Description
Technical Field
[0001] This utility model relates to the field of automotive speaker technology, and in particular to an automotive speaker with an echo structure. Background Technology
[0002] Car speakers are devices used to emit sound signals and play music in a car. They convert electrical signals into sound, fulfilling an indispensable function of an audio system. The technical requirements for car speakers are higher than those for home audio systems because the complex environment inside a car, such as confined spaces, irregular objects, noise, and vibration, can all affect their performance.
[0003] A loudspeaker's structure generally includes a frame, cone, magnetic circuit, and voice coil. The frame is mainly used to install and support the components inside the loudspeaker. The frame includes an outer ring for fixing the cone, an inner ring for fixing the magnetic circuit, and connecting ribs between the inner and outer rings. Most existing loudspeakers produce sound by the vibration of the cone, but the vibration of the paper cone is directly transmitted through the air and dissipated, which degrades sound quality. Therefore, we propose a car loudspeaker with an echo structure to solve these problems. Utility Model Content
[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a car speaker with an echo structure.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a car speaker with an echo structure is designed, including a housing, a frame is installed at one end of the housing, a through hole is opened on the outer wall of the frame, a supporting skirt is installed along the edge of the frame away from the housing, and a first paper cone is provided inside the frame, with the edge of the first paper cone corresponding to the supporting skirt.
[0006] A second paper tray is provided on the side of the first paper tray away from the chassis. The middle of the second paper tray is separated from the middle of the first paper tray, and the edge of the second paper tray corresponds to the support skirt.
[0007] A support plate is provided at the end of the chassis away from the support skirt. The support plate has a slot corresponding to the chassis, so that the support plate can be fitted onto the chassis and fixed. A wide mask is installed along the edge of the support plate. The wide mask corresponds to the frame. Multiple spaced receiving slots are provided on the side of the wide mask, and an elastic echo membrane is installed in the receiving slot.
[0008] Preferably, a first annular plate is installed at the edge of the mask furthest from the support plate, and a second annular plate is installed vertically along the edge of the first annular plate. The inner wall of the second annular plate is fitted with the outer wall of the support skirt with a clearance. An annular cover plate is provided inside the second annular plate. The frontal projection of the cover plate is located on the side of the second paper basin furthest from the first annular plate, and the cover plate is connected to the second annular plate through a fixing ear.
[0009] Preferably, sealing rings are installed on the side of the cover plate that is relatively close to the first annular plate.
[0010] Preferably, a fixing frame is installed on the side of the slot away from the mask, and the fixing frame is fixed to the chassis by fasteners.
[0011] Preferably, a sealing gasket is installed on the inner wall of the fixed frame.
[0012] Preferably, a T-shaped iron is provided inside the chassis, the T-shaped iron is fixed to the inner wall of the chassis, and a magnet, a wattage, and a spider are fitted on the T-shaped iron.

[0013] Preferably, a fixing buckle is provided in the middle of the first paper cone, and the fixing buckle is threaded to the voice coil.
[0014] The design scheme proposed in this utility model has the following beneficial effects in application:
[0015] This car speaker with an echo structure uses a second cone positioned outside the first cone and an echo diaphragm positioned along the outside of the frame to reflect sound waves transmitted outward from the first cone, producing an echo effect that makes the sound richer and more three-dimensional, thereby improving the sound quality of the car speaker. By placing the echo diaphragm and the second cone on either side of the first cone, this car speaker effectively blocks sound waves propagating to both sides of the first cone when it vibrates, thus enhancing the source of the echo effect and ensuring sufficient echo generation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-4 A car speaker with an echo structure includes a housing 1, a frame 2 installed at one end of the housing 1, a through hole 3 on the outer wall of the frame 2, and a supporting skirt 4 installed along the edge of the frame 2 away from the housing 1.
[0023] Inside the chassis 1, there is a T-shaped iron 5, which is fixed to the inner wall of the chassis 1. A magnet 6, a wattage 7, and a spider 8 are fitted on the T-shaped iron 5. A voice coil 20 is connected to the end of the T-shaped iron 5. The end of the voice coil 20 extends into the frame 2, forming the power supply mechanism of the speaker. When powered on, the voice coil 20 will vibrate due to the attraction and repulsion of the magnet 6.
[0024] A first paper cone 9 is provided inside the frame 2. The edge of the first paper cone 9 corresponds to the supporting skirt 4. A fixing buckle is provided in the middle of the first paper cone 9. The fixing buckle is threaded to the voice coil 20. So when the voice coil 20 vibrates, it will drive the first paper cone 9 to vibrate, thereby radiating sound waves and forming sound.
[0025] A support plate 12 is provided at the end of the chassis 1 away from the support skirt 4. The support plate 12 has a slot 13 corresponding to the chassis 1, so that the support plate 12 is fitted onto the chassis 1 and fixed. That is, a fixing frame is installed on the side of the slot 13 away from the wide face mask 11. The fixing frame is fixed to the chassis 1 by fasteners. In actual use, the fasteners are one of bolts and screws, so that the fixing frame can be detachably installed on the chassis 1. The wide face mask 11 is installed along the edge of the support plate 12. The wide face mask 11 corresponds to the diaphragm 2. Multiple spaced receiving slots 14 are provided on the side of the wide face mask 11, and an elastic echo diaphragm 15 is installed in the receiving slot 14. When the first diaphragm 9 vibrates, the sound waves propagating from the first diaphragm 9 toward the through hole 3 will come into contact with the echo diaphragm 15, so that the sound waves in that direction can be reflected, thereby producing an echo.
[0026] A second diaphragm 10 is provided on the side of the first diaphragm 9 away from the chassis 1. The middle of the second diaphragm 10 is spaced from the middle of the first diaphragm 9, and the edge of the second diaphragm 10 corresponds to the support skirt 4. When the first diaphragm 9 vibrates, it can reflect the sound waves propagating from the first diaphragm 9 toward the second diaphragm 10. In conjunction with the echo diaphragm 15, it can reflect the sound waves propagating on both sides of the first diaphragm 9, thereby ensuring sufficient echo effect and improving the sound quality of the speaker.
[0027] It should be noted that a first annular plate 16 is installed at the edge of the mask 11 away from the support plate 12, and a second annular plate 17 is installed vertically along the edge of the first annular plate 16. The inner wall of the second annular plate 17 is fitted with the outer wall of the support skirt 4 with a clearance. An annular cover plate 19 is provided inside the second annular plate 17. The frontal projection of the cover plate 19 is located on the side of the second paper basin 10 away from the first annular plate 16. The cover plate 19 is connected to the second annular plate 17 through a fixing ear 18, which clamps and secures the first paper basin 9 and the second paper basin 10, and also facilitates the disassembly and assembly of the two paper basins.
[0028] Furthermore, sealing rings are installed on the side of the cover plate 19 that is relatively close to the first annular plate 16, which strengthens the stability of the paper cone when it is fixed and ensures the stability of the sound wave generation process.
[0029] Furthermore, to prevent sound waves from leaking out from the gaps in the installation locations and causing sound distortion, sealing gaskets are installed on the inner wall of the fixed frame.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
