Voice recorders, as one such electronic product capable of recording audio, are widely loved by users in both work and daily life.

[0003] Traditional recording equipment casings are mostly made of plastic, offering advantages such as wear resistance and shock resistance. However, to further enhance the appearance and quality of recording equipment, metal casings are sometimes chosen. However, metal casings can lead to unstable antenna signals inside the recording equipment. Utility Model Content

[0004] This application provides a recording device and a cassette player to solve the problem of unstable antenna signals caused by the metal casing in related technologies.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] In a first aspect, this application provides a recording device, including a metal housing, a circuit board and an antenna module, wherein the metal housing surrounds a receiving cavity for accommodating the circuit board;

[0007] The circuit board has opposite mounting and non-mounting surfaces. The mounting surface is used to mount the antenna module, and the antenna module is electrically connected to the circuit board.

[0008] The circuit board has connected regions, and the positions of the connected regions correspond to the antenna module.

[0009] An insulating component is embedded in the metal housing opposite to the non-mounting plate surface. The insulating component is positioned corresponding to the connecting area, and the insulating component and the connecting area can form a transmission path for the signal transmitted by the antenna module.

[0010] In some embodiments of this application, the projection of the connecting region toward the second housing is located within the insulating element.

[0011] In some embodiments of this application, a mode switch and a recording switch are installed in the first housing, the mode switch and the recording switch are spaced apart, and the mode switch and the recording switch are located on one side of the center line in the length direction of the first housing.

[0012] In some embodiments of this application, the recording device is configured as a recording card.

[0013] In some embodiments of this application, the length of the insulating element is greater than or equal to 15 mm and less than or equal to 25 mm;

[0014] And / or, the width of the insulating element is greater than or equal to 3 mm and less than or equal to 7 mm.

[0019] And / or, there is a second difference between the width of the connected region and the width of the antenna body, the second difference being less than or equal to 0.5 mm.

[0020] In some embodiments of this application, the insulating element is made of one of plastic, ceramic, or glass.

[0021] Secondly, this application provides a card pack, including:

[0022] Base; equipped with magnetic attraction elements,

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0044] In related technologies, the casing of a recording device is typically made of metal. This reduces noise, improves the overall heat dissipation of the recording device, and enhances its appearance.

[0045] However, metals, as good conductors, can interact with electromagnetic waves.

[0046] For example, when an electromagnetic wave encounters a metal casing, the free electrons in the metal will move in a directed manner under the influence of an alternating electric field, forming an induced current. The induced current will generate an electromagnetic field in the opposite direction to the magnetic field of the incident electromagnetic wave. The two will cancel each other out, causing most of the incident electromagnetic wave to be unable to penetrate the metal casing and reach the internal antenna (receiving end). At the same time, the electromagnetic waves emitted by the antenna will also be unable to penetrate the metal casing and radiate outward (transmitting end).

[0047] The metal casing can also generate eddy currents in alternating electromagnetic fields, which convert the energy of electromagnetic waves into heat energy and cause the antenna's radiation efficiency to decrease, and the signal strength and stability to be weakened.

[0048] In other words, the electromagnetic shielding effect of metal absorbs and weakens a certain amount of signal energy. Furthermore, the reflection of electromagnetic waves by metal can disrupt the signal transmission path and potentially generate eddy currents that convert electromagnetic wave energy into heat. An antenna module is mounted on a circuit board inside the metal casing. The signal emitted by the antenna module is weakened and reflected by the metal casing, resulting in signal instability.

[0049] Furthermore, circuit boards have opposing mounting and non-mounting sides. The mounting side is used to mount electronic components (such as processors, capacitors, inductors, resistors, and batteries), while the non-mounting side does not mount electronic components. Single-sided mounting reduces the cost and manufacturing complexity of the circuit board. However, circuit boards typically have conductive layers (such as copper plating), which can shield and absorb signals, leading to signal instability in the antenna module.

[0050] To overcome the deficiencies in related technologies, this application provides a recording device. A metal casing surrounds a cavity for accommodating a circuit board. An antenna module is mounted on the mounting surface of the circuit board, and the antenna module is electrically connected to the circuit board. A connecting area on the circuit board corresponding to the antenna module's location prevents the circuit board from obstructing signals, providing a transmission channel for signal transmission. Furthermore, an insulating component is embedded in the portion of the metal casing opposite the non-mounting surface of the circuit board. The insulation of this component allows the signal emitted by the antenna module to be transmitted to the outside of the metal casing. The signal emitted by the antenna module can pass through the path formed by the connecting area and the insulating component, thus avoiding reflection and absorption of the emitted signal by the metal casing, thereby solving the problem of signal instability or poor quality. Simultaneously, this design ensures good heat dissipation and an aesthetically pleasing appearance for the metal casing.

[0051] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0052] Reference Figure 1 and Figure 2 As shown in the illustration, this application provides a recording device 010 for recording sound and converting it into electrical signals. The recording device 010 can be configured as a recording card, which can perform functions such as recording, transcription, translation, and intelligent summarization. The recording card can be magnetically attached to the back of portable devices such as mobile phones, eliminating the need to carry a separate voice recorder and thus making the recording card portable.

[0053] The recording device 010 includes a metal housing 110. The metal housing 110 protects the internal electronic components from damage caused by physical damage, dust, moisture, or other factors.

[0054] The metal casing 110 can be made of metal to improve its appearance and strength. For example, the metal casing 110 can be made of aluminum alloy.

[0055] The metal housing 110 is surrounded by a receiving cavity 113, which is used to receive the electronic components of the recording device 010.

[0056] The metal housing 110 includes a first housing 111 and a second housing 112, which are connected by fasteners such as bolts. The first housing 111 and the second housing 112 enclose a receiving cavity 113. This arrangement facilitates the processing and manufacturing of the metal housing 110.

[0057] The first housing 111 is equipped with a recording switch 160, which is used by the recording device 010 to start or stop recording.

[0058] The first housing 111 is equipped with a mode switch 150, which allows the recording device 010 to switch recording modes.

[0059] The mode switch 150 and the recording switch 160 are set at intervals to reduce the possibility of accidental operation.

[0060] When the recording device 010 is placed against another object (tabletop), the outer wall of the first housing 111 faces away from the other object, while the outer wall of the second housing 112 faces the other object. This facilitates the operation of the recording switch 160 and the mode switch 150 on the first housing 111.

[0061] Alternatively, the recording device 010 can be mounted on the back of other devices (such as mobile phones). For ease of operation, the first housing 111 is positioned opposite the back of other devices, and the outer wall of the second housing 112 is opposite the back of other devices.

[0062] The recording device 010 includes a circuit board 120. The circuit board 120 integrates functions such as electrical signal processing, power management, and data storage, and can amplify, filter, digitize, and transmit audio signals.

[0063] Furthermore, the circuit board 120 is disposed within the receiving cavity 113 of the metal housing 110, which can prevent the circuit board 120 from being damaged by external forces.

[0064] A circuit board has opposing mounting and non-mounting sides. The mounting side is used to mount electronic components (such as processors, capacitors, inductors, resistors, and batteries), while the non-mounting side does not mount electronic components. Having only one side of the circuit board for mounting reduces cost and manufacturing complexity.

[0065] For example, circuit board 120 can be configured as a rigid circuit board to ensure the stability of the electronic components thereon. Circuit board 120 can also be configured as a flexible circuit board to accommodate mounting requirements.

[0066] The recording device 010 includes an antenna module 130. The antenna module 130 can transmit signals (in the form of electromagnetic waves), enabling the recording device 010 to have wireless communication capabilities.

[0067] Antenna module 130 can be configured as a ceramic antenna, which features miniaturization, integration, and high-frequency stability, and can be used in recording equipment.

[0068] Antenna module 130 is mounted on the mounting surface of circuit board 120, which is the surface of circuit board 120 that faces away from the second housing 112. Antenna module 130 is electrically connected to circuit board 120. This ensures that electrical signals from other electronic components (such as processors) are transmitted to antenna module 130 through printed wires on circuit board 120. Antenna module 130 converts the electrical signals into electromagnetic waves and transmits them, realizing the wireless communication function of recording device 010.

[0069] Alternatively, antenna module 130 can receive electromagnetic waves and convert them into electrical signals, which are then transmitted to other electronic components (such as a processor) via printed wires on the printed circuit board.

[0070] The circuit board 120 typically has a conductive layer (such as copper-clad laminate), which provides some shielding and absorption for signals. Therefore, a connecting region 121 is provided on the circuit board 120, and the position of the connecting region 121 corresponds to that of the antenna module 130. The signal emitted by the antenna module 130 can be transmitted outward through the connecting region 121, avoiding the absorption and reflection of the signal by the circuit board 120 and improving the signal transmission strength.

[0071] The connecting region 121 can penetrate the circuit board 120, allowing signals to be transmitted from the mounting surface of the circuit board 120 to the non-mounting surface through the connecting region 121.

[0072] For example, the shape of the connected region 121 can be set as a rectangular opening, a circular groove, a U-shaped groove, etc. The specific shape of the connected region 121 can be set according to actual needs.

[0073] The metal housing 110 can be divided into two parts. One part of the metal housing 110 faces the non-mounting plate surface, and the other part of the metal housing 110 faces the non-mounting plate surface. An insulating element 140 is embedded in the part of the metal housing 110 facing the non-mounting plate surface of the circuit board 120. The insulating element 140 is sealed to the housing wall of the metal housing 110. The metal housing 110, made of metal material, has a strong reflective and absorptive effect on electromagnetic waves, while the insulating element 140 is a non-conductive material, allowing signals emitted by the antenna module 130 to penetrate, thus avoiding absorption and reflection of signals emitted by the antenna module 130.

[0074] The insulating element 140 is positioned corresponding to the connecting area 121, enabling the signal to bypass the obstruction of the metal housing 110 and form a penetration path from the antenna module 130 to the outside of the metal housing 110.

[0075] Specifically, the metal housing 110 is provided with an opening 114, which corresponds to the connecting area 121. The insulating component 140 is sealed to the opening 114, preventing dust, moisture, etc. from entering the interior of the metal housing 110 through the connection between the insulating component 140 and the opening 114, thus ensuring the reliability of the metal housing 110.

[0076] For example, the waterproof rating at the connection between the insulation 140 and the opening 114 is set to IP67, enabling the recording device 010 to function normally after being immersed in water.

[0077] In some possible implementations, the opening 114 is configured as an oblong hole to improve its aesthetics. It is readily understood that the insulating element 140 can also be configured as an oblong hole to improve the aesthetics of the opening 114.

[0078] Understandably, the connecting area 121 on the circuit board 120 corresponding to the antenna module 130 position can prevent the circuit board 120 from blocking the signal, providing a channel for signal transmission. The portion of the metal housing 110 opposite the non-mounting surface of the circuit board 120 is embedded with an insulating element 140. The insulation of the insulating element 140 allows the signal emitted by the antenna module 130 to pass through. The signal emitted by the antenna module 130 can be transmitted from the antenna module 130 to the outside of the metal housing 110 through the path formed by the connecting area 121 and the insulating element 140, avoiding reflection and absorption of the signal emitted by the antenna by the metal housing 110, thereby solving the problem of signal instability or poor quality. At the same time, this ensures the heat dissipation of the metal housing 110 and its aesthetic appearance.

[0079] The recording device 010 also includes a mode switch 150 and a recording switch 160. The mode switch 150 is used to switch the operating mode of the recording device 010, and the recording switch 160 is used to control the start and stop of recording.

[0080] In some possible implementations, the insulating element 140 is made of plastic material, which has the advantages of good insulation, easy processing, and low cost. Plastic material has a low dielectric constant, allowing signals to pass through. The insulating element 140 made of plastic material allows signal transmission and can be manufactured into complex shapes through processes such as injection molding to adapt to different metal housing 110 structures.

[0081] For example, the insulating component 140 is made of acrylonitrile-butadiene-styrene (ABS) plastic and is integrally molded by injection molding to reduce the number of parts in the recording device 010.

[0082] In some possible implementations, the insulator 140 is made of ceramic material, which has the characteristics of high insulation, high temperature resistance, and strong chemical stability. Ceramic material has a low dielectric constant, which allows signals to pass through. The insulator 140 made of ceramic material allows signal transmission, minimizes signal attenuation, and maintains signal stability in harsh environments.

[0083] In some possible implementations, the insulating element 140 is made of glass, which has good insulation and aesthetics. Glass has a low dielectric constant, allowing signals to pass through. An insulating element 140 made of plastic allows signal transmission and also improves the aesthetics of the recording device 010.

[0084] For example, the insulating component 140 is made of borosilicate glass, and the edges of the insulating component 140 are sealed to the opening 114 of the metal housing 110 by a sealant. This ensures signal transmission and improves the sound quality of the recording device 010.

[0085] The mode switch 150 and the recording switch 160 are located on one side of the center line along the length of the first housing 111. When holding other devices, the position of the fingers is close to the switch, allowing the switching operation to be completed without changing the hand's grip posture. This conforms to the human body's movement trajectory, thereby improving operational efficiency.

[0086] Other electronic components are mounted on the surface of the circuit board 120 facing the first housing 111. The antenna module 130 is mounted on the surface of the circuit board 120 facing the first housing 111 to facilitate the layout of the antenna module 130.

[0087] Understandably, the first housing 111 is equipped with a mode switch 150 and a recording switch 160. Placing the insulating member 140 in the second housing 112 avoids interference between the insulating member 140 and the mode switch 150 and recording switch 160 on the first housing 111, ensuring ample space for the insulating member 140 to be installed on the bottom of the housing. Simultaneously, this ensures unobstructed switch operation.

[0088] In addition, the mode switch 150 and the recording switch 160 are located in the first housing 111 and are arranged in an orderly manner, so as to avoid the insulating part 140 being located in the first housing 111, which would make the appearance of the housing 110 cluttered and affect the aesthetics of the recording device 010.

[0089] Specifically, the insulating part is disposed in the middle of the second housing 112 along the width direction of the second housing 112 to increase the symmetry of the second housing 112 and improve the aesthetics of the recording device 010.

[0090] The projection of the connecting region 121 toward the second housing 112 is located within the insulating member 140. The signal transmitted by the antenna module 130 must pass through the connecting region 121 of the circuit board 120 and the insulating member 140 of the second housing 112 before it can be transmitted to the outside of the metal housing 110. When the projection of the connecting region 121 is completely located within the insulating member 140, the signal transmitted from the connecting region 121 can completely pass through the insulating member 140 and penetrate the metal housing 110 through the insulating member 140, avoiding metal obstruction, ensuring the integrity of signal transmission, and improving signal strength.

[0091] Furthermore, the copper layer of circuit board 120 is relatively thin, resulting in weaker signal reflection and absorption. In contrast, the metal casing 110 is much thicker than the copper layer. The larger size of the insulating component 140 allows for a wider signal transmission path within the thick metal casing 110, preventing signal attenuation caused by the size of the insulating component 140.

[0092] In some possible implementations, if the length of the insulating member 140 is less than 15mm, the area of ​​the insulating member 140 will be too small. Some of the signals emitted by the antenna module 130 may not be able to be transmitted to the outside of the metal housing 110 through the insulating member 140, and may be blocked or reflected by the metal housing 110, resulting in signal loss and unstable transmission.

[0093] If the length of the insulating component 140 is greater than 25mm, it will increase the space occupied by the insulating component 140 on the metal housing 110. At the same time, an excessively large insulating component 140 may weaken the structural strength of the metal housing 110, affecting the heat dissipation performance and overall aesthetics of the metal housing 110.

[0094] Therefore, the length of the insulating element 140 is greater than or equal to 15 mm and less than or equal to 25 mm. This arrangement ensures that the signal is transmitted outside the metal housing 110 to reduce signal loss, while avoiding structural interference, reduced strength of the metal housing 110, and reduced aesthetics due to excessive size.

[0095] In some possible implementations, if the width of the insulating element 140 is less than 3mm, the lateral space for signal penetration will be insufficient, and the antenna signal will be easily blocked by the metal housing 110 during propagation, resulting in signal loss and unstable transmission.

[0096] If the width of the insulating component 140 is greater than 7mm, it will increase the space occupied by the insulating component 140 on the metal housing 110. At the same time, an excessively large insulating component 140 may weaken the structural strength of the metal housing 110, affecting the heat dissipation performance and overall aesthetics of the metal housing 110.

[0097] Therefore, the width of the insulating element 140 is greater than or equal to 3 mm and less than or equal to 7 mm. This arrangement ensures that the signal is transmitted outside the metal housing 110 to reduce signal loss, while avoiding structural interference, reduced strength of the metal housing 110, and reduced aesthetics due to excessive size.

[0098] In some possible implementations, the length of the insulator 140 is any value between 18mm and 22mm. This configuration ensures that the signal is transmitted outside the metal housing 110 with reduced attenuation, while avoiding structural conflicts and a decrease in the strength of the metal housing 110 due to excessive size.

[0099] The length of the insulator 140 can be set to 18mm, 19mm, 20mm, 21mm, 22mm or any combination thereof.

[0100] In some possible implementations, the width of the insulating element 140 is any value between 4mm and 6mm. This configuration ensures that the signal is transmitted outside the metal housing 110 with reduced attenuation, while avoiding structural interference and a decrease in the strength of the metal housing 110 due to excessive size.

[0101] The width of the insulating element 140 can be set to 4mm, 4.5mm, 5mm, 6mm or any combination thereof.

[0102] The antenna module 130 includes an antenna body and a connector. The antenna body is electrically connected to the connector, and the antenna body is electrically connected to the circuit board 120 through the connector.

[0103] In some possible implementations, a first difference exists between the length of the connecting region 121 and the length of the antenna body. If this first difference is greater than 1 mm, and the length of the connecting region 121 is more than 1 mm longer than the length of the antenna body, the connector may be unable to connect to the circuit board 120 at the edge of the connecting region 121. If the length of the connecting region 121 is more than 1 mm shorter than the length of the antenna body, the connecting region 121 may be too small, preventing the signal from being transmitted outside the metal housing 110. Therefore, a first difference less than or equal to 1 mm ensures the stability of the connection between the connector and the circuit board 120, while also ensuring that the signal can be transmitted outside the metal housing 110, thus guaranteeing signal strength.

[0104] In some possible implementations, a second difference exists between the width of the connecting region 121 and the width of the antenna body. If this second difference is greater than 0.5 mm, the width of the connecting region 121 is more than 0.5 mm larger than the width of the antenna body, which may prevent the connector from connecting to the circuit board 120 at the edge of the connecting region 121. If the width of the connecting region 121 is more than 0.5 mm smaller than the width of the antenna body, the connecting region 121 may be too small, preventing the signal from being transmitted outside the metal housing 110. Therefore, a second difference of less than or equal to 0.5 mm ensures the stability of the connection between the connector and the circuit board 120 while ensuring that the signal can be transmitted outside the metal housing 110, thus guaranteeing signal strength.

[0105] Reference Figure 3 As shown, this application provides a card holder 020, which includes a base 210 and a enclosure 220. A magnetic element is provided inside the base 210 for securing the card holder 020.

[0106] The enclosure 220 is disposed on the base 210, and the base 210 and the enclosure 220 enclose a receiving space for accommodating electronic equipment.

[0107] Specifically, the recording device 010 can be housed in the storage space formed by the base 210 and the enclosure 220, and can be magnetically attached to the back of other devices by means of a magnetic attachment provided inside the base 210, so as to facilitate user carrying and improve the portability of the recording device 010. For example, when using it, the user can place the recording device 010 in the storage space of the card holder 020, and attach the card holder 020 to the back of other devices such as mobile phones and tablets.

[0108] For example, the magnetic attachment is set as a strong magnet to ensure the stability of the connection between the card holder 020 and other devices, and to ensure that the recording device 010 can be fixed in position relative to other devices, thereby ensuring the recording effect.

[0109] The magnetic chuck is set as a ring magnetic chuck, which has the characteristic of more uniform magnetic field distribution, making the connection between the card holder 020 and other devices more stable, and allowing the recording device 010 to be relatively fixed in position with other devices, thereby ensuring the recording effect.

[0110] In some possible implementations, the magnetic components are configured as multiple ring-shaped magnetic components, which are concentric and spaced apart. The combination of multiple ring-shaped magnetic components can superimpose the magnetic attraction force, further improving the connection stability of the card holder 020 with other devices and preventing the recording device 010 from falling off during use when moving with other devices.

[0111] It should be noted that the embodiments referred to in the specification, such as "one embodiment," "embodiment," "exemplary embodiment," and "some embodiments," may include specific features, structures, or characteristics, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0112] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "one" can be understood to convey either singular or plural usage.

[0113] It should be readily understood that the terms "on," "above," and "on top of" in this application should be interpreted in the broadest possible sense, such that "on" means not only "directly on" something, but also "on" something with an intermediate feature or layer in between. Furthermore, "above" or "on top of" includes not only the meaning of "above" or "on top of" something, but also the meaning of "on" or "on top of" something without an intermediate feature or layer in between (i.e., directly on) something.

[0114] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures.
