Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to a guitar case and a digital guitar. Background Art

[0002] When the strings of an electric guitar vibrate, the pickup on the guitar body can detect the vibration information of the strings and convert it into a voltage or current analog signal in the electronic circuit. Then, through the wires connected to the effector, power amplifier and speaker, it can produce a loud sound with a variety of electric guitar tones. The innovative design of modern multi-functional electric guitars often has the effector, power amplifier, speaker and power supply built into the guitar body.

[0003] The digital guitar is a product of the development of science and technology. It uses sensors and electronic circuits to detect and obtain digital pitch information from the finger pressing circuit of the imitation string fretboard, and converts the information of plucking the strings into digital signals. Then, through the chip and corresponding algorithm software, it calculates the pronunciation information such as the pitch and volume of the sound to be played in real time, and then calls and plays the sampled sound source through the sound source module, and finally connects to the power amplifier and speakers for sound playback. Its sound-generating principle is similar to that of a digital piano.

[0004] The above multifunctional electric guitars and digital guitars all need to place the power supply, amplifier, speaker and various electronic circuit modules inside the guitar case, but the internal space of the guitar case is very limited. How to design and layout various modules in the smaller internal space of the guitar case while ensuring excellent sound quality, appropriate weight and convenient after-sales maintenance is the main difficulty at present.

[0005] In the prior art, one or more circuit boards and one or more small independent speakers are usually arranged in a guitar case that is not well sealed. Since the internal cavity volume of the independent speaker is too small, the woofer cannot produce a good bass effect in the independent speaker; and the small speaker can generally only accommodate a small number of speakers, the sound effect is single, and the effect of 2.0 stereo or 2.1 stereo plus bass cannot be achieved; however, if a larger woofer is installed for good sound effects, a large independent speaker is required, which increases the weight of the above two types of guitars, making them very inconvenient to play and carry.

[0038] In order to make the digital guitar produce high-quality sound effects, in the prior art, a small independent speaker is usually set in the guitar case of the digital guitar, and the tweeter, midrange speaker and woofer are all set in the independent speaker. Since the speaker is too small, the woofer cannot produce a good bass effect in the independent speaker; and the small speaker can generally only accommodate a small number of speakers, the sound effect is single, and the effect of 2.0 stereo or 2.1 stereo plus bass cannot be achieved; if a larger-sized woofer is installed for good sound effects, a large-volume independent speaker is required, which increases the weight of the digital guitar, making it very inconvenient to play and carry.

[0039] In order to solve the above problems, this embodiment provides a digital guitar. Figure 1 and Figure 2 , including a neck 1 and a guitar case, wherein the neck 1 is arranged on the guitar case, and two ends of a string-like fingerboard 2 are respectively connected to the neck 1 and the guitar case.

[0040] Specifically, see Figure 1 The piano box includes a box body 10, a partition 20 and a speaker assembly. The box body 10 includes a front panel 11, a side panel 12 and a rear panel 13. The front panel 11, the side panel 12 and the rear panel 13 can be together enclosed to form a storage space; the partition 20 is vertically arranged on the front panel 11, and is connected to the side panels 12 at both ends. The partition 20 divides the storage space into a first storage space 21 and a second storage space 22. The partition 20, the front panel 11, the side panel 12 and the rear panel 13 are all sealed and connected; the speaker assembly includes a tweeter, a midrange speaker and a woofer. The tweeter and the midrange speaker are respectively arranged in the second storage space 22 through independent sound boxes 30, and the woofer is arranged in the second storage space 22, so that the second storage space 22 is used as a woofer speaker for the woofer. Independent sound boxes 30 are provided for the tweeter and the midrange speaker to ensure the sound effects of the treble and the midrange, and the second accommodating space 22 is used as the sound box for the woofer, which not only saves the space of the guitar case, but also has a large enough sound box space to ensure the bass sound effect, thereby optimizing the design of the guitar case for the digital guitar.

[0041] Furthermore, the front plate 11 is provided with a first sound hole 111 and a second sound hole 112, wherein the first sound hole 111 corresponds to the position of the two independent sound boxes 30; and the second sound hole 112 corresponds to the position of the second accommodation space 22. The first sound hole 111 is used to transmit the sound of the tweeter and the midrange speaker. In this embodiment, the first sound hole 111 is configured as a mesh through hole, and the second sound hole 112 is configured as a round hole. The mesh through hole can prevent debris from entering the independent sound box 30 and prevent objects such as fingers from touching the independent sound box 30 and causing damage.

[0042] Specifically, the independent speaker 30 is detachably fixed in the second accommodating space 22 by screws. The area of ​​the independent speaker 30 attached to the front plate 11 is larger than the area of ​​the first sound hole 111 on the front plate 11. Sealing materials are provided on the contact surface between the first sound hole 111 and the independent speaker 30. When the screws are tightened, the sealing materials can be compressed to meet the sealing requirements of the second accommodating space 22. When the number of tweeters and midrange speakers needs to be increased or changed, the independent speaker 30 can be replaced. Since the independent speaker 30 and the woofer are hidden in the box 10, when the number and model of speakers are changed, adaptive changes to the appearance and structure of the digital guitar can be avoided, which can enhance versatility and reduce manufacturing costs.

[0043] Furthermore, a phase inversion tube 40 is also provided in the second accommodation space 22. One end of the phase inversion tube 40 is connected to the second sound hole 112, and the other end opens toward the woofer. The phase inversion tube 40 can invert the sound emitted by the woofer, that is, change the vibration waveform to enrich the sound quality of the woofer. The opening faces the woofer to enhance the sound quality, and the inverted sound is transmitted from the second sound hole 112.

[0044] Furthermore, a bass sound hole 131 is provided on the rear plate 13 at a position corresponding to the second accommodating space 22, and the sound of the bass speaker is transmitted from the bass sound hole 131. The sound of the bass speaker after phase inversion and the sound without phase inversion are transmitted at the same time, further enhancing the bass effect.

[0045] Specifically, one end of the bass reflex tube 40 is integrally connected to the second sound hole 112. The bass reflex tube 40 is integrally connected to the second sound hole 112, which not only makes the appearance of the digital guitar beautiful, but also the integral molding can enhance the strength of the box 10, especially the bending resistance of the front plate 11, and enhance the durability and service life of the digital guitar. In the present embodiment, the bass reflex tube 40 is configured as an L-shaped curved tube. In other embodiments, the bass reflex tube 40 includes a first tube 41 and a second tube 42, the other end of the first tube 41 is connected to the second tube 42, and the opening of the second tube 42 at one end away from the first tube 41 faces the woofer. Furthermore, the first tube 41 and the second tube 42 are nested or threadedly connected, and glue can be dripped into the threaded connection between the first tube 41 and the second tube 42 to strengthen the connection stability between the first tube 41 and the second tube 42.

[0046] The shape of the bass reflex tube 40 is determined by the specific volume of the second accommodating space 22 and the specific specifications of the selected woofer, after being calculated using a detailed bass reflex speaker audio analysis algorithm. The shape mainly includes parameters such as the length and inner diameter of the bass reflex tube 40. The shape and inner diameter of the bass reflex tube 40 are not specifically limited in the present application, and those skilled in the art may make adaptive changes based on actual conditions.

[0047] Furthermore, the side panel 12 is integrally connected to the front panel 11, and the partition 20 is integrally connected to the side panel 12, and the partition 20 has the same height as the side panel 12. The integral formation of the side panel 12 and the front panel 11 makes the front appearance of the digital guitar more beautiful and has good sealing performance. The integral formation of the partition 20 and the side panel 12 can avoid the formation of a channel at the connection between the partition 20 and the side panel 12, thereby affecting the connection sealing in the second accommodating space 22, causing the sound of the woofer to leak from the gap and cannot be fully transmitted to the second sound hole 112. Furthermore, a seal is provided between the side panel 12 and the partition 20 and the rear panel 13. In this embodiment, the seal can be set as a sealing silicone strip to ensure the sealing of the second accommodating space 22.

[0048] Furthermore, the piano case also includes a mainboard 50, on which a functional chip and circuit connection lines are arranged, and the mainboard 50 is arranged in the first accommodation space 21 and is perpendicular to the front plate 11. The mainboard 50 is perpendicular to the front plate 11, which can reduce the use space of the mainboard 50 in the first accommodation space 21, thereby reducing the use space of the first accommodation space 21, and can maximize the second accommodation space 22 to enhance the sound effect of the woofer.

[0049] Furthermore, the piano case also includes a functional module 60, which is arranged on the side panel 12 near the main board 50 and is connected to the functional chip through a data cable. Specifically, the functional module 60 includes a charging port, an earphone port, a screen and a button 61. Specifically, the charging port is set as a type-c charging port 62, and the type-c charging port 62 can also be used as an earphone port. Since the main board 50 is provided with a functional chip and a circuit connection line that needs to be connected to the outside of the box 10, the first accommodating space 21 needs to be set as an open space. In this embodiment, a part of the side panel 12 of the first accommodating space 21 is missing to facilitate the functional chip and the circuit connection line to be connected to the outside of the box 10. When other modules need to be added, they can also be conveniently placed in the first accommodating space 21, and the sealing effect of the second accommodating space 22 will not be affected.

[0050] Further, see Figure 3 The piano case also includes a battery compartment 70, which is disposed in the first accommodation space 21. The battery compartment 70 also includes a cover 71, which can open or close the battery compartment 70. A clearance hole is provided at a position corresponding to the battery compartment 70 on the rear plate 13 to avoid the cover 71. When replacing the battery, it is only necessary to open the cover 71 to replace it without disassembling the rear plate 13, which makes battery replacement more convenient. Specifically, the cover 71 can be set to a cover type with a slide lock or a flip type with a snap lock.

[0051] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
