Description

TECHNICAL FIELD

[0001] The utility model relates to electronic equipment technical field, concretely relates to a kind of antenna and sounder integrated device and electronic equipment. BACKGROUND

[0002] With the popularity of mobile phones, tablets and other electronic devices, thin and light has become the mainstream trend of the market. This trend puts higher requirements on the internal structure design of electronic devices. As an important component of electronic devices, the sounder needs to have a large back cavity to create deep and shocking sound effects in order to improve the immersion and auditory experience of users in scenarios such as video entertainment and gaming, but this often means that the sounder will be relatively large in size. At the same time, the cavity antenna, as a widely used high-performance antenna solution in electronic devices, its key performance indicators such as radiation efficiency, directivity and operating bandwidth also depend on specific physical dimensions and structural design. In order to ensure that the antenna performance meets the growing communication needs, electronic devices must reserve sufficient space resources for it. In the case of extremely limited internal space, the space requirements of the sounder and the cavity antenna form a clear competitive relationship. This space competition not only increases the complexity of internal component layout, but also directly restricts the possibility of electronic devices developing towards thinner and more compact.

[0003] Accordingly, there is a need in the art for a new technical solution to solve the above problems. SUMMARY

[0004] In order to solve at least one of the above problems in the prior art, i.e. to solve the problem that the space requirements of the existing sounder and antenna affect the development of thin and light electronic devices. Based on this, the present application provides an antenna and sounder integrated device, which comprises:

[0005] an antenna module and a sounder module;

[0006] a device body, a first cavity and a second cavity are formed in the device body, the sounder module is arranged in the first cavity, and the diaphragm of the sounder module divides the first cavity into a front cavity and a back cavity; the front cavity is in communication with the sound outlet on the device body, and the back cavity is in communication with the second cavity; the antenna module is arranged in the second cavity, and the corresponding device body is configured to support the antenna module to receive and emit electromagnetic waves.

[0007] In the preferred technical scheme of the sound generator and antenna integrated device, the device body corresponding to the second cavity comprises a first side plate and a second side plate arranged oppositely, the first side plate comprises radiation areas and reflection areas arranged alternately from the first cavity to the second cavity, the first side plate corresponding to the radiation area is configured to support the antenna module to receive and emit electromagnetic waves, and the inner wall of the first side plate corresponding to the reflection area and the inner wall of the second side plate are both configured to reflect electromagnetic waves.

[0008] In the preferred technical scheme of the sound generator and antenna integrated device, the first side plate corresponding to the radiation area is made of a non-metal material.

[0009] In the preferred technical scheme of the sound generator and antenna integrated device, the first side plate corresponding to the reflection area and / or the second side plate are made of a metal material; or

[0010] The inner wall of the first side plate corresponding to the reflection area and / or the inner wall of the second side plate are both provided with a metal layer.

[0011] In the preferred technical scheme of the sound generator and antenna integrated device, the second cavity is filled with a medium material.

[0012] In the preferred technical scheme of the sound generator and antenna integrated device, the medium material is a liquid, a porous material or high-pressure air.

[0013] In the preferred technical scheme of the sound generator and antenna integrated device, a blocking piece is arranged at the communication position of the rear cavity and the second cavity;

[0014] When the medium material is a porous material, the blocking piece is configured to block the medium material from entering the first cavity while allowing air and sound waves to enter the second cavity;

[0015] When the medium material is a liquid or high-pressure air, the blocking piece is configured to block the medium material from entering the first cavity while allowing sound waves to enter the second cavity.

[0016] In the preferred technical scheme of the sound generator and antenna integrated device, the device body corresponding to the first cavity and the device body corresponding to the second cavity are connected through a sealing material; or

[0017] The device body corresponding to the first cavity and the device body corresponding to the second cavity are integrally formed.

[0018] In the preferred technical scheme of the sound generator and antenna integrated device, the antenna module is a single-feed antenna module or a multi-feed antenna module.

[0019] This application also provides an electronic device, which includes the speaker and antenna integrated device described in the preferred embodiment above.

[0020] Those skilled in the art will understand that the integrated transmitter and antenna device of this invention, by placing a transmitter module in a first cavity and an antenna module in a second cavity within the device body, and using a diaphragm to divide the first cavity into a front cavity and a rear cavity, while simultaneously connecting the rear cavity to the second cavity, allows the integrated device to not only possess the excellent characteristics of a cavity antenna, but also reduce the spatial dependence of the transmitter module on the first cavity by expanding the space of the rear cavity. This allows the transmitter module to improve the low-frequency performance of the integrated device without occupying a large space. Furthermore, by integrating the transmitter and antenna into one unit, this application significantly reduces the space required for each component in the prior art, facilitating the development of thinner and lighter electronic devices and solving the problem that the separate space requirements of existing transmitters and antennas hinder the development of thinner and lighter electronic devices.

[0021] Furthermore, by setting the first side plate and the second side plate opposite to each other, and alternately setting the radiation area and the reflection area on the first side plate, the radiation area can support the antenna module to receive and transmit electromagnetic waves, and the reflection area and the inner wall of the second side plate can reflect electromagnetic waves, making the electromagnetic waves more directional, and causing a more focused radiation beam to be formed between the first side plate and the second side plate, thereby enhancing the signal transmission and reception capabilities of the integrated device.

[0022] Furthermore, by filling the second cavity with a dielectric material, not only is the virtual space of the rear cavity further expanded, thereby significantly improving the low-frequency performance of the integrated device, but the propagation speed and phase of electromagnetic waves can also be effectively controlled, further enhancing the interference effect of electromagnetic waves.

[0023] Furthermore, when the dielectric material is porous, it can absorb some of the air in the second cavity, allowing some air to enter the second cavity after the diaphragm vibrates and compresses the air inside, thereby improving the low-frequency performance of the integrated device. When the porous material is liquid or high-pressure air, the liquid and high-pressure air can absorb some of the sound wave energy in the low-frequency range, which helps to optimize the audio performance of the integrated device in the low-frequency range.

Detailed Implementation

[0033] Preferred embodiments of this application will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

[0034] It should be noted that in the description of this application, the terms "upper", "lower", "inner", "top", "bottom", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and is not intended to indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0035] Furthermore, it should be noted that, in the description of this application, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0036] like Figures 1-3 As shown, to address the issue of the space constraints of separate transmitters and antennas hindering the development of thinner and lighter electronic devices, the transmitter and antenna integrated device of this application includes an antenna module 3, a transmitter module 2, and a device body 1. The device body 1 contains a first cavity 111 and a second cavity 121. The transmitter module 2 is housed within the first cavity 111, and the diaphragm 21 of the transmitter module 2 divides the first cavity 111 into a front cavity 1111 and a rear cavity 1112. The front cavity 1111 communicates with the sound outlet 112 on the device body 1, and the rear cavity 1112 communicates with the second cavity 121. The antenna module 3 is housed within the second cavity 121, and the corresponding device body 1 is configured to support the antenna module 3 in receiving and transmitting electromagnetic waves.

[0037] During operation, the electromagnetic wave frequency generated by the speaker module 2 ranges from 20Hz to 20kHz. The electromagnetic wave frequency range generated by the antenna module 3 ranges from 300kHz to 300GHz. The speaker module 2 and antenna module 3 operate at significantly different frequency bands, thus allowing them to operate independently without interference.

[0038] This application integrates a transmitter module 2 within a first cavity 111 of the device body 1 and an antenna module 3 within a second cavity 121. A diaphragm 21 divides the first cavity 111 into a front cavity 1111 and a rear cavity 1112, while simultaneously connecting the rear cavity 1112 to the second cavity 121. This allows the integrated device to not only possess the excellent characteristics of a cavity antenna but also reduce the spatial dependence of the transmitter module on the first cavity 111 by expanding the space of the rear cavity 1112. This enables the transmitter module 2 to improve the low-frequency performance of the integrated device without occupying a large space. Furthermore, by integrating the transmitter and antenna into one unit, this application significantly reduces the space required for each component in existing technologies, facilitating the development of thinner and lighter electronic devices and solving the problem that the separate space requirements of existing transmitters and antennas hinder the development of thinner and lighter electronic devices.

[0039] The following is further reference Figures 1-6 This paper describes a preferred embodiment of the transmitter and antenna integrated device of this application. Those skilled in the art will understand that the embodiments described below are merely illustrative of the principles of this application and are not intended to limit the scope of protection of this application. Provided that the transmitter and antenna integrated device at least includes an antenna module 3, a transmitter module 2, and a device body 1, those skilled in the art can adjust the following configuration to make this application applicable to more specific application scenarios.

[0040] See Figure 1The device body 1 includes a first body 11 and a second body 12. The first body 11 has a first accommodating space, and the second body 12 has a second accommodating space. The first body 11 and the second body 12 are connected by a sealing material to form a first cavity 111 and a second cavity 121. A sound generator module 2 is disposed in the first cavity 111. A sound outlet 112 communicating with the first cavity 111 is opened at the bottom of the first body 11, so that the sound generated by the sound generator module 2 can be output to the outside through the sound outlet 112.

[0041] It should be noted that this application does not limit the specific material of the sealing material, as long as the first body 11 and the second body 12 can be sealed together. For example, the sealing material can be sealing foam 13. Furthermore, this application does not limit the shape of the first body 11 and the second body 12, as long as the connection between the first body 11 and the second body 12 can form a first cavity 111 and a second cavity 121. For example, both the first body 11 and the second body 12 can be rectangular, trapezoidal, etc. Figure 1 and Figure 3 As shown, when both the first body 11 and the second body 12 are trapezoidal, the connection between the first body 11 and the second body 12 is inclined. Compared with the first body 11 and the second body 12 being rectangular, this can increase the contact area between the first body 11 and the second body 12, thereby improving the connection strength between the first body 11 and the second body 12.

[0042] In the exemplary embodiments, the specific configuration of the device body 1 is not fixed and can be adjusted as needed by those skilled in the art. For example, the first body 11 and the second body 12 can also be integrally formed, such as... Figure 2 As shown. Furthermore, the location of the sound outlet 112 is not fixed in this application, and those skilled in the art can adjust it as needed. For example, the sound outlet 112 can also be located on the top, front, rear, and right side of the first body 11.

[0043] See next Figure 1 The sound generator module 2 includes a diaphragm 21, a voice coil 22, and a magnetic circuit system. The diaphragm 21 includes a dome 211 and a surround 212, with the dome 211 extending from the first cavity 111 towards the second cavity 121 (e.g., ...). Figure 1 Extending in the X direction (as shown), a folded ring 212 is arranged around the dome 211. One end of the folded ring 212 is connected to the inner wall of the first cavity 111, and the other end is connected to the diaphragm 21, thereby causing the diaphragm 21 to divide the first cavity 111 into a front cavity 1111 and a rear cavity 1112. The front cavity 1111 and the rear cavity 1112 extend from the bottom to the top of the first body 11 (as shown in the X direction). Figure 1(As shown in the Y direction) are arranged sequentially. The front cavity 1111 is connected to the sound outlet 112. The rear cavity 1112 is equipped with a voice coil 22 and a magnetic circuit system. The magnetic circuit system has a magnetic gap 25. One end of the voice coil 22 is connected to the dome 211, and the other end extends into the magnetic gap 25. This allows the magnetic field generated by the voice coil 22 after it is energized to interact with the magnetic field generated by the magnetic circuit system. This interaction enables the voice coil 22 to move within the magnetic gap 25 and drive the diaphragm 21 to vibrate and produce sound.

[0044] Among them, such as Figure 1 and 4 As shown, the magnetic circuit system includes a central magnet 23 and four side magnets 24 surrounding the central magnet 23. Both the central magnet 23 and the side magnets 24 are disposed on the top inner wall of the first body 11. The four side magnets 24 are spaced apart around the central magnet 23, and a magnetic gap 25 is formed between the outer wall of the central magnet 23 and the inner wall of the side magnets 24. The rear cavity 1112 and the second cavity 121 are connected through the gap 241 between adjacent side magnets 24, thereby expanding the volume of the rear cavity 1112 and improving the low-frequency performance of the transmitter. The device body 1 also includes a partition 14. One end of the partition 14 is connected to the end of the side magnet 24 near the sound outlet 112, and the other end is connected to the bottom inner wall of the first body 11, thereby forming the first cavity 111 and the second cavity 121 on the device body 1. The end of the folded ring 212 away from the dome 211 is connected to the partition 14, thereby dividing the first cavity 111 into a front cavity 1111 and a rear cavity 1112.

[0045] In the exemplary embodiments, the specific configuration of the magnetic circuit system is not fixed and can be adjusted as needed by those skilled in the art. For example, the magnetic circuit system may also include a central magnet 23 and a side magnet 24, the side magnet 24 being a ring structure and surrounding the central magnet 23 to form a magnetic gap 25. When the magnetic circuit system includes a side magnet 24, a hole can be made in the partition corresponding to the rear cavity 1112 to achieve communication between the rear cavity 1112 and the second cavity 121. In addition, it should be noted that when the sound outlet 112 is located on the front, rear, and right sides of the first body 11, the location of the sound outlet 112 corresponds to the front cavity 1111. When the sound outlet 112 is located on the top of the first body 11, the positional relationship between the front cavity 1111 and the rear cavity 1112 also needs to be adjusted accordingly, that is, the front cavity 1111 and the rear cavity 1112 are arranged sequentially from the top to the bottom of the first body 11.

[0046] In the exemplary embodiments, the method of forming the first cavity 111 and the second cavity 121 on the device body 1 is not fixed and can be adjusted as needed by those skilled in the art. For example, the side magnet 24 does not serve as a separator between the first and second accommodating spaces, but is separated only by a partition. That is, the two ends of the partition are connected to the top and bottom of the first body 11 or the second body 12, respectively, so that the first cavity 111 and the second cavity 121 can be formed inside the device body 1. In this case, the end of the folded ring 212 away from the dome 211 is connected to the partition, and a hole communicating with the second cavity is opened on the partition at the position corresponding to the rear cavity 1112.

[0047] See next Figure 1 The device body 1 corresponding to the second cavity 121, namely the second body 12, includes a first side plate 1211 and a second side plate 1212. The first side plate 1211 is located at the top of the second body 12, and the second side plate 1212 is located at the bottom of the second body 12, and the two are arranged opposite to each other. The first side plate 1211 includes a radiating area 12111 and a reflecting area 12112 arranged alternately from the first cavity 111 to the second cavity 121. An antenna module 3 is provided on the inner wall of the second side plate 1212. The antenna module 3 is a single-feed antenna module, and the single-feed antenna module and the sound outlet 112 are located on the same side of the device body 1. The first side plate 1211 corresponding to the radiating area 1211 is made of a non-metallic material, so that the first side plate 1211 corresponding to the radiating area 12111 can support the single-feed antenna module to receive and transmit electromagnetic waves. The first side plate 1211 and the second side plate 1212 corresponding to the reflective area 12112 are both made of metal, which allows the second side plate 1212 and the first side plate 1211 corresponding to the reflective area 12112 to reflect electromagnetic waves. This facilitates the reflection of electromagnetic waves emitted by the single-feed antenna module between the second side plate 1212 and the reflective area 12112, making the electromagnetic waves more directional and causing the first side plate 1211 and the second side plate 1212 to form a more focused radiation beam, thereby enhancing the signal transmission and reception capabilities of the integrated device.

[0048] The reflection and radiation patterns of the single-feed antenna module within the second cavity 121 are shown in the figure. Figure 5 The radiation zone 12111 supporting the antenna module 3 in receiving and transmitting electromagnetic waves means that when the antenna module 3 transmits electromagnetic waves, the electromagnetic waves can propagate outward from the second cavity 121 through the radiation zone 1211; simultaneously, when the antenna module 3 receives electromagnetic waves, the electromagnetic waves can enter the second cavity 121 through the radiation zone 12111 and be received by the antenna module 3. It should be noted that the non-metallic material of the first side plate 1211 corresponding to the radiation zone 1211 in this application is not limited, as long as it can support the antenna module 3 in receiving and transmitting electromagnetic waves. For example, the non-metallic material can be plastic.

[0049] In the exemplary embodiments, the materials of the first side plate 1211 and the second side plate 1212 are not fixed in this application, and those skilled in the art can adjust them as needed. For example, the overall material of the first side plate 1211 is a non-metallic material, and a plurality of first metal layers 12113 are provided on the inner wall of the first side plate 1211 at intervals along the direction from the first cavity 111 to the second cavity 121. The first metal layers 12113 serve as reflective areas 12112, which reflect electromagnetic waves. The area between adjacent first metal layers 12113 serves as a radiating area 12111, which supports the single-feed antenna module in receiving and transmitting electromagnetic waves. Figure 2 As shown. And / or, the material of the second side plate 1212 can also be a non-metallic material, and a second metal layer 12121 can be provided on the inner wall of the second side plate 1212. This second metal layer 12121 can also reflect electromagnetic waves, such as... Figure 2 As shown.

[0050] In the exemplary embodiments, the specific configuration of the antenna module 3 is not fixed and can be adjusted as needed by those skilled in the art. For example, the antenna module 3 can also be a multi-feed antenna module. When the multi-feed antenna module is a dual-feed antenna module, the reflection and radiation patterns within the second cavity 121 are shown below. Figure 6 .

[0051] In the exemplary embodiments, the specific positions of the first side plate 1211 and the second side plate 1212 are not fixed in this application, and those skilled in the art can adjust them as needed. For example, the first side plate 1211 can also be located at the bottom of the second body 12, and the second side plate 1212 can be located at the top of the second body 12. In this case, the magnetic circuit system and the antenna module 3 are located on the same side of the device body 1. Figure 3 As shown. Alternatively, the first side plate 1211 can be located at the front end of the second body 12, and the second side plate 1212 can be located at the rear end of the second body 12. Alternatively, the first side plate 1211 can be located at the left end of the second body 12, and the second side plate 1212 can be located at the right end of the second body 12, as long as the first side plate 1211 is provided with a radiating area 12111 and a reflecting area 12112 at intervals, and the antenna module 3 is provided on the second side plate 1212.

[0052] In an exemplary embodiment, the first body 11 and the second body 12 can be made of the same or different materials. When the first body 11 and the second body 12 are made of the same material, both the first body 11 and the second body 12 can be made of non-metallic materials. In this case, the first body 11 and the second body 12 can be integrally formed or connected by a sealing material. At the same time, a first metal layer 12113 can be provided in the reflective area 12112 of the first side plate 1211, and a second metal layer 12121 can be provided on the inner wall of the second side plate 1212. Alternatively, the first body 11 and the second body 12 can also be made of non-metallic materials. In this case, the first body 11 and the second body 12 can be integrally formed or connected by a sealing material. At the same time, multiple spaced holes can be formed on the first side plate 1211, and non-metallic materials can be provided at the holes to form a radiation area 12111. When the materials of the first body 11 and the second body 12 are different, such as the first body 11 being made of metal and the second body 12 being made of non-metal, the first body 11 and the second body 12 can be connected by a sealing material. At the same time, a first metal layer 12113 can be provided in the reflective area 12112 of the first side plate 1211 in the second body 12, and a second metal layer 12121 can be provided on the inner wall of the second side plate 1212.

[0053] See next Figure 1 The second cavity 121 is filled with a dielectric material, namely Bass powder. Bass powder is a porous material, which can alter the propagation speed and phase of electromagnetic waves, further enhancing the interference effect. It also increases the virtual space of the rear cavity 1112, thereby further improving the low-frequency performance of the transmitter. To prevent Bass powder from entering the rear cavity 1112 through the gap 241 between adjacent side magnets 24, a blocking element is provided at the gap 241. This blocking element is a waterproof, breathable, and sound-permeable membrane 242. This membrane can prevent Bass powder from entering the first cavity 111 while allowing air and sound waves to enter the second cavity 121. This allows the Bass powder to absorb some low-frequency sound waves, optimizing the low-frequency audio performance of the integrated device. It can also absorb some air within the second cavity 121, allowing some air to enter the second cavity 121 when the diaphragm 21 vibrates and compresses the air in the rear cavity 1112, thus improving the low-frequency performance of the integrated device.

[0054] In exemplary embodiments, the specific material of the dielectric material is not fixed, as long as the dielectric material can increase the interference effect and low-frequency performance of the integrated device. For example, the dielectric material can also be other porous materials, liquids, or high-pressure air. High-pressure air refers to air with a density higher than that at atmospheric pressure. It should be noted that when the dielectric material is a liquid or high-pressure air, the liquid and high-pressure air can absorb some of the low-frequency sound waves, optimizing the acoustic performance of the integrated device in the low-frequency range. In this case, the blocking component can be a waterproof and sound-permeable membrane.
