Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker basin frame integrated with hardware and plastics. Background Art

[0002] A loudspeaker, also known as a speaker, is used to realize the conversion between electrical signals and sound signals. Its components usually include a basin frame and settings including a diaphragm, voice coil, elastic wave, etc. Among them, the basin frame is the "skeleton" of the speaker. Its main function is to combine the diaphragm, voice coil, elastic wave and other components together to form a complete vibration system. At the same time, the basin frame can also play the role of installing the speaker on the sound box.

[0003] In the prior art, in order to save costs and improve production efficiency, most of the speakers on the market now use plastic basin frames made of injection molding. However, due to the low strength of the plastic basin frame, the thickness of the plastic basin frame needs to be 1.2-1.5mm, so that when the plastic basin frame is installed with a speaker of the same specification and thickness, the thickness of the speaker shell will be thinner, which is easy to cause the speaker to vibrate. In addition, the sealing EVA width at the connection between the speaker shell and the plastic basin frame is narrow, the sealing is poor, and air leakage is easy to occur, which needs to be solved urgently. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a loudspeaker basin frame integrating hardware and plastic.

[0005] The above invention objectives of the present application are achieved through the following technical solutions:

[0006] A mounting ring frame, wherein the mounting ring frame is hollow and made of plastic material;

[0007] A chassis, the chassis is installed in the mounting ring frame, a magnetic circuit assembly, a voice coil, a spring, a diaphragm and a dust cover are arranged in sequence from bottom to top inside the chassis, a terminal board is arranged at the bottom of the chassis, the voice coil is electrically connected to the terminal board, and the chassis is made of metal material;

[0008] A speaker shell, wherein a mounting groove for the base frame to pass through is opened on the top of the speaker shell, and when the base frame is located in the mounting groove, the base frame fits against the inner wall of the mounting groove, and the mounting ring frame is fixedly installed on the speaker shell at a port corresponding to the mounting groove, and an EVA gasket is arranged between the mounting ring frame and the speaker shell.

[0009] By adopting the above technical scheme, the base frame made of metal material is thinner than the traditional plastic material at the same strength, so that when the base frame is located in the installation groove and fits with the inner wall of the installation groove, the speaker shell can have a larger thickness design margin, thereby improving the speaker vibration phenomenon, and the greater the thickness of the speaker shell, the greater the width that the EVA gasket can be set to, so as to reduce the possibility of speaker leakage. In addition, by setting a mounting ring frame, the base frame can be provided with an installation position and the auxiliary base frame can be installed in the mounting groove. Since the mounting ring frame is installed outside the mounting groove, the mounting ring frame made of plastic material can have a larger width design margin at the same strength, so as to increase the contact area between the mounting ring frame and the EVA gasket, thereby further reducing the possibility of speaker leakage. At the same time, compared with the traditional single-material basin frame, the integrated combination of the mounting ring frame made of plastic material and the base frame made of metal material can also improve the heat dissipation effect and strength performance of the speaker.

[0010] In a preferred example, the present application can be further configured as follows: a card slot is provided on the inner side wall of the mounting ring frame along its circumference direction, and a card protrusion is extended from the outer side of the base frame, and the card protrusion is engaged with the card slot.

[0011] By adopting the above technical solution, the installation of the mounting ring frame and the base frame can be achieved under the clamping cooperation of the clamping groove and the clamping protrusion.

[0012] In a preferred example, the present application can be further configured as follows: a limiting flange is extended inside the mounting ring frame corresponding to the slot, and when the locking protrusion and the slot are engaged, the base frame abuts against the limiting flange.

[0013] By adopting the above technical solution, when the base frame is installed inside the mounting ring frame, the limiting flange can limit the base frame, making it easier for workers to install it.

[0014] In a preferred example, the present application can be further configured as follows: the EVA gasket is fixedly connected between the mounting ring frame and the speaker housing by bonding.

[0015] By adopting the above technical solution and the bonding method, the EVA gasket can adapt to surfaces of various shapes and sizes to achieve effective fixation and good sealing performance, which is suitable for speaker installation conditions.

[0016] In a preferred example, the present application can be further configured as follows: the base frame is provided with a plurality of material-saving holes.

[0017] By adopting the above technical solution, a number of material-saving holes are set to maximize the saving of metal materials while maintaining the strength and stability of the structure.

[0018] In a preferred example, the present application can be further configured as follows: the thickness of the base frame is 0.5 mm, and the thickness of the speaker shell is 1.65 mm.

[0019] In summary, the present application includes at least one of the following beneficial technical effects:

[0020] 1. The base frame made of metal material is thinner than that of traditional plastic material at the same strength, so that when the base frame is located in the installation groove and fits with the inner wall of the installation groove, the speaker shell can have a larger thickness design margin, thereby improving the speaker vibration phenomenon, and the greater the thickness of the speaker shell, the greater the width that the EVA gasket can be set to, so as to reduce the possibility of speaker leakage. By setting a mounting ring frame, the base frame can be provided with an installation position and the auxiliary base frame can be installed in the mounting groove. Since the mounting ring frame is installed outside the mounting groove, the mounting ring frame made of plastic material can have a larger width design margin at the same strength to increase the contact area between the mounting ring frame and the EVA gasket, thereby further reducing the possibility of speaker leakage.

[0021] 2. Compared with the traditional basin frame made of a single material, the integrated combination of the mounting ring frame made of plastic material and the base frame made of metal material can also improve the heat dissipation effect and strength performance of the speaker.

[0022] 3. By setting a number of material-saving holes, the metal material savings can be maximized while maintaining the strength and stability of the structure. BRIEF DESCRIPTION OF THE DRAWINGS

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally means that the associated objects before and after are in an "or" relationship.

[0031] The following describes a loudspeaker basin frame integrated with hardware and plastics of the present application with reference to the accompanying drawings.

[0032] like Figure 1 and Figure 2 As shown, the hardware-plastic integrated speaker basin frame includes a mounting ring frame 1, a base frame 2 and a speaker housing 3. The mounting ring frame 1 is hollow and made of plastic material. The base frame 2 is installed in the mounting ring frame 1 and is made of metal material. Specifically, a card slot 4 is opened on the inner side wall of the mounting ring frame 1 along its circumference direction. A card convex 5 is extended on the outer side of the base frame 2. The card convex 5 is engaged with the card slot 4. Under the card slot 4 and the card convex 5, the mounting ring frame 1 and the base frame 2 can be installed. In order to facilitate the installation of the staff, a limiting flange 6 is extended at the corresponding card slot 4 inside the mounting ring frame 1. When the card convex 5 and the card slot 4 are engaged, the base frame 2 abuts against the limiting flange 6. When the base frame 2 is installed inside the mounting ring frame 1, the limiting flange 6 can limit the base frame 2, which is convenient for the staff to install.

[0033] like Figure 3 and Figure 4As shown, the interior of the base frame 2 is provided with a magnetic circuit component 7, a voice coil 8, a spring 9, a diaphragm 10 and a dust cover 11 from bottom to top, a terminal board 12 is provided at the bottom of the base frame 2, the voice coil 8 is electrically connected to the terminal board 12, the magnetic circuit component 7 is used to provide a magnetic field to the voice coil 8, and by connecting the terminal board 12 to an external power supply, the voice coil 8 can be energized to drive the diaphragm 10 to vibrate, so that the speaker can make a sound, and a mounting groove for the base frame 2 to pass through is provided on the top of the speaker housing 3. When the base frame 2 is located in the mounting groove, the base frame 2 fits with the inner wall of the mounting groove, and the mounting ring frame 1 is fixedly installed at the corresponding mounting groove port of the speaker housing 3. An EVA gasket 13 is provided between the mounting ring frame 1 and the speaker housing 3 to fill the gap between the mounting ring frame 1 and the speaker housing 3. By adopting a base frame 2 made of metal material, compared with traditional plastic materials, the thickness is thinner at the same strength, so that when the base frame 2 is located When the speaker shell 3 is in the installation groove and fits with the inner wall of the installation groove, the speaker shell 3 can have a larger thickness design margin, so as to improve the speaker vibration phenomenon, and the greater the thickness of the speaker shell 3, the greater the width that the EVA gasket 13 can be set to, so as to reduce the possibility of speaker leakage. By setting the mounting ring frame 1, it is possible to provide a mounting position for the base frame 2 and assist the base frame 2 to be installed in the mounting groove. Moreover, since the mounting ring frame 1 is installed outside the mounting groove, the mounting ring frame 1 made of plastic material can have a larger width design margin at the same strength, so as to increase the contact area between the mounting ring frame 1 and the EVA gasket 13, so as to further reduce the possibility of speaker leakage. At the same time, compared with the traditional single-material basin frame, the integrated combination of the mounting ring frame 1 made of plastic material and the base frame 2 made of metal material can also improve the heat dissipation effect and strength performance of the speaker.

[0034] It should be noted that, through experiments, it is found that, when the overall thickness of the speaker is the same, within the range of 0.85mm-1.65mm, the greater the thickness of the speaker shell 3, the better the improvement effect of the speaker vibration phenomenon. In this embodiment, the thickness of the base frame 2 is 0.5mm, and the thickness of the speaker shell 3 is 1.65mm. The use of a base frame 2 and a speaker shell 3 of this size can not only ensure that the strength of the base frame 2 is qualified, but also improve the speaker vibration phenomenon, thereby improving the speaker sound quality.

[0035] Furthermore, the EVA gasket 13 is fixedly connected between the mounting ring frame 1 and the speaker housing 3 by bonding. By adopting the bonding method, the EVA gasket 13 can adapt to surfaces of various shapes and sizes to achieve effective fixation and good sealing performance, which is suitable for speaker installation conditions.

[0036] In addition, if Figure 1 As shown, the base frame 2 is provided with a plurality of material-saving holes 14 . By providing the plurality of material-saving holes 14 , the metal material saving is maximized while maintaining the strength and stability of the structure.

[0037] The above specific implementations do not constitute a limitation on the protection scope of this application. It should be understood by those skilled in the art that various modifications, combinations, sub-combinations and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included in the protection scope of this application.
