Description

Technical Field

[0001] The utility model relates to the technical field of music auxiliary components, in particular to a high-frequency vibration bridge of an erhu. Background Art

[0002] Erhu opening refers to the phenomenon that the sound of a new erhu gradually changes and the sound quality improves during long-term playing. The skin of a new erhu is relatively stiff, and the sound it produces may be dry and sharp. As the number of times it is played increases, the skin will gradually become soft and elastic, and the sound will change accordingly, from sharp to soft, then to thick, and finally to a little muffled. During this process, the various parts of the erhu, such as the skin, bridge, and strings, reach a better coordination state through vibration running-in. The opening process is also the process in which the sound style of the erhu is gradually finalized. Once it reaches a stable state, its sound characteristics will not change much.

[0003] However, the erhu sold nowadays are all in an untuned state, and it takes the buyer about two years to tune them up. The tuning process is very long, so we proposed the erhu high-frequency vibration bridge. Utility Model Content

[0004] The purpose of the utility model is to provide a high-frequency vibration bridge for an erhu to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: an erhu high-frequency vibration bridge comprises a shell and a vibration base; a vibration base is arranged at the bottom of the shell, a sound cavity is opened inside the vibration base, a high-frequency vibrator is arranged in the sound cavity, and a vibrator shell is arranged at the rear end of the high-frequency vibrator;

[0006] The vibrator shell extends backwards, a terminal protection shell is arranged at the rear end of the inner cavity of the vibrator shell, and a terminal is arranged at the rear end of the terminal protection shell.

[0007] Preferably, a symmetrical string installation opening is provided on the top of the shell, the edges of the string installation opening are all obtuse, and strings are installed in the string installation opening.

[0008] Preferably, there are two left and right binding posts, and the ends of the two binding posts are respectively connected to power transmission lines.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The bridge transmits the vibration of the strings to the sound box, causing the sound box to resonate and produce sound; when the vibration generated by the strings is transmitted to the sound cavity and resonates with the high-frequency vibrator, the frequency of the sound and the amplitude of the string vibration are increased; the high-frequency vibration bridge of this scheme can make the erhu reach a fully opened state in 5-10 days, making the erhu's tone full and the range wide, so that the erhu's tone is perfect and reaches the qualified state of the finished product; it solves the problems of the erhu's slow opening and the erhu's sharp sound and narrow range when it is not opened.

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0017] Example:

[0018] See also Figure 1-3 The utility model provides a technical solution for high-frequency vibration bridge of Erhu: comprising a housing 1 and a vibration base 2;

[0019] A vibration base 2 is provided at the bottom of the housing 1, a sound cavity 7 is provided inside the vibration base 2, a high-frequency vibrator 8 is provided in the sound cavity 7, and a vibrator shell 6 is provided at the rear end of the high-frequency vibrator 8;

[0020] The vibrator shell 6 extends backward, and a terminal protection shell 5 is provided at the rear end of the inner cavity of the vibrator shell 6. A terminal 9 is provided at the rear end of the terminal protection shell 5. There are two left and right terminals 9, and the ends of the two terminals 9 are respectively connected to the power transmission line 4; the top of the shell 1 is provided with symmetrical string installation openings 3, and the edges of the string installation openings 3 are all obtuse. The string installation openings 3 correspond to the two strings of the erhu, and the obtuse edges can reduce the wear on the strings;

[0021] When using this solution, ensure that the strings are not stretched tight; when installing or removing the erhu bridge, first ensure that the strings are loose, so as to avoid scratching the instrument skin when moving the bridge; use the left thumb to gently lift the strings from bottom to top, and the lifting height should be equal to or slightly higher than the height of the bridge; align the string installation opening 3 of the bridge with the string, and then push it from one side to the center of the instrument skin or the best pronunciation point tested by yourself; after the bridge is correctly placed, release the left thumb;

[0022] Then the power supply is connected to the transmission line 4, so that the high-frequency vibrator starts working. When the vibration generated by the strings is transmitted to the sound cavity 7 and resonates with the high-frequency vibrator 8, the frequency of the piano sound and the amplitude of the string vibration are increased. The high-frequency vibrator 8 is mainly composed of a generator, an oscillator and a transducer, and completes the vibration by converting electrical energy into mechanical energy. When current passes through the oscillation tube, high-frequency electric and magnetic fields are generated, so that the transistor is continuously switched on and off, converting electrical energy into high-frequency vibration energy. The action of the high-frequency vibrator can increase the resonance amplitude of the strings and improve the sound-opening efficiency.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description. Therefore, it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model, and any figure marks in the claims should not be regarded as limiting the claims involved.
