Description

Technical Field

[0001] The present invention relates to the technical field of loudspeakers, in particular to a vocal loudspeaker with lights. Background Art

[0002] A loudspeaker, also known as a speaker or horn, is a transducer device that converts electrical signals into sound signals. It is mainly used in teaching, guiding, outdoor activities or other daily life.

[0003] Loudspeakers, as a type of vocal music playback device, often incorporate light-emitting units to enhance the entertainment experience. These units emit dazzling light effects during music playback. Existing loudspeaker devices with light-emitting units typically feature a cavity defined on a mounting panel, housing the loudspeaker unit and a controller. The light-emitting unit is then mounted against the inner wall of the cavity, with the controller controlling the loudspeaker unit's playback and illumination. This installation method not only easily compromises the light-emitting unit's heat dissipation, but can also cause the eardrum to exceed its vibration range and be damaged when the volume is high or when there is significant external interference. Therefore, the present invention proposes a vocal loudspeaker with light. Summary of the Invention

[0004] The object of the present invention is to provide a vocal amplifier with lights to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a vocal amplifier with lights, comprising a mounting panel, a sound amplification port being provided on the mounting panel, a loudspeaker body and a light strip being installed on the right side of the sound amplification port, the loudspeaker body comprising a basin, a tympanum being provided on the left portion of the basin, a first elastic metal ring and a second elastic metal ring being provided at the inner circle of the left portion of the basin respectively in the left and right directions, the tympanum fixing clamp being provided between the first elastic metal ring and the second elastic metal ring, a baffle being fixedly provided at the inner circle of the left end of the basin, a heat dissipation hole being provided on the baffle, a metal base plate being vertically provided on the right side of the baffle, the metal base plate being annular in structure, the light strip being fitted on the inner wall of the metal base plate; the right end of the metal base plate is spaced apart from the first elastic metal ring, and the space is filled with sound-absorbing sponge, a heat dissipation cavity being enclosed between the basin, the baffle, the metal base plate, the sound-absorbing sponge and the first elastic metal ring.

[0006] Optionally, a mounting ring plate is provided at a distance from the left inner circle of the basin frame and on the right side of the second elastic metal ring, and an elastic member is connected between the first elastic metal ring, the second elastic metal ring and the mounting ring plate.

[0007] Optionally, the elastic member includes a bolt mounted on the mounting ring plate, the bolt passing through the second elastic metal ring and the first elastic metal ring, the left end of the bolt is connected to a nut, and a second spring and a first spring are respectively extruded on the bolt between the nut and the first elastic metal ring and between the second elastic metal ring and the mounting ring plate.

[0008] Optionally, a plurality of radially distributed waist-shaped holes are opened along the circumferential direction on the outer edge of the eardrum, and the bolts are arranged to pass through the waist-shaped holes.

[0009] Optionally, the left end of the outer wall of the metal substrate is connected to a plastic convex membrane that is convex upward and extends to the right, and a plastic concave membrane that is concave to the left is connected between the right end of the plastic convex membrane and the right part of the metal substrate. A vent hole is provided on the plastic concave membrane, and a plastic connecting part is connected between the plastic concave membrane and the first elastic metal ring.

[0010] Optionally, a controller is further included, and the wiring of the light strip is passed through the metal substrate, the plastic convex film and the basin frame in sequence and then electrically connected to the controller.

[0011] Optionally, a plurality of protrusions are provided on the right inner edge of the baffle, and the protrusions are spaced apart from the metal substrate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention secures the eardrum between a first elastic metal ring and a second elastic metal ring. A heat dissipation cavity is formed between the basin frame, baffle, metal base plate, sound-absorbing sponge, and the first elastic metal ring. When the volume is high or external interference vibrations are large, the outer edge of the eardrum can drive the first and second elastic metal rings to follow, thereby preventing the eardrum from exceeding its vibration range and being damaged. Furthermore, the vibration of the first and second elastic metal rings can change the size of the heat dissipation cavity, accelerating airflow exchange between the heat dissipation cavity and the outside world, thereby improving the heat dissipation effect of the heat dissipation cavity.

[0014] 2. The present invention provides a plastic convex film, a plastic concave film, and a plastic connecting portion on the outer wall of the metal substrate. The plastic convex film can prevent rainwater from reaching the metal substrate, thereby improving the waterproof effect of the metal substrate. When the first and second elastic metal rings vibrate rightward, the heat dissipation cavity space increases, posing an air intake state. The plastic concave film is pulled rightward, and the vent is in an air intake state. When the first and second elastic metal rings vibrate leftward, the heat dissipation cavity space decreases, posing an air outlet state. The plastic concave film is pushed leftward, and the vent is in an air outlet state. This effectively improves the heat dissipation effect of the metal substrate.

[0015] 3. The present invention provides an elastic member between the first elastic metal ring, the second elastic metal ring and the mounting ring plate, which can improve the stability of the first elastic metal ring and the second elastic metal ring, that is, reduce the vibration of the first elastic metal ring and the second elastic metal ring caused by the natural vibration of the eardrum, and at the same time, the elastic member can increase the clamping force of the first elastic metal ring and the second elastic metal ring on the outer edge of the eardrum.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: See Figure 1 and Figure 2The present invention provides a vocal amplifier with lights, comprising a mounting panel 1, a sound amplification port 101 being provided on the mounting panel 1, and a loudspeaker body 2 and a light strip 3 being installed on the right side of the sound amplification port 101. Among them, the loudspeaker body 2 includes a basin frame 201, and a tympanum 202 is provided on the left part of the basin frame 201. A first elastic metal ring 304 and a second elastic metal ring 305 are respectively provided at the inner circle of the left part of the basin frame 201 in the left and right directions. The tympanum 202 is fixedly clamped between the first elastic metal ring 304 and the second elastic metal ring 305. A baffle 301 is fixedly provided at the inner circle of the left end of the basin frame 201. The baffle 301 is provided with a heat dissipation hole 3011. A metal base plate 302 is vertically provided on the right side of the baffle 301. The metal base plate 302 is annular in structure. Several bosses 3012 are provided on the inner edge of the right side of the baffle 301. The bosses 3012 are spaced apart from the metal base plate 302. The spacing forms a light strip installation space. The light strip 3 is fitted on the inner wall of the metal base plate 302 and its position is limited by the bosses 3012. The right end of the metal base plate 302 is spaced apart from the first elastic metal ring 304, and this space is filled with a sound-absorbing sponge 303. A heat dissipation cavity is enclosed between the basin frame 201, the baffle 301, the metal base plate 302, the sound-absorbing sponge 303, and the first elastic metal ring 304. When the eardrum 202 vibrates with a large amplitude, the outer edge of the eardrum 202 can drive the first elastic metal ring 304 and the second elastic metal ring 305 to follow, thereby preventing the eardrum 202 from exceeding its vibration range and being damaged. At the same time, the vibration of the first elastic metal ring 304 and the second elastic metal ring 305 can cause the size of the heat dissipation cavity to change, accelerating airflow exchange between the heat dissipation cavity and the outside world, thereby improving the heat dissipation effect of the heat dissipation cavity. The left and right ends of the sound-absorbing sponge 303 are bonded to the right end of the metal base plate 302 and the left side wall of the first elastic metal ring 304, respectively. The sound-absorbing sponge 303 serves to stabilize the outer edge of the eardrum 202 and reduce the vibration of the first and second elastic metal rings 304, 305, caused by the natural vibration of the eardrum 202. This vibration compensates for excessive vibration of the eardrum 202, thereby minimizing damage to the eardrum 202. Furthermore, the sound-absorbing sponge 303 fills the gap between the metal base plate 302 and the first elastic metal ring 304, creating a relatively closed heat dissipation cavity. When the first elastic metal ring 304 vibrates, air exchange within the heat dissipation cavity occurs exclusively through the heat dissipation holes 3011. Finally, if the gap between the sound-absorbing sponge 303 is not filled, air flowing in and out of this narrow gap during eardrum 202 vibration will generate some acoustic noise, which in turn affects the sound amplification quality.

[0021] Based on the above embodiment, a mounting ring plate 203 is installed at a distance from the left inner circle of the basin frame 201, to the right of the second elastic metal ring 305. An elastic member 5 is connected between the first and second elastic metal rings 304, 305, and the mounting ring plate 203. The elastic member 5 comprises a bolt 501 mounted on the mounting ring plate 203. The bolt 501 passes through the second and first elastic metal rings 305, 304, respectively. A nut 504 is connected to the left end of the bolt 501. A second spring 503 and a first spring 502 are respectively squeezed onto the bolt 501 between the nut 504 and the first elastic metal ring 304 and between the second elastic metal ring 305 and the mounting ring plate 203. The provision of the second spring 503 and the first spring 502 improves the positional stability of the first and second elastic metal rings 304, 305, and enhances the grip of the first and second elastic metal rings 304, 305 on the outer edge of the eardrum 202. Furthermore, the outer edge of the eardrum 202 is provided with a plurality of radially distributed waist-shaped holes 2021 along the circumference, and the bolts 501 are inserted through the waist-shaped holes 2021. When the volume is very loud or the external interference vibration is very large, the outer edge of the eardrum 202 can slide and relax relative to the first elastic metal ring 304 and the second elastic metal ring 305 over a small distance. This sliding fit can be used to compensate for the vibration of the first elastic metal ring 304 and the second elastic metal ring 305, thereby reducing the risk of damage to the eardrum 202 due to excessive vibration.

[0022] Based on the above embodiment, the left end of the outer wall of the metal substrate 302 is connected with a plastic convex membrane 4 that is convex upward and extends to the right, and a plastic concave membrane 401 that is concave to the left is connected between the right end of the plastic convex membrane 4 and the right part of the metal substrate 302. A vent hole 402 is opened on the plastic concave membrane 401, and a plastic connecting part 403 is connected between the plastic concave membrane 401 and the first elastic metal ring 304. On the one hand, the plastic convex film 4 can prevent rain from reaching the metal substrate 302, thereby improving the waterproof effect of the metal substrate 302; on the other hand, when the first elastic metal ring 304 and the second elastic metal ring 305 vibrate to the right, the heat dissipation cavity space increases and is in an air intake state, the plastic concave film 401 is pulled to the right, the space enclosed by the plastic convex film 4 and the plastic concave film 401 increases, and the vent 402 is in an air intake state, so that the outside air can easily penetrate into the plastic concave film 401 and enter through the vent 402, and when the first elastic metal ring 304 and the second elastic metal ring 305 vibrate to the left, the heat dissipation cavity space decreases and is in an air outlet state, the plastic concave film 401 is pushed to the left, the space enclosed by the plastic convex film 4 and the plastic concave film 401 decreases, and the vent 402 is in an air outlet state, so that the hot air near the metal substrate 302 can be discharged to the outside from the vent 402 and the heat dissipation hole 3011 in turn, effectively improving the heat dissipation effect of the metal substrate 302.

[0023] Based on the above embodiment, the loudspeaker further includes a controller (not shown in the figure), which is mounted on the mounting panel 1. The wiring of the light strip 3 passes through the metal substrate 302, the plastic convex membrane 4 and the basin frame 201 in sequence, and is electrically connected to the controller together with the wiring of the loudspeaker body 2.

[0024] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
