Description

Technical Field

[0001] This application relates to the field of projector audio technology, and in particular to a magnetically rechargeable projector speaker. Background Technology

[0002] With the widespread adoption of projectors in homes, the proportion of people using projectors for watching movies and listening to music has increased significantly. However, the relatively small size of projectors limits the size and number of speakers. This is because current projectors integrate speaker modules into their internal boxes. Since the optical engine, the core component of a projector, occupies a large space, there's no room for larger or bulkier speaker modules. Audio playback is typically achieved with only 1-3 small speaker modules, resulting in less than optimal sound quality when watching movies or listening to music on a projector. Utility Model Content

[0003] The purpose of this application is to provide a magnetically rechargeable projector speaker to solve the problem of poor sound quality in projectors with limited space. The specific technical solution is as follows:

[0004] This application provides a magnetically charging projector speaker, comprising: at least two external speakers, each external speaker having a battery module inside, and a magnetic attractor and a receiving coil on one side of each external speaker; a projector body for cooperating with the external speakers, the projector body having magnetic engaging components and a power supply coil on at least two sides; the magnetic engaging components and the magnetic attractor being positioned correspondingly, the power supply coil and the receiving coil being positioned correspondingly, the external speakers being magnetically connected to the projector body, and when magnetically connected, the projector body charging the external speakers; and the projector body and the external speakers communicating via Wi-Fi.

[0005] In some embodiments, the magnetic attraction component and the power supply coil are disposed on the outer casing of the projector body and located inside the outer casing; the magnetic attraction component and the power receiving coil are disposed on the outer casing of the external speaker and located inside the outer casing.

[0006] In some embodiments, the magnetic attraction component and the power supply coil are bonded to or embedded in the inner side of the housing; the magnetic attraction component and the power receiving coil are bonded to or embedded in the inner side of the housing.

[0007] In some embodiments, two external speakers are provided and are located on opposite sides of the projector body.

[0008] In some embodiments, on the opposite side walls of the housing, the power supply coil is centrally or slightly above the center, and the magnetic attraction component is strip-shaped and located at one or more of the positions above, below, left, and right of the power supply coil; on one side wall of the housing, the power receiving coil is centrally located, and the magnetic attraction component is strip-shaped and located at one or more of the positions above, below, left, and right of the power receiving coil, and is correspondingly arranged to the power supply coil.

[0009] In some embodiments, on the opposite side walls of the housing, the power supply coil is centrally or slightly above the center, and the magnetic attraction component is arranged in a ring around the outer periphery of the power supply coil; on one side wall of the housing, the power receiving coil is centrally located, and the magnetic attraction component is arranged in a ring around the outer periphery of the power receiving coil.

[0010] In some embodiments, the magnetic attracting element is an iron block, and the magnetic attraction mating element is a magnet; or, the magnetic attracting element is a magnet, and the magnetic attraction mating element is an iron block or a magnet.

[0011] The projector external speaker provided in this application embodiment, by adding an external speaker to the projector body, is not limited by the small internal space of the projector body. In other words, it adds a speaker module outside the projector body, thereby increasing the number and quality of speakers to improve audio effects. The external speaker is magnetically connected to the projector body, making it very easy to detach. When the external speaker and projector need to be used together, they can be magnetically attached by aligning them, and the projector is then a projector with external speakers. When the user needs to watch movies or listen to music, the external speaker can be easily removed. The projector and speaker can be set up separately, but can achieve the effect of joint use. Each external speaker is an independent speaker and can be placed in different positions as needed by the user. This can better reflect the stereo effect. Because the external speaker has more space, it can also produce better sound effects. The projector body has a power supply coil, and the external speaker has a power receiving coil. The external speaker has a built-in battery module, and when the projector body and the external speaker are magnetically connected, the external speaker can be wirelessly charged. The external speakers communicate with the projector via Wi-Fi, eliminating the hassle of wiring and allowing for flexible speaker placement to suit user needs. Compared to Bluetooth, Wi-Fi offers more stable transmission, wider bandwidth, higher transmission speeds, and lower latency. It also boasts a longer communication range, stronger wall penetration, and the ability to connect more devices (up to 20 or more) in various combinations.

[0012] Of course, any product implementing this application does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] 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, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art based on this application are within the scope of protection of this application.

[0026] Due to the limited size of the projector body, it's impossible to fit a larger or more bulky speaker module. Audio playback is typically achieved using only 1-3 very small speaker modules, resulting in poor sound quality. To address this issue, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown in the figure, this application embodiment provides a magnetic charging projector body 2 speaker, which includes at least two external speakers 1. Each external speaker 1 contains a battery module (not shown in the figure), and one side of each external speaker 1 has a magnetic suction element 111 and a receiving coil 112. The projector body 2, used to cooperate with the external speakers 1, has magnetic suction elements 211 and receiving coils 212 on at least two sides. The magnetic suction elements 211 and 111 are positioned correspondingly, and the receiving coils 212 and 112 are positioned correspondingly. The external speakers 1 and the projector body 2 are magnetically connected, and when magnetically connected, the projector body 2 charges the external speakers 1. The projector body 2 and the external speakers 1 communicate via Wi-Fi.

[0027] This application adds an external speaker 1 to the projector body 2, overcoming the limitations of the limited internal space of the projector body 2. This involves adding a speaker module outside the projector body 2, thereby increasing the number and quality of speakers to improve audio performance. The external speaker 1 is magnetically connected to the projector body 2, making it very easy to detach. When the external speaker 1 is needed for combined use with the projector, simply align them and they will magnetically attach, making the projector a projector with the external speaker 1. When the user wants to watch a movie or listen to music, the external speaker 1 can be easily removed. The projector and speaker can be used separately but together. Each external speaker 1 is an independent speaker and can be placed in different locations as needed. This allows for a better stereo effect. Because the external speaker 1 has more space, it can also produce better sound quality.

[0028] like Figure 4 As shown, the projector body 2 contains a power supply coil 212, such as... Figure 5 As shown, the external speaker 1 has a power receiving coil 112 and a built-in battery module. When the projector body 2 is magnetically connected to the external speaker 1, it can wirelessly charge the external speaker 1.

[0029] The external speaker 1 communicates with the projector unit 2 via Wi-Fi, eliminating the hassle of wiring and allowing for flexible placement of the external speaker 1 according to user needs. Compared to Bluetooth, Wi-Fi offers more stable transmission and wider bandwidth, along with higher transmission speeds and lower latency. Furthermore, Wi-Fi has a longer communication range, stronger wall-penetrating ability, and can connect to more than 20 devices, supporting various combinations.

[0030] External speaker 1 has a built-in WIFI module, which allows it to be used as a standalone WIFI speaker. That is, external speaker 1 can be used independently as a WIFI speaker even when not connected to the projector unit 2, further enhancing its added value.

[0031] Understandably, when the projector body 2 has built-in speakers, the external speaker 1 can be used as an accessory. If there are no built-in speakers, the external speaker 1 can perfectly replace the built-in speakers.

[0032] By using an external speaker 1, the limited space inside the projector body 2 is no longer a constraint, allowing for an increase in the number and quality of speakers, thus improving sound quality. Since the external speaker 1 can be separated from the projector body 2, it effectively adds more sound channels. For example, if the projector body 2 originally has two built-in speakers (stereo 2.0), adding the external speaker 1 can achieve stereo 3.0, 4.0, 5.0, etc., resulting in a richer listening experience. Furthermore, the external speaker 1 can be placed freely. Due to the Wi-Fi communication between the external speaker 1 and the projector body 2, its placement is wider, enabling effects such as surround sound.

[0033] In some embodiments of this application, such as Figure 4 , Figure 5 As shown, the magnetic attraction component 211 and the power supply coil 212 are disposed on the outer shell 21 of the projector body 2 and are located inside the outer shell 21; the magnetic attraction component 111 and the power receiving coil 112 are disposed on the outer shell 11 of the external speaker 1 and are located inside the outer shell 11.

[0034] In this embodiment, the magnetic attraction component 211 and the power supply coil 212 are disposed on the outer shell 21 of the projector body 2, which can reduce changes in the internal structure of the projector body 2. Furthermore, the magnetic attraction component 211 and the power supply coil 212 are disposed inside the outer shell 21, and the outer shell 21 can protect the power supply coil 212 and the magnetic attraction component 211.

[0035] By placing the magnetic connector 111 and the receiving coil 112 on the housing 11 of the external speaker 1, changes to the internal structure of the external speaker 1 can be reduced. This allows for magnetic connection between various projector models and the external speaker 1, broadening its applicability. Furthermore, the magnetic connector 111 and the receiving coil 112 are located inside the housing 11, providing protection for them.

[0036] In addition, it is easy to replace the power supply coil 212 or the power receiving coil 112 when there is a problem, which can reduce production costs.

[0037] Specifically, such as Figure 4 , Figure 5 As shown, the magnetic attraction component 211 and the power supply coil 212 are bonded to the inside of the housing 21 or embedded in the inside of the housing 21; the magnetic attraction component 111 and the power receiving coil 112 are bonded to the inside of the housing 11 or embedded in the inside of the housing 11.

[0038] The magnetic connector 211 and the power supply coil 212 are bonded or embedded inside the housing 21, making the connection simple and requiring no changes to the structure of the housing 21. From the outside of the projector body 2, there are no significant changes, resulting in a clean and elegant appearance.

[0039] The magnetic attachment 111 and the receiving coil 112 are bonded or embedded inside the housing 11. The connection method is simple and does not require changing the structure of the housing 11. There is not much change when viewed from the outside of the external speaker 1, making the external speaker 1 look simple and elegant.

[0040] When the magnetic coupling component 211 and the power supply coil 212 are embedded inside the outer casing 21 of the projector body 2, the inner side of the outer casing 21 is provided with a magnetic coupling component receiving groove and a power supply coil receiving groove. This allows the magnetic coupling component 211 and the power supply coil 212 to be directly installed into their corresponding receiving grooves, eliminating the alignment process and improving installation efficiency. After installation, the support provided by the receiving grooves enhances installation stability.

[0041] Similarly, when the magnetic casing component 111 and the receiving coil 112 are embedded inside the housing 11 of the external speaker 1, the housing 11 has a magnetic casing component receiving slot and a receiving coil receiving slot. This allows the magnetic casing component 111 and the receiving coil 112 to be directly inserted into their respective receiving slots, eliminating the need for alignment and improving installation efficiency. After installation, the receiving slots provide greater support, resulting in higher installation stability.

[0042] As one possible implementation, such as Figure 1 , Figure 2 , Figure 3As shown, there are two external speakers 1, which are positioned on opposite sides of the projector body 2. The two external speakers 1 are symmetrically arranged, making the projector look more aesthetically pleasing.

[0043] As one possible implementation, such as Figure 4 , Figure 5 As shown, on the opposite side walls of the outer casing 21, the power supply coil 212 is centrally or slightly above the center, and the magnetic attraction component 211 is arranged around the outer periphery of the power supply coil 212; on one side wall of the outer casing 11, the power receiving coil 112 is centrally located, and the magnetic attraction component 111 is arranged around the outer periphery of the power receiving coil 112.

[0044] The magnetic locating component 211 is arranged around the power supply coil 212, and the magnetic locating component 111 is arranged around the power receiving coil 112. In this way, as long as the power supply coil 212 and the power receiving coil 112 are the same size, the positions of the magnetic locating component 211 and the magnetic locating component 111 can be determined accordingly. This simplifies the process of precisely aligning the magnetic locating component 211 and the magnetic locating component 111 during the machining process, which helps to reduce the machining difficulty.

[0045] As one possible implementation, such as Figure 6 , Figure 7 As shown, on the opposite side walls of the outer casing 21, the power supply coil 212 is centrally or slightly above the center, and the magnetic attraction component 211 is strip-shaped and is located at one or more positions above, below, to the left and to the right of the power supply coil 212; on one side wall of the outer casing 11, the power receiving coil 112 is centrally located, and the magnetic attraction component 111 is strip-shaped and is located at one or more positions above, below, to the left and to the right of the power receiving coil 112, and is correspondingly arranged with the power supply coil 212.

[0046] The power supply coil 212 is positioned in the center or at the top, which makes efficient use of the space on the side wall of the projector body 2. After magnetic connection with the external speaker 1, the external speaker 1 is located in the middle or slightly above the middle of the projector body 2, which helps to reduce the overall size of the two connected components. Since the external speaker 1 is generally small, the power receiving coil 112 can be positioned in the center, which also makes efficient use of the space on the side wall of the external speaker 1.

[0047] The magnetic attractor 111 and the magnetic mating component 211 are strip-shaped, and can be a single strip or a strip composed of multiple segments. The magnetic attractor 111 and the magnetic mating component 211 are located on one side, two sides, or more than two sides of the coil, allowing for a reasonable arrangement of their positions based on the space available on the side walls of the projector body 2 and the external speaker 1. The magnetic attractor 111 and the magnetic mating component 211 can be positioned in multiple locations, increasing the magnetic attraction area between the projector body 2 and the external speaker 1, thus improving the connection stability and reliability between them.

[0048] As one possible implementation, such as Figure 8 , Figure 9 As shown, on the opposite side walls of the outer casing 21, the power supply coil 212 is centrally or slightly above the center, and the magnetic attraction component 211 is arranged on both sides of the power supply coil 212 along the diagonal direction of the side wall of the outer casing 21. On one side wall of the casing 11, the power receiving coil 112 is centrally located, and the magnetic attraction component 111 is arranged on both sides of the power receiving coil 112 along the diagonal direction of the side wall of the casing 11.

[0049] The magnetic attraction components 211 are arranged diagonally along the sidewalls of the housing 21 on both sides of the power supply coil 212. They can be arranged along both diagonal directions or only along one diagonal direction. Arranging the magnetic attraction components 211 diagonally on both sides of the power supply coil 212 makes efficient use of the space on the sidewalls of the housing 21, and arranging them on both diagonals increases the magnetic attraction area and improves the magnetic attraction effect.

[0050] The magnetic attractors 111 are arranged on both sides of the current receiving coil 112 along the diagonal direction of the side wall of the housing 11. They can be arranged along both diagonal directions or only along one diagonal direction. The arrangement of the magnetic attractors 111 along both sides of the current receiving coil 112 along the diagonal direction can make reasonable use of the space of the side wall of the housing 11, and the arrangement of magnetic attractors 111 on both diagonals can increase the magnetic attraction area and improve the magnetic attraction effect.

[0051] In some embodiments of this application, the magnetic attractor 111 is an iron block, and the magnetic mating component 211 is a magnet; or, the magnetic attractor 111 is a magnet, and the magnetic mating component 211 is an iron block or a magnet. This application does not impose specific limitations on the shape and size of the magnetic attractor 111 and the magnetic mating component 211, as long as the magnetic mating of the two can be achieved.

[0052] The above description is merely a preferred embodiment of this application and is not intended to limit the scope of protection of this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application are included within the scope of protection of this application.
