Description

Technical Field

[0001] This utility model relates to a speaker, and more particularly to a speaker with a resonance cavity. Background Technology

[0002] Speaker enclosures typically feature loudspeakers to produce sound, and some also incorporate passive radiators. A passive radiator is a diaphragm structure without a driver unit; it vibrates passively based on changes in air pressure within the enclosure. Passive radiators are commonly used to enhance low-frequency response. However, current speaker enclosures with passive radiators exhibit poor stereo sound in low-frequency response, which needs improvement. Utility Model Content

[0003] Therefore, it is necessary to provide a speaker with a resonating cavity that can improve the stereo effect of the speaker in low-frequency response.

[0004] This utility model provides a speaker with a resonance cavity. The speaker includes a cabinet, a sound guide tube, a loudspeaker, and a passive radiator. The cabinet has an inner cavity. The passive radiator is disposed on the side of the cabinet. The sound guide tube is disposed in the cabinet and the sound guide tube and the cabinet are spaced apart to form a resonance cavity. The sound guide tube extends toward the passive radiator and the sound outlet of the sound guide tube is close to and toward the passive radiator. An inlet is provided at the front of the sound guide tube. The loudspeaker is disposed on the cabinet and its front radiating surface faces the front of the cabinet. The rear end of the loudspeaker is inserted into the sound guide tube through the inlet.

[0005] Furthermore, the speaker includes a plurality of speakers arranged side-by-side at intervals along the length of the sound guide tube.

[0006] Furthermore, multiple speakers are arranged side-by-side at intervals along the extended center line of the sound guide tube.

[0007] Furthermore, the speaker includes two passive radiators, one of which is located on the left side of the speaker enclosure and the other on the right side of the speaker enclosure.

[0008] Furthermore, the speaker has a symmetrical structure.

[0009] The present invention has the following beneficial effects: When the speaker of the present invention is working, the loudspeaker vibrates to generate sound. The vibration at the front radiates outward from the front of the speaker, and the sound from the rear passes through the sound guide tube and is conducted to the passive radiator. The passive radiator will resonate, enhancing the low-frequency sound effect. The low-frequency sound will radiate outward to the side, and the sound inside will enter the resonance cavity between the sound guide tube and the cabinet, and further radiate outward through the resonance cavity. This can improve the stereo effect of the speaker in low-frequency response. Attached Figure Description

[0014] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component, or there may be an intervening component. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be noted that, unless otherwise expressly specified and limited, the terms "installed," "connected," and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; as a mechanical connection or an electrical connection; or as a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0015] It should also be noted that in the description of this utility model, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Please see Figures 1-3 As shown, Figure 1 This is a schematic diagram of the speaker 100 of this utility model. Figure 2 This is a schematic diagram of the sound guide tube 12. Figure 3 This is a schematic diagram of the structure of the sound guide tube 12 and the enclosure 11. A specific embodiment of this utility model provides a speaker 100 with a resonance cavity.

[0017] The speaker enclosure 100 includes a cabinet 11, a sound guide tube 12, a loudspeaker 13, and a passive radiator 14. The cabinet 11 has an inner cavity. The passive radiator 14 is disposed on the side 112 or 113 of the cabinet 11. The sound guide tube 12 is disposed inside the cabinet 11, and a resonance cavity 114 is formed between the sound guide tube 12 and the cabinet 11. The sound guide tube 12 extends toward the passive radiator 14, and the sound outlet 122 of the sound guide tube 12 is close to and toward the passive radiator 14. An inlet 121 is provided at the front 123 of the sound guide tube 12. The loudspeaker 13 is disposed on the cabinet 11, and its front radiating surface faces the front 111 of the cabinet 11. The rear end of the loudspeaker 13 is inserted into the sound guide tube 12 through the inlet 121.

[0018] When the speaker 100 of this invention is working, the loudspeaker 13 vibrates to generate sound. The vibration at the front radiates out from the front 111 of the speaker 100, and the sound from the rear passes through the sound guide tube 12 and is conducted to the passive radiator 14. The passive radiator 14 will resonate, enhancing the low-frequency sound effect. The low-frequency sound will radiate to the side, and the sound inside will enter the resonance cavity 114 between the sound guide tube 12 and the cabinet 11, and further radiate to the surroundings through the resonance cavity 114. This can improve the stereo effect of the speaker 100 in low-frequency response.

[0019] In this specific embodiment, the speaker 100 has a left-right symmetrical structure.

[0020] The speaker enclosure 100 includes a plurality of loudspeakers 13, which are arranged side-by-side at intervals along the length of the sound guide tube 12. Specifically, the plurality of loudspeakers 13 are arranged side-by-side at intervals along the extended center line of the sound guide tube 12. In this specific embodiment, the speaker enclosure 100 includes three loudspeakers 13, one high-frequency loudspeaker 13 and two low-frequency loudspeakers 13, which are symmetrically arranged on the left and right sides of the high-frequency loudspeaker 13.

[0021] The speaker 100 includes two passive radiators 14, one of which is located on the left side 112 of the enclosure 11 and the other is located on the right side 113 of the enclosure 11, to further enhance the stereo effect of the speaker 100 in low-frequency response.
