Description

Technical Field

[0001] The present disclosure relates to the technical field of electronic equipment, and in particular to a terminal device. Background Art

[0002] The speaker is an important component in the terminal device. It is used for electro-acoustic conversion and is the sound-producing component of the terminal device.

[0003] Usually, the speaker is connected to the side of the screen module close to the middle frame. The speaker vibrates under the action of electric energy and makes sound. The vibration is transmitted to the screen module to transmit the sound, thereby realizing the sound of the terminal device.

[0004] However, the screen module usually includes foam and a cover plate. The speaker and the middle frame are connected to one side of the foam, and the other side of the foam is connected to the cover plate. Although this achieves a fixed connection between the speaker and the screen module, the foam mainly plays a buffering role between the screen module and the middle frame. Therefore, the loudness of the sound will be reduced when the sound is transmitted between the speaker and the screen module, thereby affecting the sound effect of the terminal device.

[0049] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0050] The present disclosure provides a terminal device, see Figure 1 The terminal device includes a middle frame 1, a screen module 2, a first speaker 3 and a first sound transmitting component 4.

[0051] The middle frame 1 is used to support other components in the terminal device, so as to facilitate the installation of other components. The middle frame has a flat plate structure, and the surfaces on both sides of the flat plate structure can be used to connect and fix other components.

[0052] The material of the middle frame 1 can be any reasonable material such as plastic, metal or alloy, and the embodiment of the present disclosure does not specifically limit this.

[0053] The screen module 2 is used for displaying images. The screen module 2 includes a foam 21 and a cover plate 22 . The foam 21 is located on one side of the middle frame 1 and connected to the middle frame 1 . The cover plate 22 is located on a side of the foam 21 away from the middle frame 1 and connected to the foam 21 .

[0054] Among them, the middle frame 1, the foam 21, and the cover plate 22 can be stacked and connected in sequence to form a stacked structure, and the plane where the middle frame 1 is located, the plane where the foam 21 is located, and the plane where the cover plate 22 is located can all be arranged in parallel, and the cross-sections in the various drawings in the present disclosure are cross-sections perpendicular to the plane where the cover plate 22 is located (or the plane where the middle frame 1 is located, or the plane where the foam 21 is located). It can be understood that the connection here can be direct contact, connection, or connection achieved through other film layers, which will be described in detail later and will not be repeated here.

[0055] The cover plate 22 is a glass cover plate. Of course, the cover plate 22 can also be made of other reasonable materials, which is not specifically limited in the embodiment of the present disclosure.

[0056] See also Figure 1 The first speaker 3 is located on a side of the foam 21 close to the middle frame 1 .

[0057] See also Figure 1 , Figure 2 and Figure 4 , the foam 21 has a first through hole 211. Figure 1 , Figure 3 and Figure 4 The first sound transmitting member 4 is located between the first speaker 3 and the cover plate 22 , penetrates through the first through hole 211 , and is connected to the first speaker 3 and the cover plate 22 , respectively.

[0058] That is, when the first speaker 3 vibrates, the vibration is effectively transmitted to the cover plate 22 mainly through the first sound transmitting member 4, so as to realize the sound transmission from the first speaker 3 to the cover plate 22, thereby avoiding the phenomenon that the loudness of the sound is weakened by the foam 21 when the sound is transmitted through the foam 21, so that the user can hear louder sound through the cover plate 22, thereby improving the sound effect of the terminal device.

[0059] In the embodiment of the present disclosure, the material of the first sound transmission element 4 can be any reasonable material with good sound transmission effect, for example, it can be acrylic, glass, etc., and the embodiment of the present disclosure does not specifically limit this.

[0060] In the embodiment of the present disclosure, the first speaker 3 may be any device that generates sound through vibration conduction, for example, it may be a piezoelectric ceramic, an actuator, etc., and the embodiment of the present disclosure does not specifically limit this.

[0061] Next, several possible structures of the first through hole 211 and the first sound transmitting member 4 are introduced:

[0062] In one possible implementation, the first through hole 211 may be a simple circular through hole or a square through hole, and the shape and size of the first through hole 211 in each cross section parallel to the plane where the foam 21 is located are the same. Correspondingly, the shape of the first sound transmitting element 4 may be a cylinder or a cuboid that matches the shape of the first through hole 211. Of course, the shapes of the first through hole 211 and the first sound transmitting element 4 may also be other reasonable shapes, and the embodiments of the present disclosure do not specifically limit this.

[0063] In another possible implementation, see Figure 2 The first through hole 211 may include a first hole portion 2111 and a second hole portion 2112 that are connected to each other. The second hole portion 2112 is located on a side of the first hole portion 2111 away from the middle frame 1 , and a cross-sectional area of ​​the second hole portion 2112 is greater than a cross-sectional area of ​​the first hole portion 2111 .

[0064] It is understandable that in Figure 2 In the figure, the first hole portion 2111 and the second hole portion 2112 connected to each other are distinguished by a dotted line. Figure 1 and Figure 2 It can be seen that one end of the first hole portion 2111 is located on the surface of the foam 21 close to the first speaker 3 and is connected to the first speaker 3, the other end of the first hole portion 2111 is connected to one end of the second hole portion 2112, and the other end of the second hole portion 2112 is located on the surface of the foam 21 close to the cover plate 22 and is connected to the cover plate 22.

[0065] See also Figure 1 , Figure 3 and Figure 4 Correspondingly, the first sound transmitting member 4 includes a first conducting portion 41 and a second conducting portion 42. The shape of the first conducting portion 41 is adapted to the shape of the first hole portion 2111 and is penetrated in the first hole portion 2111. The shape of the second conducting portion 42 is adapted to the shape of the second hole portion 2112 and is penetrated in the second hole portion 2112.

[0066] It is understandable that in Figure 3 In FIG. 4 , the first conductive part 41 and the second conductive part 42 are distinguished by a dotted line; Figure 4 In FIG. 1 , the first hole portion 2111 and the second hole portion 2112 are distinguished by a dotted line, and the first conduction portion 41 and the second conduction portion 42 are distinguished.

[0067] The first speaker 3 , the first conduction part 41 , the second conduction part 42 , and the cover plate 22 are connected in sequence, that is, one end of the first conduction part 41 is connected to the first speaker 3 , the other end of the first conduction part 41 is connected to one end of the second conduction part 42 , and the other end of the second conduction part 42 is connected to the cover plate 22 .

[0068] In this way, since the cross-sectional area of ​​the second hole portion 2112 is larger than the cross-sectional area of ​​the first hole portion 2111, on the one hand, a T-shaped first through hole 211 is formed, which improves the connection stability between the first sound transmitting component 4 and the foam 21, and on the other hand, the connection area between the second conduction portion 42 and the cover plate 22 is increased, which further improves the stability and effect of sound conduction, improves the loudness of the conducted sound, and thus improves the sound effect of the terminal device.

[0069] The above are only two possible structural arrangements of the first through hole 211 and the first sound transmitting member 4 , which may also be any other reasonable structure, and the embodiments of the present disclosure are not limited thereto.

[0070] Several possible structures of the middle frame 1 and the first speaker 3 are introduced below:

[0071] In one possible implementation, see Figure 1 A side of the middle frame 1 close to the foam 21 has a groove 11, and the first speaker 3 is located in the groove 11. The first speaker 3 is reasonably arranged in space by partially avoiding the middle frame 1.

[0072] Furthermore, the first speaker 3 has no contact with the inner wall of the groove 11, so that the first speaker 3 can directly transmit the sound to the cover plate 22 for sound production, instead of transmitting the vibration to the middle frame 1 for sound production, thereby avoiding the occurrence of sound diffusion caused by the sound production of the middle frame 1, improving the sound effect of the terminal device, and improving the user experience.

[0073] In another possible implementation, see Figure 5 The middle frame 1 has a second through hole 12, and the first speaker 3 is inserted into the second through hole 12. The second through hole 12 is provided to achieve a reasonable arrangement of the first speaker 3 in space.

[0074] Furthermore, the first speaker 3 has no contact with the inner wall of the second through hole 12, so that the first speaker 3 can directly transmit the sound to the cover plate 22 for sound production, instead of transmitting the vibration to the middle frame 1 for sound production, thereby avoiding the occurrence of sound diffusion caused by the sound production of the middle frame 1, improving the sound effect of the terminal device, and improving the user experience.

[0075] Next, the connection structure between the middle frame 1, the foam 21 and the cover plate 22 is introduced:

[0076] In a possible implementation, the connection between the middle frame 1 and the foam 21 can be: the screen module 2 can also include a grounding plate 23, the grounding plate 23 is located on the side of the foam 21 close to the middle frame 1, and the middle frame 1, the grounding plate 23, and the foam 21 are connected in sequence.

[0077] The grounding plate 23 is used to support other functional film layers in the screen module 2, and the grounding plate 23 can be electrically connected to the grounding terminal on the mainboard of the terminal device to achieve grounding of the screen module 2. The grounding plate 23 can be any reasonable metal material, for example, copper foil, etc., which is not limited in the embodiments of the present disclosure.

[0078] The grounding plate 23 has a third through hole 231, and the first speaker 3 is inserted into the third through hole 231. In this way, while the grounding plate 23 realizes its function, it will not affect the connection between the first speaker 3 and the first sound transmitting element 4, thereby improving the stability of the terminal device.

[0079] In another possible implementation, the connection between the middle frame 1 and the foam 21 may also be: Figure 1 The terminal device also includes foam glue 7, and the opposite sides of the foam glue 7 are respectively connected to the middle frame 1 and the foam grounding plate 23, thereby realizing the connection between the middle frame 1 and the grounding plate 23, and the grounding plate 23 and the foam 21 can be connected by adhesive, thereby realizing the connection between the middle frame 1 and the foam 21.

[0080] In a possible implementation, the connection between the foam 21 and the cover plate 22 may be: Figure 1 The screen module 2 may further include a mesh glue 24, a back plate 25, a panel 26 (panel), a polarizer 27 and an optical glue 28. The foam 21, the mesh glue 24, the back plate 25, the panel 26, the polarizer 27, the optical glue 28 and the cover plate 22 are stacked and connected in sequence, that is, the opposite sides of the mesh glue 24 are respectively connected to the foam 21 and the back plate 25, the opposite sides of the panel 26 are respectively connected to the back plate 25 and the polarizer 27, and the opposite sides of the optical glue 28 are respectively connected to the polarizer 27 and the cover plate 22, thereby realizing the connection between these functional film layers.

[0081] Of course, the above is only one of the settings of the film layer and the connection structure. The screen film group 2 may also include only one or several of the above functional film layers, or may also include other reasonable functional film layers, which is not limited in the embodiments of the present disclosure.

[0082] In one possible implementation, the first speaker 3 can be in contact with the foam 21, that is, the surface of the first sound transmitting component 4 connected to the first speaker 3 is flush with the surface of the foam 21 close to the first speaker 3. In this way, after the first speaker 3 is connected to the first sound transmitting component 4, the foam 21 can play a certain supporting role for the first speaker 3, thereby improving the stability of the terminal device.

[0083] It is understandable that, in this case, the area of ​​the first loudspeaker 3 that is connected to the first sound transmitting element 4 is not the entire area of ​​the surface of the first loudspeaker 3 that is used for connection.

[0084] Of course, the surface of the first sound transmitting element 4 connected to the first speaker 3 may be arranged to protrude from the surface of the foam 21 close to the first speaker 3. In this way, a gap is formed between the first speaker 3 and the foam 21. It can be arranged according to actual needs and spatial arrangement, and the embodiment of the present disclosure is not limited to this.

[0085] In the embodiments of the present disclosure, see Figure 6 , Figure 7 , Figure 8 and Fig. 9 The terminal device may further include a second speaker 5 and a second sound transmitting element 6 , and the foam 21 further has a fourth through hole 212 .

[0086] The second speaker 5 is located on a side of the foam 21 close to the middle frame 1 , and the second sound transmitting member 6 is located between the second speaker 5 and the cover plate 22 , penetrates through the fourth through hole 212 , and is connected to the second speaker 5 and the cover plate 22 , respectively.

[0087] That is: when sound needs to be made, the first speaker 3 and the second speaker 5 vibrate together and make sound at the same time. The first speaker 3 transmits the sound to the cover 22 through the first sound transmission member 4, and the second speaker 5 transmits the sound to the cover 22 through the second sound transmission member 6, thereby increasing the loudness of the sound transmitted to the cover 22, thereby improving the sound effect of the terminal device.

[0088] In the embodiment of the present disclosure, the first speaker 3 and the second speaker 5 can be the same type of sound-emitting devices, or different types of sound-emitting devices. For example, when the first speaker 3 and the second speaker 5 are the same type of sound-emitting devices, both can be piezoelectric ceramics or both can be exciters, and so on. When the first speaker 3 and the second speaker 5 are different types of sound-emitting devices, the first speaker 3 can be a piezoelectric ceramic, and the second speaker 5 can be an exciter. Since the piezoelectric ceramic has better high-frequency performance and greater high-frequency loudness, and the exciter has better low-frequency performance and greater low-frequency loudness, therefore, the first speaker 3 is set to be a piezoelectric ceramic and the second speaker 5 is set to be an exciter. The two can be used in combination. The exciter makes up for the low-frequency deficiency of the piezoelectric ceramic, and the piezoelectric ceramic makes up for the high-frequency deficiency of the exciter. The two complement each other. By fully covering the high and low frequencies of the two devices, it is ensured that the terminal device can effectively make sound when the high and low frequencies vibrate, thereby improving the sound effect of the terminal device.

[0089] In one possible implementation, the structural arrangement of the fourth through hole 212 and the second sound transmitting element 6 may be as follows: the fourth through hole 212 may be a simple circular through hole or a square through hole, and the shape and size of the fourth through hole 212 in each cross section parallel to the plane where the foam 21 is located are the same. Correspondingly, the shape of the second sound transmitting element 6 may be a cylinder or a cuboid that matches the shape of the fourth through hole 212. Of course, the shapes of the fourth through hole 212 and the second sound transmitting element 6 may also be other reasonable shapes, and the embodiments of the present disclosure do not specifically limit this.

[0090] In another possible implementation, the fourth through hole 212 and the second sound transmitting member 6 may also be arranged as follows: Figure 6 and Figure 7 The fourth through hole 212 includes a third hole portion 2121 and a fourth hole portion 2122 that are connected to each other. The fourth hole portion 2122 is located on a side of the third hole portion 2121 away from the middle frame 1 . The cross-sectional area of ​​the fourth hole portion 2122 is greater than the cross-sectional area of ​​the third hole portion 2121 .

[0091] It is understandable that in Figure 7 In FIG. 2 , the third hole portion 2121 and the fourth hole portion 2122 that are connected are distinguished by a dotted line. Figure 6 and Figure 7 It can be seen that one end of the third hole portion 2121 is located on the surface of the foam 21 close to the second speaker 5 and is connected to the second speaker 5, and the other end of the third hole portion 2121 is connected to one end of the fourth hole portion 2122, and the other end of the fourth hole portion 2122 is located on the surface of the foam 21 close to the cover plate 22 and is connected to the cover plate 22.

[0092] See also Figure 6 , Figure 8 and Fig. 9 Correspondingly, the second sound transmitting member 6 includes a third conducting portion 61 and a fourth conducting portion 62. The shape of the third conducting portion 61 is adapted to the shape of the third hole portion 2121, and the third conducting portion 61 is penetrated in the third hole portion 2121. The shape of the fourth conducting portion 62 is adapted to the shape of the fourth hole portion 2122, and the fourth conducting portion 62 is penetrated in the fourth hole portion 2122.

[0093] It is understandable that in Figure 8 In FIG. 6 , the third conductive part 61 and the fourth conductive part 62 are distinguished by a dotted line; Fig. 9 In FIG. 1 , the third hole portion 2121 and the fourth hole portion 2122 are distinguished by dotted lines, and the third conduction portion 61 and the fourth conduction portion 62 are distinguished.

[0094] The second speaker 5 , the third conduction part 61 , the fourth conduction part 62 , and the cover plate 22 are connected in sequence, that is, one end of the third conduction part 61 is connected to the second speaker 5 , the other end of the third conduction part 61 is connected to one end of the fourth conduction part 62 , and the other end of the fourth conduction part 62 is connected to the cover plate 22 .

[0095] In this way, since the cross-sectional area of ​​the third hole portion 2121 is larger than the cross-sectional area of ​​the fourth hole portion 2122, on the one hand, a T-shaped fourth through hole 212 is formed, which improves the connection stability between the second sound transmission component 6 and the foam 21, and on the other hand, the connection area between the fourth conduction portion 62 and the cover plate 22 is increased, further improving the stability and effect of sound conduction, and improving the loudness of the conducted sound, thereby improving the sound effect of the terminal device.

[0096] The above are only two possible structural arrangements of the fourth through hole 212 and the second sound transmitting member 6 , which may also be any other reasonable structure, and the embodiments of the present disclosure are not limited thereto.

[0097] In one possible implementation, see Figure 6 A groove 11 is provided on one side of the middle frame 1 close to the foam 21 , and the first speaker 3 and the second speaker 5 can both be located in the groove 11 . The first speaker 3 and the second speaker 5 can be reasonably arranged in space by partially avoiding the middle frame 1 .

[0098] Furthermore, the first speaker 3 does not contact the inner wall of the groove 11, and the second speaker 5 does not contact the inner wall of the groove 11. In this way, the sound diffusion caused by the sound of the middle frame 1 is avoided, the sound effect of the terminal device is improved, and the user experience is improved.

[0099] In another possible implementation, the middle frame 1 has a second through hole 12, and the first speaker 3 and the second speaker 5 are both inserted into the second through hole 12. By setting the second through hole 12, a reasonable spatial arrangement of the first speaker 3 and the second speaker 5 is achieved.

[0100] Furthermore, the first speaker 3 does not contact the inner wall of the second through hole 12, and the second speaker 5 does not contact the inner wall of the groove 11. In this way, the sound diffusion caused by the sound of the middle frame 1 is avoided, the sound effect of the terminal device is improved, and the user experience is improved.

[0101] In one possible implementation, see Figure 6 , Figure 7 , Figure 8 and Fig. 9 The first through hole 211 is connected to the fourth through hole 212, and the second sound transmission element 6 and the first sound transmission element 4 are an integrally formed structure.

[0102] In another possible implementation, see Fig.10 , Fig.11 and Fig.12 , the second sound transmitting element 6 and the first sound transmitting element 4 are not in contact with each other.

[0103] The two configurations of the first through hole 211 and the fourth through hole 212 can be configured according to requirements and the matching requirements of the performance between the first speaker 3 and the second speaker 5, which are not limited in the embodiments of the present disclosure.

[0104] In the case where the second sound transmitting member 6 is not in contact with the first sound transmitting member 4, the first through hole 211 and the fourth through hole 212 may be connected to each other or not. When the first through hole 211 and the fourth through hole 212 are connected to each other, the gap between the first sound transmitting member 4 and the second sound transmitting member 6 may be filled with other materials, or no material is used to fill the gap. When the first through hole 211 and the fourth through hole 212 are not connected, the first sound transmitting member 4 and the second sound transmitting member 6 are separated by the foam 21. It can be set according to actual needs, and the embodiment of the present disclosure is not limited to this.

[0105] The technical solution provided by the embodiments of the present disclosure includes at least the following beneficial effects:

[0106] The disclosed embodiment provides a terminal device, wherein the first sound transmitting member 4 is located between the first speaker 3 and the cover plate 22, is penetrated through the first through hole 211, and is respectively connected to the first speaker 3 and the cover plate 22, so that the vibration of the first speaker 3 can be effectively transmitted to the cover plate 22 through the first sound transmitting member 4 to realize sound conduction, thereby avoiding the phenomenon of reduced loudness caused by conduction through the foam 21, improving the loudness of the conducted sound, and improving the sound effect of the terminal device.
