Description

Technical Field

[0001] The utility model relates to the field of electronic guzheng, in particular to an electronic guzheng with a built-in sound structure. Background Art

[0002] The electronic guzheng is different from the traditional guzheng. It can pick up the vibration of the strings through a pickup and convert the vibration signal of the strings into an electrical signal. Therefore, the electronic guzheng can be directly connected to an external speaker through its interface to amplify its sound.

[0003] However, if the electronic guzheng needs to be connected to an external sound system, an additional sound system is required, which causes certain inconveniences for carrying and using the electronic guzheng outside. Based on this, the utility model provides an electronic guzheng with a built-in sound structure, so that the electronic guzheng does not need an additional sound system when used, thereby achieving the purpose of improving the convenience of use of the electronic guzheng. Utility Model Content

[0004] Based on this, the utility model provides an electronic guzheng with a built-in sound structure, comprising an electronic guzheng body, a cavity formed in the electronic guzheng body, an installation box installed in the cavity, the installation box comprising a first box body and a second box body arranged on the left and right, the left end of the first box body is opened to form a first installation port, and the right end of the second box body is opened to form a second installation port; speakers of the same specifications are installed in the first installation port and the second installation port, and the speaker installed in the first installation port is arranged to face left, and the speaker installed in the second installation port is arranged to face right.

[0005] In the utility model, the installation box arranged in the cavity is used as the sound structure of the electronic guzheng body. Specifically, the sound structure includes a first box body and a speaker installed thereon to form a sound box structure, and a second box body and a speaker installed thereon to form a sound box structure. Among them, by connecting the speakers on the first box body and the second box body to the pickup of the electronic guzheng body, the sound box structure formed by the speaker and the first box body and the second box body can emit corresponding sounds as the electronic guzheng body is played, thereby achieving the effect of sound amplification. It can be seen that the electronic guzheng of the utility model has a sound structure with a sound amplification function, and no additional sound system is required when carrying and using it outside, that is, the electronic guzheng of the utility model has good convenience in use.

[0006] At the same time, in the utility model, the speakers on the first box body and the second box body on the installation box are arranged symmetrically and have the same specifications. Therefore, when the speakers vibrate and sound, the amplitude and frequency of the two speakers are the same, and the vibration directions are opposite. It can be seen that the vibrations of the two speakers have the effect of canceling each other, which can reduce or even eliminate the vibration of the sound structure when it is working. Correspondingly, the vibration transmitted to the electronic guzheng body by the installation box will also be very slight, or even no vibration will be transmitted to the electronic guzheng body. That is, the utility model can ensure that the vibration of the speakers when the sound structure is working will not affect the normal playing of the electronic guzheng under the premise of the built-in sound structure. Among them, preferably, the first box body and the second box body are also arranged symmetrically.

[0007] Furthermore, the electronic guzheng body is provided with a first sound-transmitting window and a second sound-transmitting window. The first sound-transmitting window is connected to the cavity and is located on the left side of the first installation opening, and the second sound-transmitting window is connected to the cavity and is located on the right side of the second installation opening.

[0008] In the present invention, the first sound-transmitting window is provided on the left side of the first installation opening, and is used for the speaker installed at the first installation opening to transmit the sound out of the cavity, and the second sound-transmitting window is provided on the right side of the first installation hole, and is used for the speaker installed at the second installation opening to transmit the sound out of the cavity. Preferably, the first sound-transmitting window and the second sound-transmitting window are formed by a plurality of through holes arranged in an array and provided on the electronic guzheng body, so that the first sound-transmitting window and the second sound-transmitting window have a certain protective effect under the premise of ensuring that the sound of the speaker can be transmitted out of the cavity, and play a role in preventing foreign matter from entering the cavity through the first sound-transmitting window and the second sound-transmitting window.

[0009] Furthermore, a flange is formed on the side wall of the installation box around the installation box, and a plurality of vertically arranged rubber sleeves are arranged at intervals on the flange; an abutment platform is provided at the bottom of the cavity corresponding to the rubber sleeve, and the upper surface of the abutment platform abuts against the bottom end of the rubber sleeve, and a plug column is also vertically provided on the upper surface of the abutment platform, and the plug column is inserted into the rubber sleeve and is tightly fitted with the rubber sleeve.

[0010] In the utility model, the installation box is installed at the bottom of the cavity through the rubber sleeve thereon, thereby realizing the installation of the installation box in the cavity, wherein the upper surface of the abutment table abuts against the bottom end of the rubber sleeve to support the rubber sleeve, and the insertion column on the abutment table is fixedly inserted into the rubber sleeve to fix the rubber sleeve.

[0011] In the utility model, since the rubber sleeve has a certain elasticity, the rubber sleeve has a buffering effect, which can effectively reduce the vibration transmitted to the electronic guzheng body by the installation box when it is working. It can be seen that the utility model can further reduce the vibration transmitted to the electronic guzheng body by the installation box when the installation box has only slight vibration on the basis of the mutual offset of the vibrations of the speakers, and can further enhance the user experience when using the electronic guzheng body for playing.

[0012] Furthermore, the rubber sleeve includes two annular pressure blocks arranged upper and lower, and the two pressure blocks are connected by an annular connecting block, the connecting block is coaxially arranged with the pressure block, and the outer diameter of the connecting block is smaller than the outer diameter of the pressure block; the flange is provided with a mounting hole corresponding to the connecting block, the diameter of the mounting hole is the same as the outer diameter of the connecting block, the connecting block is embedded in the mounting hole, and the thickness of the connecting block is the same as the thickness of the flange.

[0013] In the present invention, when the rubber sleeve is embedded in the installation hole through the connecting block thereon, the two pressure blocks at the upper and lower ends of the rubber sleeve will respectively abut against the upper and lower surfaces of the flange, so that the rubber sleeve is fixedly connected to the flange. Among them, the insertion rod fixedly inserted in the rubber sleeve will fix the rubber sleeve on the abutment platform. At this time, the pressure blocks at the upper and lower ends of the rubber sleeve can respectively buffer the upward vibration and downward vibration of the installation box when the installation box has an up and down vibration, which can further reduce the vibration transmitted from the installation box to the electronic guzheng body, thereby further improving the user experience when using the electronic guzheng body to play.

[0014] Preferably, the rubber sleeve is prepared by integrally molding the rubber material.

[0015] Furthermore, an opening communicating with the mounting hole is formed at an edge of the flange corresponding to the mounting hole, and a width of the opening is smaller than a diameter of the mounting hole.

[0016] In the utility model, the connecting block of the rubber sleeve can be inserted into the mounting hole through the opening provided on the flange, so that the rubber sleeve can be conveniently installed on the flange, and the installation of the rubber sleeve is convenient. At the same time, the rubber sleeve can also be conveniently taken out from the mounting hole, so that the rubber sleeve can be conveniently replaced when the rubber sleeve is aged.

[0017] Furthermore, a power supply for supplying power to the speaker is also provided in the cavity.

[0018] In the utility model, the power source built into the cavity can conveniently use the electronic guzheng in a place without an external power source, wherein the power source can be a rechargeable lithium battery.

[0019] The principle and effect of the present invention are further described below in combination with the above technical solutions and the accompanying drawings:

[0020] In the utility model, the installation box arranged in the cavity is used as the sound structure of the electronic guzheng body. Specifically, the sound structure includes a first box body and a speaker installed thereon to form a sound box structure, and a second box body and a speaker installed thereon to form a sound box structure. Among them, by connecting the speakers on the first box body and the second box body to the pickup of the electronic guzheng body, the sound box structure formed by the speaker and the first box body and the second box body can emit corresponding sounds as the electronic guzheng body is played, thereby achieving the effect of sound amplification. It can be seen that the electronic guzheng of the utility model has a sound structure with a sound amplification function, and no additional sound system is required when carrying and using it outside, that is, the electronic guzheng of the utility model has good convenience in use.
