JPH0716991U - Acoustic vibration isolation end pin receiver for musical instruments - Google Patents

Abstract

(57) [Summary] [Purpose] To improve the sound quality of cello, double bass, etc. [Structure] Propagation of vibration is blocked by making point contact with the end pin.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to improving the sound quality of instruments such as a contrabass and cello with an end pin.

[0002]

[Prior art]

 Conventionally, there are three methods for playing an instrument attached to an end pin. 1. Stand the end pins as they are on the floor. 2. Cover the end pins with rubber and stand on the floor to prevent slipping. 3. Place a commercially available slip stopper for end pins on the floor, and stand the end pins on it. However, there was nothing considered to improve the sound quality, as the rubber of 2 and the anti-slip of 3 were both anti-slip.

[0003]

[Problems to be solved by the device]

 When playing an instrument with an endpin, the sound quality and tone of the instrument greatly depend on the condition of the floor where the endpin is set. The material of the floor is different depending on whether it is stone, wood, or plastic tile. above

It is not improved by any of the three methods mentioned in the prior art. In other words, the vibration of the musical instrument during performance is transmitted to the floor, and some of the acoustic energy emitted in the air is lost. At the same time, the vibration of the floor is transmitted to the musical instrument, which modulates the sound emitted by the musical instrument, resulting in muddyness and impaired sound quality. The present invention has been made in order to improve these drawbacks and enable a better performance without deteriorating the original sound quality and timbre of the musical instrument.

[0004]

[Means for Solving the Problems]

 The part that receives the end pin is mortar-shaped or bowl-shaped. The material is made of iron, brass, etc., which is hard and durable. The reason is that when the end pin is placed, the contact area is reduced and the propagation of vibration is blocked.

1.

2. The metal fitting for receiving the end pin is embedded in the lead block to absorb unnecessary vibration. The use of lead, which has a large specific gravity and is soft, gives an extremely large transmission loss, which is also very effective in isolating vibrations from the floor. Under the lead block, anti-vibration rubber, lead plate, and anti-slip rubber are layered to prevent vibration due to the difference in acoustic impedance. The present invention is an end pin receiver for a musical instrument having the above structure.

[0005]

[Action]

 According to the present invention, the musical instrument and the floor are separated from each other in terms of sound and vibration. The acoustic energy of a musical instrument can be emitted into the air without loss.

[0006]

【Example】

 Place the end pin receiver of the present invention on the floor. Set the instrument so that its end pin fits into the end pin receiver of the present invention and play.

[0007]

[Effect of device]

 With the structure as described above, the present plan can obtain a tone quality that is remarkably favorable as compared with the conventional musical instrument performance not based on the present plan, stably without being influenced by the condition of the floor.
