In some embodiments, as shown in fig. 1, the audio device 100 may include a sealed enclosure 102, with a sound generating mechanism 104, a cavity 106, and a gas storage unit 108 disposed within the sealed enclosure 102.

In some embodiments, the sealed enclosure 102 may be fabricated from a flexible material. For example, the sealed housing 102 may be made of silicone, rubber, thermoplastic elastomer (TPE), and the like. In some embodiments, the sealed enclosure 102 may also be made of other materials. For example, other materials may include, but are not limited to, plastic, acrylic, glass, wood, bamboo, metal, and the like. In some embodiments, the sealed enclosure 102 may also be formed from a combination of two or more of the above materials. The sealed housing 102 may be an integrally formed structure; multiple parts can be connected and formed. By arranging the sealing shell 102, the internal parts can be effectively isolated from the external environment, and good waterproof and dustproof effects are achieved. The sound emitting device 104 is a means for emitting sound in the audio apparatus 100. The sound generating device 104 may include a speaker, a horn, or the like. For example, a loudspeaker may emit an acoustic signal through a diaphragm. The sound generator 104 may also include any other device capable of generating sound, and is not limited herein.

The audio device 100 may include one or more cavities 106. Each cavity 106 may correspond to a separate space. In some embodiments, the audio device 100 may contain only one cavity 106, which cavity 106 may be understood as the space within the sealed enclosure 102. In some embodiments, the audio device 100 may include two or more cavities 106, and the two or more cavities 106 may be spaced apart or independently arranged. Each cavity 106 may include a space bounded by the walls of the cavity 106. When the audio device 100 includes only one cavity 106, the walls of the cavity 106 are the sealed enclosure 102. In some embodiments, the cavity 106 walls may be made of a flexible material. For example, the material of the cavity 106 wall may include, but is not limited to, one or more of rubber, aluminum latex, plastic, oxford, polyvinyl chloride (PVC), aluminum foil, nylon (PA), Polyethylene (PE), and the like. The walls of the chamber 106 may automatically expand or contract depending on the pressure of the gas inside the chamber 106. In some embodiments, the number, shape, volume, etc. of the cavities 106 may be set according to the functional requirements of the audio device 100 itself, and are not limited herein.

One or more gas storage units 108 may be included in the audio device 100. In some embodiments, the gas storage cells 108 may include a space surrounded by cell walls. In some embodiments, the cell walls may be made of a flexible material. For example, the material of the cell wall may include, but is not limited to, one or more of rubber, aluminum latex, plastic, oxford, polyvinyl chloride (PVC), aluminum foil, nylon (PA), Polyethylene (PE), and the like. In some embodiments, one or more gas storage units 108 may be in communication with one or more chambers 106. For example, the gas storage unit 108 may be connected to the chamber 106 via a tubular passage. The materials of the walls of the cavity 106 and the cell walls may be the same or different.

In some embodiments, the audio device 100 may include a plurality of gas storage units 108, with at least two of the gas storage units 108 having different types of gas stored therein. For example, the gas storage units 108 may include four, and the four gas storage units 108 may store four different types of gases, respectively. Since different gases have different effects on the frequency, loudness, and the like of sound, the provision of a plurality of gases helps to achieve a variety of adjustments of the audio device 100. In some embodiments, the gas may include, but is not limited to, a combination of one or more of nitric oxide, nitrogen dioxide, nitrous oxide, carbon dioxide, an inert gas, and chlorine gas. In some alternative embodiments, the gas storage units 108 may be only one in number. The gas storage unit 108 may store one or more gases of a particular composition. For example, the gas storage unit 108 may store three gases of specific compositions and specific gravities.

The gas in the gas storage unit 108 can be introduced into the cavity 106 to adjust the playing effect of the audio device 100. In some embodiments, the process of passing the gas in the gas storage unit 108 into the chamber 106 and/or recycling the gas in the chamber 106 back to the gas storage unit 108 may be performed by manual adjustment. For example, a channel between the gas storage unit 108 and the chamber 106 may be provided with a pressure valve, and a user may force gas in the gas storage unit 108 into the chamber 106 by squeezing the gas storage unit 108. For another example, the user may press the chamber 106 to cause the gas in the chamber 106 to flow into the gas storage unit 108. In some embodiments, a gas control device 110 may be disposed between the chamber 106 and the gas storage unit 108, and the gas control device 110 may be used to control the gas communication between the chamber 106 and the gas storage unit 108.

In some embodiments, different types of gases stored in at least two gas storage units 108 can be passed into the same chamber 106. For example, when there is only one chamber 106, all of the gas storage units 108 may be in communication with that chamber 106. Also for example, two or more gas storage units 108 may be in communication with the same chamber 106. By communicating gas storage units 108 storing different types of gases with the same chamber 106, the different gases can be allowed to mix (e.g., in a predetermined ratio) in the chamber 106. And the mixed gas with different proportions can change different playing effects of the audio device 100. In some embodiments, the gas storage unit 108 may also recover the mixed gas within the cavity 106. For example, two or more gas storage units 108 may sequentially recover the corresponding gases in the cavity 106 according to the stratification phenomenon caused by the different densities of the gases.

In some embodiments, the audio device 100 may include a plurality of cavities 106 corresponding to the plurality of gas storage units 108, respectively, and the gas in each gas storage unit 108 may be capable of being passed into its corresponding cavity 106. By limiting the chambers 106 to communicate only with the corresponding gas storage units 108, the gas species in each chamber 106 can be better controlled. Through ventilating a plurality of cavities 106 respectively or in combination, can make these a plurality of cavities 106 produce different influences to the propagation of sound, and then realize the regulation of sound playing effect. For example, the audio device 100 may include four cavities 106, only one of the cavities 106 may be vented at a time; two, three or four of the chambers 106 may also be vented at a time. In some embodiments, the volume of gas within each cavity 106 may be the same or different for cavities 106 that have been vented.

In some embodiments, the cavity 106 may be disposed in a path of travel of sound emitted by the sound emitting device 104. Arranged in the propagation path is understood to mean arranged in the region which is covered by the outward extension of the bell mouth of the generating device. Through such an arrangement, the cavity 106 (and the gas therein) can have a sufficient effect on the emitted sound, so as to effectively adjust the playing effect of the audio device 100.

In some embodiments, the gas storage unit 108 may be disposed outside of the path of travel of the sound emitted by the sound emitting device 104. Arranged outside the propagation path is understood to mean arranged outside the range which can be covered by the outward extension of the bell mouth of the generating device. For example, the gas storage unit 108 may be disposed behind the bell mouth. By disposing the gas storage unit 108 outside the propagation path of the sound emitted by the sound emitting device 104, the disturbance of the emitted sound by the gas storage unit 108 can be reduced.

In some embodiments, a passage may be provided between the sound generating device 104 (e.g., the bell mouth) and the cavity 106, and the diameter of the passage increases from the bell mouth to the cavity 106, so that the sound emitted from the bell mouth can better propagate outwards through the cavity 106.

In some embodiments, a gas control device 110 is disposed between the chamber 106 and the gas storage unit 108, and the gas control device 110 can be used to control the gas communication between the chamber 106 and the gas storage unit 108. For example, the gas control device 110 may be disposed in a channel between the gas storage unit 108 and the chamber 106. The mutual communication between the cavities 106 and the gas storage units 108 may include the gas in the gas storage units 108 being introduced into the corresponding cavities 106, or the gas being recovered from the cavities 106 into the corresponding gas storage units 108. In some embodiments, the gas control device 110 may include a bi-directional inflator or two uni-directional inflators. In some embodiments, gas control device 110 may also include other devices that enable bi-directional gas flow regulation.

In some embodiments, the audio device 100 may include a controller 112 and a pressure sensor 114. A gas pressure sensor 114 can be used to detect the gas pressure within the chamber 106, and a controller 112 is used to control the gas control device 110 according to the signal from the gas pressure sensor 114. For example, when the controller 112 determines that the gas pressure inside the chamber 106 is greater than a certain threshold value according to the signal of the gas pressure sensor 114, the controller 112 may generate and send a command to the gas control device 110. The gas control device 110 receives the instruction and performs an operation of reducing the gas pressure inside the corresponding chamber 106. The operation may include causing the corresponding gas storage unit 108 to recover a portion of the gas from the high pressure chamber to reduce the intra-chamber gas pressure of the high pressure chamber to within a reasonable threshold range. For another example, when the controller 112 determines that the gas pressure inside the cavity is less than a certain threshold according to the signal of the gas pressure sensor 114, the controller 112 may generate and send a command to the gas control device 110. The gas control device 110 receives the instruction and performs an operation of increasing the gas pressure inside the corresponding chamber. The operation may include causing the corresponding gas storage unit 108 to release a portion of the gas to the low pressure cavity to raise the intra-cavity gas pressure of the low pressure cavity to within a reasonable threshold range. By detecting and adjusting the air pressure of the cavity 106, the pressure inside the cavity 106 can be effectively adjusted to be within a reasonable threshold range, so that the wall of the cavity 106 can be prevented from being broken due to overlarge air pressure inside the cavity 106; meanwhile, the air pressure (or volume) of the cavity 106 can be controlled within a reasonable range, so as to adjust the playing effect of the audio device 100.

In some embodiments, the controller 112 may be used to control the flow rate of gas through the gas control device 110. By adjusting the gas flow rate, the controller 112 can control the changing speed of the volume of the cavity 106 (or the air pressure in the cavity 106), thereby better adjusting the playing effect of the audio device 100.

In some embodiments, the controller 112 and the volume sensor 116 may be included in the audio device 100. The volume sensor 116 is used for detecting the volume of the chamber 106, and the controller 112 is used for controlling the gas control device 110 according to the signal of the volume sensor 116. In some embodiments, the volume sensor 116 may detect the volume of the cavity 106 based on ultrasound, laser, imaging, and the like techniques. The volume sensor 116 may be disposed within the cavity 106 or outside the cavity 106. The controller 112 controls the gas control device 110 according to the signal detected by the volume sensor 116, and may include controlling the gas control unit to perform an operation of allowing the gas to be released to the chamber 106 or recovered to the gas storage unit 108. For example, when volume sensor 116 senses that the volume of chamber 106 is less than or greater than a certain threshold range, controller 112 may increase or decrease the volume of chamber 106 by controlling gas control device 110. In some embodiments, when the volume of the cavity 106 is increased by the gas control device 110, the bass effect may be enhanced, otherwise, the treble effect is enhanced, thereby achieving effective control of the sound playing effect.

In some embodiments, the audio device 100 may include a controller 112 and a microphone 122. The microphone 122 is used for collecting the sound emitted by the sound generating device 104, and the controller 112 is used for controlling the gas control device 110 according to the sound signal collected by the microphone 122. In some embodiments, the controller 112 may identify the type of sound from the sound signal collected by the microphone 122; and controls the gas control device 110 according to the sound type. In some embodiments, the sound types may be distinguished by a combination of one or more of audio, pitch, timbre and loudness. The controller 112 controls the gas control device 110 according to the sound signal, and may include controlling the gas control unit to perform an operation of allowing the gas to be released into the chamber 106 or recovered into the gas storage unit 108. For example, if the controller 112 determines that the type of the generated sound is mainly high-frequency output according to the sound signal, the controller 112 may generate an instruction to control the gas control device 110 to adjust parameters related to the specific gravity, the gas pressure, and the volume of the gas inside the one or more cavities 106, so that the high-frequency output of the sound is guaranteed. For another example, if the controller 112 determines that the type of the generated sound is bass music according to the sound signal, the controller 112 may generate an instruction to control the gas control device 110 to adjust parameters related to the specific gravity, the gas pressure, and the volume of the gas inside the one or more chambers 106 (e.g., increase the volume of the chamber 106 to a preset threshold value) so as to enhance the bass effect of the music. In some embodiments, the controller 112 may determine the adjustment instruction according to the type of sound based on a preset rule. In the embodiment of the present application, the microphone 122 detects the sound signal in real time, so that the gas control device 110 can efficiently adjust the sound playing effect in real time, which is helpful for improving the accuracy and the effectiveness of the audio device 100 in adjusting the sound.

In some embodiments, the audio device 100 may include a controller 112, a temperature sensor 120, and a temperature regulator 118.

The controller 112 may be used to control the temperature regulator 118 to regulate the temperature within the sealed enclosure 102 based on the signal from the temperature sensor 120. In some embodiments, the temperature of the gas within the sealed enclosure 102 (e.g., within the cavity 106) may have an effect on the playing effect of the sound (e.g., affect the loudness of the sound). By providing the controller 112, the temperature sensor 120 and the temperature regulator 118, the temperature inside the sealed housing 102 can be effectively regulated, thereby regulating the playing effect of the audio device 100.

In some embodiments, the audio device 100 may include a controller 112, a humidity sensor 126, and a humidity regulator 124. In some embodiments, the humidity sensor 126 and the humidity regulator 124 are disposed within the sealed enclosure 102.

In some embodiments, the humidity of the gas within the sealed enclosure 102 (e.g., within the cavity 106) may have an effect on the sound playing effect (e.g., affect the loudness of the sound). By arranging the controller 112, the humidity sensor 126 and the humidity regulator 124, the humidity inside the sealed enclosure 102 can be effectively regulated, and thus the playing effect of the audio device 100 can be regulated.

In some embodiments, the audio device 100 may include one or more of an air pressure sensor 114, a volume sensor 116, a temperature sensor 120, a temperature regulator 118, a humidity sensor 126, a humidity regulator 124, a microphone 122, and a controller 112.
