Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a loudspeaker with a collision protection structure. Background Technology

[0002] In the field of audio equipment, the safety and stability of the speaker, as the core sound-producing component, have always been key considerations in the design and use process. In scenarios where it may be subjected to collisions or external impacts, the speaker cone area is very easy to be damaged by direct impact, resulting in a decrease in sound performance or even failure.

[0003] Currently, the protective structure of traditional loudspeakers usually takes the form of fixed grilles or baffles. However, these structures have obvious drawbacks: on the one hand, the fixed protective structure will block the sound output of the loudspeaker during normal use, affecting the normal propagation of sound waves and resulting in damage to sound quality; on the other hand, when the loudspeaker is subjected to a frontal collision or external impact, the fixed protective structure cannot effectively absorb the impact energy through its own deformation, and can only withstand the external force through rigid blocking, which is difficult to form substantial buffer protection for the loudspeaker cone area, and the protective effect is limited. Utility Model Content

[0004] This utility model relates to a loudspeaker with a collision protection structure, which solves the problems of traditional loudspeakers using fixed grilles or baffles as protective structures, which block sound production and affect sound quality during normal use, and cannot effectively absorb energy through deformation when impacted, thus having limited buffering protection for the cone area.

[0005] This utility model provides a loudspeaker with a collision protection structure, specifically including: a loudspeaker, two upper rotating seats are fixedly installed symmetrically on the left and right sides of the front end face of the loudspeaker mounting plate, and the left and right ends of the upper rotating seats are provided with an upper shaft hole; a semi-circular upper protective plate is provided in the upper half area of ​​the front side of the loudspeaker, and an upper rotating mating plate is fixedly installed on the top of the outer periphery of the upper protective plate. The top of the upper rotating mating plate adopts a semi-circular structure, and an upper rotating shaft is fixedly installed at the axial center of the left end face and the axial center of the right end face of the upper rotating mating plate. The two upper rotating shafts are rotatably connected to the two upper shaft holes respectively; an upper torsion spring is sleeved around the two upper rotating shafts. One end of the upper torsion spring is fixedly connected to the upper rotating seat, and the other end of the upper torsion spring is fixedly connected to the upper rotating mating plate; in the natural state, the front end face of the upper protective plate is set at an 85-degree angle to the front end face of the loudspeaker mounting plate.

[0006] Furthermore, two lower rotating seats are fixedly installed symmetrically on the lower side of the front end face of the speaker mounting plate, and a lower shaft hole is opened on both the left and right end faces of the lower rotating seats; a lower protective plate with a semi-circular structure is provided in the lower half area of ​​the front side of the speaker, and a lower rotating mating plate is fixedly installed on the bottom of the outer circumference of the lower protective plate. The bottom end of the lower rotating mating plate adopts a semi-circular structure, and a lower rotating shaft is fixedly installed at the axial center of the left end face and the axial center of the right end face of the lower rotating mating plate. The two lower rotating shafts are rotatably connected to the two lower shaft holes respectively.

[0007] Furthermore, a lower torsion spring is sleeved around each of the two lower rotating shafts. One end of the lower torsion spring is fixedly connected to the lower rotating seat, and the other end of the lower torsion spring is fixedly connected to the lower rotating mating plate. In its natural state, the front end face of the upper protective plate is set at an 85-degree angle to the front end face of the speaker mounting plate.

[0008] Furthermore, the bottom and rear faces of the upper protective plate share an upper inclined cut surface; the top and rear faces of the lower protective plate share a lower inclined cut surface; the rear face of the upper protective plate has an upper protective groove with a semi-circular groove structure that penetrates the upper inclined cut surface; the rear face of the lower protective plate has a lower protective groove with a semi-circular groove structure that penetrates the lower inclined cut surface.

[0009] Furthermore, when the bottom end of the upper protective plate is in contact with the top end of the lower protective plate, the upper and lower protective plates completely cover and block the cone area of ​​the speaker, while the upper and lower torsion springs are both in a torsional deformation state.

[0010] Furthermore, a T-shaped shaft groove is provided on the lower side of the front end face of the upper protective plate; a limiting plate with a circular plate structure is provided on the front side of the upper protective plate, and a T-shaped shaft is fixedly installed at the axial center of the rear end face of the limiting plate, and the T-shaped shaft is rotatably connected to the T-shaped shaft groove.

[0011] Furthermore, a rectangular limiting block is fixedly installed on the side of the front end face of the lower protective plate, and a limiting slot with an arc-shaped groove structure is opened on the top surface of the limiting block; a disengagement cutting surface is opened on the outer peripheral surface of the limiting insert plate; when the disengagement cutting surface faces upward, the limiting insert plate is structurally limited and inserted into the limiting slot, and when the disengagement cutting surface faces downward, the limiting insert plate disengages from the limiting slot.

[0012] This utility model provides a loudspeaker with a collision protection structure, which has the following beneficial effects:

[0013] In normal application, this invention provides initial support for the upper and lower protective plates via upper and lower torsion springs, allowing the front ends of both plates to unfold at an 85-degree angle to the front end of the speaker mounting plate. The protective plates are horizontally unfolded, ensuring they do not obstruct the speaker cone area and guaranteeing normal speaker operation. In this state, when the speaker is subjected to a frontal collision or external impact, the unfolded upper and lower protective plates rotate around their respective axes towards the speaker cone. The upper and lower torsion springs simultaneously undergo torsional deformation, absorbing impact energy through elastic deformation and storing it as elastic potential energy, forming a buffer mechanism. This effectively attenuates the direct impact of external forces on the speaker. Furthermore, during impact, the upper and lower protective plates simultaneously cover the speaker cone area, providing anti-collision protection for the speaker cone.

[0014] When the speaker is not in use, the upper and lower protective plates can be rotated and closed to cover the speaker cone area, forming a closed protective structure to prevent the cone area from being damaged by impact. By rotating the limiting plate, the outer circumferential cut surface of the limiting plate faces upward, and a part of the limiting plate is inserted into the limiting matching slot to form a mechanical lock, preventing the upper and lower protective plates from automatically returning to their original positions due to spring force, ensuring the stability of the closed protective state. When it is necessary to unfold the protective plate, the limiting plate is manually rotated so that the cut surface faces downward, the limiting plate disengages from the limiting matching slot, and the mechanical lock is released. Under the restoring action of the upper and lower torsion springs, the protective plate can automatically return to its initial 85-degree unfolded state, making operation convenient.

The opening of the upper inclined cut surface 206 and the lower inclined cut surface 304 facilitates that when the upper protective plate 2 and the lower protective plate 3 are rotated and unfolded in the closed state, the bottom end of the upper protective plate 2 and the top end of the lower protective plate 3 will not cause contact obstruction; an upper protective groove 209 with a semi-circular groove structure is provided on the rear end face of the upper protective plate 2, and the upper protective groove 209 penetrates the upper inclined cut surface 206; a lower protective groove 305 with a semi-circular groove structure is provided on the rear end face of the lower protective plate 3, and the lower protective groove 305 penetrates the lower inclined cut surface 304.When the bottom end of the upper protective plate 2 is in contact with the top end of the lower protective plate 3, the upper protective plate 2 and the lower protective plate 3 completely cover and block the cone area of ​​the speaker 1, while the upper torsion spring 203 and the lower torsion spring 303 are both in a state of torsional deformation.

[0030] In this embodiment, a T-shaped shaft groove 207 is provided on the lower side of the front end face of the upper protective plate 2; a circular plate-shaped limiting insert 204 is provided on the front side of the upper protective plate 2, and a T-shaped shaft 208 is fixedly installed at the axial center of the rear end face of the limiting insert 204, and the T-shaped shaft 208 is rotatably connected to the T-shaped shaft groove 207; a rectangular block-shaped limiting mating block 306 is fixedly installed on the upper side of the front end face of the lower protective plate 3, and an arc-shaped groove-shaped limiting mating slot 307 is provided on the top surface of the limiting insert 204; a disengagement cutting surface 205 is provided on the outer peripheral surface of the limiting insert 204; when the disengagement cutting surface 205 faces upward, the limiting insert 204 is structurally limited and inserted into the limiting mating slot 307; when the disengagement cutting surface 205 faces downward, the limiting insert 204 disengages from the limiting mating slot 307.

[0031] The working principle of this embodiment:

[0032] In the natural state of the upper torsion spring 203 and the lower torsion spring 303 (i.e., the upper torsion spring 203 and the lower torsion spring 303 have not undergone torsional deformation, and they provide initial support force for the upper protective plate 2 and the lower protective plate 3), the front end faces of the upper protective plate 2 and the lower protective plate 3 are both unfolded at an 85-degree angle to the front end face of the speaker 1 mounting plate, that is, the protective plates are in a horizontal unfolded state, without obstructing the cone area of ​​the speaker 1, ensuring that the speaker 1 can produce sound normally;

[0033] When the speaker 1 is subjected to a collision or external force impact in actual application, the upper protective plate 2 and the lower protective plate 3, which are in the unfolded state, will be subjected to external force. This external force forces the upper protective plate 2 and the lower protective plate 3 to rotate around their respective rotation axes in the direction of the speaker 1 cone. During the rotation, the upper torsion spring 203 and the lower torsion spring 303 simultaneously generate torsional deformation, absorb the impact energy through elastic deformation and convert it into elastic potential energy for storage, thereby forming a buffer mechanism to effectively attenuate the direct impact of external force on the speaker 1. Moreover, based on the rotation of the upper protective plate 2 and the lower protective plate 3 in the direction of the speaker 1 cone, the upper protective plate 2 and the lower protective plate 3 simultaneously cover the cone area of ​​the speaker 1 during the impact process to achieve anti-collision protection for the cone area of ​​the speaker 1.

[0034] When the speaker 1 is not in use, to prevent damage to the cone area of ​​the speaker 1 from impact, the upper protective plate 2 and the lower protective plate 3 can be rotated to close, so that the upper protective plate 2 and the lower protective plate 3 together cover the cone area of ​​the speaker 1, forming a closed protective structure. Then, the limiting insert 204 is rotated so that the disengagement cut surface 205 of its outer circumference faces upward. At this time, part of the limiting insert 204 is inserted into the limiting engagement slot 307, forming a mechanical lock, thereby preventing the upper protective plate 2 and the lower protective plate 3 from automatically springing back to their original positions due to the spring force. When it is necessary to rotate and unfold the upper protective plate 2 and the lower protective plate 3, simply rotate the limiting insert 204 manually so that the disengagement cut surface 205 faces downward. At this time, the limiting insert 204 disengages from the limiting engagement slot 307, thereby releasing the mechanical lock. At this time, under the reset spring of the upper torsion spring 203 and the lower torsion spring 303, the upper protective plate 2 and the lower protective plate 3 will be driven to rotate in the opposite direction around the pivot, returning to the initial 85-degree unfolded state.
