DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0037] The detailed description and technical contents of the invention are described with reference to the drawings as follows.

[0038] With reference to FIG. 1 to FIG. 9, the invention provides a chair 100 capable of providing somatosensory vibration based on an external signal. The invention comprises a body 10, a plurality of vibrators 20, and a vibration controller 40. The body 10 for sitting comprises a framework 11 and a plurality of mesh fabrics 12 disposed on the framework 11. The vibrators 20 are hung on the framework 11 through at least two connectors 21 and are arranged corresponding to one of the mesh fabrics 12. In detail, a bearing surface 121 on the framework 11 for bearing is formed by the mesh fabrics 12. The mesh fabrics 12 include a plurality of meshes on the side which is facing the sitter (such as the bearing surface 121). The diameter of the meshes is larger than the knitting of the mesh fabrics 12. In one embodiment, the mesh fabrics 12 are one-piece knitted by a knitting technique. The mesh fabrics 12 are able to be implemented in a single, double, or multi-layer construction. In a multi-layer construction, the mesh fabrics 12 are able to be implemented in a spacer fabric form commonly known as a sandwich mesh. The mesh on a surface where the spacer fabric is located is also formed by knitting techniques. In addition, as the mesh fabrics 12 are implemented in a double-layer or multi-layer construction, the mesh fabrics 12 are able to be one of the following states when viewed from one side: full penetration, half penetration, no penetration. The vibrators 20 are provided at the lower side of bearing surface 121 without affecting the seating function of the body 10. The vibrators 20 are provided with a vibration surface 22, and the vibration surface 22 is directly contacted with one of the mesh fabrics 12. As each of the vibrators 20 operates based on at least one vibration starting signal 41, the vibration surface 22 directly vibrates the corresponding mesh fabrics 12. The vibration controller 40 is disposed on the body 10 and is data connected with the vibrators 20. The vibration controller 40 receives an external signal 601, which is from an external control source 600 in data connection with the vibration controller 40. The vibration controller 40 generates the at least one vibration starting signal 41 based on the external signal 601 and transmits the at least one vibration starting signal 41 to the vibrators 20. The vibration controller 40 transmits the at least one vibration starting signal 41 to the vibrators 20 via wireless transmission, such as Bluetooth, or via a plurality of transmission lines (not shown) connecting the vibration controller 40 and the vibrators 20 in a wired manner. The transmission lines could be accommodated in the mesh fabrics 12 during implementation so as to prevent the transmission lines from scattering outside the body 10.

[0039] Next, the implementation of the chair 100 of the invention is described. Assume initially that the vibration controller 40 does not receive the external signal 601 and is not driven. Once the vibration controller 40 receives the external signal 601 from the external control source 60, as the external signal 601 is an audio signal, the vibration controller 40 filters the external signal 601 and then generates the at least one vibration starting signal 41 based on the filtered external signal 601. Once the external signal 601 is a digital signal, the vibration controller 40 first decodes the external signal 601 and then generates the at least one vibration starting signal 41 based on the decoded external signal 601. Further, as the vibrators 20 respectively receive the at least one vibration starting signal 41, the vibrators 20 respectively operate at different amplitude levels, vibration frequencies, or vibration durations based on the received at least one vibration starting signal 41.

[0040] Accordingly, the invention receives the external signal 601 from the vibration controller 40 and the vibration controller 40 provides the start signal 41 to the vibrators 20 based on the external signal 601, so that the vibrators 20 vibrate based on the vibration starting signal 41. On the other hand, the invention provides the vibrators 20 closer to a user to improve the conventional embedding manner thereof the vibrators barely transmit a good vibration effect due to the isolation of the cushion body. Meanwhile, since the vibrators 20 of the invention are not embedded in the cushion body, the vibrators 20 vibrate with lower vibration amplitude than the conventional ones, and the influence caused when the conventional chair shakes along with the vibrators is improved. In addition, as the vibrators 20 are not locked on the chair 100, the vibrators 20 reduce collision with the chair 100 and abnormal sounds generated during collision while vibrating.

[0041] In one embodiment, a plurality of fixing hooks 111 is formed on the framework 11. The fixing hooks 111 are respectively provided for one of the connectors 21, so that the vibrators 20 are suspended on the framework 11. The vibration surface 22 of each of the vibrators 20 is not in contact with the framework 11, thereby reducing the transmission of vibration energy to the framework 11 when the vibrators 20 vibrate. In addition, the connectors 21 of the invention could respectively be an elastic band which includes the function of absorbing energy to reduce vibration of the framework 11 when the vibrators 20 vibrate.

[0042] Furthermore, the vibrators 20 are respectively provided with a damping body 23 and at least one vibration member 24 disposed on the damping body 23, wherein the damping body 23 is made of a soft material such as rubber or silica gel and is disposed on the mesh fabric 12 through hot melting and the like. The damping body 23 deforms when a user sits on the body 10, so that the discomfort caused by the user pushing against the vibration member 24 is reduced. In one embodiment, the damping body 23 includes a first surface 231 facing one of the mesh fabrics 12, a second surface 232 opposite the first surface 231, and at least one receiving groove 233 formed in the second surface 232. The damping body 23 uses the first surface 231 as the vibration surface 22, and the receiving groove 233 is used for installing the vibration member 24. The vibration member 24 is brought close to the vibration surface 22 after assembly, which means that the vibration energy is surely transmitted to the mesh fabric 12 during vibration.

[0043] In addition, in one embodiment, one of the vibrators 20 includes an auxiliary plate 25 provided at the second surface 232 and a positioning hole 26 provided at the auxiliary plate 25. The framework 11 includes an opening 112 facing the positioning hole 26 and a positioning member 113 provided at the opening 112, and the positioning member 113 is assembled in the positioning hole 26 through the opening 112 to fix the vibrator 20. Further, in order to prevent the vibrator 20 from driving the framework 11 when the vibrator 20 vibrates, the auxiliary plate 25 is provided with a buffer column 251. The buffer column 251 is provided with the positioning hole 26, thereby allowing the auxiliary plate 25 and the buffer column 251 to absorb energy when the vibrator 20 vibrates as the vibrator 20 is fixed.

[0044] Furthermore, in one embodiment, the body 10 is divided into a backrest portion 13 and a seat portion 14. At least one of the vibrators 20 is disposed on the backrest portion 13 and one of the vibrators 20 is disposed on the seat portion 14. The at least one, disposed on the backrest portion 13, of the vibrators 20 is provided with the auxiliary plate 25 and the buffer column 251. Each of the at least one, disposed on the backrest portion 13, of the vibrators 20 is provided with a plurality of vibration members 24 which are arranged at intervals and could be respectively driven to provide different vibration directivity feelings when a user sits on the chair 100. In addition, the one of the vibrators 20 disposed on the seat portion 14 is provided at one end of the seat portion 14 opposite to the backrest portion.

[0045] In another embodiment, the mesh fabrics 12 are formed with two mesh covers 122. Each of two mesh covers 122 includes an opening 123. The opening is for one of the two mesh covers 122 to sleeve on and be selectively removable from the backrest portion 13 or the seat portion 14. The two mesh covers 122 are provided with a through hole 124 at a position corresponding to each of the fixing hooks 111. The through hole 124 is used for one of the fixing hooks 111 to pass through so that the vibrators 20 could be assembled with the fixing hooks 111.

[0046] In another aspect of the invention, the control source 600 could be a multimedia device, such as a computer, a television game, a palm game, a cell phone, etc. The vibration controller 40 could receive the external signal 601 transmitted by the multimedia device via Bluetooth, WIFI, or etc. in a wireless manner, or via a signal wire (not shown). In operation, the vibration controller 40 receives the audio signal, regarded as the external signal 601, from the multimedia device. Further, since the vibrators 20 of the invention are liable to generate abnormal sounds at a vibration frequency of an excessively high frequency, the vibration controller 40 filters the audio signal after receiving the audio signal. The vibration controller 40 captures a low frequency part of the audio signal. For example, a part of the audio signal frequency is lower than 250 Hz on which is based by the vibration controller 40 to generate the vibration starting signals 41. In addition, the multimedia device could also send the digital signal to the vibration controller 40. The digital signal is regarded as the external signal 601 by the vibration controller 40, and then the vibration controller 40 decodes the digital signal to generate an audio signal. After the vibration controller 40 filtered the audio signal, a low-frequency part of the audio signal is taken to generate the vibration starting signals 41.

[0047] In addition to the foregoing, the chair 100 of the invention includes an auxiliary vibrator 50 which is disposed on the bearing surface 121 and is in data connection with the vibration controller 40. The auxiliary vibrator 50 could be controlled in the same manner as the vibrators 20, which will not be described in detail herein. Further, the auxiliary vibrator 50 of the invention could be provided to the backrest portion 13 of the body 10 in a hanging manner so that the auxiliary vibrator 50 would correspond to a user's waist.
