Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of loudspeakers, in particular to a loudspeaker with a high-rigidity diaphragm body. Background Art
[0002] A loudspeaker, also known as a horn, is used to realize the conversion between electrical signals and sound signals. Its components usually include a magnetic circuit system including a base frame and settings, a diaphragm, a body, a voice coil and a spring. Among them, the diaphragm and the body are two key components of the loudspeaker. The diaphragm is the main component of the loudspeaker for sound generation. The vibration of the diaphragm generates sound waves, which are transmitted into the air through the opening of the loudspeaker and are heard by us. The body fixes the diaphragm to ensure that the diaphragm works stably in the correct position. At the same time, the body also serves as the back cavity for sound propagation, which has a certain influence on the propagation and reflection of sound.
[0003] In the prior art, since rigidity has a significant impact on the sound performance and service life of the speaker, increasing the rigidity of the diaphragm and the body is an important consideration in speaker design. Many speakers on the market now use metal diaphragms and bodies to enhance their rigidity. However, the cost of metal diaphragm bodies is usually high and may produce unnecessary resonance or metallic sound. Utility Model Content
[0004] In view of the above-mentioned deficiencies in the prior art, the present application provides a loudspeaker with a high-rigidity diaphragm body, aiming to reduce the cost while increasing the rigidity of the diaphragm body.
[0005] The above invention objectives of the present application are achieved through the following technical solutions:
[0006] A base frame is provided with a terminal board, and a magnetic circuit assembly, a spring, a voice coil, a carcass and a diaphragm are arranged in the base frame from bottom to top. The spring is sleeved on the voice coil, and the voice coil is electrically connected to the terminal board. The carcass is sleeved on the top of the voice coil, and the diaphragm is fixedly connected to the top of the carcass. A reinforcing rib is coaxially arranged inside the carcass near the diaphragm, and the end of the reinforcing rib abuts against the inner wall of the carcass, and the reinforcing rib is used to provide outward support force to the inner wall of the carcass.
[0007] By adopting the above technical scheme, under the action of the reinforcing ribs, the carcass is supported by the reinforcing ribs from the inside out, so that during the vibration of the diaphragm, the reinforcing ribs can effectively disperse and resist external forces, reduce the deformation of the carcass, and thus improve the rigidity of the carcass, and by arranging the reinforcing ribs at the junction of the diaphragm and the carcass, the stability and strength of the diaphragm carcass can be increased, thereby simultaneously improving the rigidity of the diaphragm, and then the effect of the mid-frequency band can be improved. Compared with traditional speakers that directly use a diaphragm carcass made of metal, it can reduce costs while improving the rigidity of the diaphragm and the carcass, and avoid generating additional metal sounds during vibration.

[0009] By adopting the above technical solution, setting flanges and connecting protruding rings, the diaphragm and the base frame can be provided with a connection position, and then through bonding, the connection between the diaphragm and the base frame can be made tighter and more stable, so as to reduce energy loss during the vibration process, thereby improving the sound transmission efficiency and fidelity.
[0010] In a preferred example, the present application can be further configured as follows: the connecting protruding ring is provided with a plurality of connecting holes.
[0011] By adopting the above technical solution and providing a connection hole, the speaker can be easily installed on an external device through the connection hole.

[0013] By adopting the above technical solution, a basin frame is set up to provide support and installation positions for various components of the speaker, and the U iron is set at the open end of the bottom of the basin frame, which can not only guide the magnetic field for the magnetic circuit assembly, but also support the basin frame.
[0014] In a preferred example, the present application can be further configured as follows: the magnetic circuit assembly includes a washer, a first magnet, and a second magnet bonded in sequence, and the washer is fixedly connected to the bottom of the voice coil by bonding.
[0015] By adopting the above technical solution and setting the first magnet and the second magnet, a stable magnetic field can be provided to the voice coil, so that the voice coil can move in the magnetic field under the action of the electric current, thereby driving the diaphragm to vibrate and produce sound. The washer can be responsible for connecting the magnet and the base frame to ensure the stability of the overall structure of the speaker, while reducing the magnetic resistance to ensure smooth passage of the magnetic field.
[0016] In a preferred example, the present application can be further configured as follows: the washer, the first magnet and the second magnet are all in the shape of a racetrack.
[0017] By adopting the above technical solution, the first magnet and the second magnet with a racetrack design can provide a more stable and uniform magnetic field, thereby optimizing the movement of the voice coil and further improving the sound quality and the overall performance of the speaker.
[0018] In a preferred example, the present application can be further configured as follows: a dust cap is provided on the top of the diaphragm.
[0019] By adopting the above technical solution and providing a dust cap, it is possible to prevent external dust particles from falling into the voice coil and affecting the normal operation of the voice coil and various components, thereby extending the service life of the speaker.
[0020] In a preferred example, the present application may be further configured as follows: the voice coil is electrically connected to the terminal board via a wire.
[0021] In summary, the present application includes at least one of the following beneficial technical effects:
[0022] 1.

By setting flanges and connecting convex rings, a connection position can be provided for the diaphragm and the base frame, and then by bonding, the connection between the diaphragm and the base frame can be made tighter and more stable, so as to reduce energy loss during the vibration process, thereby improving the sound transmission efficiency and fidelity.

The voice coil 5 can be powered by being electrically connected to an external device or a power supply through the terminal board 2, the body 6 is sleeved on the top of the voice coil 5, and the diaphragm 7 is fixedly connected to the top of the body 6 by means of bonding, and a reinforcing rib 9 is coaxially arranged at a position near the diaphragm 7 inside the body 6, and the end of the reinforcing rib 9 abuts against the inner wall of the body 6, and the reinforcing rib 9 is used to provide the inner wall of the body 6 with a direction Under the action of the reinforcing ribs 9, the body 6 is supported from the inside out by the reinforcing ribs 9, so that during the vibration of the diaphragm 7, the reinforcing ribs 9 can effectively disperse and resist the external force, reduce the deformation of the body 6, and thus improve the rigidity of the body 6, and by arranging the reinforcing ribs 9 at the junction of the diaphragm 7 and the body 6, the stability and strength of the diaphragm 7 and the body 6 can be increased, thereby simultaneously improving the rigidity of the diaphragm 7, and then the effect of the mid-frequency band can be improved. Compared with the traditional speaker that directly uses the diaphragm 7 and the body 6 made of metal material, it can reduce the cost while improving the rigidity of the diaphragm 7 and the body 6, and avoid generating additional metal sound during the vibration process.
[0033] It should be noted that the diaphragm 7, the body 6 and the reinforcing ribs 9 can all be made of light-weight and low-cost materials such as plastic and wood.
[0034] Furthermore, a flange 10 is extended outward from the edge of the diaphragm 7, and a connecting convex ring 13 is extended outward from the top of the base frame 1. The flange 10 and the connecting convex ring 13 are fixedly connected by bonding. By providing the flange 10 and the connecting convex ring 13, a connection position can be provided for the diaphragm 7 and the base frame 1, and then the connection between the diaphragm 7 and the base frame 1 can be made tighter and more stable by bonding, so as to reduce energy loss during the vibration process, thereby improving the sound transmission efficiency and fidelity.
[0035] Furthermore, the connection protruding ring 13 is provided with a plurality of connection holes 14 . By providing the connection holes 14 , it is convenient to install the speaker on an external device through the connection holes 14 .
