Description

Technical Field

[0001] The utility model relates to the technical field of loudspeakers, in particular to an ultra-thin loudspeaker with a novel elastic wave structure. Background Art

[0002] Loudspeakers, also known as horns, are used to achieve the conversion between electrical signals and sound signals. Their components usually include a magnetic circuit system including a chassis and settings, a diaphragm, a body, a voice coil and a spring. Among them, the spring, also known as a centering support, is an important part of the speaker system. It supports, fixes and adjusts the movement of the voice coil, thereby ensuring that the speaker can produce clear and accurate sound.

[0003] In the prior art, the traditional speaker spring is usually set outside the voice coil to ensure the stable movement and accurate positioning of the voice coil, but this method will make the speaker larger and not light and compact enough. Under the current situation where the space utilization of speakers is increasingly required, it is necessary to make the speaker smaller and thinner to improve the space utilization while ensuring that the speaker has a good bass effect. Therefore, a thin speaker with good bass effect is needed. Utility Model Content

[0007] By adopting the above technical solution, a washer and a carcass are provided, which can respectively play a role of fixing and supporting the two ends inside the voice coil, so that the voice coil can be stably installed in the basin frame. At the same time, by arranging the washer on the elastic wave, the space utilization rate can be improved. When the voice coil is energized to drive the diaphragm and the carcass to vibrate, since the elastic wave is coaxially fixedly connected between the carcass and the magnet, and the voice coil is coaxially sleeved on the outside of the carcass, the elastic wave can simultaneously play a role of centering, supporting and fixing the carcass and the voice coil, and the elastic wave can control the vibration of the voice coil by controlling the vibration of the carcass inside the voice coil, so as to ensure that the elastic wave can effectively play a role of vibration control. Compared with traditional speakers, the elastic wave is arranged inside the voice coil and effectively plays a role of vibration control, which can improve the space utilization rate of the speaker and ensure that the speaker has a good bass effect.

[0009] By adopting the above technical solution and setting the first boss and the second boss, a position for connecting the spring wave with the carcass can be provided, and the effect of controlling the vibration of the spring wave can be improved under the effect of the arc transition.

[0010] In a preferred example, the present application can be further configured as follows: the elastic wave is provided with an arc-shaped convex ring along its circumference direction.

[0011] By adopting the above technical solution, an arc-shaped convex ring is provided to improve the effect of elastic wave vibration control.

[0012] In a preferred example, the present application can be further configured as follows: an installation groove is opened in the middle of the U-iron, a cavity for installing various components is formed between the installation groove and the basin frame, and the bottom surface of the U-iron is flush with the bottom of the basin frame.

[0013] By adopting the above technical solution, an installation groove is provided so that when the U iron is installed inside the basin frame, it forms a cavity for installing various components together with the basin frame, thereby improving the utilization rate of the speaker space.

[0014] In a preferred example, the present application can be further configured as follows: a plurality of positioning grooves are provided on the top of the U-iron, a plurality of positioning flanges are radially extended inside the basin frame corresponding to the positioning grooves, and the positioning grooves are plugged into and matched with the positioning flanges.

[0015] By adopting the above technical solution, the stability of the U-iron installation can be improved under the effect of the plug-in cooperation between the positioning groove and the positioning flange.

[0016] In a preferred example, the present application can be further configured as follows: a terminal board is provided on the outside of the basin frame, the voice coil is electrically connected to the terminal board through a wire, and the terminal board is electrically connected to an external power supply.

[0017] In summary, the present application includes at least one of the following beneficial technical effects:

[0018] 1. When the voice coil is energized to drive the diaphragm and the body to vibrate, since the elastic wave is coaxially fixedly connected between the body and the magnet, and the voice coil is coaxially sleeved on the outside of the body, the elastic wave can simultaneously play the role of centering, supporting and fixing the body and the voice coil, and the elastic wave can control the vibration of the voice coil by controlling the vibration of the body inside the voice coil, so as to ensure that the elastic wave can effectively play the role of vibration control. Compared with traditional speakers, the elastic wave is arranged inside the voice coil and effectively plays the role of vibration control, realizing the ultra-thin structural design of the speaker, so as to improve the space utilization of the speaker, and at the same time improve the power and sensitivity of the speaker, and ensure the good bass effect of the speaker.

[0019] 2. The special design of washer set on the spring wave can improve the space utilization.

[0020] 3. By opening the installation groove, when the U iron is installed inside the basin frame, it forms a cavity for installing various components together with the basin frame, thereby improving the utilization rate of the speaker space, improving the heat dissipation function of the speaker and reducing the risk of short circuit of the speaker wire.
