Description

Technical Field

[0001] The utility model relates to a wall chart with sound. Background Art

[0002] The circuit device in the audio wall chart has an upper line, a lower line and an isolation layer between the upper line and the lower line. At present, the material of the audio wall chart uses coated paper or PVC or PET as the graphic layer, and the surface has the first printed graphic of the wall chart. These materials are prone to creases during use, and the coated paper is not waterproof. In addition, when the audio wall chart is assembled, each layer structure is combined by gluing. If ordinary glue is used, the environmental protection level cannot meet the requirements, and environmentally friendly glue is required, which is costly. In addition, the glue bonding combination is prone to defects such as overflowing glue during processing. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the technical problem solved by the utility model is to provide an audio wall chart with a simple structure, which does not require glue to be assembled and is not prone to creases.

[0004] In order to solve the above technical problems, the utility model adopts the following technical scheme: an audio wall chart, comprising a graphic layer, an isolation layer and a sealing bottom layer, the surface of the graphic layer is printed with a first printed graphic, characterized in that: the graphic layer comprises a first non-woven fabric main layer, the first printed graphic is printed on the upper side of the first non-woven fabric main layer, the lower side of the first non-woven fabric main layer is a coating surface, and the coating surface on the lower side of the first non-woven fabric main layer is printed with an upper line circuit, the sealing bottom layer comprises a second non-woven fabric main layer, the upper side of the second non-woven fabric main layer is a coating surface, and the coating surface on the upper side of the second non-woven fabric main layer is printed with a lower line circuit, the isolation layer is arranged between the first non-woven fabric main layer and the second non-woven fabric main layer, and the isolation layer is provided with connecting through holes for correspondingly connecting the upper and lower line pressing points under pressure, and the edge of the first non-woven fabric main layer and the edge of the second non-woven fabric main layer are welded to each other by ultrasonic welding lines.

[0005] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0006] For example, the lower side of the cover layer is printed with a second printed image.

[0007] Among them, the ultrasonic welding line is an intermittent sealing line.

[0008] For example, at least two rows of ultrasonic welding lines are arranged inside and outside.

[0009] After further optimization, two rows of ultrasonic welding lines are arranged inside and outside, and the intermittent positions of the intermittent sealing lines adjacent to each other inside and outside are staggered.

[0010] In addition, the audio wall chart also includes a sound box, a speaker is arranged in the sound box, at least two positioning pins are arranged on the shell of the sound box, and positioning connection holes are respectively arranged on the graphic layer, the isolation layer and the cover layer. There are at least two positioning connection holes on the graphic layer, the isolation layer and the cover layer, and the positioning connection holes are arranged corresponding to the positioning pins on the sound box.

[0011] For example, the shell of the sound box includes an upper shell and a lower shell, the positioning pin includes an upper pin column and a lower pin column, the upper pin column is located on the upper shell, the lower pin column is located on the lower shell, the upper pin column and the lower pin column are arranged correspondingly up and down, and the upper shell and the lower shell are connected by fasteners or buckles.

[0012] The beneficial effect of the utility model is that, in the audio wall chart, the basis of the graphic layer and the bottom cover layer are respectively made of non-woven fabrics, and the corresponding circuits (such as the upper line and the lower line) are respectively arranged on the coated surface of the non-woven fabric main layer, and the main body structure of the entire audio wall chart only requires three components: the first non-woven fabric main layer, the isolation layer and the second non-woven fabric main layer (except the sound box). The combined structure is simple and can also be combined by ultrasonic welding connection to avoid the use of glue. Moreover, after the non-woven fabric is used, the graphic layer and the corresponding circuits on the inner side of the bottom cover layer will not show through, avoiding affecting the printed graphics on the outside. In addition, after the non-woven fabric is used (the graphic layer and the bottom cover layer), the main body structure of the entire audio wall chart has relatively good waterproof performance, is not easy to get wet, is not easy to be affected by moisture, and is not easy to wrinkle or crease during use, and is not easy to cause damage to the printed graphics.

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the implementation of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0019] Referring to the accompanying drawings, an example of the present embodiment is an audio wall chart, comprising a graphic layer 1, an isolation layer 2 and a cover layer 3. The surface of the graphic layer 1 is printed with a first printed graphic 4. The first printed graphic 4 is usually printed in color. Graphics of different themes can be printed according to different needs, such as fruits and vegetables, transportation tools, numbers and letters, identities and occupations, etc.

[0020] In the present embodiment, the graphic layer 1 includes a first non-woven fabric main layer 5. The non-woven fabric material of the first non-woven fabric main layer 5 is used as a basis, and the first printed graphic 4 is printed on the upper side (i.e., the outer side) of the first non-woven fabric main layer 5. The lower side (i.e., the inner side) of the first non-woven fabric main layer 5 is set as a coating surface 6. The coating surface 6 on the lower side of the first non-woven fabric main layer 5 is printed with an upper line 7 so as to be connected to the circuit board in the sound box 8.

[0021] The bottom cover 3 includes a second non-woven fabric main body layer 9, based on the non-woven fabric material of the second non-woven fabric main body layer 9, the upper side (i.e., the inner side) of the second non-woven fabric main body layer 9 is set as a coating surface 10, and a lower line 11 is printed on the coating surface 10 on the upper side of the second non-woven fabric main body layer 9 to connect with the circuit board in the sound box 8. At the same time, the upper line 7 and the lower line 11 are also in a face-to-face setting state.

[0022] The upper line 7 and the lower line 11 (ie, the upper and lower lines) can be mainly printed with conductive paste such as carbon paste.

[0023] The isolation layer 2 is arranged between the first non-woven fabric main body layer 5 and the second non-woven fabric main body layer 9, and a connecting through hole 12 is arranged on the isolation layer 2. The connecting through hole 12 is used for connecting through holes 12 corresponding to the upper and lower line pressing points 17 being pressed. The thickness of the isolation layer 2 can separate the upper and lower lines. When the pressing points 17 on the upper line 7 and the lower line 11 are pressed, they can be connected through the connecting through hole 12 for use in coordination with control. The isolation layer 2 can be made of kraft paper or pearlescent film.

[0024] In addition, the edge of the first non-woven fabric main layer 5 and the edge of the second non-woven fabric main layer 9 (upper and lower) are welded to each other via ultrasonic welding lines 13, that is, the first non-woven fabric main layer 5 and the second non-woven fabric main layer 9 are connected and combined with each other by ultrasonic means, and the isolation layer 2 can be clamped by the first non-woven fabric main layer 5 and the second non-woven fabric main layer 9. The four sides of the sound wall chart are connected mainly by ultrasonic welding lines 13 to avoid gluing.

[0025] In the audio wall chart, the bases of the graphic layer 1 and the bottom cover layer 3 are respectively made of non-woven fabrics, and the corresponding circuits (such as the upper line circuit 7 and the lower line circuit 11) are respectively arranged on the coated surfaces 6 and 10 of the non-woven fabric main layer. The main structure of the entire audio wall chart only requires three components: the first non-woven fabric main layer 5, the isolation layer 2 and the second non-woven fabric main layer 9 (except the sound box 8). The combined structure is simple and can also be combined by ultrasonic welding connection to avoid the use of glue. Moreover, after the non-woven fabric is used, the corresponding circuits on the inner side of the graphic layer 1 and the bottom cover layer 3 will not show through, avoiding affecting the printed graphics on the outside. In addition, after the non-woven fabric is used (the graphic layer 1 and the bottom cover layer 3), the main structure of the entire audio wall chart has relatively good waterproof performance, is not easy to get wet, is not easy to be affected by moisture, and is not easy to wrinkle or crease (not obvious) during use, and is not easy to cause damage to the printed graphics.

[0026] The following optimization or further explanation may be performed based on the above embodiments.

[0027] For example, the lower side (ie, the outer side) of the cover layer 3 is printed with a second printed image, that is, the cover layer 3 also has printed images, and the lower line 11 on the inner side of the cover layer 3 will not show the second printed image and affect the outer side of the cover layer 3.

[0028] Among them, the ultrasonic welding line 13 is an intermittent sealing line 14. Further optimization, the ultrasonic welding line 13 (such as the intermittent sealing line 14) is set at least two rows inside and outside, and the connection is relatively more secure. For example, two rows of ultrasonic welding lines 13 are set inside and outside, and the intermittent positions of the intermittent sealing lines 14 adjacent to each other are staggered, which not only has a secure connection, but also has a relatively compact structure and does not occupy too much space for the audio wall chart.

[0029] In addition, the audio wall chart also includes a sound box 8, in which a speaker (not shown) is provided, and a circuit board (not shown) is also provided in the sound box 8, and the circuit board (its gold finger) will be connected with the upper line 7 and the lower line 11, which is a mature technology and will not be described in detail. Among them, at least two positioning pins (not shown) are also provided on the shell of the sound box 8, and positioning connection holes (not shown) are respectively provided on the graphic layer 1, the isolation layer 2 and the bottom cover 3. There are at least two positioning connection holes on the graphic layer 1, the isolation layer 2 and the bottom cover 3, respectively, and the positioning connection holes are correspondingly provided with the positioning pins on the sound box 8. The positioning connection holes on the graphic layer 1, the isolation layer 2 and the bottom cover 3 will be correspondingly sleeved on the positioning pins for matching positioning and connection, so that the relative positions of the graphic layer 1, the isolation layer 2 and the bottom cover 3 are more accurate, so as to facilitate assembly and make the corresponding lines correspond accurately up and down. For example, the shell of the sound box 8 includes an upper shell 15 and a lower shell 16, and the positioning pin includes an upper pin and a lower pin. The upper pin is located on the upper shell 15, and the lower pin is located on the lower shell 16. The upper pin and the lower pin are arranged correspondingly up and down, and the upper pin and the lower pin can be connected to each other. The upper shell 15 and the lower shell 16 are connected by fasteners (such as screws) or snaps.
