DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sound improving member for a speaker for improving the sound reproducibility of a speaker used for an audio equipment or the like, and to a dynamic cone speaker and a speaker using the same.

[0002]

2. Description of the Related Art There are various types of speakers, and the most common one used for audio equipment such as a stereo is a so-called dynamic cone speaker. The dynamic cone speaker is equipped with a conical vibrator and a casing-mounted moving coil provided in the center of the rear part, and converts the audio current into the front-back vibration of the moving coil, thereby causing the vibrator to vibrate. To generate sound.

[0003] In order to reduce the noise of the speaker of this type and improve the sound reproducibility, various means such as firmly fixing a moving coil casing to a speaker cabinet have been taken. However, the conventional methods described above are not enough to improve the sound of the speaker, and when high-quality sound is required, expensive and high-quality components must be used for each component of the speaker. Instead, this led to higher prices for the product.

[0004]

The object of the present invention is to solve the above problems,
It is an object of the present invention to provide a speaker having high-quality sound reproducibility at a low cost and to improve the sound reproducibility of an existing speaker by a simple improvement.

[0005]

Means for Achieving the Object Means of the present invention taken to achieve the above object are as follows.

The first means is substantially plate-shaped,
It is a sound improving member for a speaker, which is formed so as to be attachable to a rear surface of a moving coil casing of a dynamic cone speaker, and is made of a hacaranda material.

The second means is substantially plate-shaped,
The sound-improving member for a speaker, which is formed so as to be attachable to a rear surface of a moving coil casing of a dynamic cone speaker and is made of a Pasalt material.

[0008] In the third means, substantially plate-shaped,
The sound-improving member for the speaker is formed so as to be attachable to the rear surface of the moving coil casing of the dynamic cone speaker and is made of German pine.

The fourth means is substantially plate-shaped,
It is an acoustic improvement member for a speaker, which is formed so as to be attachable to a rear surface of a moving coil casing of a dynamic cone speaker and is made of ebony material.

The fifth means is substantially plate-shaped,
It is an acoustic improvement member for a speaker which is formed so as to be attachable to a rear surface of a moving coil casing of a dynamic cone speaker and is made of a rosewood material.

In the sixth means, a dome-shaped projection is provided on one surface of the speaker sound improving member.
A sound improving member for a speaker according to any one of the first to fifth means.

In the seventh means, the first to the sixth means
A dynamic cone speaker in which the speaker sound improving member according to any one of the means is attached to a rear surface of a moving coil casing.

The eighth means is a speaker provided with a required number of dynamic cone speakers according to the seventh means.

The speaker according to the present invention has a structure in which a dynamic cone speaker such as a woofer, a squawker, or a tweeter is attached to a speaker cabinet.

[0015]

If the sound improving member for a speaker made of each of the above-mentioned materials is attached to the rear surface of the moving coil casing of the dynamic cone speaker, the sound reproducibility of the speaker is improved, although the reason is not clear. High quality sound can be reproduced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is a perspective view showing an embodiment of a speaker sound improving member according to the present invention, and FIG. 2 is an explanatory view showing a cross section of a speaker cabinet according to the present invention. The sound improving member 1 for a speaker is formed in a disc shape from a wood material such as a hacaranda material. Acoustic improvement member for speaker 1
Has a diameter of 60 mm and a thickness of 7 in this embodiment.
mm. The speaker sound improving member 1 is attached to the rear surface of the moving coil casing 30 of the woofer 3 which is a dynamic cone speaker attached to the cabinet 2 of the speaker S with an adhesive (see FIG. 2).

A sound improving member 1a for a speaker, which is formed in accordance with the size of the moving coil casing 40 of the squawker 4, which is also a dynamic cone speaker, is adhered. On the rear surface of the moving coil casing 50 of the tweeter 5, a speaker sound improving member 1b formed according to its size is adhered. The speaker sound improving members 1, 1 a, 1 b are formed so that only the diameter matches the diameter of each moving coil casing, but the length is the same.

(Operation) FIG. 3 is a table showing the results of trial listening of the speaker according to the present invention. The operation of the present embodiment will be described with reference to FIGS. Dynamic cone speakers Woofer 3, Squawker 4,
Moving coil casing 30, 4 of tweeter 5
A speaker in which nothing is attached to conventional speakers 0 and 50, and a speaker in which the sound improving members 1, 1a and 1b for speakers are attached to the back of the moving coil casings 30, 40 and 50 of the woofer 3, squawker 4 and tweeter 5 of the same speaker. I compared with S.

As a result, as can be seen from FIG. 3, all of the listeners A to G have the speaker sound improving members 1, 1a,
It was determined that the speaker S to which 1b was attached had better sound reproducibility. At this time, the reason for this is not clear, but by attaching the speaker sound improving members 1, 1a, 1b to the rear surface of the moving coil casings 30, 40, 50, magnetic fluctuations generated inside the casings are affected by, for example, vibration suppression action. Has some effect, such as
As a result, it is considered that the sound reproducibility of each speaker of the woofer 3, the squawker 4, and the tweeter 5 was improved, and high-quality sound that could not be obtained conventionally can be reproduced.

FIG. 4 is a sectional view showing another embodiment of the sound improving member for a speaker according to the present invention. The speaker acoustic improvement member 1c of the present embodiment has a structure in which a dome-shaped protrusion 10 is provided at the center of one surface. The shape of the protrusion 10 is substantially the same as the shape of a diaphragm (dome-shaped diaphragm, not shown) provided at the center of a woofer, squawker, tweeter, or the like to be attached.
According to this, although the reason is not clear, even better sound reproducibility was obtained as compared with the speaker S using the above-described speaker sound improving members 1, 1a, and 1b. It should be noted that the present invention is not limited to the illustrated embodiment,
Various modifications are possible within the scope of the claims.

[0021]

The present invention has the above configuration and has the following effects. (A) If the sound-improving member for the speaker made of Jacaranda, Pasarongt, German pine, ebony, and rosewood is attached to the rear surface of the moving coil casing of the dynamic cone speaker, the sound of the speaker is not clear. Reproducibility is improved, and high-quality sound that could not be obtained conventionally can be reproduced.

(B) Since the acoustic improvement member for a speaker of the present invention is made of wood, it is inexpensive, and a speaker having excellent sound reproducibility can be provided at a low cost without particularly using high quality and expensive parts.

(C) According to the present invention, the sound reproducibility of an existing speaker can be improved by a simple improvement of attaching a speaker sound improving member to the rear surface of the moving coil casing.

(D) The sound improving member for a speaker provided with a dome-shaped protruding portion at the center of one surface is not clearly understood, but is compared with a sound improving member for a speaker having no protruding portion. As a result, better sound reproducibility was obtained.
