With reference to FIGS. 2 and 3, a schematic configuration of the bass generating section 2 and the vibration generating section 3, that is, the configuration of one bass generating and vibration generating unit 6 will be described.

The bass generator 2 is a bass generator that can reproduce sounds with low frequencies. As shown in FIG. 2, the bass generating section 2 includes a bass speaker unit 21 that mainly generates bass sounds, and a bass reflex type enclosure 22 that houses the bass speaker unit 21.

The bass speaker unit 21 is, for example, a loudspeaker unit used in a subwoofer or the like that reproduces low frequencies of about 200 Hz or less. Although not shown here, the bass speaker unit 21 is driven by an audio signal input via wire or wirelessly via an electric circuit such as an amplifier.

The bass reflex type enclosure 22 includes an enclosure portion having a hollow air chamber formed therein, and a duct having an open end for discharging bass sounds emitted from the bass speaker unit 21 to the outside.

In this embodiment, the bass reflex type enclosure 22 has a multi-stage structure including a plurality of enclosure parts 221 to 222 and a plurality of bass reflex ducts 223 to 224.

Specifically, as shown in FIGS. 2 and 3, the bass reflex type enclosure 22 includes a first enclosure part 221 in which the bass speaker unit 21 is housed in a first air chamber, and a first enclosure part 221 with one end connected to the first enclosure part 221. A first bass reflex duct 223 connected to the first bass reflex duct 223, a second enclosure part 222 connected to the other end of the first bass reflex duct 223, and an opening 224a connected to the second enclosure part 222 at the other end. It has a second bass reflex duct 224 facing the outside.

That is, in the present embodiment, the bass reflex type enclosure 22 has a two-stage structure in which a plurality of sets (two sets) of an enclosure portion having an air chamber and a bass reflex duct are arranged in series.

The first enclosure part 221 is formed of, for example, a hard synthetic resin or the like into a hollow substantially cylindrical shape having walls at both ends and having a circular cross section, and has a first air chamber having a relatively small volume inside the hollow part. is formed. The first enclosure section 221 is installed with the bass speaker unit 21 facing the first air chamber with its front (or back) facing the first air chamber, and has the bass speaker unit 21 fixed to a wall at one end.

Sound from the front (or back) of the bass speaker unit 21 is input into the first air chamber of the first enclosure section 221 . An opening is provided in the wall portion of the first enclosure section 221 to which the bass speaker unit 21 is fixed so that sound from the back (or front) of the bass speaker unit 21 can be radiated to the vibration generating section 3 side, which will be described later. ing.

The wall side of the first enclosure section 221 opposite to the end wall section to which the bass speaker unit 21 is fixed is formed in a substantially dome shape, and one end of the first bass reflex duct 223 is fixed thereto. Note that the material and shape of the first enclosure section 221 may be arbitrary.

The first bass reflex duct 223 is made of a cylindrical body with both ends open, and one end is connected to the first enclosure part 221 in an internal communication state. The first bass reflex duct 223 is arranged such that most of it is accommodated in the second air chamber of the second enclosure section 222.

The second enclosure section 222 is formed separately from the first enclosure section 221 in which the bass speaker unit 21 is built-in, and has a second air chamber that communicates with the first air chamber via the first bass reflex duct 223. is forming.

The second enclosure portion 222 is made of a flexible material such as sponge and has a substantially cylindrical shape. One end side of the second enclosure section 222 is connected to the first bass reflex duct 223 at a position close to the first enclosure section 221.

In this embodiment, the second enclosure part 222 has a diameter that is approximately the same as or slightly smaller than the diameter of the first enclosure part 221, and is provided long in the axial direction, so that the volume of the second air chamber is equal to the volume of the first air chamber. is set larger than . The length of the second enclosure section 222 is, for example, about 20 to 30 cm, and is installed vertically along the torso of the user. The second enclosure section 222 may vibrate due to changes in the sound pressure of the bass speaker unit 21 . Therefore, the bass generating section 2 is also configured to have a vibration generating function.

Since the second enclosure part 222 is made of a flexible material such as sponge as described above, it is placed along the user's torso and can be comfortably worn with almost no discomfort even when it comes into contact with the user's body. Furthermore, when the second enclosure part 222 comes into contact with the user's torso, the change in sound pressure in the second air chamber caused by the bass speaker unit 21 can be transmitted as vibration.

The second bass reflex duct 224 is made of a cylindrical body with openings at both ends, and is connected to the second enclosure part 222 in an internally communicating state, and has an opening 224a at one end exposed to the outside so that sound ( emit low-pitched sounds).

In this embodiment, most of the second bass reflex duct 224 is housed in the second air chamber of the second enclosure section 222, and one end of the second bass reflex duct 224 on the opening 224a side is exposed from the second enclosure section 222 to the outside. It is installed protrudingly.

In this embodiment, the bass reflex type enclosure 22 has a so-called double bass reflex type structure in which the enclosure portion and the bass reflex duct are configured in two stages. This makes it possible to obtain flat frequency characteristics.

The frequency of the bass sound from the bass reflex enclosure 22 and the frequency of vibration in the second enclosure section 222 can be selected by adjusting the resonance frequency determined by the opening area and length of the enclosure sections 221 and 222 and the bass reflex duct. .

For example, by selecting the resonant frequencies of the first and second bass reflex ducts 223 and 224, it is possible to prevent the occurrence of abnormal noise in the second enclosure section 222 or vibrations in a frequency band that feels uncomfortable or unnatural when touching the body. can be avoided.

In this embodiment, the volume of each enclosure part and the opening of the bass reflex duct are adjusted so that the low frequency sound from the open end of the second bass reflex duct 224 and the vibration generated in the second enclosure part 222 are, for example, about 40 to 120 Hz. Area and length are set.

The vibration generation section 3 is a vibration generation means that generates bodily-sensible vibrations using changes in sound pressure caused by the bass speaker unit 21. As shown in FIG. 2, the vibration generation section 3 includes a weight 31 that vibrates using the sound pressure of the sound emitted by the bass speaker unit 21.

In this embodiment, the vibration generation unit 3 has a bellows 32 that expands and contracts with a relatively large stroke due to changes in sound pressure from the back (or front) of the bass speaker unit 21, for example. A weight 31 is attached to one end. Therefore, when the weight 31 vibrates with the expansion and contraction of the bellows 32, the reaction force is transmitted to the user's body via the support means 4, and the user can feel the vibration as if being shaken. .

The vibration generation section 3 has a vibration enclosure section 33 containing a weight 31 and a bellows 32. The vibration enclosure section 33 is made of, for example, a hard synthetic resin and has a substantially cylindrical shape, and is integrally fixed to the end wall side of the first enclosure section 221.

The inner space of the vibration enclosure section 33 faces the back (or front) of the bass speaker unit 21 fixed to the end of the first enclosure section 221, and the sound pressure from the bass speaker unit 21 is transmitted to the vibration enclosure section. 33.

For example, the bellows 32 is housed inside the vibration enclosure part 33, and the end of the bellows is fixed to the end wall of the vibration enclosure part 33, so that the bellows 32 and the internal space of the vibration enclosure part 33 are connected to each other. The space between them is formed to be in a substantially sealed state. A weight 31 is fixed to the end of the bellows 32 on the inside side of the vibration enclosure portion 33 so as to close the end of the bellows, and the other end of the bellows is open to the outside.

As a result, when the sound pressure from the bass speaker unit 21 changes, the pressure in the space between the outside of the bellows 32 and the internal space of the vibration enclosure section 33 changes, causing the bellows 32 to expand and contract.

The weight 31 is made of metal, for example, and is a weight having an outer shape including a cylindrical portion so as to close one end of the bellows 32, and vibrates linearly inside the vibration enclosure part 33 as the bellows 32 expands and contracts. . For example, the weight 31 is supported via a damper 34 in order to vibrate stably and linearly. Note that in this embodiment, the frequency of vibration in the vibration generator 3 is set to, for example, about 20 to 40 Hz.

The support means 4 is a support means for supporting each element of the wearable speaker device such as the bass generating section 2, the vibration generating section 3, and the main speaker unit 5, and also functions as a means for attaching it to the user's body.

As shown in FIG. 1, FIG. 4, FIG. 5, and FIG. 6, the support means 4 is provided in a vest type or harness type as described above, and is made of a flexible sheet-like material such as leather or cloth and metal fittings.

A through hole is provided in the upper end wall of the cover 46, and the opening 224a of the second bass reflex duct is exposed to the outside through the through hole. Therefore, the opening 224a for emitting bass sound from the bass reflex type enclosure 22 is located near the upper chest and neck of the user wearing the bass reflex enclosure 22.

Furthermore, the cover 46 is formed with a bulging portion 46s, which is formed so that a portion of the upper side of the cover 46 is located near the upper chest of the user's torso and is curved in a convex shape toward the front. The main speaker unit 5 is supported by the bulging portion 46s of the cover 46. Note that the form of the cover 46 may be arbitrary.

The main speaker unit 5 is a speaker capable of reproducing sound in a wide range from low to high frequencies (for example, 200 to 20,000 Hz) that are within the human audible range. The main speaker unit 5 includes, for example, a conventionally known loudspeaker, and although not shown here, is driven by an audio signal input by wire or wirelessly via an electric circuit such as an amplifier.

Since the main speaker units 5 are arranged on the left and right sides, the left channel and the right channel may be reproduced separately.

In the present embodiment, the main speaker unit 5 has a speaker unit main body portion housed inside the bulging portion 46s of the cover 46 of the front portion 42 of the support means 4, and the front side from which the sound of the speaker is emitted is directed diagonally upward or downward. It is set towards the top. Therefore, the main speaker unit 5 and the bass speaker unit 21 are set at positions separated to some extent.

By arranging the main speaker unit 5 on the left and right upper chest sides of the torso in this way, the user can listen to the sound from the speakers well without covering his ears, and also improves the bass sound generation described above. The bass sound from the opening 224a of the second bass reflex duct of section 2 can be heard. Furthermore, by covering the back sides of the bass generating and vibration generating unit 6 and the main speaker unit 5 with the cover 46, the overall appearance and design of the device can be improved.
