Description

[Detailed explanation of the idea] Technical field The present invention relates to soundware.

BACKGROUND TECHNOLOGY When trying to listen to a musical performance while driving a motorcycle or motorized bicycle,
Because he wears a helmet, he cannot use headphones, making it difficult to enjoy music at a sufficient volume. To make this possible, recently, clothing, ie, soundwear, which has a speaker system installed in a position corresponding to the driver's shoulder has been developed and used. 1 to 3 show vests generally developed as soundware. This vest is manufactured with due consideration given to functionality, safety, and weather resistance as rider wear.

As shown in FIGS. 1 and 3, the vest 1 is sewn from a cloth-like material including an outer fabric 2 and a lining fabric 3. Preferably, cotton or feathers are inserted between the outer fabric 2 and the lining fabric. etc. (not shown).
A pair of left and right circular openings 2a are formed in the outer cloth 2 at positions corresponding to the shoulders of the vest 1. Outer cloth 2
A bowl-shaped member 5 is arranged between and the backing cloth 3 so that its open end face faces the opening 2a. Further, in the bowl-shaped member 5, the sound emitting surface is located at the opening 2a.
A speaker unit 6 is fixedly installed so as to face the speaker. Note that the speaker unit 6 has a vibrating section 6a.
and a magnetic circuit section 6b, and since this structure is well known, it will not be described in detail here. Further, a lead wire 7b is connected to a voice coil (not shown) which is a component of the vibrating section 6a via a drawer relay member 7a.
The lead wire 7b is attached to the back side of the outer fabric 2 via a plurality of magic fasteners 7c, and
The receiver is connected to a small tape recorder (not shown) or a small radio (not shown) placed at a predetermined location. Moreover, on the open end surface of the bowl-shaped member 5,
A protective net 8 is arranged to protect the vibrating section 6a of the speaker unit 6. Outer fabric 2 and lining fabric 3
A fixing cloth 9 made of a woven fabric is also provided between the bowl-shaped member 5 to cover the portion other than the open end surface and to fix the bowl-shaped member to the outer cloth 2.

As is particularly clear in FIG. 3, a plurality of ventilation holes 5a are formed in the bottom of the bowl-shaped member 5 and extend radially around the center of the main surface of the bottom. Further, a plurality of ventilation holes 9a are formed in the fixing cloth 9 in correspondence with the ventilation holes 5a. These ventilation holes 5a and 9a are provided to release back pressure generated when the vibrating section 6a of the speaker unit 6 vibrates.

It is well known that in order to obtain desired bass characteristics in a speaker system, the volume of the rear space of the speaker unit must be greater than a predetermined amount. However, when the vest is worn, the ventilation holes 9a are closed by the lining fabric 3. Moreover, when the user moves the body while wearing the bowl-shaped member 5, the bowl-shaped member 5 moves slightly within the fixed cloth 9.
Furthermore, the ventilation hole 5a may also be blocked by the fixing cloth 9. If the ventilation holes 5a and 9a are blocked in this way, the volume obtained is considerably smaller than the required volume of the rear space, and the vibrating section 6a becomes difficult to move due to the acoustic load, and the sound pressure level in the low frequency range decreases. Significant attenuation compared to the level required for satisfactory music reproduction.

Summary of the invention The present invention has been made in view of the above points, and its purpose is to provide soundware having good acoustic characteristics.

The soundware according to the present invention includes a plurality of ventilation holes formed in the bottom of the bowl-shaped member and extending radially from the center of the main surface of the bottom, and a plurality of ventilation holes formed in the side of the bowl-shaped member. The present invention is characterized in that at least the portion of the fixing cloth that is fixed to the outer cloth, which faces the ventilation holes, is permeable to sound pressure, thereby increasing the volume of the rear space of the vibrating section of the speaker unit.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to FIGS. 4 to 9.

FIGS. 4 and 5 show the main parts of the soundware according to the first embodiment of the present invention. The soundware is in its best form.

In FIG. 4, a bowl-shaped member 5 in which a speaker unit 6 is housed is made of resin or the like.
A plurality of ventilation holes 5b are formed in the bottom of the bowl-shaped member 5 and extend radially around the center of the main surface of the bottom. As is clear from FIG. 5, the ventilation hole 5b is formed to reach the side of the bowl-shaped member 5. Further, the fixing cloth 11 which covers the portion of the bowl-shaped member 5 other than the open end surface and which fixes the bowl-shaped member to the outer cloth 2 is a mesh cloth having sound pressure permeability, that is, high air permeability. In this way, the radial ventilation hole 5b formed at the bottom of the bowl-shaped member 5 is made to reach the side of the bowl-shaped member, and the mesh cloth is used as a fixing cloth for fixing the bowl-shaped member 5 to the outer cloth 2. By using this, the space 12 on the peripheral side of the bowl-shaped member 5 can also be used as the back space volume of the speaker unit 6. Note that the above-mentioned sound pressure permeability may be achieved only in the portion facing the ventilation hole 5b.

Therefore, even if the lining fabric 3 is in close contact with the bottom of the bowl-shaped member 5 when the sound wear is worn, a sufficient volume of the space on the back side can be obtained, and as a result, the speaker system is arranged as shown in the solid line in FIG. 12a
It has a frequency characteristic shown by . The frequency characteristics shown by the broken line 12b in FIG. 6 are those of the speaker systems shown in FIGS. 1 to 3, but the bass characteristics are significantly improved in the speaker system built into the soundware of the present application. It is clear that

In the description of this embodiment, the same reference numerals are used for parts that are the same as or correspond to those of the soundware shown in Figs. 1 to 3, and parts other than the above are constructed in exactly the same way as the soundware. I will not go into details. The same applies to the embodiments described below. Furthermore, the term cloth here refers to a thin and flat material made of synthetic resin or other material.

FIGS. 7 and 9 show the main parts of soundware which is a second embodiment of the present invention.

In the figure, a plurality of ventilation holes 5b are formed in the bottom of the bowl-shaped member 5, extending radially from the center of the main surface of the bottom, and reaching the sides of the bowl-shaped member. The bowl-shaped member 5 also has a ventilation hole 5.
A plurality of ribs 5c are formed extending from the bottom portion to the side portions between the portions a. The portion of the bowl-shaped member 5 other than the open end surface is covered with a fixing cloth 11 made of a mesh cloth that fixes the bowl-shaped member to the outer cloth 2.

By providing the ribs 5c, the lining cloth 3 will not come into close contact with the bottom of the bowl-shaped member 5 when the sound wear is worn. Also, rib 5c
Since the outer fabric 2 and the inner fabric 3 in the vicinity of the rib 5c are provided so as to reach the side of the bowl-shaped member 5,
Even when wearing clothing, they are prevented from coming into close contact with each other to a considerable extent, and the volume of the rear space of the speaker unit 6 is kept large.
Therefore, the bass characteristics become better.

Effects As detailed above, in the soundware according to the present invention, a plurality of ventilation holes are formed at the bottom of the bowl-shaped member and extend radially from the center of the main surface of the bottom. At least the portion of the fixing cloth that fixes the bowl-shaped member to the outer cloth, which faces the ventilation hole, passes through the sound pressure. Therefore, when the wearer is wearing the wearer, the space at the rear of the speaker unit can be kept large, and good acoustic characteristics can be obtained.

Further, in the soundware according to the present invention, a rib is formed on the bowl-shaped member, extending from the bottom to the side between the ventilation holes. That is, the lining fabric does not come into close contact with the bottom of the bowl-shaped member when the garment is worn, and the outer fabric and lining fabric near the ribs are prevented from coming into close contact with each other over a wide range when the garment is worn. Therefore, the rear space of the speaker unit can be made larger, and even better bass characteristics can be obtained.
