Problems solved by technology

[0006] One is that the side windows of rail transit or the glass on both sides of the car sunroof are relatively thick, and the displacement of the power unit is small, which makes it difficult to drive the glass to vibrate and produce sound, resulting in weak vibration amplitude, insignificant sound effect, and poor sound quality;
[0007] Second, if the piezoelectric speaker is directly placed in the hollow part of the rail traffic side window or the car sunroof, it will cause sound from both sides of the rail traffic side window or car sunroof, which not only causes sound wave loss, but also affects the rail traffic side window or car sunroof. causing noise pollution outside; and
[0008] The 3rd, the glass of the rail traffic side window of prior art rail traffic is bonded and cannot be easily disassembled for 30 years, and the lifespan of the electronic components is far less than the life span of the rail traffic side windows. When maintaining or replacing the electronic components, The glass of the rail transit side window needs to be removed, which is not convenient for the removal and maintenance of electronic components

Embodiment 1

[0047] Please refer to figure 1 , 3 , 4, and 5, when the transparent sound 1 of the one-way sound of the present invention was applied on the rail transit side window 7, the transparent sound 1 of the one-way sound included a structural member 2, a diaphragm 3 and a power unit 4, wherein Diaphragm 3 is a glass vibrating piece, please refer to Figure 5 As shown, structural part 2 is an L-shaped aluminum spacer, please refer to Figure 4 As shown, the rail transit side window 7 includes a transparent area A1 and an ink printing area A2.

[0048] Please refer to figure 1 As shown, the rail traffic side window 7 in the present invention includes an outer glass 71 and an inner glass 72, and a hollow portion 73 is arranged between the outer glass 71 and the inner glass 72, so that the rail traffic side window 7 has sound insulation and heat insulation performance, but not limited thereto.

[0049] Please refer to image 3 As shown, the power unit 4 is distributed and arranged...

Embodiment 2

[0053] Please refer to Figure 1-5 As shown, when the one-way sounding transparent sound 1 of the present invention is applied on the rail transit side window 7, the structure of the one-way sounding transparent sound 1 is basically the same as that of Embodiment 1, please refer to figure 2 As shown, the difference is that in this embodiment, a layer of functional layer 5 is pasted on the inner side of the diaphragm 3. The functional layer 5 is an NPD dimming film, and the gradual dimming function of the diaphragm 3 is realized through the NPD dimming film. In the present invention, there is no special requirement for the selection of the NPD dimming film, just refer to the conventional selection of those skilled in the art. The principle of how the NPD dimming film realizes the gradual dimming of the vibrating film 3 is well known to those skilled in the art, so it will not be repeated here.

[0054] Preferably, the size of the NPD dimming film is smaller than the size of t...

Embodiment 3

[0056] Please refer to Figure 1-5 As shown, when the one-way sound-emitting transparent sound 1 of the present invention is applied on the rail transit side window 7, the structure of the one-way sound-emitting transparent sound 1 is basically the same as that of Embodiment 2, the difference being that this embodiment The functional layer 5 is a PDLC dimming film, and the automatic dimming function of the diaphragm 3 is realized through the PDLC dimming film. In the present invention, there is no special requirement for the selection of the PDLC dimming film, just refer to the conventional selection of those skilled in the art. The principle of how the PDLC dimming film realizes the automatic dimming of the vibrating film 3 is well known to those skilled in the art, so details will not be described here.

[0057] Preferably, the size of the PDLC dimming film is smaller than the size of the diaphragm 3, so that the power unit 4 is directly connected to the diaphragm 3 instead...

Abstract

The invention relates to a transparent sound box of one-way sound output. The sound box is applied on a rail transportation side window or an automobile sunroof, and includes: a structure member, of which one end is disposed on one side of the rail transportation side window or the automobile sunroof; a vibration film, which is connected with the other end of the structure member, and is disposedon the rail transportation side window or the automobile sunroof through the structure member; and dynamic units, which are used for driving the vibration film to sound. One end of a dynamic unit is connected with the vibration film, and the other end is disposed on the rail transportation side window or the automobile sunroof through the structure member. When the sound box is applied on the railtransportation side window, a sound insulation function of the rail transportation side window is utilized, single-side sounding is realized, and the sound box also has functions of convenient disassembly and maintenance. When the sound box is applied on the automobile sunroof, the sound box can be used as a source of sound output from an upper position of an automobile, and an effect of omnidirectional sounding in the automobile can be achieved. In listening to music or other sounds, more spatial experience feeling is provided, and immersive sound enjoyment is created.

Description

technical field [0001] The invention relates to a sound, in particular to a transparent sound with one-way sound output. Background technique [0002] With the continuous development of electronic information technology, transparent display terminals are the general trend of the future development of the display industry. However, the display part and the sounding part of the smart terminal in the prior art are separated, and in addition to the display screen for display, external sounding parts such as speakers are also required. However, these external pronunciation components occupy a large space of the display terminal, thereby shrinking the display screen of the smart terminal and affecting the overall design aesthetics. [0003] The sounding principle of the traditional speaker is that the current carrying the sound signal passes through the speaker coil, and the coil with the current flowing through it is affected by the magnetic field force in the magnetic field. Th...
