Unless specifically defined otherwise, these terms are not to be interpreted in an idealized or overly formal sense.
Referring to fig. 1, an application diagram of a sound absorbing device 100 according to an embodiment of the invention is shown. As shown in fig. 1, a sound absorbing device 100 is adapted to be worn on the face of a user to cover the mouth 200 of the user.
Please refer to fig. 2 to 3. Fig. 2 is a schematic cross-sectional view of the sound absorbing device 100 of fig. 1. Fig. 3 is a perspective cross-sectional view of the sound-absorbing device 100 of fig. 1. As shown in fig. 2 to 3, the sound absorbing device 100 includes a cover 110, a ventilation structure 120, and a sound absorbing unit 130. The cover 110 has a first chamber 111 and a first opening 112 and a second opening 113 opposite to the first opening 112, the first chamber 111 communicates with the first opening 112 and the second opening 113, and the first opening 112 is disposed corresponding to the mouth 200 (see fig. 1). The ventilation structure 120 is disposed at the second opening 113 of the cover 110, the ventilation structure 120 has a second chamber 121 and opposite third and fourth openings 122 and 123, the second chamber 121 communicates the third and fourth openings 122 and 123, the third opening 122 is at least partially located in the first chamber 111 of the cover 110, and the fourth opening 123 is far away from the first opening 112 of the cover 110. In addition, the ventilation structure 120 includes at least one plate 124, the plate 124 is disposed in the second chamber 121, the plate 124 has an active surface 125, the active surface 125 faces the third opening 122, a gap G is formed between an edge 126 of the plate 124 and an inner wall 120a of the ventilation structure 120, and the inner wall 120a of the ventilation structure 120 surrounds the second chamber 121. The sound absorption portion 130 is disposed between the ventilation structure 120 and the first opening 112.
Specifically, when the acoustic absorption device 100 is worn by the tourette patient, the first opening 112 of the cover 110 corresponds to the mouth 200 thereof, and the cover 110 covers the mouth 200, so that the mouth 200 is shielded by the acoustic absorption device 100. When the mouth 200 of a tourette's patient makes an involuntary and involuntary sound due to vocal cramps (vocal tics), the emitted sound is trapped within the first chamber 111 of the mask body 110. Furthermore, the cover 110 is made of a soft material, which has a sound insulation effect, so that the sound emitted from the mouth 200 of the patient suffering from tourette syndrome is not easily transmitted from the inside of the first chamber 111 of the cover 110 to the outside of the cover 110. Therefore, by wearing the sound absorbing device 100, the influence of the sound emitted from the mouth 200 of the patient with tourette syndrome on other people can be effectively reduced.
In practical applications, the contour of the first opening 112 of the cover 110 can be designed according to the surface shape of the patient with tourette syndrome, so that the cover 110 covers the mouth 200 of the patient with tourette syndrome more tightly, thereby improving the sound-sealing effect of the cover 110.
On the other hand, the sound absorbing device 100 includes the sound absorbing part 130, and the sound absorbing part 130 is located in the first cavity 111 of the cover 110, and more specifically, the sound absorbing part 130 is disposed between the ventilation structure 120 and the first opening 112 of the cover 110. In the present embodiment, the sound absorbing part 130 includes a sound absorbing material, so that the sound emitted from the mouth 200 of the tourette syndrome patient is absorbed by the sound absorbing part 130 in the first cavity 111 of the cover 110, and thus, the volume of the sound in the first cavity 111 is effectively reduced. Therefore, by wearing the sound absorbing device 100, the influence of the sound emitted from the mouth 200 of the patient with tourette syndrome on other people can be further effectively reduced.
In addition, the sound absorbing part 130 includes a first sub sound absorbing part 131 and a second sub sound absorbing part 133. The first sub sound-absorbing part 131 has a sound-absorbing surface 132, and the sound-absorbing surface 132 faces the first opening 112. The second sub sound-absorbing part 133 is located between the ventilation structure 120 and the first sub sound-absorbing part 131. The first sub sound absorbing part 131 and the second sub sound absorbing part 133 include sound absorbing materials, respectively. In this way, the sound absorbing surface 132 of the first sub sound absorbing part 131 facing the first opening 112 can effectively absorb the sound emitted from the mouth 200 of the patient with tourette syndrome, and the sound volume can be effectively reduced. In addition, the first sub sound absorption part 131 is exposed to other surfaces in the first chamber 111, and the second sub sound absorption part 133 is exposed to surfaces in the first chamber 111, which can help to absorb sound emitted from the mouth 200 of the patient suffering from tourette syndrome, so that the volume of the sound can be effectively reduced.
It is noted that the projection area of the first sub sound absorbing part 131 towards the ventilation structure 120 is larger than the third opening 122 of the ventilation structure 120. In other words, the sound emitted from the mouth 200 of the tourette syndrome patient is blocked by at least the first sub sound-absorbing part 131 and is not directly transmitted to the third opening 122 of the ventilation structure 120. In this way, the sound emitted from the mouth 200 of the tourette syndrome patient passes through the first sub sound absorbing part 131 of the sound absorbing part 130 before reaching the ventilation structure 120. That is, the sound reaching the ventilation structure 120 has its volume reduced at least by being absorbed by the first sub sound-absorbing part 131 of the sound-absorbing part 130.
As shown in fig. 2-3, the ventilation structure 120 further comprises a duct 127. One end of the duct 127 communicates with the fourth opening 123 of the ventilation structure 120, and the other end faces the third opening 122 of the ventilation structure 120. By connecting the fourth opening 123 with the third opening 122 through the conduit 127, air can enter the second chamber 121 of the ventilation structure 120 from the outside and then enter the first chamber 111 of the enclosure 110, whereas air can enter the second chamber 121 of the ventilation structure 120 from the first chamber 111 of the enclosure 110 and then exit the sound-absorbing device 100 through the conduit 127. In this way, the patient with tourette syndrome can breathe normally after wearing the sound absorbing device 100.
As mentioned above, the plate 124 is disposed in the second chamber 121 of the ventilation structure 120, the acting surface 125 of the plate 124 faces the third opening 122, and a gap G is formed between the edge 126 of the plate 124 and the inner wall 120a of the ventilation structure 120. As such, when the sound emitted from the mouth 200 of the tourette syndrome patient reaches the ventilation structure 120, the sound enters the second chamber 121 through the third opening 122 of the ventilation structure 120 and then reaches the action surface 125 of the plate 124. Since the edge 126 of the plate 124 near the gap G is a free end, the sound reaching the action surface 125 of the plate 124 causes the plate 124 to vibrate with the end far from the gap G as a base point. In other words, at least a portion of the energy of the sound is converted into energy for vibrating the plate 124. In this way, the sound entering the second chamber 121 through the third opening 122 of the ventilation structure 120 consumes energy of the vibration of the plate 124, and thus, the sound emitted from the mouth 200 of the tourette patient can be further attenuated.
In summary, by wearing the sound-absorbing device 100, the sound emitted from the mouth 200 of the patient with tourette syndrome is limited by the following three ways to effectively reduce the influence on other people, including: blocking sound emitted from the mouth 200 of a patient with tourette's syndrome with a mask body 110 having a sound-insulating effect; secondly, the sound absorption part 130 absorbs the sound in the first chamber 111 to reduce the volume of the sound; and (iii) dissipating the energy of the sound entering the second chamber 121 with the vibration of the plate body 124.
In order to make the plate 124 resonate with sound (resonance) to achieve better sound attenuation effect, the thickness of the plate 124 can be adjusted according to actual conditions. For example, the thickness of the plate 124 may be about 0.5mm to 1.0mm, i.e., 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1.0mm, etc. However, it should be understood that the thickness of the plate 124 is only exemplary and not intended to limit the present invention, and those skilled in the art should appropriately select the thickness of the plate 124 according to the actual requirement.
On the other hand, the sound-absorbing device 100 may further include a cloth 140, and in practical applications, the cloth 140 at least partially covers the plate body 124 to generate an additional sound-absorbing effect. In the present embodiment, the cloth 140 may be made of a non-woven fabric, but the invention is not limited thereto.
Furthermore, the sound absorbing device 100 may further include a metal foil 150, and in practical applications, the metal foil 150 at least partially covers the plate body 124 to adjust the overall resonance frequency of the plate body 124 and the metal foil 150, thereby enhancing the effect of dissipating the sound energy by vibration. In the present embodiment, the metal foil 150 may be a copper foil, but the present invention is not limited thereto.
In practical applications, according to practical situations, a user may cover the plate body 124 with the metal foil 150 and then cover the metal foil 150 with the cloth 140 as shown in fig. 2 to 3. Alternatively, in other embodiments, the user may cover the plate 124 with the cloth 140 and then cover the cloth 140 with the metal foil 150.
In the present embodiment, the number of the plate bodies 124 is plural, and the plate bodies 124 are arranged along between the third opening 122 and the fourth opening 123, thereby enhancing an effect of consuming energy of sound by vibration. For example, as shown in fig. 2 to 3, the number of the plate bodies 124 is 3.
More specifically, the plate body 124 has a through hole 124a, and the duct 127 of the ventilation structure 120 passes through the through hole 124a of the plate body 124 and is connected to the plate body 124. As shown in fig. 2-3, the inner wall 124b surrounding the perforation 124a is connected to the conduit 127 of the venting structure 120. That is, the plate body 124 vibrates with the inner wall 124b of the connecting duct 127 as a base point.
Further, in the present embodiment, the sound absorbing device 100 further includes a metal sheet 160. The metal sheet 160 is located between the second opening 113 of the cover 110 and the sound absorption portion 130, the metal sheet 160 has a through hole 160a, and the ventilation structure 120 at least partially passes through the through hole 160a of the metal sheet 160 and is connected to the metal sheet 160. As shown in fig. 2 to 3, an inner wall 160b surrounding the perforation 160a is connected to the ventilation structure 120. Similarly, the metal sheet 160 generates vibration based on the inner wall 160b of the connecting ventilation structure 120 to dissipate the energy of the sound in the first chamber 111.
In conclusion, compared with the prior art, the technical scheme of the invention has obvious advantages and beneficial effects. Through the technical scheme, considerable technical progress can be achieved, the industrial wide utilization value is achieved, and the method at least has the following advantages:
(1) by wearing the sound absorbing device, the sound emitted from the mouth of the patients with Tourette's syndrome can be limited by the following three ways to effectively reduce the influence on other people, including: the method comprises the following steps of (I) blocking sound emitted from the mouth of a patient suffering from Torreya disease by using a cover body with a sound insulation effect; absorbing the sound in the first cavity by the sound absorption part to reduce the volume of the sound; and (iii) dissipating the energy of the sound entering the second chamber with the vibration of the plate.
(2) Through the fourth opening of pipe intercommunication ventilation structure with towards the third opening, the air can get into the second cavity of ventilation structure from the external world, then gets into the first cavity of the cover body, otherwise, the air can get into the second cavity of ventilation structure from the first cavity of the cover body, then leaves sound absorbing device through the pipe. Thus, the patients with Tourette's disease can breathe normally after wearing the sound-absorbing device.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
