Description

Technical Field

[0001] This application relates to the field of sound wave generation technology, and more specifically, to a sound generation system. Background Technology

[0002] Sound wave generation systems are based on the principle of sound wave generation, which states that when an object vibrates, it propagates and vibrates in the surrounding medium (such as air or water), forming sound waves. Sound wave generation systems typically use various sound sources to generate sound waves, such as loudspeakers and ultrasonic transducers.

[0003] The sound waves generated by the aforementioned sound wave generation system are relatively simple and cannot meet the needs of various sound wave environments, resulting in low applicability of the emitted sound waves.

[0004] In conclusion, how to improve the applicability of emitted sound waves to meet the needs of various sound wave environments is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a sound generation system that improves the applicability of the emitted sound waves to meet the needs of various sound wave environments.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A sound generation system includes: a support, a synthesis cavity, a sound generation unit, and a control system; wherein the synthesis cavity is disposed inside the support, the reflective surface of the synthesis cavity faces the top of the support, and both the synthesis cavity and the support have a top-open structure; the sound generation unit includes at least two sound generator groups, each sound generator group including a fixing component and at least two sound generators, the sound generator groups are adjustablely connected to the top of the support through the fixing component, and the sound-emitting ends of all the sound generators face the reflective surface of the synthesis cavity; the control system is electrically connected to at least two of the sound generator groups.

[0008] In some embodiments, in a group of the sound generators, the fixing component is in the form of a strip structure, at least two of the sound generators are linearly distributed along the strip structure; at least two groups of sound generators are sequentially distributed radially along the support, and there is a gap between adjacent groups of sound generators.

[0009] In some embodiments, the fixing component is slidably connected to the bracket, and one of the fixing component and the bracket is provided with a damper to adjust the gap between adjacent sound generator groups.

[0010] In some embodiments, in a group of the sound generators, all the sound generators are equidistant from the reflective surface of the synthesis cavity in the vertical direction; at least two groups of the sound generators are unequal in distance from the reflective surface of the synthesis cavity.

[0011] In some embodiments, the sound generator assembly further includes at least two connectors, each corresponding to a sound generator, and the connectors are fixedly connected to the sound generators; the connectors are slidably connected to the fixing component, and the connectors can be fixed relative to the fixing component at at least two positions along the vertical direction.

[0012] In some embodiments, a sensor group is further included, which is electrically connected to the control system; the sensor group is disposed at the top opening of the synthesis chamber; or, the sensor group is disposed inside the synthesis chamber.

[0013] In some embodiments, the sensor group includes at least two acoustic wave sensors, which are arranged sequentially along a vertical direction.

[0014] In some embodiments, the sensor is a piezoelectric sensor or a fiber optic acoustic sensor.

[0015] In some embodiments, the synthesis cavity has a U-shaped structure, and the open end of the U-shaped synthesis cavity corresponds to the sound-emitting end of the sound generator.

[0016] In some embodiments, a power supply system is also included, wherein the speaker group, the control system, and the sensor group are all electrically connected to the power supply system.

[0017] The sound generation system provided in this application includes a support frame and a synthesis cavity disposed inside the support frame. The reflective surface of the synthesis cavity faces the top of the support frame, and both the synthesis cavity and the support frame have a top-open structure so that the sound waves synthesized in the synthesis cavity can be emitted to the outside through the top opening of the support frame. The sound generation unit includes at least two speaker groups, each speaker group including a fixing component. The speaker groups can be adjustablely connected to the top of the support frame via the fixing component, so that at least two speaker groups can move relative to the support frame to adjust the relative position of at least two speaker groups with respect to the synthesis cavity, thereby adjusting the distance between the at least two speaker groups.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

As used in the specification and appended claims of this application, the singular expressions "a," "an," "the," "the," "the," and "this" are intended to also include expressions such as "one or more," unless the context clearly indicates otherwise.

[0024] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0025] like Figure 1 As shown, the sound generation system provided in this application embodiment includes: a support 1, a synthesis cavity 2, a sound generation unit 3, and a control system 4. The synthesis cavity 2 is disposed inside the support 1, with its reflective surface facing the top of the support 1. Both the synthesis cavity 2 and the support 1 have top-opening structures, so that the sound waves synthesized in the synthesis cavity 2 can be emitted to the outside through the top opening of the support 1.

[0026] The sound generating unit 3 includes at least two sound generator groups 30. Each sound generator group 30 includes a fixing component and at least two sound generators. The sound generator group 30 can be adjustedly connected to the top of the support 1 via the fixing component so that the at least two sound generator groups 30 can move relative to the support to adjust the relative position between the at least two sound generator groups 30 and the synthesis cavity 2 to form different layouts that meet the needs of different sound wave environments.

[0027] Each generator group 30 includes at least two generators, and the sound-emitting ends of all generators face the reflective surface of the synthesis cavity 2. The control system 4 is electrically connected to at least two generator groups 30, enabling the control system 4 to adjust parameters such as frequency, amplitude, and phase of the generators in each generator group 30. Thus, by adjusting the layout between at least two generator groups 30 and adjusting the sound wave parameters emitted by at least two generator groups 30, multiple sound waves can be synthesized within the synthesis cavity 2, improving the applicability of the emitted sound waves to meet the needs of various sound wave environments.

[0028] It should be noted that the control system 4 controls each generator group 30 to ensure that the parameters of all generators within the same generator group 30 are consistent. This is achieved by adjusting parameters such as the frequency, amplitude, and phase of the sound waves emitted by the generators; adjusting the amplitude of each generator group 30 to adjust the intensity or loudness of the sound waves; adjusting the phase of each generator group 30, utilizing interference between different phase differences, increasing the intensity of the sound wave in that region through constructive interference and decreasing the intensity through destructive interference; and adjusting the frequency of each generator group 30 to adjust the pitch of the sound waves emitted. In this way, by adjusting the parameters of the sound waves emitted by each generator group 30, different sound waves are synthesized through the superposition of multiple sound wave reflections.

[0029] In the prior art, various parameters of the sound waves emitted by the sound generator can be adjusted through the control system. Therefore, the control system 4 provided in this application embodiment does not involve program improvement.

[0030] It should be noted that the control system 4 provided in this application embodiment can be connected to the sound generator group 30 via wired or wireless means to enable the control system 4 to adjust each sound generator group 30. This application embodiment does not limit this.

[0031] like Figure 1 As shown, since the sound-emitting ends of all the sound generators face the reflective surface of the synthesis cavity 2 in a vertical direction, the synthesis cavity 2 has a U-shaped structure in order to provide a variety of sound wave reflection angles. The open end of the U-shaped structure corresponds to the sound-emitting end of all the sound generators. In this way, the sound waves emitted by different sound generators can form different angles with the reflective surface of the synthesis cavity 2, so that multiple sound waves emitted through the reflective surface can be emitted in different directions, thereby improving the diversity of synthesized sound waves and improving the applicability of the emitted sound waves.

[0032] In the same group of sound generators 30, the fixing component is in the form of a strip structure, and at least two sound generators are linearly distributed along the fixing component of the strip structure; at least two sound generator groups 30 are distributed sequentially along the radial direction of the support 1, and there is a gap between adjacent sound generator groups 30, so that the sound generator groups 30 do not completely block the top opening of the support 1, so that the synthesized sound waves can be emitted to the outside through the top opening of the support 1.

[0033] In some embodiments, the fixing component and the bracket 1 are slidably connected, and one of the fixing component and the bracket 1 is provided with a damper. This allows the gap between adjacent speaker groups 30 to be adjusted by sliding the fixing component, and enables the speaker group 30 to be relatively fixed to the bracket 1 under the action of the damper after being adjusted to a designated position, thereby improving the stability of the sound-generating unit during operation; and, as Figure 1As shown, by adjusting the relative position of the sound generator group 30 along the radial direction of the support 1, the angle between the sound wave emitted by the sound generator and the synthesis cavity 2 can be adjusted, thereby adjusting the direction of the sound wave reflected by each sound generator group 30.

[0034] In other embodiments, the fixing component can also be detachably fixed to the bracket 1 by means of a snap-fit. The fixing component can be snapped to the bracket 1 at multiple positions to adjust the relative position of the fixing component and the bracket 1. At the same time, it can separate the sound generator group 30 from the bracket 1 to change the number of sound generator groups 30 and further improve the applicability of the synthesized sound waves.

[0035] like Figure 1 As shown, in the same group of sound generators 30, all sound generators are equidistant from the reflective surface of the synthesis cavity 2 in the vertical direction; at least two groups of sound generators 30 are unequal in distance from the reflective surface of the synthesis cavity 2. In this way, a multi-layered distribution of sound wave emission points is formed. By adjusting the distance between different groups of sound generators 30 and the synthesis cavity 2, the applicability of the synthesized sound waves can be further improved to further meet the needs of various different sound wave environments.

[0036] To adjust the distance between the sound generator and the synthesis cavity 2, such as Figure 1 As shown, the sound generator assembly 30 also includes at least two connectors 31, each corresponding to a sound generator, and the connectors 31 are fixedly connected to the sound generators so that each sound generator can change the distance between itself and the synthesis cavity 2 by adjusting the connectors; the connectors 31 are slidably connected to the fixing components, and the connectors 31 can be fixed relative to the fixing components at at least two positions in the vertical direction so that the sound generators can be adjusted between at least two positions in the vertical direction to further improve the applicability of the synthesized sound waves.

[0037] In some other embodiments, the connector 31 may be slidably connected to the fixing assembly via a damper to fix the sound generator in a designated position to further adjust the distance between the sound generator and the synthesis cavity 2.

[0038] To ensure that the synthesized sound waves meet the requirements of the specified sound wave environment, the sound generation system provided in this application embodiment also includes a sensor group 6, which is electrically connected to the control system 4. The sensor group 6 can be connected to the control system 4 via wired or wireless means, and this application embodiment does not limit this.

[0039] In some embodiments, the sensor group 6 is disposed at the top opening of the synthesis cavity 2, and can directly detect the parameters of the synthesized sound wave after reflection by the synthesis cavity 2, so as to feed back the parameters of the synthesized sound wave to the control system 4, so that the control system 4 can directly compare whether the synthesized sound wave meets the requirements of the specified sound wave environment.

[0040] In some other embodiments, the sensor group 6 is disposed inside the synthesis cavity 2 so that the sensor group 6 can directly capture the original parameters of each sound wave reflected in the synthesis cavity 2, reduce external environmental noise interference, and feed back the parameters of each sound wave reflected to the control system 4 so that the control system 4 can directly adjust each group of sound generators 30.

[0041] The sensor group 6 includes at least two acoustic wave sensors, which are arranged sequentially along the vertical direction so that the at least two acoustic wave sensors can capture acoustic wave parameters at different heights, so as to detect the vertical distribution characteristics of the acoustic waves.

[0042] In some embodiments, the acoustic sensor may be a piezoelectric sensor, a fiber optic acoustic sensor, etc., and this application does not limit this.

[0043] Sensor group 6 can detect parameters such as sound pressure, sound intensity, and sound velocity of the sound waves within the synthesis cavity 2 to determine the effect of the synthesized sound waves. Specifically, the sound pressure is enhanced or weakened by utilizing constructive and destructive interference from the superposition of sound waves; the energy distribution of the synthesized sound waves is affected by the vector superposition of the sound intensities of multiple sound waves, forming a high-energy focusing region or a low-energy dead region; the sound velocity of each sound wave affects the time delay of sound wave propagation, thereby affecting the phase matching between the sound waves. In this way, by detecting various parameters through sensor group 6, the control system 4 can adjust the sound generator group 30 accordingly to ensure that the synthesized sound waves meet the needs of various different sound wave environments.

[0044] In practice, the sound-generating system provided in this application embodiment also includes a power supply system 5, which provides electrical energy to the control system 4, the sound generator group 30, and the sensor group 6. For example, the power supply system 5 includes a solar panel and an energy storage device connected to the solar panel via a cable, saving costs. The energy storage device, connected to the control system 4, the sound generator group 30, and the sensor group 6 via a cable, can provide a stable voltage, ensuring the stability of the sound wave generation system.

[0045] Of course, power can also be supplied by other power supply systems 5, such as generators, transformers and other power generation equipment. This application embodiment does not limit this.

[0046] When the sound generation system provided in this application embodiment is working, firstly, by adjusting the fixing components, each group of sound generators 30 is placed in a designated position. Then, by adjusting the connecting parts 31 corresponding to the sound generators in each group of sound generators 30, the distance between the sound generators in each group of sound generators 30 and the synthesis cavity 2 is adjusted. Then, the control system 4 controls the parameters of the sound waves emitted by each group of sound generators 30. During the sound wave synthesis process, the sensor group 6 detects the parameters of the sound waves so that the control system 4 can adjust the parameters of the sound waves emitted by each group of sound generators 30 accordingly, so that the synthesized sound waves can meet the requirements of the specified sound wave environment and improve the applicability of the sound waves.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
