please also refer to Figure 3 and Figure 6 , wherein 6 shows an embodiment of the present invention Figure 4The schematic diagram of the internal structure of the sound cavity partition structure 1 of the transparent sound-emitting device shown in . The multiple pronunciation areas 5 include at least one bass area 51 and at least one mid-high area 52. The at least one bass area 51 is used to provide bass audio playback, and the at least one mid-high area 52 is used to provide mid-high audio playback, but it is not limited to this. The embodiment further discloses that the number of at least one bass area 51 is two, the number of at least one mid-high area 52 is two, the two bass areas 51 are symmetrically arranged on both sides of the short side of the main structure 2, and the two mid-high areas 52 are symmetrically arranged on both sides of the long side of the main structure 2, but it is not limited to this.

[0038] The plurality of sound generating mechanisms 4 are correspondingly arranged in the plurality of sound generating areas 5. Please also refer to Figure 1 and Figure 4 ,in Figure 4 Another structural schematic diagram of the sound cavity partition structure 1 of the transparent sound-generating device according to an embodiment of the present invention is shown. The multiple sound-generating mechanisms 4 disclosed in this embodiment can be multiple power units 41 or multiple sound-generating units 42. As for which structure to choose as the sound-generating mechanism 4, those skilled in the art can choose according to actual sound generation needs.

[0039] In a preferred embodiment, please refer again to Figure 1 The multiple sound-generating mechanisms 4 are multiple power units 41, and the two ends of the multiple power units 41 are respectively connected to the first layer of glass 21 and the second layer of glass 22, and the connection method is usually connected by adhesive bonding, and the adhesive used must be able to transmit structural stress, but it is not limited to this.

Preferably, the number of power units 41 arranged in at least one bass area 51 and at least one mid-high area 52 is the same, but it is not limited to this.

[0040] Multiple power units 41 produce sound by driving the first layer of glass 21 to vibrate. Under the action of the same power unit 41, the larger the area, the greater the vibration amplitude and the better the bass effect, it is preferred to set the area of ​​the bass region 51 to be larger than the area of ​​the mid-high frequency region 52 to improve the bass sound effect, but it is not limited to this.

[0041] In another preferred embodiment, when the sound cavity partition structure 1 of the transparent sound-emitting device emits sound, the circuit that drives the power unit 41 to vibrate is usually arranged in the second hollow layer 27, and the audio signal is divided into a low-frequency signal and a mid-high frequency signal by means of a crossover, and the signals are transmitted accordingly to the power unit 41 located in at least one bass area 51 and the power unit 41 located in at least one mid-high frequency area 52. At this time, the bass area 51 provides bass audio playback for an independent bass speaker, and the mid-high frequency area 52 provides mid-high frequency audio playback for an independent mid-high frequency speaker, but it is not limited to this.

One side of the multiple sound-generating units 42 is attached to the second layer of glass 22, and is correspondingly arranged in at least one bass area 51 and at least one mid-high area 52. Please refer to Figure 6 The corresponding setting here means that the bass sound unit 421 among the multiple sound units 42 is set in the bass area 51, and the mid-high frequency sound unit 422 among the multiple sound units 42 is set in the mid-high frequency area 52. Specifically, speakers with corresponding models and functions can be used according to the actual application scenarios to flexibly respond to the needs of different application scenarios.

[0043] The other side of the multiple sound units 42 is the sound side. Please also refer to Figure 4 and Figure 5 ,in Figure 5 An embodiment of the present invention is shown Figure 4 The schematic diagram of the top view of the sound cavity partition structure 1 of the transparent sound-emitting device shown in FIG. The first layer of glass 21 is also provided with a plurality of sound outlet holes 211 corresponding to the sound-emitting sides of the plurality of sound-emitting units 42. The audio signal is distributed through the frequency divider, and the mid-high frequency signal is distributed to the mid-high frequency sound-emitting unit 42, and the bass signal is distributed to the bass sound-emitting unit 42. In this way, the overall sound-emitting solution can achieve full-band response, effectively improving the volume and sound effect of the overall device.

At the same time, since each pronunciation area 5 is an independent closed space, it can also prevent moisture, dust, etc. from entering the transparent visible area 202 between the first layer of glass 21 and the second layer of glass 22 through the sound outlet hole 211, thereby avoiding affecting the light transmittance and haze of the transparent visible area 202, but it is not limited to this.
