Description

Technical Field

[0001] The present invention relates to the technical field of audio equipment, and more particularly to a tactile sensor and a system thereof, and an audio system of a cinema. Background Art

[0002] In bars, performances, cinemas, and KTV rooms, in order to increase the sense of shock when listening to music, watching programs, and watching movies, large-size, high-power bass speakers are usually used to emit bass frequencies with large sound pressure. The low frequency is transmitted through the air, human clothes, seats, etc. to feel a certain large dynamic shock effect. In this process, there are the following disadvantages:

[0003] 1. The speaker relies on the paper cone to drive the air vibration to produce sound. The paper cone can be easily damaged if used for a long time.

[0004] 2. High-power bass speakers can only produce a shocking effect when the sound pressure is turned up to a very high level. However, the body functions of the elderly and children in the audience may not be able to withstand the sound stimulation of such high sound pressure, and they may experience physical discomfort.

[0005] 3. If you want to get a sufficiently shocking feeling at home, when the volume of the home theater sound system is turned up to a relatively loud level, the sound will quickly disturb the neighbors next door, which may easily cause nuisance problems.

[0006] 4. Large dynamic shock effects require the use of high-power, large-size speakers. When the venue area does not allow the placement of large-size speakers, the size of the speakers must be reduced to reduce the speaker power, which will affect the shock effects of music, movie plots, etc. and will be greatly reduced.

[0007] 5. Using multiple high-power speakers also requires high-power amplifier drivers in terms of amplifier matching, which results in high energy consumption and is not environmentally friendly.

[0008] 6. There are also special groups, such as the deaf and mute people, who cannot hear sounds and cannot perceive and express sounds well, which affects their work and study.

[0009] When multiple speakers sound at the same time, some frequencies may be canceled out, resulting in problems such as comb filtering and phase cancellation. Summary of the invention

[0037] Figures 1 to 6 are drawings of the present invention.

[0038] This embodiment provides a tactile sensor Q, see Figures 1 to 4 , including a fixed plate 10, a guide rod 11 arranged on one side of the fixed plate 10, and a movable block 12 movably connected along the guide rod 11. The fixed plate 10 is provided with a coil 13, and the coil 13 is located on the outside of the guide rod 11. The movable block 12 is provided with a magnet 14 near the coil 13. The coil 13 is connected to the audio signal so that the coil 13 and the magnet 14 interact with each other, and the movable block 12 moves along the guide rod 11.

[0039] Preferably, the magnet 14 is a rare earth neodymium iron boron permanent magnet.

[0040] The coil 13 is connected to the audio signal. Since the audio signal is the current after the power amplifier, the current will increase, and the current of the coil 13 changes with the change of the audio signal, so that the coil 13 with the changed current cuts the magnetic induction line in the magnetic field formed by the magnet 14, so that a force is generated between the magnet 14 and the coil 13. Because the coil 13 is fixed on the fixed plate 10, and the magnet 14 is fixed on the movable block 12, the force between the coil 13 and the magnet 14 makes the movable block 12 move with the audio signal. The change of the current in the coil 13 makes the movable block 12 reciprocate along the guide rod 11. The movable block 12 hits the carrier (such as furniture, base plate, wall, etc.) on which it is installed to obtain a strong vibration feeling.

[0041] The audio signal is an ultra-low frequency electric power signal below 100 Hz, which is amplified by a power amplifier and then electrically connected to the tactile sensor, so that the ultra-low frequency electric power signal is expressed in the form of vibration through the tactile sensor.

[0042] See also Figure 3, a mounting portion 121 is radially extended at one end of the movable block 12. The magnet 14 is fixed to the mounting portion 121. The movable block 12 includes, in addition to the mounting portion 121, a sleeve portion 122 that slides with the guide rod 11. The mounting portion 121 is circumferentially arranged at one end of the sleeve portion 122, and the magnet 14 is also circumferentially arranged on the mounting portion 121. Preferably, the magnet 14, the mounting portion 121 and the sleeve portion 122 are concentrically designed to maintain the smooth movement of the movable block 12. Preferably, the mounting portion 121 and the sleeve portion 122 are integrally formed to form the movable block 12.

[0043] The magnet 14 is an annular structure and is located outside the coil 13, so that the coil 13 can cut the magnetic induction lines of the magnetic field of the magnet 14 with the largest area, and the movable block 12 is forced to reciprocate along the guide rod 11. In the magnetic field of the magnet 14, the change in direction and magnitude of the current in the coil 13 can cut the magnetic induction lines, so that a force is generated between the coil 13 and the magnet 14.

[0044] Preferably, the coil 13 is fixed to the fixed plate 10 through a provided frame 15. The coil 13 extends between the inner side of the magnet 14 and the guide rod 11. The frame 15 is fixed to a side of the fixed plate 10 where the guide rod 11 is provided, and extends between the inner side of the magnet 14 and the guide rod 11, so that the coil 13 is fixed to the frame 15.

[0045] Preferably, a first buffer pad 16 is provided at one moving end of the movable block 12. The first buffer pad 16 prevents the movable block 12 from being rigidly impacted by an impact object.

[0046] A baffle 17 is provided on one side of the magnet 14 near the fixed plate 10. The baffle 17 is connected to the movable block 12 through a sealing plate 18. The baffle 17 is arranged outside the coil 13, and the outermost end is fixedly connected to the movable block 12 through the sealing plate 18. The sealing plate 18 can be used as a sealing plate to prevent dust and other debris from entering the magnet 14.

[0047] One end face of the baffle 17 is fixed to the magnet 14, and a second buffer pad 19 and / or a breathable ring 21 are provided between the other end face and the fixed plate 10. The second buffer pad 19 can be used as a buffer between the movable blocks 12, and the breathable ring 21 can be used to block dust.

[0048] Preferably, the baffle 17 and the movable block 12 are both made of magnetic conductive materials.

[0049] Furthermore, a plurality of sealing rings 22 are provided between the guide rod 11 and the movable block 12 to prevent dust, water and other debris from entering the coil 13 .

[0050] The coil 13 is connected to the audio signal via a connecting wire 23 , wherein a connector 24 is provided at one end of the connecting wire 23 .

[0051] Preferably, the fixing plate 10 and the guide rod are provided with fixing holes 25 for fixing the fixing plate 10 on the load. During installation, the fixing plate 10 can be fixed on the load by passing bolts through the fixing holes 25, and one end of the movable block 12 faces the load. During operation, the movable block 12 reciprocates along the guide rod 11 and collides with the load to cause the load to vibrate.

[0052] The tactile sensor Q uses the audio signal to convert into the kinetic energy of vibration, and can be applied in many fields, such as special education, cinemas, families, entertainment venues, etc. Special education, for special children in special education schools, such as students with congenital deafness, normal education and teaching cannot perceive sound, but the human tactile sensor of the present invention enables deaf-mute students to gain sound perception. It can be installed on the bottom of floor tiles, walls, seats, etc., and by combining the rhythm of music, the floor, walls, seats, etc. will emit regular and rhythmic vibrations, so that the changes in sound can be perceived through the touch of the human body.

[0053] In the cinema, this tactile sensor Q is installed at the bottom of the sofa or the floor. Through the playback of the film, the low-frequency sound signal is converted into kinetic energy synchronously, thereby driving the sofa or floor to vibrate and sense the human body. Combining the plot and the sound of the film, it can bring an auditory experience. At the same time, it can also bring a tactile experience to the body, so that the shocking effect of the big scenes in the film can be felt, without the need to turn up the sound of the speakers to a very high level to produce an auditory and tactile shock.

[0054] In a bar, many speakers are usually turned up to a deafening sound to achieve the effect of perceiving the shock of music. The tactile sensor Q is installed on the sofa, floor, etc. The connected audio signal is the music signal, which will reduce the investment in expensive audio equipment in the bar, thereby improving the tactile effect.

[0055] A tactile system with a tactile sensor 30, see Figure 5, including the above-mentioned tactile sensor Q, power amplifier 31, audio processor 32 and decoding processor 33. The coil 13 is connected to the power amplifier 31. The power amplifier 31 is connected to the decoding processor 32 through the audio processor 33. The decoding processor 32 is connected to the audio source 34. The audio processor 32 is used for frequency division processing, mainly used to separate ultra-low frequency electric power signals below 100 Hz, but not limited to ultra-low frequency electric power signals below 100 Hz. After separating the ultra-low frequency electric power signals below 100 Hz, the power amplifier 31 performs power amplification processing so that the current meets the use of the tactile sensor Q. After the power amplifier 31 processes the current, it is connected to the coil 13. The current in the coil 13 changes with the change of the ultra-low frequency electric power signal, so that the current in the coil 13 changes, and then the magnetic field between the coil 13 and the magnet 14 generates a mutual force. Since the coil 13 is fixed, the movable block 12 of the fixed magnet 14 will move along the guide rod 11.

[0056] In this embodiment, the power amplifier 31 is mainly a two-channel power amplifier. Each two-channel power amplifier is connected to two tactile sensors Q. They can be used as a group of tactile sensors Q and are all installed on the same or adjacent carriers.

[0057] The audio source 34 may be a video player, a music player, etc.

[0058] A cinema audio system, see Figure 6 , including the above-mentioned tactile system 30 with tactile sensors, and also including a rear surround power amplifier 41, a subwoofer power amplifier 42, a center power amplifier 43, a surround power amplifier 44 and a main speaker power amplifier 45. Among them, the rear surround power amplifier 41, the subwoofer power amplifier 42, the center power amplifier 43, the surround power amplifier 44 and the main speaker power amplifier 45 are all electrically connected to the decoding processor 33. The rear surround power amplifier 41 is electrically connected to the provided cinema rear speaker 46. The subwoofer power amplifier 42 is electrically connected to the provided cinema subwoofer 47. The center power amplifier 43 is electrically connected to the provided cinema center speaker 53. The surround power amplifier 44 is electrically connected to the provided cinema left and right surround speakers 48. The main speaker power amplifier 45 is electrically connected to the provided cinema main speaker 49. Among them, the tactile sensor Q is set at the seats, floors, walls and other locations of the cinema, which can enhance the sound effects of the cinema. As the audio signal changes, the tactile sensor Q converts the electrical energy signal of the audio signal into kinetic energy that changes with the audio signal, thereby enhancing the sound characteristics of the theater.

[0059] The system also includes a projector 51 and a screen 52 electrically connected to the decoding processor 33 .

[0060] Compared with the prior art, this embodiment has the characteristics of small size, easy installation, good vibration tactile effect and low cost. The tactile sensor can vibrate with the change of audio signal to obtain shocking effect, avoid using high-power speakers to obtain sensory stimulation with loud sound, reduce sound pollution, reduce power consumption, and avoid the problems of sound comb filtering and phase cancellation.

[0061] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this.
