Description

Technical Field

[0001] This utility model relates to a speaker, and more particularly to a speaker capable of producing a variety of different sound effects. Background Technology

[0002] A speaker is a device that converts audio into sound, which is radiated into space. It primarily relies on the speakers on the speaker enclosure to emit sound. The speaker enclosure enhances and modulates the sound output through its internal cavity. This internal cavity, through resonance, amplifies the sound waves generated by the diaphragm, making the sound louder. Furthermore, by changing the size of the internal cavity, the timbre and pitch of the sound can be adjusted. Therefore, the internal cavity of the speaker enclosure is crucial. In current technology, the size of the internal cavity of a speaker enclosure is fixed, thus the sonic signature remains constant. Utility Model Content

[0003] Therefore, it is necessary to provide a speaker that can generate a variety of different sound effects and reduce noise.

[0004] This utility model provides a speaker capable of producing a variety of different sound effects, the speaker comprising:

[0005] The housing is divided into a first chamber and a second chamber by a partition;

[0006] A first phase inverter tube is disposed on the partition and connects the first chamber and the second chamber;

[0007] A loudspeaker, the loudspeaker being mounted in the first chamber;

[0008] The second phase inverter tube is installed in the second chamber;

[0009] An opening and closing mechanism is provided, comprising a first motor, a sealing plate, and a second motor. The first motor is connected to the sealing plate to drive the sealing plate to rotate, thereby closing the first phase inverter tube, closing the second phase inverter tube, or simultaneously opening the first phase inverter tube and the second phase inverter tube. The second motor is connected to the first motor to drive the first motor and the sealing plate to rotate together. The rotation direction of the first motor is perpendicular to the rotation direction of the second motor.

[0010] Furthermore, the sealing plate is provided with a through-hole corresponding to the positions of the first phase inverter and the second phase inverter, and a passive diaphragm is provided at the through-hole. When the sealing plate closes the first phase inverter, the passive diaphragm is located at the opening of the first phase inverter, and when the sealing plate closes the second phase inverter, the passive diaphragm is located at the opening of the second phase inverter.

[0011] Furthermore, the through-hole is provided with two passive diaphragms, including a first passive diaphragm and a second passive diaphragm, wherein the first passive diaphragm is located on the first side of the sealing plate, and the second passive diaphragm is located on the second side of the sealing plate, wherein the first side and the second side are opposite to each other.

[0012] Furthermore, the passive diaphragm is connected to the sealing plate via its edge.

[0013] Furthermore, when the sealing plate closes the first phase inverter, the edge of the first passive diaphragm seals the gap between the sealing plate and the first phase inverter; when the sealing plate closes the second phase inverter, the edge of the second passive diaphragm seals the gap between the sealing plate and the second phase inverter.

[0014] Furthermore, the sealing plate is a flat plate, and the first motor is fixed to the sealing plate.

[0015] Furthermore, the rotation direction of the first motor is parallel to the axial direction of the first phase inverter.

[0016] This invention has the following beneficial effects: The first motor rotates the sealing plate, causing it to close the first bass reflex tube, close the second bass reflex tube, or simultaneously open both. When the sealing plate closes the first bass reflex tube, the speaker relies on the first chamber to enhance and adjust the sound output. When the sealing plate closes the second bass reflex tube, the speaker relies on both the first and second chambers to enhance and adjust the sound output. When the sealing plate simultaneously opens both the first and second bass reflex tubes, the speaker becomes a bass-reflex speaker. Furthermore, the second motor can rotate the sealing plate to minimize its distance from the sound transmission channel between the first and second bass reflex tubes, thus reducing noise from the sealing plate, making the sound clearer, and improving the speaker's sound quality.

[0024] Please see Figures 1-2 As shown in the figure, a specific embodiment of this utility model provides a speaker 100 capable of producing various sound effects. The speaker 100 includes a cabinet 10, a speaker 20, a first bass reflex port 30, a second bass reflex port 40, and an opening and closing mechanism 50. The cabinet 10 is provided with multiple control buttons 11 and a handle 12. The cabinet 10 has an internal cavity, which is divided into a first chamber 101 and a second chamber 102 by a partition 13.

[0025] The speaker 20 is installed in the first chamber 101, the first bass reflex tube 30 is disposed on the partition 13 and connects the first chamber 101 and the second chamber 102, the second bass reflex tube 40 is installed in the second chamber 102, one end of the second bass reflex tube 40 is connected to the second chamber 102, and the other end is connected to the outside of the second chamber 102.

[0026] See also Figures 2-4 As shown, the opening and closing mechanism 50 includes a first motor 51, a sealing plate 53, and a second motor 52. The first motor 51 is connected to the sealing plate 53 to drive the sealing plate 53 to rotate, so that the sealing plate 53 closes the first phase inverter tube 30 or closes the second phase inverter tube 40, or simultaneously opens the first phase inverter tube 30 and the second phase inverter tube 40. The second motor 52 is connected to the first motor 51 to drive the first motor 51 and the sealing plate 53 to rotate together. The rotation direction of the first motor 51 is perpendicular to the rotation direction of the second motor 52.

[0027] When the sealing plate 53 closes the first bass reflex tube 30, the speaker 100 relies on the first chamber 101 to enhance and adjust the sound output. When the sealing plate 53 closes the second bass reflex tube 40, the speaker 100 relies on the first chamber 101 and the second chamber 102 to enhance and adjust the sound output. When the sealing plate 53 simultaneously opens the first bass reflex tube 30 and the second bass reflex tube 40, the speaker 100 becomes a bass reflex speaker 100. At this time, the second motor 52 can be used to rotate the sealing plate 53 so that the sealing plate 53 avoids the sound transmission space between the first bass reflex tube 30 and the second bass reflex tube 40 as much as possible. This reduces the noise of the sealing plate 53, makes the sound clearer, and improves the sound quality of the speaker 100.

[0028] The sealing plate 53 has through openings 531 corresponding to the positions of the first bass reflex tube 30 and the second bass reflex tube 40, and a passive diaphragm 54 is provided at the through opening 531. When the sealing plate 53 closes the first bass reflex tube 30, the passive diaphragm 54 is located at the opening of the first bass reflex tube 30. When the speaker 20 is working, the air pressure change in the first chamber 101 will cause the passive diaphragm 54 to vibrate passively, thereby improving the low-frequency response when only the first chamber 101 acts as a resonant cavity. When the sealing plate 53 closes the second bass reflex tube 40, the passive diaphragm 54 is located at the opening of the second bass reflex tube 40. When the speaker 20 is working, the air pressure change in the second chamber 102 will cause the passive diaphragm 54 to vibrate passively, thereby improving the low-frequency response when both the first chamber 101 and the second chamber 102 act as resonant cavities. Therefore, providing the passive diaphragm 54 on the sealing plate 53 can enhance the low-frequency response of both sound effects.

[0029] In this specific embodiment, two passive diaphragms 54 are provided at the through-hole 531, namely a first passive diaphragm 541 and a second passive diaphragm 542. The first passive diaphragm 541 is located on the first surface of the sealing plate 53, and the second passive diaphragm 542 is located on the second surface of the sealing plate 53, wherein the first surface and the second surface are opposite to each other. During vibration, both passive diaphragms 54 vibrate simultaneously. Specifically, when the sealing plate 53 closes the first phase inverter 30, the first passive diaphragm 541 acts as the main diaphragm, and the second passive diaphragm 542 assists in vibration. When the sealing plate 53 closes the second phase inverter 40, the second passive diaphragm 542 acts as the main diaphragm, and the first passive diaphragm 541 assists in vibration, thus ensuring the vibration effect of the passive diaphragms 54.

[0030] The passive diaphragm 54 is connected to the sealing plate 53 via an edge 501. When the sealing plate 53 closes the first phase inverter 30, the edge 501 of the first passive diaphragm 541 seals the gap between the sealing plate 53 and the first phase inverter 30. When the sealing plate 53 closes the second phase inverter 40, the edge 501 of the second passive diaphragm 542 seals the gap between the sealing plate 53 and the second phase inverter 40. The first passive diaphragm 541 and the second passive diaphragm 542 can both provide auxiliary vibration and seal the gap.

[0031] In this embodiment, the sealing plate 53 is a flat plate, and the first motor 51 is fixed on the sealing plate 53. In this embodiment, the rotation direction of the first motor 51 is parallel to the axis of the first bass reflex tube 30. By first controlling the rotation of the second motor 52 and then controlling the rotation of the first motor 51, the sealing plate 53 can avoid the sound transmission space channel between the first bass reflex tube 30 and the second bass reflex tube 40 as much as possible.

Conversely, some features of this invention are described only in a single embodiment for brevity; however, these features may also be described individually or in any suitable combination in different embodiments.
