The electronic device provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
As shown in fig. 1, the present application discloses an electronic device including a center frame 100, a sound cavity case 200, and an antenna board 300.
The middle frame 100 includes a ring portion 110, the ring portion 110 may be an exposed portion, the ring portion 110 may surround a display screen of the electronic device, and an outer surface of the ring portion 110 may be an arc surface, and the arc surface may provide a good grip feeling for a user. The middle frame 100 is provided with an accommodating space, the accommodating space can be used for arranging the sound cavity housing 200, the antenna board 300 and other parts of the electronic device, and meanwhile, a contact part is further arranged in the accommodating space, namely, the middle frame 100 is provided with a contact part positioned in the accommodating space, and the contact part can be in contact with the antenna board 300, so that the function of receiving and sending signals by the electronic device is realized, namely, the middle frame 100 can be of a metal structure, so that the middle frame can be used as an antenna of the electronic device.
The sound cavity housing 200 and the antenna plate 300 are both disposed in the accommodating space, the antenna plate 300 is close to the annular portion 110, an antenna spring 301 is disposed on one side of the antenna plate 300, and the antenna spring 301 abuts against the contact portion. The antenna plate 300 is disposed close to the annular portion 110, so that the antenna spring 301 is prevented from being too long, and the reliability of the antenna plate 300 abutting against the contact portion is improved. The length and the width of the antenna board 300 are both greater than the thickness of the antenna board 300, i.e. the thickness of the antenna board 300 is the minimum size of the antenna board 300. The antenna board 300 has a first face 303 and a second face 304, the first face 303 faces the loop portion 110, the second face 304 is a face of the antenna board 300 facing away from the loop portion 110, and the first face 303 and the second face 304 are opposite to each other in a thickness direction of the antenna board 300. That is, the antenna board 300 is disposed in the accommodating space in an upright or inclined manner, and both sides of the antenna board 300 having a larger area face the annular portion 110 and the acoustic cavity case 200, respectively.
In the embodiment of the present application, the antenna board 300 disposed side by side with the sound cavity housing 200 in the prior art is vertically or obliquely disposed in the accommodating space, and the antenna elastic sheet 301 is disposed on one side of the antenna board 300 to abut against the contact portion disposed on the middle frame 100, thereby implementing the reception and transmission of signals of the electronic device. Erect or the space of antenna panel 300 top of slope setting has make full use of, consequently can make full use of the space in the electronic equipment to can avoid the waste of electronic equipment's inner space, and then can improve electronic equipment's space utilization, simultaneously, sound chamber shell 200 can extend towards the direction of antenna panel 300, thereby can make the volume of sound chamber bigger, and then can promote electronic equipment's audio.
In an alternative embodiment, the antenna board 300 has a third surface, the third surface connects the first surface 303 and the second surface 304 of the antenna board 300 and faces the middle frame 100, and the contact portion is disposed corresponding to the third surface. In this case, since the area of the third surface on which the antenna dome 301 is disposed is small, the size of the disposed antenna dome 301 is small, the contact area between the antenna dome 301 and the contact portion is also small, and the function of receiving and transmitting signals of the electronic device is affected. Therefore, in another alternative embodiment, the annular portion 110 is provided with an inner sidewall 111, the inner sidewall 111 is opposite to the antenna board 300, and the contact portion is provided on the inner sidewall 111. In this embodiment, the inner sidewall 111 is opposite to the first surface 303 of the antenna board 300, and the first surface 303 is a surface of the antenna board 300 with a larger available area, where the available area refers to an area of the antenna board 300 where the antenna dome 301 can be disposed. Therefore, the antenna dome 301 with a larger size can be arranged on the first surface 303, and accordingly, the contact area between the contact part and the antenna dome 301 is increased, so that the function of receiving and transmitting signals of the electronic device can be improved.
In another alternative embodiment, the sound cavity housing 200 is disposed separately from the antenna board 300, that is, the sound cavity housing 200 is not connected to the antenna board 300. In this embodiment, an additional connecting member is required to be connected to the antenna board 300, so as to fix the antenna board 300, however, this would increase the number of parts in the electronic device, and the weight of the electronic device would also increase. Therefore, in an alternative embodiment, the sound cavity housing 200 may be connected to the antenna board 300, and thus the sound cavity housing 200 may be connected to the antenna board 300 by its own structure, so as to fix the antenna board 300, and thus, the use of excessive connecting components may be avoided, so as to make the electronic device lighter.
In order to realize the connection between the sound cavity housing 200 and the antenna board 300, fasteners such as screws may be used to fix the antenna board 300 to the side of the sound cavity housing 200, but such a structure may cause the fasteners to occupy the inner space of the sound cavity housing 200, which is not favorable for ensuring the sound effect of the electronic device. Therefore, in a further alternative embodiment, a side of the sound cavity housing 200 facing the annular part 110 is provided with a first protrusion 210, the antenna plate 300 is located between the first protrusion 210 and the annular part 110, the antenna plate 300 is connected to the first protrusion 210, and specifically, the second face 304 of the antenna plate 300 is connected to a face of the first protrusion 210 facing the annular part 110. Since the first protrusion 210 is additionally disposed, the inner space of the sound cavity housing 200 is not occupied, thereby facilitating to improve the sound effect of the electronic device.
However, the above embodiment results in the first protrusion 210 being disposed between the antenna board 300 and the side surface of the sound cavity housing 200, which easily results in a large space formed between the second surface 304 of the antenna board 300 and the side surface of the sound cavity housing 200, and thus cannot be fully utilized, resulting in a low space utilization rate in the electronic device. Therefore, in an alternative embodiment, the middle frame 100 has the first bottom surface 101, the sound cavity housing 200 is fixedly connected to the first bottom surface 101, and the antenna board 300 is located between the first protrusion 210 and the first bottom surface 101, so that a space formed by the second surface 304 of the antenna board 300 and the sound cavity housing 200 can be smaller, and thus the space utilization rate in the electronic device can be improved.
In one embodiment, the antenna board 300 is adhered to the first protrusion 210 by glue. In order to make the antenna dome 301 contact the contact portion reliably, the antenna board 300 needs to be disposed close to the loop portion 110, so that the antenna dome 301 and the contact portion can have a large interaction force. Since the antenna board 300 is adhered to the first protrusion 210 by the adhesive, the adhesive generates a force on the antenna board 300 by adhering to the antenna board 300. Because the external environment and the environment in the electronic device generally have a large influence on the colloid, and the adhesiveness of the colloid is easily reduced, the reaction force of the annular portion 110 on the antenna elastic sheet 301 can cause the antenna plate 300 to gradually get away from the annular portion 110, and the distance between the annular portion 110 and the antenna plate 300 is increased, so that the interaction force between the antenna elastic sheet 301 and the contact portion becomes small, and further the antenna elastic sheet 301 and the contact portion are in poor contact, and the electronic device is influenced to receive and send signals. Therefore, in another embodiment, a first clamping groove 211 is formed on a side of the first protruding portion 210 facing the first bottom surface 101, and one end of the antenna board 300 is clamped in the first clamping groove 211, and further alternatively, the antenna board 300 may be in interference fit with the first clamping groove 211. Because the position of the first card slot 211 cannot be changed, when one end of the antenna board 300 is clamped in the first card slot 211, the acting force applied by the first card slot 211 to the antenna board 300 cannot be changed, so that the reaction force applied to the antenna elastic sheet 301 by the annular part 110 can be overcome, and the antenna elastic sheet 301 and the annular part 110 can be contacted reliably all the time.
In an alternative embodiment, the sound cavity housing 200 includes a housing main body 220 and the aforementioned first protrusion 210, the first protrusion 210 is disposed on the housing main body 220, the housing main body 220 is fixedly connected to the first bottom surface 101, the first protrusion 210 has a first top surface 212 facing away from the first bottom surface 101, the housing main body 220 has a second top surface 221 facing away from the first bottom surface 101, and the first top surface 212 is higher or lower than the second top surface 221. When the first top surface 212 is higher than the second top surface 221, the usable area of the antenna board 300 may be larger, however, the overall height of the sound cavity housing 200 is increased, which also results in an increase in the thickness of the electronic device; when the first top surface 212 is lower than the second top surface 221, due to the limitation of the first protrusion 210, the available area of the antenna board 300 is smaller, and the size of the antenna dome 301 disposed on the antenna board 300 is correspondingly reduced, thereby affecting the performance of receiving and transmitting signals of the electronic device. Therefore, in another alternative embodiment, the first top surface 212 may be flush with the second top surface 221, so that the problem of increasing the thickness of the electronic device may be avoided, and the available area of the antenna board 300 may be increased.
In another alternative embodiment, the antenna board 300 further has a second bottom surface 302 facing away from the first protrusion 210, and the first bottom surface 101 is separated from the second bottom surface 302, that is, a gap is formed between the first bottom surface 101 and the second bottom surface 302, which may increase the thickness of the electronic device and waste the space in the electronic device. Therefore, in an alternative embodiment, the first bottom surface 101 abuts against the second bottom surface 302, that is, the first bottom surface 101 contacts with the second bottom surface 302, and there is no gap between the first bottom surface 101 and the second bottom surface 302, so that space in the electronic device is not wasted, and the thickness of the electronic device is also smaller, and meanwhile, because the first bottom surface 101 contacts with the second bottom surface 302, the middle frame 100 can support the antenna board 300, so that the supporting effect on the antenna board 300 is improved.
In an alternative embodiment, the antenna board 300 is adhered to the middle frame 100 by glue. In order to make the antenna dome 301 contact the contact portion reliably, the antenna board 300 needs to be disposed close to the loop portion 110, so that the antenna dome 301 and the contact portion can have a large interaction force. Since the antenna board 300 is adhered to the middle frame 100 by the adhesive, the adhesive generates a force to the antenna board 300 by adhering to the antenna board 300. Because the environment among external environment and the electronic equipment is great to the influence of colloid, makes the cohesiveness of colloid decline easily, consequently, the loop portion 110 can lead to antenna plate 300 to keep away from loop portion 110 gradually to the reaction force of loop portion 110 to antenna shell fragment 301, increases the distance of loop portion 110 and antenna plate 300 to make the interact power between antenna shell fragment 301 and the contact site diminish, and then lead to antenna shell fragment 301 and the contact site contact failure, influence electronic equipment received signal. Therefore, in another embodiment, the middle frame 100 is provided with a second protrusion 120, the second protrusion 120 is provided with a second clamping groove 121, and one end of the antenna board 300 is clamped in the second clamping groove 121, and further alternatively, the antenna board 300 may be in interference fit with the second clamping groove 121. Because the position of the second card slot 121 is not changed, when one end of the antenna board 300 is clamped in the second card slot 121, the acting force applied to the antenna board 300 by the second card slot 121 is not changed, so that the reaction force applied to the antenna elastic sheet 301 by the annular part 110 can be overcome, and the antenna elastic sheet 301 and the annular part 110 can be contacted reliably all the time.
In a further alternative embodiment, the antenna plate 300 is located between the sound cavity housing 200 and the annular portion 110, and the sound cavity housing 200 and the antenna plate 300 are disposed in close proximity. That is, the second face 304 of the antenna board 300 and the sound cavity cover 200 are in contact with each other, and no gap exists. However, the second surface 304 with a larger area of the antenna board 300 cannot be utilized in the above manner, and therefore, the coaxial line 400 needs to be disposed on a side with a smaller area, which results in a smaller size of the coaxial line 400, and further results in a smaller contact area between the coaxial line 400 and the antenna board 300, which affects the performance of receiving and transmitting signals of the electronic device. Therefore, in another alternative embodiment, the antenna plate 300 is located between the sound cavity housing 200 and the annular portion 110, and the sound cavity housing 200 is spaced from the antenna plate 300, that is, the antenna plate 300 is not disposed in close contact with the sound cavity housing 200, and at the same time, the sound cavity housing 200 has a gap with the antenna plate 300, so that the coaxial line 400 can be disposed on the second face 304 with a larger area on the antenna plate 300, so that the size of the coaxial line 400 can be larger, and the contact area between the coaxial line 400 and the antenna plate 300 is larger, so that the performance of receiving and sending signals by the electronic device can be further improved.
In an alternative embodiment, the direction in which the annular part 110 extends toward the sound cavity housing 200 is a first direction, and the thickness direction of the antenna plate 300 has an included angle smaller than 90 ° with the first direction, that is, the antenna plate 300 is disposed obliquely with respect to the horizontal plane. However, since the antenna board 300 is disposed obliquely, one end of the antenna board 300 is closer to the sound cavity housing 200, so that the extension of the sound cavity housing 200 toward the annular portion 110 is smaller, the volume of the sound cavity is smaller, and more space in the electronic device is wasted. Therefore, in another alternative embodiment, the thickness direction of the antenna plate 300 is parallel to the first direction, that is, the antenna plate 300 is vertically disposed, the antenna plate 300 has less limitation on the sound cavity housing 200, one side of the sound cavity housing 200 can be closer to the annular portion 110, and the volume of the sound cavity can be larger without wasting too much space in the electronic device.
The electronic device disclosed in the embodiment of the present application may be a smart phone, a tablet computer, an electronic book reader, a wearable device (e.g., a smart watch), an electronic game machine, and the like, and the specific kind of the electronic device is not limited in the embodiment of the present application.
