AI Technical Summary

Technical Problem

Conventional methods for reducing speaker vibrations in electronic musical instruments are inadequate, leading to noise emission and structural issues, and fail to protect the speaker effectively.

Method used

A speaker cabinet is designed with a divided upper and lower part connected by a shock-absorbing material, supported by a member, and incorporates vibration-absorbing materials with specific shapes and elastic properties to minimize vibration transmission.

Benefits of technology

The cabinet effectively absorbs external vibrations and protects the speaker, preventing noise emission and structural damage during performance.

Abstract

To provide a speaker storage cabinet that can be built into an electronic musical instrument and has a seismic isolation structure. [Solution] The speaker storage cabinet comprises an upper part 1 that contacts the electronic musical instrument, a bottom part 4 that provides a support for the speaker body, and shock absorbing material 3 that connects them together, and provides seismic isolation to prevent vibrations from the electronic musical instrument from being transmitted to the speaker and its transmission board.

Description

[Technical field]

[0001] This invention relates to a speaker cabinet for use in an electronic musical instrument. [Background technology]

[0002] Conventionally, when an electronic guitar has a built-in speaker / amplifier, turning up the volume on the speaker causes the speaker to vibrate, and the vibration is then transmitted to the surrounding housing, causing the strings and pickup to vibrate as well. This vibration is then converted into an electrical signal, which is then emitted from the speaker, resulting in feedback.

[0003] Known solutions to this problem include placing a cushioning material (such as sponge) between the electronic instrument and the speaker, placing the speaker with a space between it and the electronic instrument itself, or setting an upper limit on the speaker volume. However, these solutions have not been able to completely solve the problem, as they impose design restrictions or reduce product functionality. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] US3357291A Summary of the Invention [Problem to be solved by the invention]

[0005] However, conventional methods such as wrapping the speaker in shock-absorbing material or sandwiching it between the speaker and the main body do not adequately absorb vibrations and cannot completely prevent noise.

[0006] In addition, it does not contribute much to protecting the speaker itself, and any impact to the electronic instrument is transmitted directly to the speaker, meaning it cannot address structural problems that may occur while playing the instrument. [Means for solving the problem]

[0007] In order to solve the above problems, the present invention provides a cabinet containing a speaker, the cabinet being divided into an upper part and a bottom part, and the upper part of the cabinet and the bottom part of the cabinet being connected by a shock-absorbing material made of an elastic material or the like.

[0008] In this speaker cabinet, the shock absorbing material connecting the top and bottom of the cabinet is preferably supported by a support member.

[0009] In this speaker cabinet, it is preferable that the cabinet bottom is formed in a shape that holds the speaker to be used. In this case, in order to make the speaker and the cabinet bottom less susceptible to the effects of vibration, it is preferable that only the holding member comes into contact with the speaker and that a small member that easily absorbs vibration is used.

[0010] It is preferable that the holding member has the strength to hold the cabinet bottom and is made of a material and has a shape that absorbs vibrations.

[0011] In this speaker cabinet, two elastic materials are installed as a set on the protrusions formed on the side of the bottom of the cabinet, and a circular or rectangular vibration absorbing material with holes is suitable as a holding and cushioning material that can be fixed by the support member without using adhesives or screws. Effect of the Invention

[0012] The speaker cabinet of the present invention has a seismic isolation structure that uses elastic materials in the cabinet with the speaker built in. It is effective in absorbing external vibrations regardless of the type or size of the speaker, and is also suitable for protecting the speaker. [Brief description of the drawings]
