Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sound equipment technology, specifically relating to a speaker enclosure and speaker box. Background Technology
[0002] When a subwoofer is working, the reciprocating motion of the composite cone does work on the air inside the cabinet. The air expands due to heat, causing the composite cone to bulge and deform. To prevent this deformation, a vent hole is provided on the cabinet to connect to the outside. However, this vent hole generates airflow noise, which interferes with the speaker's sound quality. Utility Model Content

[0028] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
[0029] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.
[0030] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.
[0031] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations.
[0032] When a subwoofer is operating, the reciprocating motion of the cone does work on the air inside the cabinet, causing the air to expand due to heat, leading to cone deformation. To prevent this deformation, a vent hole is installed on the cabinet to connect to the outside. However, this vent hole generates airflow noise, interfering with the speaker's sound quality. To eliminate this noise, a mesh made of sound-absorbing material is attached to the vent hole to increase damping and reduce airflow speed. However, this mesh increases the BOM cost and adds a workstation during assembly.
[0033] Figure 1 A schematic cross-sectional view of a speaker according to an embodiment of the present invention is shown. Figure 2 for Figure 1 An enlarged sectional view of section A in the middle. (See image.) Figure 1 and 2As shown, this utility model proposes a speaker enclosure and speaker cabinet for a speaker 200. The speaker enclosure 200 of this utility model includes an enclosure body 10, which has a receiving cavity 11. The enclosure body 10 has a mounting hole communicating with the receiving cavity 11 for mounting the speaker 200. The enclosure body 10 also has a vent hole 14 communicating with the receiving cavity 11 and the outside of the enclosure body 10. The vent hole 14 includes a first hole portion 141 and a second hole portion 142 communicating with each other. Along the arrangement direction of the first hole portion 141 and the second hole portion 142 (e.g., ...), the vent hole 14 is provided with a vent hole 14. Figure 2 As shown, the orthographic projection of the first hole 141 or the orthographic projection of the second hole 142 partially overlaps.
[0034] By using the speaker 200 enclosure in this technical solution, the mounting hole is used to install the speaker 200, the vent hole 14 is used to balance the air pressure between the receiving cavity 11 and the outside, and the orthographic projection of the first hole 141 and the orthographic projection of the second hole 142 are overlapped, so that the airflow from the first hole 141 to the second hole 142 will be suppressed, thereby blocking and reflecting the airflow at the vent hole 14, greatly reducing the flow velocity and reducing airflow noise.
[0035] Specifically, in this embodiment, the first hole 141 is located on the side of the second hole 142 facing the receiving cavity 11. The first hole 141 and the second hole 142 are connected, and the first hole 141 and the second hole 142 are arranged along the axial direction of the first hole 141. The receiving cavity 11 can be connected to the second hole 142 through the first hole 141, and the second hole 142 is connected to the outside of the speaker 200 enclosure, thus realizing the communication between the outside of the speaker 200 enclosure and the receiving cavity 11.
[0036] In some embodiments of this utility model, such as Figure 3 As shown, the vent 14 also includes a third vent 143. The first vent 141 is located on the side of the second vent 142 facing the receiving cavity 11, and the third vent 143 is located on the side of the second vent 142 away from the receiving cavity 11. The second vent 142 connects the first vent 141 and the third vent 143, along the arrangement direction of the second vent 142 and the third vent 143 (e.g., ...). Figure 3As shown, the orthographic projections of the second hole 142 and the third hole 143 partially overlap (i.e., along the axial direction of the third hole 143 or the axial direction of the second hole 142). In this embodiment, the vent 14 is provided with a three-step hole combination structure. Since the orthographic projections of the second hole 142 and the third hole 143 partially overlap along the arrangement direction of the second hole 142 and the third hole 143, the airflow from the second hole 142 to the third hole 143 is further suppressed by the cooperation of the first hole 141 and the second hole 142. This further blocks and reflects the airflow at the vent 14, and significantly reduces the flow velocity and airflow noise.
[0037] Specifically, in this embodiment, the number of holes can be increased. As long as the orthographic projections of adjacent holes overlap, the airflow can be suppressed and blocked when flowing through adjacent holes, thereby reducing flow velocity and airflow noise.
[0038] In some embodiments of this utility model, such as Figure 3 As shown, along the arrangement direction of the first hole 141 and the second hole 142, the orthographic projection of the third hole 143 onto the second hole 142 partially overlaps with the orthographic projection of the first hole 141 onto the second hole 142. In this embodiment, the above arrangement facilitates the manufacturability of the first hole 141, the second hole 142, and the third hole 143, that is, it allows for easy manufacturing and processing of the first hole 141, the second hole 142, and the third hole 143 using ordinary hole machining methods, thereby improving reliability.
[0039] In some embodiments of this utility model, the diameter range of the first hole 141, the second hole 142, and the third hole 143 is 1mm-10mm. In this embodiment, the diameters of the first hole 141, the second hole 142, and the third hole 143 should be within the above-mentioned range. If the diameter is too large, the airflow velocity through the holes may exceed a critical value, further causing turbulent noise. If the diameter is too small, the air pressure in the second cavity 12 cannot be balanced in time, forming a "barotrapping" effect. Furthermore, if the vent 14 is too small, the heat dissipation airflow is obstructed, leading to an increase in temperature and affecting the sound quality of the speaker.
[0040] In some embodiments of this utility model, such as Figure 3As shown, the axis of the third hole 143 is located on the side of the axis of the second hole 142 that is opposite to the axis of the first hole 141. In this embodiment, the axis of the third hole 143 and the axis of the first hole 141 are located on opposite sides of the axis of the second hole 142. In this case, it is necessary to ensure that the orthographic projection of the third hole 143 on the second hole 142 and the orthographic projection of the first hole 141 on the second hole 142 partially coincide. This ensures that the vent hole 14 can be processed, thus improving reliability.
[0041] In some embodiments of this utility model, the axis of the first hole 141 and the axis of the third hole 143 are both located on the same side of the axis of the second hole 142. In this embodiment, along the arrangement direction of the first hole 141 and the second hole 142, the orthographic projection of the third hole 143 can coincide with the orthographic projection of the first hole 141, thus satisfying both the partial coincidence of the orthographic projections of the first hole 141 and the second hole 142, and the partial coincidence of the orthographic projections of the third hole 143 and the second hole 142.
[0042] In some embodiments of this utility model, such as Figure 1 As shown, the speaker 200 enclosure also includes a mesh 20, which is attached to the side of the vent 14 facing away from the receiving cavity 11. In this embodiment, a mesh 20 made of sound-absorbing material is attached to the vent 14 to increase damping and reduce airflow velocity. The combination structure of the multiple pores in the vent 14 further increases damping and reduces airflow velocity, thereby improving reliability.
[0043] In some embodiments of this utility model, such as Figure 1 As shown, along the arrangement direction of the vent holes 14 and the mesh fabric 20, the orthographic projection of the vent holes 14 toward the mesh fabric 20 is located within the mesh fabric 20. In this embodiment, the above arrangement ensures that the mesh fabric 20 completely covers the vent holes 14, thereby allowing the airflow flowing out of the vent holes 14 to be absorbed by the mesh fabric 20, thus improving reliability.
[0044] This utility model also proposes a speaker, such as Figure 1 As shown, it includes:
[0045] The speaker 200 enclosure is the speaker 200 enclosure described above;
[0046] Speaker 200, speaker 200 is provided in the mounting hole.
[0047] By using the speaker enclosure in this technical solution, the speaker 200 is used to produce sound, the mounting hole of the speaker 200 enclosure is used to install the speaker 200, and the vent 14 is used to balance the air pressure between the receiving cavity 11 and the outside. The orthographic projection of the first hole 141 and the orthographic projection of the second hole 142 overlap, so that the airflow from the first hole 141 to the second hole 142 will be suppressed, thereby blocking and reflecting the airflow at the vent 14, greatly reducing the flow velocity and reducing airflow noise.
[0048] In some embodiments of this utility model, such as Figure 1 As shown, the speaker enclosure also includes a reinforcing rib 13. The enclosure body 10 has a first inner wall 121 and a second inner wall 122 arranged along the height direction of the speaker enclosure. The opposite ends of the reinforcing rib 13 are connected to the first inner wall 121 and the second inner wall 122, respectively. In this embodiment, the reinforcing rib 13 can strengthen the overall strength of the speaker enclosure and improve its stability. The reinforcing rib 13 can be plate-shaped or rod-shaped, and it is arranged along the height direction of the speaker enclosure. A through hole 131 can be provided on the reinforcing rib 13 to connect the mounting hole and the vent hole 14 inside the enclosure body 10.
[0049] The above description of the receiving cavity 11 is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
