JPS5894652A - Vibration and resonance preventing device exclusive for legs of acoustic instrument - Google Patents

Abstract

PURPOSE:To prevent the transmission of the vibration and the resonance caused by the acoustic instruments to the other instruments by a method wherein a steel ball body is arranged between the upper and lower disc like plate bodies to make them contact in a point contact while both of them are integrated by a plurality of balance springs. CONSTITUTION:Steel dishes 2, 2' are arranged in the upper disc-like plate body 1, attached to the hole of the bottom plate for the acoustic instrument, and the lower disc-like plate body 4, arranged below the upper plate body 1 while a steel ball body 3, having high strength and accuracy is provided at the center thereof as the contacting points of the upper and lower plate bodies 1, 4. A plurality of balance springs 5 are provided around the outer periphery thereof, surrounding the steel ball body 3 and the steel dishes 2, 2' so as to integrate both of the plate bodies 1, 4. Further, the upper disc-like plate body 1 is enclosed by an upper special rubber cover 6 while the lower disc-like plate body 4 is enclosed by a lower special rubber cover 6' for shielding the vibration and the resonance.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a combination and leg-specific device that prevents transmission of vibration resonance caused by various sound '11 devices to other devices and disperses and absorbs it.

The purpose of the present invention is to provide a combination device and a dedicated leg device that can prevent the vibration resonance of each audio device from being transmitted to others, improve the accuracy of each audio device itself, and prevent any nuisance to others. It is.

An example of this invention as a leg-specific device for preventing vibration resonance caused by each sound i11 device will be described below with reference to the drawings.

For each audio device itself■, drill a circular hole in the bottom plate,
This is a special device for legs that is formed as a conical body and attached to the hole in the bottom plate of No. 7, and the circular plate with a threaded upper cylinder [F] is screwed into the hole in the bottom of the Tani Takasho equipment, and the lower circular plate is attached. body ■
#I, and inside it, there are copper plates @-■ on the top and bottom that are strong enough to withstand Tani Otochi equipment, and in the center, there are steel balls with high strength and precision ■ on the upper legs and lower body. A circular plate with an upper cylinder that connects the upper and lower bodies with multiple balance springs on the outer periphery surrounding the upper and lower copper plates serving as connection points and the upper and lower copper plates. ■The outer periphery is surrounded by a hakama-style upper part special rubber cover■, and the lower body has a circular plate body■,
In combination with vibration resonance isolation, a special lower rubber cover C with a rising collar is formed around the outer periphery of the lower body to harmonize with the upper body, and serves as a vibration co-loss prevention device for the legs of each audio equipment. .

A vibration resonance prevention device dedicated to the legs of each audio device according to the present invention will be described.

Transmission of vibration resonance by each sound alarm device to others is prevented by attaching a dedicated leg device to each sound alarm device itself.

Vibration from each sound 11m11 device is transmitted to the circular plate body with an upper cylinder (■), but for exclusive use of the legs, the contacting cone is divided into two parts, and a steel sphere (■) with a minimum area of continuous transmission through point contact in the center is used. , point contact with minimum vibration transmissibility,
The vibrational resonance is minutely dispersed from the steel sphere (1) into the atmosphere, which is the intermediate layer, and the vibrational resonance is reduced and transmitted to the lower circular plate (2).

In addition, a balance spring ■ is used to integrate the upper circular plate body with a cylinder ■ and a lower circular plate body ■, and the vibration resonance from the upper and lower parts is suppressed by the special rubber on the upper and lower parts. Cover■−■In the atmosphere, which is the internal intermediate layer,
The vibration resonance is transmitted to the balance spring ■, but due to the minute vibration of the balance spring ■, the vibration resonance is dispersed and absorbed into the atmosphere.
The full length of the balance spring (■) exerts a dispersion limiting effect, and the special rubber cover (■) surrounding the lower circular plate (■) further blocks vibration resonance transmission.

The configuration and effects of the present invention have been explained above, but specifically, it is almost impossible to prevent vibration resonance by using conventional convex rubber legs on the main bodies of audio equipment such as amplifiers and players. It is said that this is a rare occurrence, and although something called the I/7 Urator is now installed, it is said to be a safety measure and cannot be prevented and is said to be rare.

According to the present invention, the vibration resonance prevention device for each O-leg of the audio equipment is directly attached to the amplifier, player, and speaker box, which are sound equipment, in order to prevent the transmission of vibration resonance. This is a vibration resonance prevention device exclusively for the legs of audio equipment that can fully demonstrate its further enhanced functionality as a device that also uses high-performance legs, as it can prevent vibration resonance from other sources such as the life of the casing.
