Description

[Detailed explanation of the invention] This invention provides a deep bass signal directly to the body, making it feel as if the acoustic energy from the sound source (vibration unit) is transmitting through the air and causing the body to vibrate. The present invention relates to a vibration transmission mechanism of a realistic sensation reproduction device that utilizes a realistic sensation reproduction effect.

First, a conventional vibration transmission mechanism will be explained based on FIGS. 1 to 3. In the figure, A indicates a chair frame, B indicates a canvas wrapped around the back of the chair frame A, and C indicates a canvas wrapped around the seat. A vibrating frame D is attached to the front surface of the canvas B.
is integrally fixed with a stay E and a screw F on the rear side via a canvas B. A vibration unit G is fixed to the stay E. H is the canvas wrapped around the vibrating frame D, I is the chair frame A
2 shows a cushion to be applied to the garment.

Next, the operation of the above conventional example will be explained. When the vibration unit G vibrates, due to inertial force, the vibration is transmitted through the stay E and vibrates the vibration frame D, giving vibration to the sitting human body via the cushion, thereby reproducing a sense of reality. .

However, in the conventional vibration transmission mechanism described above, only the vibration frame D is configured to apply vibration to the human body, so the vibration frame must be made larger in order to transmit vibration to the entire human body, which increases the weight. There was a drawback that the inertial force efficiency of the vibration unit G was reduced, and the vibrations through the cushion I were not sufficiently transmitted to the human body. In particular, due to the decrease in inertial force efficiency, variations in the material, hardness, etc. of the cushion I have the disadvantage that variations in the vibrations directly transmitted to the human body occur.

The present invention aims to solve the above-mentioned drawbacks, and is a vibration immersion reproduction device that can efficiently transmit vibrations to the entire human body based on Pascal's principle using a sealed liquid or gas as the vibration medium of the vibration unit. The purpose is to provide a transmission mechanism.

Hereinafter, the present invention will be explained in detail based on the embodiments shown in the drawings. FIG. 4 is a sectional view of the chair frame and cushion in an exploded state, and FIG. 5 is a perspective view thereof. 1 is a chair frame; 2 is a canvas wrapped around the back of the chair frame 1; a circular hole 3 is formed in the center of the canvas 2; A canvas 4 is also wrapped around the seat of the chair frame 1. A cushion 5 attached to the chair frame 1 is formed in the shape of a sealed bag, and a vibration unit 6 is fixed to the rear surface of the back of the cushion 5. It goes without saying that the vibration unit 6 may not be attached directly to the cushion 5, but may be attached via a stay or the like. In this embodiment, the vibration unit 6 is fixed at a position corresponding to the circular hole 3 formed in the canvas 2 when the cushion 5 is attached to the chair frame. A liquid 7 is sealed inside the cushion 5 as a vibration medium for the vibration unit 6. Here, the type of liquid 7 as the vibration medium is not limited to a specific type. Alternatively, gas may be enclosed. Since the present invention is constructed as described above, when the vibration unit 6 vibrates, the vibration is evenly transmitted throughout the liquid 7, which is the vibration medium, according to Pascal's principle.

As described above, the present invention is a vibration transmission mechanism for a realistic sensation reproducing device in which liquid 7 or gas is sealed as a vibration medium of a vibration unit 6 inside a sealed bag-like cushion 5.

Therefore, according to Pascal's principle, the vibration unit 6
The vibrations generated are evenly transmitted to the entire cushion 5, so the vibrations can be efficiently transmitted to the entire sitting human body. In particular, when gas is used as the vibration medium, the overall weight of the device can be reduced. Furthermore, according to the present invention, the inertial force efficiency of the vibration unit 6 does not decrease, so even if a thin mat or the like is interposed between the human body and the cushion 5, the vibrations are transmitted to the human body, and the cushion There are no variations in vibration due to variations in material, hardness, etc. Appropriate vibration can be obtained by adjusting the viscosity and loss of the liquid 7.
