Abstract

The embodiments of the present invention provide a speaker mounting structure and an electronic device, and relate to the technical field of electronic product structures. The speaker mounting structure provided by the embodiments of the present invention includes a housing, at least one first elastic block and at least one second elastic block. The housing has a first inner wall, a second inner wall and a receiving cavity defined between the first inner wall and the second inner wall. The first elastic block and the second elastic block are both arranged in the receiving cavity, and the first elastic block is connected to the first inner wall, and the second elastic block is connected to the second inner wall. The first elastic block and the second elastic block cooperate with each other to limit the speaker to be clamped in the receiving cavity. The speaker mounting structure not only utilizes the elastic action of the elastic block to achieve effective vibration isolation, but also does not need to provide an inner concave notch on the speaker that greatly occupies the volume of the speaker, which helps to ensure the bass effect of the speaker.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0049] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0050] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0051] Figure 1 The exploded structure diagram of the speaker installation structure 100 provided in this embodiment is as follows: Figure 2 This is a schematic diagram of the internal structure of the speaker installation structure 100 provided in this embodiment. Figure 1 and Figure 2 , this embodiment provides a speaker installation structure 100, and accordingly, provides an electronic device.

[0052] The electronic device includes a speaker installation structure 100, and the electronic device also includes a speaker 200. The speaker 200 is locked and limited in the accommodating cavity 113 by the cooperation of the first elastic block 120 and the second elastic block 130. At the same time, the electronic device also includes other electronic devices (not shown in the figure). Specifically, the type of the electronic device is set according to the type of the electronic device. In this embodiment, the electronic device is a projector, and accordingly, the electronic device includes a projection component. It can be understood that in other embodiments, the specific type of the electronic device can also be set according to the requirements, and the electronic device only needs to have the installation requirements of the speaker 200.

[0053] The speaker installation structure 100 includes a housing 110, at least one first elastic block 120 and at least one second elastic block 130. The housing 110 has a first inner wall 111, a second inner wall 112 and a receiving cavity 113 defined between the first inner wall 111 and the second inner wall 112. The first elastic block 120 and the second elastic block 130 are both arranged in the receiving cavity 113, and the first elastic block 120 is connected to the first inner wall 111, and the second elastic block 130 is connected to the second inner wall 112. The first elastic block 120 and the second elastic block 130 cooperate with each other to limit the speaker 200 to be locked in the receiving cavity 113. Since the speaker 200 is limited in the accommodating cavity 113 by the cooperation and engagement of the first elastic block 120 and the second elastic block 130, not only the elastic effect of the elastic blocks is used to achieve effective vibration isolation, but also there is no need to provide an inner concave notch on the speaker 200 that greatly occupies the volume of the speaker 200, which helps to ensure the bass effect of the speaker 200. At the same time, the speaker installation structure 100 is simpler, which helps to reduce material costs and improve installation efficiency.

[0054] The speaker installation structure 100 provided in this embodiment is further described below:

[0055] Please continue to refer to Figure 1 and Figure 2 In this embodiment, the housing 110 includes a housing body 114 and an upper cover 115, and the housing body 114 and the upper cover 115 are covered to form a receiving chamber 113. The bottom wall of the housing body 114 is the first inner wall 111, and the inner top surface of the upper cover 115 is the second inner wall 112. Specifically, the housing body 114 also has a side wall arranged around the bottom wall, so as to form a square box shape with an open upper end. The upper cover 115 is generally in the shape of a plate, which covers the upper end of the housing body 114, so as to close the opening of the upper end of the housing body 114 to form a closed receiving chamber 113. The first inner wall 111 is the bottom wall of the shell body 114, that is, the first elastic block 120 is arranged at the bottom wall of the shell body 114, and the second inner wall 112 is the inner top surface of the upper cover 115, that is, the second elastic block 130 is arranged at the inner top surface of the upper cover 115, so that the first inner wall 111 and the second inner wall 112 are relatively spaced apart, and the first elastic block 120 and the second elastic block 130 are spaced apart in the up and down directions, so that the speaker 200 is limited and fixed between the first elastic block 120 and the second elastic block 130 by clamping the first elastic block 120 and the second elastic block 130 up and down.

[0056] There are multiple first elastic blocks 120, and the multiple first elastic blocks 120 surround a first engaging area 140 (such as Figure 3 There are multiple second elastic blocks 130, and the multiple second elastic blocks 130 surround a second engaging area (not shown) for matching with the top of the sound box 200.

[0057] Figure 3 This is a schematic diagram of the structure inside the shell body 114 of the speaker installation structure 100 provided in this embodiment. Figure 1-Figure 3 , a plurality of first elastic blocks 120 are correspondingly engaged at a plurality of corners of the bottom of the speaker 200, and a plurality of second elastic blocks 130 are correspondingly engaged at a plurality of corners of the top of the speaker 200. In this embodiment, the speaker 200 is roughly in the shape of a rectangular parallelepiped, so the bottom of the speaker 200 has four corners, and the top of the speaker 200 also has four corners. Accordingly, the number of the first elastic blocks 120 is four, and the four first elastic blocks 120 are respectively used to engage at the four corners of the bottom of the speaker 200, that is, the four first elastic blocks 120 are distributed in a rectangular array on the first inner wall 111, so that the first engaging area 140 surrounded is rectangular. The four first elastic blocks 120 can realize the limiting fixation of the bottom of the speaker 200. The number of the second elastic blocks 130 is four, and the four second elastic blocks 130 are respectively used to engage at the four corners of the top of the speaker 200, that is, the four second elastic blocks 130 are distributed in a rectangular array on the second inner wall 112, so that the second engaging area surrounded is rectangular. When the upper cover 115 is covered on the shell body 114, the upper cover 115 presses the second elastic block 130 against the speaker 200, and the top of the speaker 200 can be limited and fixed by the four second elastic blocks 130. In this way, the installation and fixation of the speaker 200 is achieved by the mutual cooperation of the four first elastic blocks 120 and the four second elastic blocks 130.

[0058] It should be noted that the number of the first elastic blocks 120 and the second elastic blocks is not limited here. It can be understood that in other embodiments, the number of the first elastic blocks 120 and the second elastic blocks 130 can also be increased or decreased accordingly according to the shape of the speaker 200. For example, when the speaker 200 is in the shape of a triangular prism, the number of the first elastic blocks 120 and the second elastic blocks 130 can also be set to three accordingly. When the speaker 200 is in the shape of a pentagonal prism, the number of the first elastic blocks 120 and the second elastic blocks 130 can also be set to five accordingly.

[0059] After the speaker 200 is locked and limited in the accommodating cavity 113, there is a gap between the wall surface of the speaker 200 and the inner wall of the outer shell 110. Specifically, through the support of the first elastic block 120 and the second elastic block 130, the bottom wall and the top wall of the speaker 200 respectively maintain a safety gap with the first inner wall 111 and the second inner wall 112 of the outer shell 110, thereby ensuring the vibration isolation effect. Optionally, the safety gap d ≥ 2mm. Furthermore, 2mm ≤ d ≤ 4mm, that is, the safety gap can be 2mm, 3mm, 4mm, etc., which can not only ensure the vibration isolation effect of the speaker 200, but also avoid the problem of increasing the size of the outer shell 110 or reducing the size of the speaker 200 due to an excessively large safety gap.

[0060] Figure 4 This is a schematic diagram of the appearance structure of the speaker 200 provided in this embodiment. Figure 5 This is a schematic diagram of the structure of the first elastic block 120 in the speaker installation structure 100 provided in this embodiment at a first viewing angle. Figure 1-Figure 5 Furthermore, a first recessed portion 210 is provided at the corner of the speaker 200, and the first elastic block 120 and the second elastic block 130 have a first engaging step 122 adapted to the first recessed portion 210. By providing the first recessed portion 210 corresponding to the first elastic block 120 and the second elastic block 130 at the corner of the speaker 200, the thickness of the first elastic block 120 and the second elastic block 130 can be increased while ensuring that the safety gap remains unchanged, which helps to improve the vibration isolation effect. At the same time, the cooperation between the first recessed portion 210 and the first elastic block 120 and the second elastic block 130 helps to ensure the fixed position effect of the speaker 200 and prevent the speaker 200 from shaking. Specifically, a first recessed portion 210 is provided at each of the eight corners of the speaker 200, and the four first elastic blocks 120 and the four second elastic blocks 130 all have a first engaging step 122 adapted to the first recessed portion 210. Optionally, the structures of the four first elastic blocks 120 and the four second elastic blocks 130 are substantially the same.

Optionally, the first boss portion 1251 and the second boss portion 1252 are connected to each other, and the cross section of the limiting boss 125 formed in this way is L-shaped.

[0066] Furthermore, a guide surface 126 is provided on the limiting boss 125, and along the direction from the limiting boss 125 to the assembly platform 121, the guide surface 126 is inclined toward the direction close to the matching space, so as to guide the corner into the matching space during matching. Specifically, a first guide surface 1261 is provided on the first boss portion 1251, and a second guide surface 1262 is provided on the second boss portion 1252. The first guide surface 1261 and the second guide surface 1262 form a trumpet-shaped opening to guide the corner into the matching space, so as to facilitate the engagement of the first elastic block 120 with the speaker 200.
