Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. 1-11 are diagrams of related embodiments of the electronic device 100 in this application.

The electronic device 100 produces outgoing sound from the speaker assembly. In the related art, a speaker assembly includes a speaker, a front case and a rear case. The speaker is used to emit sound, a front sound cavity is defined between the speaker and the front shell, and a rear sound cavity is defined between the speaker and the rear shell. Since the rear sound cavity of the speaker assembly in the related art is small, the expressiveness of the bass of the speaker assembly is not good.

This embodiment provides an electronic device 100, and the electronic device 100 can be any electronic device 100 with a sound external function, such as a mobile phone, tablet, MP3 player, MP4 player, telephone landline, electronic watch, electronic calculator etc. Compared with the above-mentioned related art, the electronic device 100 in this embodiment has the advantages that the speaker assembly 160 occupies less space and has better sound quality.

The electronic device 100 specifically includes a housing, a packing member 170 and a speaker assembly 160 .

The housing defines an internal chamber 130 in which the internal electronic components of the electronic device 100 are disposed. Specifically, the casing may include an outer casing and an inner casing of the electronic device 100 , and the casing may define one internal chamber 130 , or may define multiple internal chambers 130 . For example, when the electronic device 100 is a mobile phone, both the middle frame 120 and the battery cover 110 of the mobile phone can be referred to as the housing of the electronic device 100 . An inner chamber 130 is respectively limited between the middle frame 120 of the mobile phone and the battery cover 110 and between the middle frame 120 of the mobile phone and the front glass panel.

The packing member 170 is disposed in the inner chamber 130 and isolates the acoustic chamber 131 in the inner chamber 130 . That is, the sounding chamber 131 is a part of the inner chamber 130 and exists independently from other spaces of the inner chamber 130 , and is isolated from the other spaces of the inner chamber 130 by the sealing member 170 .

The packing 170 may isolate the acoustic chamber 131 alone or may isolate the interior chamber 130 together with other components within the interior chamber 130 . It should be noted that anything that can function to isolate the acoustic chamber 131 in the interior chamber 130 can be referred to as a packing 170 .

When the packing member 170 isolates the sound chamber 131 alone, the packing member 170 may be a plate-shaped member that completely covers a certain section of the inner chamber 130 (ie, the projection of the packing member 170 in the direction perpendicular to the above-mentioned section is completely (covering the above-mentioned section), so as to isolate the inner chamber 130 into two mutually independent spaces, and one of the spaces is the sounding chamber 131 where the speaker assembly 160 is arranged.

When the spacer 170 isolates the acoustic chamber 131 together with other components in the inner chamber 130, the spacer 170 can completely cover the aforementioned cross-section together with other internal elements in the inner chamber 130 (it can also be understood as an isolation 170 fills the void created between the original internal element and the housing).

The packing 170 can be fixedly connected with the housing, or can be detachably connected with the housing. When the packing member 170 is fixedly connected with the casing, the packing member 170 may be thermally fused to the casing. When the packing member 170 is detachably connected to the housing, it can be glued, screwed, snapped or just abutted with the housing. In particular, the packing member 170 can also be integrally injection-molded with the housing, and the packing member 170 is a plate-shaped flange that completely covers a certain section of the inner chamber 130 .

The speaker assembly 160 is disposed in the sounding chamber 131 . The speaker assembly 160 includes a front case 161 and a speaker 162 positioned on the front case 161 , and the speaker 162 and the front case 161 together define a front sound cavity 1311 of the speaker assembly 160 . The speaker assembly 160 in the present embodiment does not have a rear shell, and uses the remaining space of the sound chamber 131 as the rear sound chamber 1312 of the speaker assembly 160 .

Compared with the structure of the speaker assembly 160 in the related art, in the first aspect, the speaker assembly 160 in this embodiment has fewer components, so it occupies less space in the electronic device 100 . In the second aspect, since the rear shell of the speaker assembly 160 is removed, the manufacturing cost of the speaker assembly 160 is reduced. In the third aspect, in this embodiment, the remaining space of the sounding chamber 131 is used as the rear sound cavity 1312 of the speaker assembly 160 , so that the volume of the rear sound cavity 1312 is larger and the expressive power of bass is stronger. In the fourth aspect, this embodiment does not use all the remaining space of the internal cavity 130 of the electronic device 100 as the rear sound cavity 1312 of the speaker assembly 160, but isolates the sound-emitting cavity 131 in the internal cavity 130, and separates the sound-emitting cavity 131 is used as the rear sound cavity 1312 of the speaker assembly 160, such a structure prevents the sound emitted by the speaker 162 from being transmitted to the position where the spatial structure of the internal cavity 130 is more complicated (for example, when the electronic device 100 is a mobile phone, the internal cavity 130 of the mobile phone The upper end of the mobile phone is close to the handset of the mobile phone due to the structure of the camera assembly, phone card slot, phone card tray, etc., its spatial structure is relatively complex), which prevents the sound introduced into the above-mentioned complex position from being reflected in multiple different directions and resulting in more cluttered self-interference. distorts the sound. Therefore, the sound-emitting chamber 131 with a relatively regular spatial structure is isolated by the packing member 170 , and the structure of the sound-emitting chamber 131 as the rear sound chamber 1312 of the speaker assembly 160 can further improve the sound quality of the speaker assembly 160 .

In the related art, in order to prevent the internal components in the internal cavity 130 (here, it specifically refers to the internal cavity 130 except for the packing 170 and other components of the speaker assembly 160 ) after being assembled in the housing, there is a positional interference between the housing and the housing. , there is a certain gap between the internal components in the internal chamber 130 and the casing of the electronic device 100 after the assembly is completed. The above-mentioned gaps make the internal cavity 130 of the electronic device 100 communicate with each other, and the sound generated by the speaker assembly 160 is easy to pass through the above-mentioned gaps and travel around the electronic device 100 .

In this embodiment, in order to prevent the sound emitted by the speaker assembly 160 from flowing to the position where the structure of the internal cavity 130 is more complicated, the packing member 170 can be in the shape of a strip, and the packing member 170 is configured to fill the gap between the internal element and the casing by filling The sound-emitting chamber 131 is sealed off by the gap between them, so that the sound emitted by the speaker assembly 160 is only vibrated in the sound-emitting chamber 131 . That is, the packing 170 does not need to completely cover the entire section of the inner chamber 130 , it only needs to cover the gap between the inner elements in the inner chamber 130 and the inner wall of the housing. Such a structure can reduce the space occupied by the packing 170 and also reduce the design difficulty of the packing 170 (the structure and positional arrangement of the packing 170 do not affect other internal components, so the design of the packing 170 It is not necessary to consider the interference to other components in the electronic device 100 when the structure is configured).

When the packing member 170 is in the shape of a strip, it can be set to have elasticity, and the packing member 170 is elastically deformed after filling the gap between the casing and the internal elements of the electronic device 100 . When the packing member 170 fills the above-mentioned gap, one side presses against the inner wall surface of the casing facing the packing member 170 , and the other side presses against the internal elements in the inner chamber 130 . The packing member 170 can sufficiently fill the gap between the inner element in the inner chamber 130 and the housing through elastic deformation, so as to achieve better sealing performance.

The packing member 170 can be made of any existing elastic material, and specifically, it can be a high compression ratio foam. The high compression ratio foam has a high compression rate, on the one hand, it can seal the gap between the internal elements in the inner chamber 130 and the shell, and on the other hand, it can reduce the vibration of the internal elements in contact with it, and improve the Shock resistance of the electronic device 100 . It should be noted that in this embodiment, the elastic foam with a compressibility greater than or equal to 50% is called a high compression ratio foam, that is, on the premise of not losing the function of the foam, the high compression ratio foam The volume can be compressed to at least half of the maximum volume state.

When the packing member 170 is the above-mentioned high compression ratio foam, it can abut with the parts of the electronic device 100 that are more sensitive to vibration, so as to reduce the vibration of the above-mentioned parts and protect the above-mentioned parts. Specifically, when the electronic device 100 is a mobile phone, the high compression ratio foam can be in contact with the battery 140 of the mobile phone, so as to reduce the vibration amplitude of the mobile phone battery 140 and improve the safety performance of the mobile phone.

As shown in FIGS. 1 to 11 , the electronic device 100 may specifically be a mobile phone, and the electronic device 100 to which the present application is applied will be introduced by taking the mobile phone as an example below.

The power supply can be logically connected to the processor through the power management system, so that the functions of managing charging, discharging, and power consumption are realized through the power management system. Although not shown, the mobile phone may also include a Bluetooth module, etc., which will not be repeated here.

The mobile phone further includes a battery cover 110 and a middle frame 120 (both the battery cover 110 and the middle frame 120 can be understood as part of the casing of the aforementioned electronic device 100 ). The middle frame 120 is connected with the battery cover 110 , and together with the battery cover 110 defines the aforementioned internal cavity 130 . The packing member 170 is disposed in the inner chamber 130 to isolate the inner chamber 130 into two relatively independent spaces, and one of the spaces is the sounding chamber 131 where the speaker assembly 160 is arranged.

The packing 170 can isolate the sound chamber 131 alone or can isolate the internal chamber 130 together with other components in the internal chamber 130 of the mobile phone. It should be noted that any component that can function to isolate the acoustic chamber 131 in the interior chamber 130 of the handset can be referred to as a packing member 170 .

When the packing 170 isolates the sound-emitting chamber 131 together with other components within the handset interior cavity 130, the packing 170 is configured to isolate the sound-emitting chamber 131 by filling the gap between the internal elements and the housing, allowing the speaker assembly The sound emitted by 160 vibrates only in the sounding chamber 131 . That is, the packing 170 does not need to completely cover the entire section of the mobile phone internal cavity 130 , but only needs to cover the gap between the internal elements in the mobile phone internal cavity 130 and the inner wall of the battery cover 110 .

The mobile phone further includes a battery 140 disposed in the inner chamber 130 . There is a risk of short circuit when the battery 140 of the mobile phone generates a large vibration. In order to reduce the vibration of the battery 140 of the mobile phone, the sealing member 170 may abut against the battery 140 of the mobile phone. One side of the packing member 170 is in contact with the surface of the battery 140 facing the battery cover 110 , and the other side is in contact with the battery cover 110 , and is elastically deformed to simultaneously generate a pressing force on the battery cover 110 and the battery 140 . The elastic packing member 170 can buffer the vibration generated by the battery 140 in the mobile phone, and the pressing force generated by the packing member 170 on the battery 140 can reduce the vibration amplitude of the battery 140 and reduce the risk of short circuit of the battery 140 due to vibration. .

The packing 170 extends along the width direction of the mobile phone, and together with the battery 140 divides the internal chamber 130 into a first accommodating chamber and a second accommodating chamber, the first accommodating chamber is close to the earpiece of the mobile phone, and the second accommodating chamber Move away from the handset. That is, the two ends of the packing member 170 are respectively in contact with the two ends of the inner cavity 130 along the width direction, so as to divide the remaining space in the inner cavity 130 of the mobile phone into upper and lower parts (the part of the mobile phone close to the earpiece is the upper part, The part close to the charging socket is the lower part, the upper part is the first accommodating chamber close to the handset of the mobile phone, and the lower part is the second accommodating chamber far from the handset of the mobile phone. Since there are many components in the first accommodating chamber and the remaining space is small, in this embodiment, the second accommodating chamber is the aforementioned sounding chamber 131 , that is, the speaker assembly 160 is disposed in the space below the packing member 170 .

The front case 161 of the speaker assembly 160 can be fixed on the battery cover 110 , as shown in FIG. The wall surface of the front case 161 away from the battery cover 110 is formed with a sink 1611, the speaker 162 is embedded in the sink 1611, and the speaker 162 is fixed to the front case 161 by bonding with the surface wall of the sink 1611, which can be understood as a speaker The assembly 160 is integrally fixed on the battery cover 110 of the mobile phone. The speaker assembly 160 is fixed on the battery cover 110 to prevent the vibration generated by the speaker assembly 160 from being transmitted to the battery 140 of the mobile phone. In addition, since the cell phone battery cover 110 and the cell phone battery 140 are in contact with each other by the compression ratio foam, the high compression ratio foam can reduce the vibration of the cell phone battery cover 110 (the vibration is mainly generated by the speaker assembly 160 ).

After the speaker assembly 160 is installed on the battery cover 110 , in order to improve the stability of the speaker assembly 160 , an abutting member (not shown in the figure) may also be provided between the speaker 162 of the speaker assembly 160 and the middle frame 120 of the mobile phone. The connector has elasticity, one end abuts the speaker 162 and the other end abuts against the middle frame 120 of the mobile phone, and elastically deforms after abutting the middle frame 120 and the speaker 162 of the mobile phone, so that the abutting member pushes the speaker 162 to the front case 161, so that the positioning of the speaker assembly 160 is more stable. In particular, the abutment can also be made of high compression ratio foam.

In particular, in order to further reduce the occupied space of the speaker assembly 160 , the front case 161 of the speaker assembly 160 may be integrally formed with the battery cover 110 of the mobile phone, and specifically may be integrally injection-molded. When the front case 161 and the battery cover 110 are integrally formed, only a sink 1611 structure for fixing the speaker 162 needs to be provided on the battery cover 110 (the sink 1611 structure can be along the surface wall of the battery cover 110 facing the speaker 162 toward the speaker 162 . The annular flange extending in the direction is sufficient, which reduces the space occupied by the front case 161 .

The middle frame 120 has a connection slot 121 extending along the length direction of the mobile phone, and a connection wire 150 is arranged in the connection slot 121 . The connecting wire 150 is used to provide electrical power to the electronic components in the second accommodating chamber. The wiring slot 121 communicates with the first accommodating chamber and the second accommodating chamber. Although the wiring slot 121 is provided with a connecting wire 150, the connecting wire 150 cannot completely cover the cross section of the wiring slot 121 (perpendicular to the wiring slot). 121 in the longitudinal direction), so the sound from the speaker assembly 160 located in the second accommodating chamber is likely to be guided to the first accommodating chamber through the wiring slot 121, thereby causing sound distortion.

As shown in FIG. 3 , in order to seal the connection groove 121 , the connection wire 150 can be sheathed with an elastic rubber ring 151 , and the elastic rubber ring 151 completely fills the gap between the connection groove 121 and the connection groove 121 . At the same time, the elastic rubber ring 151 can be made of an elastic material. After it is installed in the wiring groove 121, it is elastically deformed by squeezing the wall surface of the wiring groove 121 to fully cover the cross section of the wiring groove 121 (perpendicular to the The cross section in the longitudinal direction of the wiring slot 121). Specifically, the elastic rubber ring 151 may be made of materials such as rubber or silicone.
