Description

Adjustable sound type frame drum

Technical Field

The invention relates to a frame drum.

Background

The box drum is one of the most common instruments in the world. It is a shallow drum, usually with a large striking face. It is the oldest instrument in the world, and has been around the world for centuries.

The existing frame drum can generate sensitive reaction to humidity and cold and heat due to the property of the drum head, for example, the larger the humidity is, the looser the drum head is, and the lower the pitch of the drum is. In the process of playing, a proper pitch needs to be selected according to the style attribute of music, if the drum head is too loose, the playing requirement is not met, and in order to deal with the change, a frame drum capable of tuning high is highly needed.

In order to solve the technical problem, the technical solution of the toneable drum rim of the invention is as follows:

comprises a drum ring, a drum head fixed on the drum ring and an inflatable annular air bag for adjusting the tightness of the drum head; the annular air bag is fixed between the annular air bag and the drum head.

The annular air bag is connected with an inflation valve used for inflating or deflating the annular air bag.

The outer end of the inflation valve is penetrated to the inner side of the drum ring.

The lower part of the drum skin is adhered to the drum ring and is reinforced by nails.

A decorative rope is bonded on the outer side below the drum skin; the decorative cord covers the nail.

A decorative belt is further bonded below the drum ring; the decorative strip is positioned below the decorative rope.

An arc-shaped groove is formed below the drum ring.

The upper end and the lower end of the drum ring are respectively provided with a chamfer.

The drum skin is made of animal hide.

The invention can achieve the technical effects that: the invention inflates the annular air bag to ensure that the annular air bag is uniformly expanded, the drum head is uniformly stressed to be expanded, the tension of the drum surface of the drum head is increased, the pitch is increased, and conversely, the annular air bag is deflated, and the pitch is decreased.

Detailed Description

The invention is explained in further detail below with reference to the drawings.

See fig. 1-5.

A sound-adjustable frame drum comprises a drum ring 1, a drum head 2 fixed on the drum ring 1, and an inflatable annular air bag 3 for adjusting the tightness of the drum head 2; the annular air bag 3 is fixed between the annular air bag 3 and the drum head 2.

Specifically, the annular air bag 3 is connected with an inflation valve 4 for inflating or deflating the annular air bag.

Specifically, the outer end of the inflation valve 4 penetrates the inner side of the drum ring 1.

Specifically, the lower part of the drum head 2 is adhered to the drum ring 1 and is reinforced by nails 5.

Specifically, a decorative rope 6 is bonded on the outer side below the drum head 2; the decorative cord 6 covers the nail 5.

Specifically, a decorative belt 7 is further bonded below the drum ring 1; the decorative strip 7 is positioned below the decorative cord 6.

Specifically, an arc-shaped groove 8 is formed below the drum ring 1.

Specifically, chamfers 9 are respectively arranged at the upper end and the lower end of the drum ring 1.

In particular, the drum skin 2 is made of animal hide.

The specific description is as follows: the annular air bag 3 is attached to the surface of the drum ring 1, the inflation valve 4 faces the inner side of the drum ring 1, and the drum head 2 covers the annular air bag 3 and the drum ring 1 simultaneously during covering. After the drum head 2 is fixed well and stable, the annular air bag 3 is uniformly expanded by inflating the inflation valve 4, the drum head 2 is uniformly stressed to be expanded, the tension of the drum head surface of the drum head 2 is increased, the pitch is increased, otherwise, the annular air bag 3 is deflated through the inflation valve 4, the tension of the drum head 2 is decreased, and the pitch is decreased.

The drum ring 1 is preferably made of birch wood, the birch wood is high in density and hardness, and can be used as a musical instrument material to have strong cavity support and sound reflection, so that excellent solid drum sound is generated. Chamfering processes are respectively carried out on two sides of the drum ring 1, specifically, chamfers 9 are respectively arranged at the upper end and the lower end of the drum ring 1, an arc-shaped groove 8 is formed on one side of the drum, which is in contact with the wrist of an arm, and chamfering processes are also carried out on the periphery of the arc-shaped groove 8, so that the chamfers improve the comfort level of mastering musical instruments; the arc-shaped groove 8 cuts the drum cavity which enables the arm and the wrist to be better attached to the drum ring 1, brings comfort and simultaneously provides more space for the wrist to touch the drum surface of the drum head 2. The side of the drum in contact with the drum head 2 is chamfered by a 45-degree bevel angle, and the process can lead the sound of the drum head to gather towards the central point and simultaneously generate more lasting delay and overtone, thus leading the drum sound to have more penetrating power and benign resonance. The surface of the drum ring 1 is adhered with color paste, varnish and wood wax oil, the coloring is beautiful, and the varnish wood wax oil is used for sealing pores of a wooden material, so that the wooden structure is more stable and is less affected by external environment such as humidity, thermal expansion and cold contraction as far as possible.

The drum skin 2 is preferably selected from animal hide, and commonly used deer skin is Corii Bubali and Corii equi Asini. The hide has natural elasticity and tension, and can produce better drum skin resonance and harsher sound compared with some technical skins and resin skins. When skin covering is carried out, the hide must be soaked in advance, so that the hide is fully stretched and recovered to be elastic, and then skin covering technology is carried out. Covering the skin: a perfect circle which is 10 centimeters larger than the diameter of the drum ring is taken from the center of the hide, holes are formed every thirty degrees, the hide is covered on the drum ring 1 with the 45-degree chamfer angle, a rope penetrates through 12 holes and then is fixed in a circular fixing device, 12 positioning points in the fixing device correspond to the 12 positioning points, the drum ring 1 is supported by a jack, and the rope is uniform to tighten the drum hide 2. How to fix the drum head 2: firstly, glue is smeared 504 in the drum ring 1, and then the iron wire is used for enclosing and fastening the joint of the drum head 2 and the drum ring 1 to ensure that the glue is thoroughly contacted with the drum head 2 of the drum ring 1. And then a circle of nails 5 (the nails 5 are small copper nails) are punched below the annular air bag 3 for fixing the drum head 2 and anchoring the drum head 2, so that the drum head 2 still keeps the original uniform tension when being stretched, and the condition that the pitch of the drum surface of the drum head 2 is not uniform due to the displacement of the drum head 2 or the uneven tension on one side is avoided. After the nail 5 is nailed, a circle of decorative rope 6 (the decorative rope 6 is a nylon rope) with the width of 1 cm and the diameter of 3 mm is covered and tied at the same position, the effect of covering the trace of the nail 5 is achieved, the contact area of the drum head 2 and the drum ring 1 is enlarged, and the drum head 2 is fixed better. Nail 5 plays the effect of anchor point, decorates rope 6 and ferret 7 and plays the effect of beautifying and consolidating firm drum head 2, and the drumhead of drum head 2 is fixed more firm, just can make the state of drum more stable, and the drum sound is more even, reduces the harm of external influence to the drum.
