Description

Technical Field

[0001] This patent relates to the field of electroacoustic equipment technology, specifically to a multifunctional spring wave and loudspeaker. Background Technology

[0002] A loudspeaker, also known as a horn, is a commonly used electroacoustic transducer in electronic devices. A loudspeaker consists of a frame, diaphragm, voice coil, magnet, wire, spider, and U-shaped iron. The U-shaped iron and frame are the mounting components of the loudspeaker, while the diaphragm, voice coil, magnet, wire, and spider are mounted on the mounting structure formed by the U-shaped iron and frame. The voice coil and magnet are the power components of the loudspeaker. The magnetism of the energized coil in the voice coil interacts with the magnetism of the magnet to drive the diaphragm to vibrate, thus producing sound. The spider connects the voice coil and the frame to improve the stability of the voice coil's vibration, thereby improving the stability of the diaphragm's vibration and optimizing the sound quality of the loudspeaker. The coil in the voice coil is powered by the wire, which energizes the coil and generates magnetism. Therefore, the wire and spider are indispensable components in modern loudspeakers. The separate installation of the nylon wire and spider during loudspeaker production and assembly increases the complexity of loudspeaker production and assembly, making it inconvenient for loudspeaker production and assembly; moreover, the nylon wire is prone to snagging, which also affects the performance of the loudspeaker; at the same time, the nylon wire and spider components occupy a large space in the loudspeaker, which is not conducive to the miniaturization and thinning of the loudspeaker, and cannot meet market demands.

[0019] See Figure 1A multifunctional spring wave integrates the functions of a spring wave, nylon thread, and terminal. It includes an elastic connecting part 11, a paper drum mounting part 12, a bracket mounting part 13, and an external connecting part 15. These components are integrally formed as a metal structure using stamping or other molding methods. The paper drum mounting part 12 is used for mounting and fixing to the paper drum. It is a planar structure, allowing for adhesive bonding. The bracket mounting part 13 is used for mounting to a bracket. It can be a straight strip structure, allowing for insertion into the bracket or installation inside the bracket during injection molding of a plastic bracket. The paper drum mounting part 12 and the bracket mounting part 13 are located at opposite ends of the elastic connecting part 11, which provides elasticity to the spring wave. The elastic connecting part 11 is a wave-shaped sheet structure, integrally formed during the multifunctional spring wave molding process using stamping or other molding methods. The external connector 15 is disposed at the end of the bracket mounting portion 13 and is used for connection with an external circuit. The external connector 15 can be configured as a sheet, with the external wires soldered to the surface of the sheet-like external connector 15 when connected to the multi-functional spring wave; the external connector 15 can also be configured with a locking screw on the sheet-like structure, whereby the external wires are pressed and fixed to the external connector 15 by the locking screw when connected to the multi-functional spring wave; this embodiment discloses a structure in which the external connector 15 is configured as a sheet, with the external wires soldered to the surface of the sheet-like external connector 15 when connected to the multi-functional spring wave.

[0020] See Figure 1 In this embodiment, the multifunctional spider integrates the functions of a traditional spider, nylon wire, and terminals. The elastic connection part 11, the diaphragm mounting part 12, the bracket mounting part 13, and the external connection part 15 adopt an integrated metal structure, which is conductive to power the speaker voice coil and realize the conductive function of the nylon wire. At the same time, the multifunctional spider is provided with a wave-shaped elastic connection part 11 to realize the elastic function of the multifunctional spider, which can ensure the stability of the voice coil vibration, thereby improving the stability of the diaphragm vibration and thus optimizing the sound quality of the speaker. In addition, the multifunctional spider is provided with an external connection part 15 to connect to an external circuit, thereby powering the speaker voice coil. In summary, the multifunctional spider in this embodiment integrates the functions of a traditional spider, nylon wire, and terminal into one unit. When used in a loudspeaker, only one component is needed to achieve the functions of a traditional spider, nylon wire, and terminal. This simplifies the loudspeaker's structure, facilitates its production and assembly, improves its stability, and avoids the problem of nylon wire easily snagging in loudspeakers. At the same time, the multifunctional spider is smaller than the three components of a traditional spider, nylon wire, and terminal, which is beneficial for the miniaturization and thinning of loudspeakers, better meeting market demands.

[0021] See Figure 1In this embodiment, the multifunctional spider also includes a coil lead connection portion 14, which is disposed between the elastic connection portion 11 and the diaphragm mounting portion 12 for electrical connection with the lead wire of the speaker coil. The elastic connection portion 11, the diaphragm mounting portion 12, the bracket mounting portion 13, and the coil lead connection portion 14 are integrally formed metal structural components. The coil lead connection portion 14 is preferably designed as a planar structure to facilitate wire bonding. Simultaneously, reinforcing ribs can be provided on the coil lead connection portion 14 to ensure its strength.

[0022] See Figure 1 The elastic connecting part 11, the diaphragm mounting part 12, the bracket mounting part 13, and the coil lead connecting part 14 are preferably arranged in a zigzag shape. The elastic connecting part 11 is located in the middle of the zigzag structure, that is, in the middle of the diaphragm mounting part 12 and the bracket mounting part 13. This allows the elastic connecting part 11 sufficient space for elastic deformation, so that when the multi-functional spider is installed in the speaker, it can vibrate freely with the diaphragm, ensuring the sound quality of the speaker. The coil lead connecting part 14 is arranged perpendicular to the diaphragm mounting part 12, which facilitates the welding of the coil lead 43 to the coil lead connecting part 14.

[0023] See Figures 1-7 This embodiment provides a loudspeaker utilizing the aforementioned multifunctional spider. The loudspeaker includes a U-shaped iron 2, a magnetic component 3, a voice coil 4, a multifunctional spider 1, a bracket 5, and a diaphragm 6. The multifunctional spider 1 is the aforementioned multifunctional spider. Both the U-shaped iron 2 and the diaphragm 6 are mounted on the bracket 5. The U-shaped iron 2 and the bracket 5 form the mounting structure for the other components of the loudspeaker, while the diaphragm 6 is the sound-producing component of the loudspeaker. The magnetic component 3 and the voice coil 4 are disposed within the U-shaped iron 2. The magnetic component 3 is fixedly installed inside the U-shaped iron 2, while the voice coil 4 is freely movable between the inner wall of the U-shaped iron 2 and the magnetic component 3. The magnetism generated by the energized coil 42 on the voice coil 4 interacts with the magnetism of the magnetic component 3 to drive the diaphragm 6 to vibrate and produce sound. The diaphragm mounting part 12 is fixed to the middle of the diaphragm 6, and the bracket mounting part 13 is fixed to the bracket 5. Thus, when the diaphragm 6 vibrates and produces sound, the multifunctional spider provides limiting and guiding, ensuring stable vibration and sound production of the diaphragm 6, and guaranteeing the sound quality of the loudspeaker. The multifunctional spider can vibrate freely with the diaphragm, ensuring the sound quality of the loudspeaker.

[0024] See Figure 7The voice coil 4 includes a support body 41 and a coil 42. The support body 41 is bonded and fixed to the diaphragm 6, and the coil 42 is wound around the support body 41. The lead 43 of the coil 42 is electrically connected to the coil lead connection part 14 of the multifunctional spider 1. Thus, when the coil 42 of the voice coil 4 is powered on by the multifunctional spider 1, it can generate magnetism and interact with the magnetism of the magnetic component 3, causing the voice coil 4 to vibrate within the U-shaped iron 2. The diaphragm 6 bonded to the support body 4 vibrates with the voice coil 4 and produces sound.

[0025] See Figures 1-7 The speaker in this embodiment includes the aforementioned multifunctional spider, which integrates the functions of a traditional spider, nylon wire, and terminals. While achieving the conductivity of a traditional nylon wire, it also provides the elasticity of a multifunctional spider, ensuring the stability of the voice coil vibration and thus improving the stability of the diaphragm vibration, thereby optimizing the sound quality of the speaker. Furthermore, it can be connected to an external circuit via the external connector 15 to power the speaker's voice coil. In addition, the speaker in this embodiment uses the aforementioned multifunctional spider, which integrates the functions of a traditional spider, nylon wire, and terminals. During speaker assembly, only one component is needed to achieve the functions of a traditional spider, nylon wire, and terminals, simplifying the speaker's structure, facilitating production and assembly, improving the stability of the speaker, and avoiding the problem of nylon wire easily splaying in traditional speakers. Simultaneously, the multifunctional spider component is smaller than the three components of a traditional spider, nylon wire, and terminals, which is beneficial for speaker miniaturization and thinning, better meeting market demands.

[0026] See Figure 3 Preferably, the bracket 5 is made of injection-molded plastic, and the bracket mounting part 13 is injection-molded onto the bracket 5. Using injection-molded plastic allows the multi-functional spider 1 to be injection-molded onto the bracket 5 during injection molding, facilitating the production and assembly of the speaker; moreover, the plastic part does not affect the magnetic and electrical properties of other components of the speaker; and the plastic part is low in cost and light in weight, which can reduce the cost and weight of the speaker.

[0027] See Figure 2 and 6 In this embodiment, the drum mounting part 12 is glued and fixed to the drum 6. The glued method is convenient to operate, has high production efficiency, facilitates the installation of the multi-functional spider 1 and the drum 6, and can reduce the production and assembly cost of the speaker. The lead wire 43 of the coil 42 is soldered to the coil lead wire connection part 14 of the multi-functional spider 1. The soldering method is convenient and quick, has high production efficiency, and can reduce the production and assembly cost of the speaker.

[0028] See Figure 2 and 5The magnetic component 3 includes a first magnet 31, a washer 32, and a second magnet 33, which are fixedly disposed on opposite sides of the washer 32. The magnetic component 3, formed by two magnets and a washer, ensures that the magnetic component has sufficient magnetism to generate a mutual magnetic force with the voice coil 4.

[0029] See Figure 2 and Figure 7 The drum 6 includes a body 61 and a suspension edge 62. The suspension edge 62 is disposed on the outside of the body 61 and the outside of the suspension edge 62 is bonded and fixed to the bracket 5. The voice coil 4 drives the body 61 to vibrate and produce sound on the inside of the suspension edge 62.

[0030] See Figures 1-7 The speaker can be equipped with a set of multi-functional spider 1, U-shaped iron 2, magnetic component 3, voice coil 4, bracket 5, and diaphragm 6. A set of multi-functional spider 1 includes two components, which are preferably positioned on opposite sides of the diaphragm 6 to improve the stability of the diaphragm 6's vibration and optimize the speaker's sound quality. For example... Figure 7 In this embodiment, two sets of U-iron 2, magnetic component 3, voice coil 4 and multi-functional spider 1 are provided, and one set of bracket 5 and drum paper 6 are provided. The bracket 5 and drum paper 6 are long strip structures. The support body 41 of the two sets of voice coil 4 is fixed on the drum paper 6 along the length direction. The two sets of multi-functional spider 1 are fixed on opposite sides of the bracket 5. The lead wire of each set of voice coil 4 is electrically connected to one set of multi-functional spider 1. Thus, the two sets of voice coil 4 drive the two sides of the drum paper 6 to vibrate synchronously, so that the vibration balance and stability of the drum paper 6 are better, which can optimize the sound quality of the speaker.
