Description

Technical field:

[0001] The utility model belongs to the technical field of audio technology, and more specifically relates to a combined audio sound-generating device. Background technology:

[0002] For products related to percussion music, the percussion pieces are made of a single material, and the same device generally only displays sounds of different scales produced by one material. There are also two levels of display methods. One type, such as a music box, can only display fixed preset sounds, and the other type is complex to operate and is only suitable for young and middle-aged people with certain thinking and hands-on abilities. It is not user-friendly for young participants. In addition, the transmission device of the percussion music device is generally exposed, which poses the risk of pinching and entanglement.

[0003] The national utility model patent with patent number 202220049213.3 discloses a demonstration mechanism that displays the timbre of different materials. The small ball at the front end of the striking rod hits the bells of different materials to produce vibrations and then make sounds, thereby realizing vertical comparison of the same material and horizontal comparison of different materials, guiding participants to explore and understand that different sound-emitting bodies have different timbres and tones due to different materials and structures, producing different sound effects, and achieving good exploratory properties.

[0004] However, audio sound is related to material, audio frequency and amplitude, both of which are related to the frequency and force of the tapping. The device has a balanced tapping frequency and force, and cannot display the differences in timbre and tone of the sound produced by audio frequency and amplitude. Utility model content:

[0005] In order to solve the above problems and overcome the shortcomings of the prior art, the utility model provides a combined audio sound-generating device;

[0006] The first technical problem to be solved is that audio is related to amplitude, which are both related to the knocking frequency and knocking force. The knocking frequency and knocking force of the device are balanced, and the difference in timbre and tone of the sound produced by the knocking frequency and knocking force cannot be displayed.

[0007] The specific technical solution of the utility model to solve the above technical problems is: the combined audio sound-generating device comprises an operating table; the characteristic is that the operating table is provided with a rotating shaft along the vertical direction, the side wall of the rotating shaft is connected with an elastic connecting rod, and the end of the elastic connecting rod is provided with a striking hammer,

[0008] Located outside the rotating shaft, a preset number of large circular card slots and small circular card slots are arranged in the form of a ring matrix, hollow cylinders of different materials are arranged in the large circular card slots and the small circular card slots by plugging, and the large circular card slots and the small circular card slots are arranged at unequal intervals;

[0009] The striking hammer can contact hollow cylinders of different materials and different diameters that are inserted into the large circular slot and the small circular slot.

[0010] Furthermore, the end of the rotating shaft is arranged on the output shaft of the motor through a key connection.

[0011] Furthermore, the elastic connecting rod is made of rubber or elastic steel.

[0012] Furthermore, a storage groove for placing the hollow cylinder is provided on the upper end surface of the operating table.

[0013] Furthermore, a safety baffle is fixedly provided on the upper end surface of the operating table between the large circular card slot and the small circular card slot, and a transparent top plate is detachably provided with the different safety baffles.

[0014] The beneficial effects of the utility model are:

[0015] One advantage of the utility model is that the percussion hammer, driven by an elastic connecting rod, acts on hollow cylinders of different sizes and made of different materials by directly percussion, thereby generating different sounds due to different materials and different sounds due to different hollow inner diameters.

[0016] One advantage of the utility model is that the large circular slots and the small circular slots are arranged at unequal intervals, which not only can obtain different sound intervals, but also produce different sound combinations. After the hammer naturally hits the first hollow cylinder, the elastic connecting rod is deformed, and the restoring force rapidly hits the second hollow cylinder, producing different sounds due to different impact intensity and speed.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] The specific implementation mode of the utility model: the combined audio sound-generating device comprises an operating table 1; the characteristic is that the operating table 1 is provided with a rotating shaft 3 along the vertical direction, the side wall of the rotating shaft 3 is connected with an elastic connecting rod 7, and the end of the elastic connecting rod 7 is provided with a striking hammer 8,

[0023] Located outside the rotating shaft 3, a preset number of large circular slots 6 and small circular slots 5 are arranged in the form of a ring matrix, and hollow cylinders 4 of different materials are arranged in the large circular slots 6 and the small circular slots 5 by plugging, and the large circular slots 6 and the small circular slots 5 are arranged at unequal intervals;

[0024] The striking hammer 8 can contact the hollow cylinders 4 of different materials and different diameters inserted into the large circular slot 6 and the small circular slot 5 .

[0025] Furthermore, the end of the rotating shaft 3 is arranged on the output shaft of the motor 10 through a key connection.

[0026] Furthermore, the elastic connecting rod 7 is made of rubber or elastic steel.

[0027] Furthermore, a storage slot 9 for placing the hollow cylinder 4 is provided on the upper end surface of the operating table 1 .

[0028] Furthermore, a safety baffle 2 is fixedly provided on the upper end surface of the operating table 1 between the large circular card slot 6 and the small circular card slot 5, and the safety baffle 2 is detachably provided with a transparent top plate.

[0029] It should be noted that the utility model is a combined audio sound-generating device. When working,

[0030] 1. The motor 10 drives the rotating shaft 3 to rotate, and the rotation of the rotating shaft 3 drives the elastic connecting rod 7 to move in a circle with the rotating shaft 3 as the axis.

[0031] 2. The hammer 8, driven by the elastic connecting rod 7, acts on the hollow cylinder 4 made of different materials by directly striking, thereby producing different sounds due to different materials.

[0032] At the same time, since the hollow cylinders 4 of the large circular card slot 6 and the small circular card slot 5 are different, different sounds are generated due to the different hollow inner diameters;

[0033] The large circular slots 6 and the small circular slots 5 are arranged at unequal intervals, which not only can obtain different intervals of sound and produce different sound combinations, but more importantly, the adjacent large circular slots 6 and small circular slots 5 can be very close to each other. After the hammer 8 naturally hits the first hollow cylinder 4, the elastic connecting rod 7 is deformed, and the restoring force rapidly hits the second hollow cylinder 4, producing different sounds due to different impact strengths and speeds.

[0034] The transparent top plate can be used to associate these different sounds with materials, sizes, impact speeds, impact intensities and combinations, which is more conducive to the understanding of the sound generation principles.

[0035] 3. The upper end surface of the operating table 1 is provided with a storage slot 9 for placing the hollow cylinder 4, which is convenient for placing different hollow cylinders 4.

[0036] Different safety baffles 2 are detachably provided with transparent top plates, which play a certain protective role and can avoid squeezing of hands under the premise of ensuring normal observation.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
