Description

Technical Field

[0001] This utility model relates to the field of audio technology, specifically to a panoramic surround sound system. Background Technology

[0002] Early surround sound systems were based on planar surround layouts, such as 5.1 (5 speakers + 1 subwoofer) or 7.1 channels (7 speakers + 1 subwoofer). While these systems could provide sound field localization in the left-right and front-back directions, they lacked sound performance in the vertical direction (height axis), resulting in insufficient immersion.

[0003] Existing immersive surround sound systems break away from the traditional 5.1 / 7.1 planar surround sound by incorporating floor speakers, subwoofers, and ceiling channels. This allows for height-axis positioning via the ceiling channels, enabling each sound effect to have its three-dimensional coordinates freely set, thus enhancing the user experience. However, existing immersive surround sound systems can only be used as a single, complete system, lacking flexibility and failing to meet diverse user needs. Utility Model Content

[0004] To address the aforementioned problems, this invention proposes a panoramic sound surround system.

[0005] This utility model provides a panoramic sound surround system for generating surround sound in a target space. The system includes a speaker base, surround speaker modules, and a subwoofer. The speaker base control unit is connected to the surround speaker modules and the subwoofer.

The input terminal of the switching circuit is electrically connected to a power supply, and the output terminal of the switching circuit is electrically connected to the receiving terminal of the speaker host control unit. The controlled terminal of the switching circuit is detachably wired to the control terminal of the speaker base control unit.

[0006] Beneficial effects:

[0007] This invention features a speaker unit comprising a main speaker, a control unit, and a switching circuit. The control unit is electrically connected to the main speaker, allowing it to drive the speaker. The switching circuit's input is connected to a power source, and its output is connected to the receiving end of the control unit. The controlled end of the switching circuit is detachably wired to the control end of the speaker base control unit. Therefore, when the control end of the speaker base control unit is wired to the controlled end of the switching circuit, the main speaker, surround speaker modules, and subwoofer can be combined to form a complete surround sound system. When the control end of the speaker base control unit is not wired to the controlled end of the switching circuit, the main speaker control unit can drive the main speaker independently, allowing the speaker unit to function as an independent channel speaker. The speaker base control unit can also independently drive the surround speaker modules and subwoofer to function as a surround sound system lacking one channel.

It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this application.

Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this application.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

[0025] like Figure 1 As shown, this utility model provides a panoramic sound surround system for generating surround sound in a target space, comprising a speaker base, a surround speaker module, and a subwoofer. The speaker base control unit of the speaker base is connected to the surround speaker module and the subwoofer. The system also includes a speaker host, which includes:

[0026] Main unit speaker;

[0027] A speaker unit control unit, which is electrically connected to the speaker unit;

[0028] The switching circuit has its input terminal electrically connected to the power supply, its output terminal electrically connected to the receiving terminal of the audio host control unit, and its controlled terminal detachably wiredly connected to the control terminal of the audio base control unit.

[0029] This embodiment features a main audio unit equipped with a main speaker, a main audio unit control unit, and a switching circuit. Since the main audio unit control unit is electrically connected to the main speaker, it can drive the main speaker. The input of the switching circuit is electrically connected to the power supply, and its output is electrically connected to the receiving end of the main audio unit control unit. The controlled end of the switching circuit is detachably wired to the control end of the speaker base control unit. Therefore, when the control end of the speaker base control unit is wired to the controlled end of the switching circuit, the main speaker, surround speaker modules, and subwoofer can be combined to form a complete surround sound system. When the control end of the speaker base control unit is not wired to the controlled end of the switching circuit, the main audio unit control unit can drive the main speaker independently, allowing the main audio unit to be used as an independent channel speaker. The speaker base control unit can also independently drive the surround speaker modules and subwoofer to form a surround sound system lacking one channel. Therefore, the surround sound system provided by this technical solution offers at least three usage modes, improving system flexibility and meeting different user needs.

[0030] like Figure 2 As shown, the switching circuit includes a switching unit, the first end of which is electrically connected to the power supply, the second end of which is the controlled end of the switching circuit, and the third end of which is electrically connected to the receiving end of the audio host control unit.

[0031] Specifically, when the speaker base outputs a control signal to the second terminal of the switching circuit, the first and second terminals of the switching unit are connected. This allows the receiver of the speaker head unit control system to receive the power supply level signal, enabling the speaker head unit control system to know that the controlled terminal of the switching circuit is connected to the control terminal of the speaker base control system. At this point, the control logic for a complete surround sound system can be switched and combined. If the receiver of the speaker head unit control system does not receive the power supply level signal, it indicates that the two are not connected. Therefore, this embodiment provides a hardware foundation that helps improve the flexibility of the surround sound system and meet different user needs.

[0032] like Figure 2 As shown, the switching unit includes a transistor Q1, a first resistor R1, and a second resistor R2. The emitter of the transistor Q1 is electrically connected to the power supply and the first terminal of the first resistor R1. The base of the transistor Q1 is electrically connected to the second terminal of the first resistor R1 and the first terminal of the second resistor R2. The collector of the transistor Q1 is electrically connected to the receiving terminal of the audio host control unit. The second terminal of the second resistor R2 is the controlled terminal of the switching circuit.

[0033] Specifically, when the controlled terminal of the switching circuit is connected to the control terminal of the speaker base control unit, the control terminal of the speaker base control unit outputs a low level to the base of the transistor, controlling the transistor Q1 to conduct. The electrical signal received by the receiving terminal of the speaker host control unit changes from low level to high level. The speaker host control unit then determines that the controlled terminal of the switching circuit is connected to the control terminal of the speaker base control unit, and will then combine the speaker host, surround speaker module, and subwoofer into a complete panoramic surround sound system.

[0034] Preferably, the switching circuit further includes a diode D1, the anode of which is electrically connected to the power supply, and the cathode of which is electrically connected to the first terminal of the switching unit.

[0035] Preferably, the switching circuit further includes a filtering unit, the first end of which is electrically connected to the third end of the switching unit and the receiving end of the audio host control unit, and the second end of the filtering unit is grounded.

[0036] Preferably, the filtering unit includes a third resistor and a first capacitor connected in parallel. The first end of the third resistor and the first end of the first capacitor are electrically connected to the third end of the switching unit and the receiving end of the audio host control unit. The second end of the third resistor and the second end of the first capacitor are grounded.

[0037] Preferably, the main unit speaker includes at least a first speaker located on the left side of the main unit housing, a speaker located on the right side of the main unit housing, and a speaker located in the middle of the main unit housing.

[0038] Preferably, the surround speaker module includes at least a front left ground speaker, a front right ground speaker, a front left sky speaker, a front right sky speaker, a rear left ground speaker, a rear right ground speaker, a rear left sky speaker, and a rear right sky speaker. Thus, when the controlled terminal of the switching circuit is connected to the control terminal of the speaker base control unit, a 6.1.4 immersive surround sound system can be formed; when not connected, the surround speaker module and the subwoofer can form a 4.1.4 immersive surround sound system.

[0039] Preferably, the surround speaker module includes a front left ground speaker, a front right ground speaker, a front left sky speaker, a front right sky speaker, a rear left ground speaker, a rear right ground speaker, a rear left sky speaker, a rear right sky speaker, and a front center ground speaker. Thus, when the controlled terminal of the switching circuit is connected to the control terminal of the speaker base control unit, a 7.1.4 surround sound system can be formed; when not connected, the surround speaker module and the subwoofer can form a 4.1.4 surround sound system.

[0040] Preferably, both the main unit housing of the speaker host and the base housing of the speaker base are provided with socket-type pin headers, and the controlled terminal of the switching circuit and the control terminal of the speaker base control unit are detachably wired connected via the socket-type pin headers.

[0041] It should be noted that the terms "horizontal" and "vertical" do not imply that the components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. Similarly, the terms "parallel" and "perpendicular" do not imply that the components are absolutely parallel or perpendicular, but rather that they can have a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but rather that it can be slightly tilted. Furthermore, the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0042] It is understood that the term "multiple" in this document means at least two, such as two, three, etc., unless otherwise specified. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. The term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects are in an "or" relationship.

[0043] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
