The electromagnetic shielding structure can also block the magnetic field generated by the loudspeaker from affecting the antenna radiator, thus ensuring the radiation intensity of the antenna radiator.

[0022] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0024] Figure 1 This is a schematic diagram of an antenna speaker integrated module according to one embodiment.

[0025] Figure 2 This is a schematic diagram of an antenna speaker integrated module according to one embodiment.

[0026] Figure 3 This is illustrated according to one embodiment. Figure 1 Cross-sectional view along the AA direction.

[0027] Figure 4 It is shown according to another embodiment. Figure 1 Cross-sectional view along the AA direction. Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] In related technologies, loudspeakers and cavity antennas are often placed adjacent to or overlapping each other, which can easily lead to interference between the sound waves emitted by the loudspeaker and the cavity antenna. This not only affects the quality of audio playback but also interferes with the efficiency and quality of the cavity antenna's wireless signal transmission. Furthermore, electromagnetic coupling, for example, between the antenna's magnetic field and the magnetic components inside the loudspeaker can easily cause the loudspeaker to emit abnormal sounds.

[0030] To address the aforementioned technical problems, this disclosure provides an antenna-speaker integrated module and electronic device. The antenna-speaker integrated module includes a housing and a speaker, an antenna radiator, and an electromagnetic shielding structure disposed within the housing. The speaker is disposed in a first cavity of the housing, and the antenna radiator is disposed in a second cavity of the housing. Gas exchange is possible between the first and second cavities. The electromagnetic shielding structure is disposed between the first and second cavities, and is used to block the transmission of electromagnetic signals from the antenna radiator to the speaker, and to block the transmission of electromagnetic signals from the speaker to the antenna radiator. In this disclosure, the speaker and the antenna radiator are separately disposed within the first and second cavities, allowing for gas exchange. This allows the second cavity to serve as an expansion space for the speaker's acoustic cavity, improving the speaker's external sound output. Furthermore, the electromagnetic shielding structure blocks the transmission of electromagnetic signals from the antenna radiator to the speaker, preventing any impact on the speaker's audio playback performance. The electromagnetic shielding structure also blocks the magnetic field generated by the speaker from affecting the antenna radiator, ensuring the radiation intensity of the antenna radiator.

[0031] According to an exemplary embodiment, such as Figure 1As shown, this embodiment provides an antenna-speaker integrated module for use in electronic devices. This module combines the functions of an antenna and a speaker, integrating the speaker and antenna (cavity antenna) to share some physical structures and cavity space, thus reducing the thickness of internal component stacking in electronic devices. For example, the rear acoustic cavity of the speaker and the cavity of the cavity antenna are connected and reused.

[0032] like Figure 1 and Figure 2 As shown, the antenna-speaker integrated module includes a housing 10, a speaker 20, and an antenna radiator 30. The housing 10 defines a first cavity 10a and a second cavity 10b. The speaker 20 is disposed in the first cavity 10a, and the antenna radiator 30 is disposed in the second cavity 10b. See also [reference needed] for one example. Figure 2 The speaker 20 is disposed in the first cavity 10a, and the antenna radiator 30 is disposed on the outer wall of the second cavity 10b. Thus, the second cavity 10b can separate the rear acoustic cavity of the speaker 20 from the antenna radiator 30 to avoid the electrical signal radiated by the antenna radiator 30 from interfering with the speaker 20.

[0033] like Figures 2 to 4 As shown, the antenna-speaker integrated module also includes an electromagnetic shielding structure 40. The electromagnetic shielding structure 40 can block the transmission of electrical signals radiated by the antenna radiator 30 to the speaker 20, causing the speaker 20 to convert the electrical signals into audible noise. The electromagnetic shielding structure 40 can also block the magnetic field generated by the speaker 20 during operation, preventing the magnetic field from interfering with the antenna radiator 30 and causing a reduction in communication quality.

[0034] The electromagnetic shielding structure 40 is made of conductive materials, including but not limited to metals, alloys (such as stainless steel), and composite materials (such as conductive foam).

[0035] Among them, see Figure 2 Gas exchange is possible between the first cavity 10a and the second cavity 10b. In some embodiments, see [reference needed]. Figure 2 The electromagnetic shielding structure 40 includes a ventilation structure 40a, through which the first cavity 10a and the second cavity 10b can be connected. This allows the second cavity 10b to expand the acoustic cavity of the speaker 20, resulting in a larger acoustic cavity and improved external sound output from the speaker 20. In some embodiments, a mounting gap exists between the electromagnetic shielding structure 40 and the inner wall of the housing, allowing gas exchange between the first and second cavities. In still other embodiments (not shown in the figures), a pipe is provided between the first and second cavities for gas exchange.

[0036] Furthermore, the electromagnetic shielding structure positioned between the first and second cavities can block electromagnetic signals. For example, the electromagnetic shielding structure can prevent electromagnetic signals emitted by the antenna radiator in the second cavity from being transmitted to the first cavity, thus avoiding the audio playback effect of the speaker being affected by electromagnetic signals. Additionally, the electromagnetic shielding structure can also prevent the magnetic field generated by the speaker from interfering with the antenna radiator, thereby ensuring the radiation intensity of the antenna radiator.

[0037] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides an antenna-speaker integrated module. The antenna-speaker integrated module includes a housing 10 and a speaker 20, an antenna radiator 30, and an electromagnetic shielding structure 40 disposed in the housing 10. The speaker 20 is disposed in the first cavity 10a of the housing 10, the antenna radiator 30 is disposed in the second cavity 10b of the housing 10, and the electromagnetic shielding structure 40 is disposed between the first cavity 10a and the second cavity 10b. The electromagnetic shielding structure 40 is used to block the transmission of electrical signals from the antenna radiator 30 to the speaker 20.

[0038] In this embodiment, as Figure 2 As shown, the electromagnetic shielding structure 40 includes a shielding structure body and a ventilation structure 40a disposed in the shielding structure body. The first cavity 10a and the second cavity 10b can exchange gases through the ventilation structure 40a.

[0039] In some embodiments, the ventilation structure can be an air gap defined by the shielding structure body and the housing 10. See also Figure 2 The shielding structure includes multiple shielding components 41, which are arranged in an alternating manner. The air gaps formed between adjacent shielding components 41 and between shielding components 41 and the shell 10 constitute a ventilation structure 40a.

[0040] The size and placement of the shielding element 41 can be controlled to adaptively adjust the size of the ventilation structure 40a. In one example, along the arrangement direction of the first cavity 10a and the second cavity 10b ( Figure 1 (as shown in the x-direction), the size of the shield 41 can be set to 2-3mm, and the spacing between adjacent shields 41 can be set to 2-3mm, along the width direction of the housing 10 (as shown in the x-direction). Figure 1 (as shown in the y-direction), the gap between the shielding components 41 can be set to 3-5mm.

[0041] In one example, such as Figure 2 and Figure 3As shown, the shielding element 41 is conductive foam. Conductive foam is a material obtained by wrapping conductive parts on flame-retardant sponge and undergoing a series of treatments. Conductive foam has good surface conductivity and can effectively shield electromagnetic signals. In this embodiment, multiple shielding elements 41 are spaced apart to form a ventilation structure 40a between adjacent shielding elements 41 for gas exchange. This avoids damaging the integrity of the conductive fabric by drilling holes (forming a ventilation structure) on the surface of the conductive foam.

[0042] Among them, such as Figure 1 As shown, the antenna speaker integrated module includes a porous structure 70, which is disposed within the second cavity 10b. The porous structure 70 has a sound absorption and volume expansion effect, so as to maintain the acoustic cavity volume while absorbing the vibration sound waves of the speaker 20, thus ensuring the external sound output of the speaker 20. In one example, the porous structure 70 can be zeolite, which, as an insulator, can also avoid affecting the signal of the antenna radiator 30.

[0043] Among them, such as Figure 1 As shown, the antenna speaker integration module also includes a first partition mesh 50, which is disposed between the electromagnetic shielding structure 40 and the porous structure 70. The first partition mesh 50 is used to limit the porous structure 70 to prevent it from shaking inside the housing 10 and to prevent it from blocking the ventilation structure 40a, causing vibration when in contact with the operating speaker 20. In one example, the first partition mesh 50 can be an injection-molded mesh, which is connected to the housing 10 by integral injection molding, bonding, or welding.

[0044] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides an antenna-speaker integrated module. The antenna-speaker integrated module includes a housing 10 and a speaker 20, an antenna radiator 30, and an electromagnetic shielding structure 40 disposed in the housing 10. The speaker 20 is disposed in the first cavity 10a of the housing 10, the antenna radiator 30 is disposed in the second cavity 10b of the housing 10, and the electromagnetic shielding structure 40 is disposed between the first cavity 10a and the second cavity 10b. The electromagnetic shielding structure 40 is used to block the transmission of electrical signals from the antenna radiator 30 to the speaker 20.

[0045] In this embodiment, as Figure 4As shown, the electromagnetic shielding structure 40 includes a metal mesh 42 as its main shielding structure, with mesh holes forming a ventilation structure. In this embodiment, the metal portion of the metal mesh 42 can block electromagnetic signals, and the mesh holes also allow for gas exchange between the first cavity 10a and the second cavity 10b, enabling the second cavity to serve as an expansion space for the speaker's acoustic chamber and improving the speaker's external sound output. The metal mesh 42 can be formed, for example, by etching multiple mesh holes onto a metal plate using an etching process.

[0046] Among them, see Figure 3 and Figure 4 The antenna speaker integrated module provided in this embodiment includes a porous structure 70, which is disposed within the second cavity 10b. The size of the mesh holes of the metal separator 42 is smaller than the size of the porous structure 70 to limit the movement of the porous structure 70. In one example, the mesh holes of the metal separator 42 are circular holes with a diameter of approximately 0.1 mm.

[0047] In one exemplary embodiment, such as Figure 1 As shown, this embodiment provides an antenna-speaker integrated module. The antenna-speaker integrated module includes a housing 10 and a speaker 20, an antenna radiator 30, and an electromagnetic shielding structure 40 disposed in the housing 10. The speaker 20 is disposed in the first cavity 10a of the housing 10, the antenna radiator 30 is disposed in the second cavity 10b of the housing 10, and the electromagnetic shielding structure 40 is disposed between the first cavity 10a and the second cavity 10b. The electromagnetic shielding structure 40 is used to block the transmission of electrical signals from the antenna radiator 30 to the speaker 20.

[0048] The antenna speaker integrated module provided in this embodiment may include various structures and components of the antenna speaker integrated module provided in any of the foregoing embodiments.

[0049] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the housing 10 of the antenna speaker integrated module includes a first metal plate 11 and a second metal plate 12 disposed opposite to each other, along the vibration direction of the speaker 20 ( Figure 1 As shown in the z-direction, the first metal plate 11 and the second metal plate 12 are respectively disposed on both sides of the speaker 20. During the operation and vibration of the speaker 20, the first metal plate 11 and the second metal plate 12 have high structural strength and are not easily deformed, thereby avoiding changes in the acoustic cavity volume that would lead to poor external sound output, and avoiding the shape of the antenna radiator 30 being affected by deformation of the housing 10. In one example, the thickness of the first metal plate 11 and the second metal plate 12 is approximately 0.2 mm.

[0050] See Figure 1 , Figure 3 and Figure 4 The antenna radiator 30 is disposed on the side of the first metal plate 11 and the second metal plate 12 that is opposite to the second cavity 10b. That is, the antenna radiator 30 is disposed on the outer wall of the second cavity 10b. The first metal plate 11, the second metal plate 12 and the electromagnetic shielding structure 40 form a shield to prevent the sound waves generated by the speaker 20 from affecting the antenna radiator 30. It can also prevent the antenna signal generated by the antenna radiator 30 from interfering with the speaker 20, so that the antenna speaker integrated module can take into account both good audio playback performance and wireless communication performance.

[0051] Among them, such as Figure 3 and Figure 4 As shown, a portion of the structure of the first metal plate 11 or the second metal plate 12 is recessed into the housing 10 to form a protruding structure 10c within the housing 10, and the electromagnetic shielding structure 40 is disposed at the protruding structure 10c. In some alternative embodiments, see [reference needed]. Figure 3 and Figure 4 Both the first metal plate 11 and the second metal plate 12 have raised structures 10c. In this embodiment, by setting the raised structures 10c on the first metal plate 11 and the second metal plate 12 and setting the electromagnetic shielding structure 40 at the raised structures 10c, the material used for the electromagnetic shielding structure 40 can be reduced to lower the cost, and the installation of the electromagnetic shielding structure 40 in a designated position can be facilitated to improve product consistency.

[0052] Among them, see Figures 1 to 4 The housing 10 also includes an insulating support 13, which connects a first metal plate 11 and a second metal plate 12 disposed opposite to each other. In one example, the housing 10 is cuboid in shape, with the first metal plate 11 and the second metal plate 12 serving as the top and bottom walls of the cuboid, respectively, and the insulating support 13 forming the four side walls of the cuboid. The insulating support 13 may be made of materials such as plastic or fiber composite materials. Plastic and fiber composite materials can be injection molded, which facilitates complex structural designs and optimizes the acoustic performance of the loudspeaker while ensuring structural strength.

[0053] Among them, such as Figure 1 As shown, at least one of the first metal plate 11, the second metal plate 12, and the insulating support 13 is provided with a pressure equalization channel (filled by a second partition mesh 60), and the second partition mesh 60 is provided at the pressure equalization channel. The second partition mesh 60 can be a mesh structure with micro-ventilation holes, which can achieve pressure balance between the second cavity 10b and the external environment, and also prevent dust and liquid from the external environment from entering the second cavity 10b. In some optional embodiments, when manufacturing and maintaining the antenna speaker integrated module, a porous structure 70 can also be filled into the second cavity through the pressure equalization channel.
