[0002] In traditional guitar making technology, the soundboard is one of the core parts of guitar making. Design a highly sensitive guitar.
[0003] In the prior art, in order to facilitate the sound of the guitar and increase the volume of the guitar, the panel needs to be very thin, but a thin single-board panel is not conducive to manufacturing, use and storage, and a thin single-board panel is easy to break. In the prior art, in order to solve the problem of the force of the guitar panel, the sound beam is often fixed on the inner side of the single-board panel (the side of the panel located at the resonance cavity) to enhance the rigidity of the panel, but this method cannot achieve the effect of increasing the volume.
[0004] Therefore, it is difficult for the panel structure in the prior art to increase the volume while ensuring the structural strength. Utility Model Content

[0008] The resonant sound board is located between the panel body and the back plate of the plucked string instrument, the outer edge of the resonant sound board is fixedly connected to the side plate of the plucked string instrument, and the vibration transmission component is fixedly connected to the panel body and the resonant sound board for transmitting the vibration of the panel body to the resonant sound board.
[0009] Preferably, the thickness of the resonant sound board is not greater than that of the panel body.

[0013] Preferably, the panel assembly further comprises a support plate, which is fixed to the inner side of the panel body and is located between the sound hole and the bridge, and the resonant soundboard, the side panel and the support plate jointly enclose a resonant cavity;
[0014] The support plate is provided with a through hole, and the through hole communicates with the resonance cavity and the resonance cavity of the plucked instrument.
[0015] Preferably, the panel assembly further comprises a lining strip, the lining strip is fixed to the inner side of the side panel of the plucked string instrument, and the resonant soundboard is fixedly connected to the lining strip.

[0029] The embodiment of the utility model provides a panel assembly and a plucked string instrument with a resonant soundboard. The vibration transmitted from the panel body is amplified by the resonant soundboard to generate a larger amplitude, thereby increasing the volume of the plucked string instrument.
[0030] Combine the following Figure 1 and Figure 2The technical solution provided by the utility model is described in more detail.
[0031] Embodiment 1:
[0032] like Figure 1 and Figure 2 As shown, the panel assembly with a resonant soundboard 1 provided by the utility model comprises a panel body 2, the resonant soundboard 1 and a vibration transmission member, wherein: the resonant soundboard 1 is located between the panel body 2 and the back plate of the plucked string instrument, the outer edge of the resonant soundboard 1 is fixedly connected to the side plate 6 of the plucked string instrument, and the vibration transmission member is fixedly connected to the panel body 2 and the resonant soundboard 1, and is used to transmit the vibration of the panel body 2 to the resonant soundboard 1.
[0033] The "panel body 2" refers to the plate body on which the strings and the bridge are fixed to the resonance box. In the prior art, the panel body 2, the side panels 6 and the back panel together form a resonance cavity of the plucked string instrument.
[0034] In this embodiment, the plucked string instrument may be a guitar, a ukulele, a folk instrument, etc. The plucked string instrument is described below by taking a guitar as an example.
[0035] See also Figure 1 and Figure 2 As shown, the structure of the back plate is omitted in the figure. Figure 1 The structure of the resonance soundboard 1 is omitted.
[0036] The panel assembly of this embodiment has a resonant soundboard 1, and the resonant soundboard 1 is located between the panel body 2 and the back panel. The resonant soundboard 1 and the panel body 2 are separated by a resonance transmission member. The resonant soundboard 1 will not affect the vibration of the panel body 2 itself too much. The vibration of the strings drives the panel body 2 to vibrate through the lower nut and the bridge. The vibration of the panel body 2 is transmitted to the resonant soundboard 1 through the vibration transmission member. The resonant soundboard 1 resonates, and the vibration transmitted from the panel body 2 is amplified by the resonant soundboard 1 to produce a larger amplitude, thereby increasing the volume of the plucked instrument.
[0037] Furthermore, due to the presence of the resonant sound board 1 , there is no need to reduce the thickness of the panel body 2 too much, so as to avoid affecting the structural strength of the panel body 2 .
[0038] As an optional implementation, in this embodiment, the thickness of the resonant sound board 1 is not greater than the panel body 2 .
[0039] In other words, the resonance soundboard 1 is thin in texture. When an object vibrates, the amplitude determines the volume. The larger the amplitude, the louder the volume, and vice versa. The resonance soundboard 1 is thin in texture and can vibrate with the maximum amplitude, thereby achieving the effect of increasing the volume.
[0040] In order to prevent the resonant sound board 1 from breaking and improve its structural strength, as an optional embodiment, an inner sound beam is fixed to the side of the resonant sound board 1 facing the panel body 2, and / or, see Figure 2 As shown, an outer sound beam 3 is fixed to the side of the resonant sound board 1 that is away from the panel body 2 .
[0041] That is, the inner sound beam may be fixed only on the side of the resonant sound board 1 facing the panel body 2, or the outer sound beam 3 may be fixed only on the side of the resonant sound board 1 facing away from the panel body 2, or the inner sound beam may be fixed on the side of the resonant sound board 1 facing the panel body 2 and the outer sound beam 3 may be fixed on the side of the resonant sound board 1 facing away from the panel body 2 at the same time.
[0042] The above structure can improve the structural strength of the resonance sound board 1, play a role in protecting the resonance sound board 1, and prevent the resonance sound board 1 from breaking when vibrating.
[0043] The resonant soundboard 1 of this embodiment can be made of spruce, carbon fiber, etc. to ensure the resonance effect.
[0044] See also Figure 2 As shown, the outer sound beams 3 are arranged at intervals along the width direction (or length direction) of the resonant sound board 1 to prevent the amplitude of the resonant sound board 1 from being too small.
[0045] As an alternative embodiment, see Figure 1 As shown, the vibration transmission member of this embodiment includes a carbon fiber tube 8, and two ends of the carbon fiber tube 8 are fixedly connected to the panel body 2 and the resonance sound board 1 respectively.
[0046] The structure of the carbon fiber tube 8 is light in texture and can better transmit the vibration of the panel body 2 to the resonant sound board 1, and the inner cavity of the carbon fiber tube 8 is conducive to the formation of resonance.
[0047] As an alternative embodiment, see Figure 1 As shown, the resonant soundboard 1 covers the portion of the bridge corresponding to the inner side of the panel body 2, or, as an alternative embodiment not shown in the figure, the resonant soundboard 1 completely covers the inner side of the panel body 2.
[0048] See also Figure 1 Since the vibration of the panel body 2 is mostly concentrated at the position of the panel body 2 corresponding to the bridge, the resonant soundboard 1 is located at the part of the corresponding bridge inside the panel body 2. The carbon fiber tube 8 (vibration transmission component) transmits most of the vibration of the panel body 2 to the resonant soundboard 1. The resonant soundboard 1 undergoes elastic deformation, amplifying the vibration of the panel body 2, generating a larger amplitude, thereby increasing the volume.
[0049] Of course, the resonance sound board 1 may completely cover the inner side of the panel body 2 .
[0050] As an alternative embodiment, see Figure 1 As shown, when the resonant soundboard 1 covers the portion of the corresponding bridge on the inner side of the panel body 2, the panel assembly also includes a support plate 4, which is fixed to the inner side of the panel body 2 and is located between the sound hole 7 and the bridge. The resonant soundboard 1, the side panel 6 and the support plate 4 jointly enclose a resonant cavity; a through hole 41 is provided on the support plate 4, and the through hole 41 connects the resonant cavity and the resonance cavity of the plucked instrument.
[0051] The support plate 4 separates the panel body 2 from the resonant sound board 1. One side of the resonant sound board 1 is fixed on the support plate 4. The resonant sound board 1, the side plate 6 and the support plate 4 together enclose a resonant cavity, which can improve the resonance effect.
[0052] In order to facilitate the fixing of the outer edge of the resonant sound board 1 on the side board 6, as an optional embodiment, see Figure 1 As shown, the panel assembly further comprises a lining strip 5, which is fixed to the inner side of the side panel 6 of the plucked string instrument, and the resonant soundboard 1 is fixedly connected to the lining strip 5. The lining strip 5 has a supporting plane 51 for pasting the resonant soundboard 1.
[0053] See also Figure 1 and Figure 2 As shown, the lining strip 5 can be adhered to the inner side of the side panel 6 by glue or the like, and the outer edge of the resonant sound board 1 is adhered to the supporting plane 51 of the lining strip 5, thereby achieving the fixation of the resonant sound board 1.
[0054] See also Figure 1 and Figure 2 As shown, the support plate 4 is at the same height as the lining strip 5, and the resonant soundboard 1 is fixedly pasted on the lining strip 5 and the support panel, thereby achieving the fixation of the resonant soundboard in the guitar.
[0055] As an alternative embodiment, see Figure 1 As shown, a reinforcing sound beam 21 is fixed to the inner side of the panel body 2 to ensure the structural strength of the panel body 2.
[0056] The panel assembly with the resonant soundboard 1 of this embodiment is manufactured as follows:
[0057] 1. First, paste the inner and outer sound beams 3 of the resonance soundboard 1 on the inner and outer sides of the resonance soundboard 1, then paste the carbon fiber tube 8 on the inner side of the panel body 2, and then paste the lining strip 5 on the side panel 6. Finally, put the handle, panel body 2 and side panel 6 into the barrel mold for debugging and pasting to complete the production of half barrel.
[0058] 2. Apply glue evenly on the lining strip 5, carbon fiber tube 8 and harmonic beam, put the resonance sound board 1 into their corresponding gluing positions, and use the support plate 4 to stick the resonance sound board 1 together with the lining strip 5, carbon fiber tube 8 and harmonic beam.
[0059] The panel assembly with the resonant soundboard 1 of this embodiment has the following working principle:
[0060] The resonant soundboard 1 will not affect the vibration of the panel body 2 itself too much. The vibration of the strings drives the panel body 2 to vibrate through the lower nut and the bridge. The vibration of the panel body 2 is transmitted to the resonant soundboard 1 through the vibration transmission part, and the resonant soundboard 1 resonates. The resonant soundboard 1 is thin in texture. When an object vibrates, the amplitude determines the volume. The larger the amplitude, the louder the volume, and vice versa. The resonant soundboard 1 is thin in texture and can vibrate with the maximum amplitude. The vibration transmitted from the panel body 2 is amplified by the resonant soundboard 1, generating a larger amplitude, thereby increasing the volume of the plucked instrument.
[0061] Due to the presence of the resonant soundboard 1, there is no need to reduce the thickness of the panel body 2 too much to prevent affecting the structural strength of the panel body 2. When the panel body 2 is a single-board panel, it can ensure the rich timbre of the plucked instrument and at the same time increase the volume of the plucked instrument.
[0062] Embodiment 2:
[0063] The guitars in the prior art, made of single-board panels, have rich timbre but lack volume.
[0064] The plucked string instrument of this embodiment, see Figure 1 and Figure 2 As shown, it includes the panel assembly having the resonant soundboard 1 described above.
[0065] When the panel body 2 of the plucked string instrument is a single-board panel, the timbre of the plucked string instrument can be ensured to be rich, and the volume of the plucked string instrument can be increased due to the panel assembly.
[0066] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
[0067] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.
[0068] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
