Description

Technical Field

[0001] This utility model relates to the field of loudspeaker technology, and in particular to a simple tweeter. Background Technology

[0002] Car audio is an indispensable part of the automotive industry, with speakers being a crucial component of the audio system. As car designs become more functional and numerous components increase, the already limited space for speaker placement is further compressed, especially for tweeters. The addition of capacitors necessitates soldering for the capacitor leads, coil leads, and the speaker's positive and negative terminals, and the coil leads are very thin and easily broken. Due to space constraints, many tweeter connectors can only be designed and placed at the rear, resulting in complex structures, a large number of downstream components, numerous manufacturing processes, low production efficiency, and high costs. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a simplified tweeter to simplify the structure, reduce lower-level components and manufacturing processes, improve production efficiency, and lower production costs.

[0004] To achieve the above objectives, the present invention provides a simplified tweeter comprising a vibrating plate, a vibrating plate assembly, and an outer casing. The vibrating plate is fitted with a capacitor and a positive electrode solder pad on its upper side. A U-shaped iron, a magnet, a sound post, and the vibrating plate assembly are sequentially mounted on the lower side of the vibrating plate from top to bottom. The vibrating plate assembly includes a voice coil and a diaphragm. The magnet and the sound post are located inside the voice coil, and the diaphragm is below the sound post. The vibrating plate is mounted on the outer casing, with the U-shaped iron, magnet, sound post, and vibrating plate assembly positioned between the vibrating plate and the outer casing. The invention is characterized by further including a connector mounted on the upper side of the vibrating plate. The connector has a positive electrode solder pad and a negative electrode solder pad. The two voice coil leads are soldered to the positive electrode solder pad and the negative electrode solder pad, respectively. The two leads of the capacitor are soldered to the positive electrode solder pad and the positive electrode solder pad, respectively.

[0005] The simplified tweeter provided by this utility model has only one positive electrode solder pad on the vibrating plate, eliminating the need for a negative electrode solder pad. This not only reduces the amount of injection molding particles and lower-level components of the tweeter, simplifying the tweeter structure, but also shortens the total injection molding time and reduces costs. The voice coil lead wire is directly soldered to the negative electrode solder pad of the connector, reducing the number of soldering steps. This not only saves on the cost of solder wire but also reduces the number of soldering operations, optimizing the production process and improving production efficiency. Attached Figure Description

[0010] The present invention will now be described in further detail with reference to the accompanying drawings. Detailed Implementation

[0011] See Figure 1 and Figure 2 The simplified tweeter includes a capacitor 1, a connector 2, a diaphragm assembly 3, a U-shaped iron 32, a magnet 4, a sound post 5, a diaphragm assembly 6, and an outer casing 7. The diaphragm assembly 3 is an injection-molded part with inserts. Its upper side has a positive electrode solder pad 31, a slot 33, and two sliding grooves 34. The slot 33 and two sliding grooves 34 are located at the top of the diaphragm assembly 3. The capacitor 1 is installed in the slot 33. The positive electrode solder pad 31 is located near the edge of the diaphragm assembly 3 and is used for soldering to one pin of the capacitor 1 and one lead 62 of the voice coil 61. The connector 2 is also an injection-molded part with inserts. It has a positive electrode solder pad 21 and a negative electrode solder pad 23, which are used for electrical connection to power signal lines. The connector 2 has a downwardly extending arm 22, with the negative electrode solder pad 23 located at the lower end of the arm 22. The connector 2 also has two parallel sliding blocks 24, which can mate with the grooves 34 on the vibrating plate firmware 3. The sliding blocks 24 of the connector 2 are inserted into the grooves 34, and the connector 2 is installed onto the vibrating plate firmware 3 through the engagement of the sliding blocks 24 and the grooves 34. The connector 2 and the vibrating plate firmware 3 are connected by a plug-in type, making installation and disassembly very convenient. The two leads of the capacitor 1 are soldered to the positive electrode solder pad 31 and the positive electrode solder pad 21, respectively. The positive electrode solder pads 31 and 21 are located on the lead side of the capacitor and close to the capacitor, which not only ensures a secure soldering between the capacitor leads and the positive electrode solder pads 31 and 21, but also facilitates the soldering operation and improves production efficiency.

[0012] The U-shaped iron 32, magnet 4, voice column 5, and diaphragm assembly 6 are sequentially mounted on the diaphragm fixture 3 from top to bottom, and are located in the lower center of the diaphragm fixture 3. Magnet 4 provides the magnetic field, and the U-shaped iron 32, magnet 4, and voice column 5 together form a magnetic circuit. The diaphragm assembly 6 includes a voice coil 61 and a diaphragm 63. Magnet 4 and voice column 5 are located inside the voice coil 61, and the diaphragm 63 is located below the voice column 5. The two voice coil leads 62 of the voice coil 61 are soldered to the positive electrode solder 31 and the negative electrode solder 23, respectively. The extension arm 22 of connector 2 extends downwards to a position close to the voice coil 61, minimizing the distance between the voice coil leads 62 and the negative electrode solder 23, avoiding breakage of the voice coil leads 62 due to excessive extension distance and entanglement, and ensuring a secure soldering between the voice coil leads 62 and the negative electrode solder 23. When the voice coil lead 62 is energized, the voice coil 61 experiences a force within the magnetic field, causing it to move and thus driving the diaphragm 63 to vibrate. (See also...) Figure 1 and Figure 3 The diaphragm fastener 3 is mounted on the outer cover 7, and inside the outer cover 7, the U-shaped iron 32, the magnet 4, the sound column 5, and the diaphragm assembly 6 are located between the diaphragm fastener 3 and the outer cover 7. The outer cover 7 serves to protect the diaphragm and other internal components.

[0013] Only one positive electrode solder pad (31) is set on the vibratory plate firmware 3; no negative electrode solder pad is required. During assembly, first press connector 2... Figure 4 The connector 23a is assembled with the vibratory plate fastener 3, and the negative electrode solder piece 23 of the connector 2 simultaneously becomes the negative electrode solder piece of the vibratory plate fastener 3. Then, the vibratory plate assembly 6 is assembled... Figure 4 The middle component 63a is assembled with the previous two components. A voice coil lead 62 is then soldered to the negative electrode solder pad 23. This voice coil lead 62 crosses the diaphragm fixture 3 and is directly soldered to the negative electrode solder pad 23 of the connector, ensuring a secure and easy soldering operation. Finally, the outer cover 7 is installed, the capacitor 1 is installed into the slot 33, and the two leads of the capacitor 1 are soldered to the positive electrode solder pad 31 and the positive electrode solder pad 21, respectively, completing the assembly.

[0014] This utility model is a simplified tweeter. The vibrating plate has only one positive electrode solder pad, eliminating the need for a negative electrode solder pad. This not only reduces the amount of injection molding particles and lower-level components of the tweeter, simplifying the tweeter structure, but also shortens the total injection molding time and reduces costs. The voice coil lead wire is directly soldered to the negative electrode solder pad of the connector, reducing the number of soldering steps. This not only saves on the cost of solder wire but also reduces the number of soldering operations, optimizing the production process and improving production efficiency.
