Before the technical solutions of the present application are introduced, the technical problems in the related art will be described in detail.

In the related art, especially during the assembly of electronic equipment, it is often necessary to use a seal to bond the speaker to the housing to form a closed sound outlet channel. For example, electronic devices such as smartwatches and earphones often adopt a light and thin design, and the internal space for mounting the speaker is small, so that the sealing member is often manually bonded to the housing, and then the speaker is bonded to the housing to seal the speaker. However, since manual bonding is difficult to control the bonding effect, bubbles are easily generated between the speaker and the sealing member or the pressing force to the sealing member during bonding is insufficient, so that the compression amount of the sealing member is insufficient, and further, the airtightness between the speaker and the sealing member or between the housing and the sealing member is poor, a closed sound outlet channel cannot be formed, and the acoustic performance is reduced.

Alternatively, the shape of the second through-hole 201 may match the shape of the first through-hole 103. The structure of the elastomeric seal 20 will be described in detail below. Specifically, the second through hole 201 in the present embodiment is also circular, and forms a sound outlet channel 302a for propagating sound in cooperation with the first through hole 103. Optionally, the second through hole 201 is not smaller than the first through hole 103 to improve the acoustic performance of the sound transmission channel 302 a. Acoustic properties include, but are not limited to, loudness, pitch, audio, and the like.

The electronic device 1 provided by the present embodiment further includes a speaker 30, and the speaker 30 is generally configured to convert an electrical signal into an acoustic signal, so as to emit sound, and the sound can be finally transmitted to the outside through the sound output channel 302 a. The speaker 30 may be used in electronic devices 1 including, but not limited to, headsets, smart watches, smart bracelets, and the like. The speaker 30 provided herein may be any shape of component, and is not limited in this application. The speaker 30 includes a speaker body 301 and a sound outlet hole 302, wherein the sound outlet hole 302 is used for emitting an acoustic signal. The sound outlet hole 302 is closer to the elastic seal member 20 than the speaker body 301. Specifically, in the present embodiment, the speaker 30 is bonded to the second bonding portion 204 of the elastic sealing member 20, and the sound outlet hole 302 is correspondingly connected to the second through hole 201, so that the sound outlet hole 302 is connected to the sound outlet passage 302 a. Optionally, the second through hole 201 is not smaller than the sound outlet hole 302 so as to better transmit the sound to the outside.

The electronic device 1 provided by the present embodiment further includes a fixing member 40, the fixing member 40 can perform a fixing function, and the material of the fixing member 40 includes, but is not limited to, plastic, metal, and the like. The fixing element 40 provided in the present application may be any shape, and the present application does not limit this, and only the fixing element 40 needs to be provided with an accommodating groove 401 capable of accommodating at least a sub-speaker 30, and two sides of the accommodating groove 401 are respectively provided with a second positioning portion 402 and a second fixing portion 403 in a protruding manner, and the second positioning portion 402 and the second fixing portion 403 are respectively disposed corresponding to the first positioning portion 104 and the first fixing portion 105. Alternatively, the shape of the receiving groove 401 may match the shape of the speaker 30. Alternatively, the second positioning portion 402 and the second fixing portion 403, and the fixing member may be an integrally formed structural member. However, for the sake of understanding, the names of the second positioning portion 402, the second fixing portion 403, and the fixing member are artificially different. The structures of the second positioning portion 402 and the second fixing portion 403 will be described in detail below. Specifically, as shown in fig. 1, when the fixing element 40 in the present embodiment is disposed between the first positioning portion 104 and the first fixing portion 105, and at least a portion of the speaker 30 is disposed in the accommodating groove 401, at this time, the second positioning portion 402 is engaged with the first positioning portion 104, and the second fixing portion 403 is fixed to the first fixing portion 105, so that the fixing element 40 applies a pressing force to the elastic sealing element 20 through the speaker 30 to compress the elastic sealing element 20. The vertical distance from the surface of speaker 30 on the side close to fixing member 40 to the surface of elastic sealing member 20 on the side close to extension 102 before fixing member 40 is attached is greater than the vertical distance from the surface of speaker 30 on the side close to fixing member 40 to the surface of elastic sealing member 20 on the side close to extension 102 when fixing member 40 is attached, which is caused by the deformation of elastic sealing member 20 under a pressing force, and therefore, it can also be understood that the radial dimension of elastic sealing member 20 under no pressing force (as shown in H3 in fig. 7) is greater than the radial dimension of elastic sealing member 20 under a pressing force (as shown in H1 in fig. 2). As shown in fig. 6, the fixing member 40 having the second positioning portion 402 and the second fixing portion 403 is additionally provided, and the first positioning portion 104 and the first fixing portion 105 are correspondingly provided in the housing 10. The second positioning portion 402 can limit the fixing element 40 to the first positioning portion 104, the fixing element 40 can rotate relative to the first positioning portion 104, and the second fixing portion 403 and the first fixing portion 105 can be fixed to each other. During assembly, it is generally necessary to bond the elastomeric seal 20 to the housing 10 before bonding the speaker 30 to the elastomeric seal 20. Therefore, the second positioning portion 402 can be limited to the first positioning portion 104, and then the fixing element 40 is rotated, it can be understood that, by the second positioning portion 402 being coupled with the first positioning portion 104, the end of the fixing element 40 provided with the second positioning portion 402 is limited on the casing 10, at this time, by rotating the second positioning portion 402, the fixing element 40 is rotated relative to the casing 10, and then the second fixing portion 403 and the first fixing portion 105 are mutually fixed, that is, the second fixing portion 403 is rotated toward the direction close to the first fixing portion 105 (as shown in the direction of D1 in fig. 6), and the second fixing portion 403 and the first fixing portion 105 are fixed, and finally the fixing element is fixed. At this time, at least a part of the speaker 30 is disposed in the receiving groove 401, and the speaker 30 is closely adhered to the elastic sealing member 20. Therefore, the fixing member 40 is fixed to the housing 10 by the cooperation of the fixing member 40 and the positioning portion and the fixing portion of the housing 10, so that the speaker 30 is tightly adhered to the elastic sealing member 20, which can be understood as that the fixing member 40 gives a pressing force (as shown by F in fig. 1) to the elastic sealing member 20 through the speaker 30, thereby compressing the elastic sealing member 20, and the elastic sealing member 20 fills up and seals gaps between the elastic sealing member 20 and the housing 10 and the speaker 30 by its repulsive force, thereby improving the air-tightness, forming the closed sound outlet channel 302a, and improving the acoustic performance. Alternatively, the second fixing portion 403 and the first fixing portion 105 may be fixed by a snap manner, or may be fixed by a screw manner, and the embodiment is not limited herein.

In addition, when the second positioning portion 402 is limited on the first positioning portion 104 and the fixing element 40 is continuously rotated toward the direction close to the first fixing portion 105, the fixing element 40 gradually accommodates at least a portion of the speaker 30 in the accommodating groove 401 of the fixing element 40, that is, during the continuous rotation of the fixing element 40, at least a portion of the speaker 30 is gradually accommodated in the accommodating groove 401, it can also be understood that the extrusion force applied to the elastic compression element is gradually increased through the speaker 30, so as to avoid the extrusion force applied to the elastic compression element at one time, and thus the speaker 30 is prevented from being damaged. And then the second fixing portion 403 and the first fixing portion 105 are fixed to each other to achieve sealing.

Specifically, the sealing effect is influenced by the size of the seal, the radial dimension of the seal (as indicated by H3 in fig. 7), the positions of the first positioning portion 104 and the first fixing portion 105 provided in the housing 10, the radial dimension of the housing groove 401 (as indicated by H2 in fig. 5), and the like. Generally, better acoustic performance of the product is achieved when the elastomeric seal 20 is compressed by 30% -50% during assembly. By considering these factors, the electronic apparatus 1 according to the present embodiment is designed such that the fixing member 40 compresses the elastic sealing member 20 by 30% to 50%, thereby improving the airtightness, improving the acoustic performance, and improving the product quality.

The structure can limit the fixing member 40 on the casing 10 simply and conveniently, so that the fixing member 40 can rotate relative to the casing 10 to accommodate the loudspeaker 30 into the accommodating groove 401 gradually, thereby gradually increasing the extrusion force given to the elastic compression member, avoiding giving the extrusion force to the elastic compression member at one time and further avoiding damaging the loudspeaker 30.
