[0029] At present, the number of speakers installed in cars is increasing. In order to save the number of supply channels, tweeters generally adopt a design of adding capacitors for passive frequency division.

[0030] The existing capacitor components are placed on the back of the tweeter rear cover. The rear cover is designed with three retaining walls to limit the capacitor position. Generally, the capacitor is first placed in the limiting retaining wall, and then the contact part between the capacitor and the retaining wall is fixed with glue. However, before the capacitor is fixed with glue, it is easy to fall out from the side of the limiting retaining wall structure away from the rear cover of the speaker, which reduces the stability of the capacitor.

[0031] Figure 1 The schematic diagram shows the structure of the sound-generating device according to the embodiment of the utility model. Figure 2 The structure diagram of the sound-generating device according to the embodiment of the utility model from another perspective is schematically shown. Figure 1 and 2 As shown, the utility model proposes a sound-generating device and an electronic device. The sound-generating device in the utility model includes a speaker unit 10 and an electrical unit, the electrical unit includes an electronic device 21 and a limiter, the limiter includes a first limiter 221 and a second limiter 222 respectively connected to the outside of the speaker unit 10, the first limiter 221 and the second limiter 222 are arranged relatively spaced along the first direction, the first limiter 221, the second limiter 222 and the speaker unit 10 are enclosed to form a limiter groove, the electronic device 21 is arranged in the limiter groove along the second direction, the end of the first limiter 221 away from the speaker unit 10 is bent toward the second limiter 222 to press the side of the electronic device 21 away from the speaker unit 10, and the first direction and the second direction are arranged vertically.

[0032] According to the sound-emitting device of the utility model, the electrical unit is arranged on the speaker unit 10, and the first limiting portion 221 and the second limiting portion 222 of the limiting member can limit the electronic device 21 located in the limiting groove in a first direction, wherein one end of the first limiting member is bent toward the second limiting member, and can limit the side of the electronic device 21 away from the speaker unit 10. Compared with the existing limiting structure using three retaining walls, the first limiting portion 221 of the utility model is bent and set to limit the side of the electronic device 21 in the limiting groove away from the speaker unit 10, so that the electronic device 21 is not easy to fall out of the limiting groove, thereby improving the stability of the electronic device 21.

[0033] Specifically, in this embodiment, the electronic device 21 is a capacitor, the sound-generating device is a speaker, and the capacitor is arranged on the speaker, so that a passive frequency division design can be performed for the speaker.

[0034] In some embodiments of the present invention, Figure 1 and 2 As shown, the first limiting portion 221 includes a main body 2211 and a bending portion 2212 connected to each other, the main body 2211 and the second limiting portion 222 are arranged relatively along the first direction, the bending portion 2212 is arranged on the side of the electronic device 21 away from the speaker unit 10, and the main body 2211, the bending portion 2212, the second limiting portion 222 and the speaker unit 10 are surrounded to form a limiting groove. In this embodiment, the main body 2211 and the second limiting portion 222 are arranged relatively along the first direction, and the capacitor can be arranged between the second limiting portion 222 and the main body 2211, thereby achieving the first direction of the capacitor. The bending portion 2212 is connected to the main body 2211 and is located above the capacitor, and can limit the side of the capacitor away from the speaker unit 10 to prevent the capacitor in the limiting groove from escaping. Specifically, in this embodiment, the direction of the bending portion 2212 toward the speaker unit 10 is the third direction, and the bending portion 2212 can limit the capacitor in the third direction.

[0035] Specifically, in this embodiment, if Figure 1 and 2 As shown, the limiting groove is formed by the main body 2211, the bending portion 2212, the second limiting portion 222 and the speaker unit 10. The capacitor can be inserted into the limiting groove from the second direction, thereby achieving limitation and fixation of the capacitor in the first direction and the third direction.

[0036] Specifically, in this embodiment, at least one end of the main body along the second direction is provided with a locking portion 2213 facing the second limiting portion to abut against the electronic component of the limiting groove, which can limit the capacitor in the second direction, thereby further improving the stability of the capacitor.

[0037] In some embodiments of the present invention, Figure 1 and 2 As shown, the side of the bending portion 2212 facing the electronic device 21 is an arc-shaped surface, and the arc-shaped surface is arranged to fit the outer surface of the electronic device 21. In this embodiment, the capacitor is a cylindrical structure, and the inner surface of the bending portion 2212 is an arc-shaped surface, which can better fit the cylindrical capacitor, thereby achieving better positioning and fixing.

[0038] In some embodiments of the present invention, Figure 1 and 2 As shown, along the second direction, the length a of the bent portion 2212 is one third of the length of the electronic device 21. In this embodiment, the above arrangement enables the bent portion 2212 to be located above part of the limiting groove, thereby enabling the bent portion 2212 to be partially fitted with the capacitor of the limiting groove. When the operator plugs the capacitor, it can be plugged into the limiting groove not only along the second direction, but also from the third direction, making it easy for the operator to install the capacitor in multiple directions. At the same time, when the operator plugs into the limiting groove from the third direction, the capacitor can be inserted more conveniently, thereby improving convenience.

[0039] In some embodiments of the present invention, Figure 1 and 2 As shown, along the first direction, the length of the bending portion 2212 is half the length of the electronic device 21. In this embodiment, the above arrangement can ensure that there is a certain gap between the bending portion 2212 and the second limiting portion 222, so that the contact area between the bending portion 2212 and the capacitor of the limiting groove is further reduced, which can ensure that the capacitor can not only be resisted and limited in the third direction, but also can further improve the convenience of the operator when plugging into the limiting groove from the third direction.

[0040] In some embodiments of the present invention, Figure 1 and 2 As shown, the bending portion 2212 and the two end surfaces of the main body 2211 along the second direction are respectively aligned. In this embodiment, the above arrangement enables the bending portion 2212 to be connected to one side of the main body 2211 along the second direction, that is, the bending portion 2212 is arranged close to one side of the main body 2211 along the second direction. When the operator installs it to the limiting groove from the third direction, one end of the capacitor can be inserted below the bending portion 2212 first, and then the other end of the capacitor can be installed in the limiting groove, which enables the operator to conveniently install the capacitor to the limiting groove, thereby improving convenience.

[0041] In some embodiments of the present invention, Figure 1 and 2As shown, the second limiting portion 222 and the main body 2211 are both straight plate structures, and the bent portion 2212 is an arc plate structure. In this embodiment, since the capacitor is a cylindrical structure, the two straight plate structures in the first direction can abut the opposite ends of the capacitor, thereby achieving the first discovered limit. The arc plate structure can abut against an arc-shaped side of the capacitor away from the speaker unit 10 in the third direction, which can make the capacitor more compatible with the limiting groove, thereby improving the limiting ability and stability.

[0042] In some embodiments of the present invention, Figure 1 and 2 As shown, the second limiting portion 222 is a plug-in component. In this embodiment, the second limiting portion 222 can also be a plug-in component on the outside of the speaker unit 10, and there is no need to set up a limiting plate structure separately. The side wall of the component (plug-in component) on the outside of the speaker unit 10 can also cooperate with the first limiting portion 221 to realize the enclosure of the limiting groove.

[0043] In some embodiments of the present invention, Figure 2 As shown, the speaker unit 10 includes a speaker body 12 and a support frame 11, wherein a receiving cavity having an opening is defined in the support frame 11, the speaker body 12 is disposed in the receiving cavity, and the electrical unit is disposed on a side of the support frame 11 away from the opening. In this embodiment, the speaker body 12 is connected to the receiving cavity through the opening, and the first limiting portion 221 and the second limiting portion 222 are respectively connected to a side of the support frame 11 away from the opening along a third direction. The support frame 11 can not only accommodate the speaker, but also support and connect the electrical unit.

[0044] Furthermore, in this embodiment, a pin is provided at one end of the capacitor and welded to the support frame 11, and the other end of the capacitor is pressed by the bent portion 2212, which is not easy to fall out, and the gluing process is reduced.

[0045] The utility model also provides an electronic device having the above-mentioned sound generating device.

[0046] According to the sound-generating device of the electronic device of the utility model, the electrical unit is arranged on the speaker unit 10, and the first limiting portion 221 and the second limiting portion 222 of the limiting member can limit the electronic device 21 located in the limiting groove in the first direction, wherein one end of the first limiting member is bent toward the second limiting member, and can limit the electronic device 21 in the third direction. Compared with the existing limiting structure using three retaining walls, the first limiting portion 221 of the utility model that is bent can limit the electronic device 21 in the limiting groove in the third direction, so that the electronic device 21 is not easy to escape from the limiting groove, thereby improving the stability of the electronic device 21.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
