Description
Technical Field
[0001] This utility model relates to the field of headphone technology, specifically to a dual-screen display headphone. Background Technology
[0002] There are two main types of headphones: smaller, portable in-ear headphones and larger over-ear headphones. Over-ear headphones typically have only one headphone stand, which is designed in an arched shape to provide a snug fit around the user's ears. Traditional over-ear headphones require an audio cable to connect to devices like phones, music players, and laptops to play audio. Bluetooth headphones later emerged, allowing wireless connection to devices without an audio cable. However, traditional Bluetooth over-ear headphones are limited to music playback; they don't display real-time playback status or offer a clear visual display.
[0003] An existing type of over-ear Bluetooth headset features displays on both the left and right earpieces to show playback status and image information, aiming to provide a visual experience. However, this headset uses only a single Bluetooth circuit, which must simultaneously handle audio streaming and display data transmission, including lyrics and images. A single Bluetooth circuit is prone to insufficient bandwidth and data congestion, leading to audio stuttering or display delays.
[0004] Therefore, a more optimized dual-screen display headset needs to be considered. Utility Model Content
[0005] The main purpose of this invention is to provide a dual-screen display headset that can avoid single-channel communication congestion and improve communication fault tolerance.
[0006] To achieve the aforementioned main objectives, the dual-screen display headset provided by this utility model includes a main Bluetooth control circuit, a first secondary Bluetooth control circuit, a second secondary Bluetooth control circuit, a first display screen, and a second display screen. The main Bluetooth control circuit interacts with an external terminal via a first antenna. At least one of the first and second secondary Bluetooth control circuits interacts with an external terminal via a corresponding antenna. At least one of the first and second secondary Bluetooth control circuits is also electrically connected to the main Bluetooth control circuit. The first and second secondary Bluetooth control circuits are electrically connected. The first display screen is electrically connected to the first secondary Bluetooth control circuit, and the second display screen is electrically connected to the second secondary Bluetooth control circuit.
[0007] As can be seen from the above scheme, the dual-screen display headset of this utility model uses three Bluetooth control circuits: a main Bluetooth control circuit, a first secondary Bluetooth control circuit, and a second secondary Bluetooth control circuit. The main Bluetooth control circuit can handle the core information interaction tasks with the external terminal, such as receiving audio streams and device control commands. At least one of the first and second secondary Bluetooth control circuits interacts with the external terminal and can receive personalized display data required by the display screen, such as lyrics and emoticons, through the corresponding antenna, avoiding single-channel communication congestion. Simultaneously, at least one of the first and second secondary Bluetooth control circuits is electrically connected to the main Bluetooth control circuit, enabling data synchronization and command transmission. Furthermore, the electrical connection between the first and second secondary Bluetooth control circuits allows for data exchange. Even if one secondary Bluetooth control circuit experiences a communication failure with the main Bluetooth control circuit, information can still be indirectly obtained through the other secondary Bluetooth control circuit, improving communication fault tolerance.
[0008] In a further proposed solution, the main Bluetooth control circuit uses a BT Bluetooth chip; the first and second secondary Bluetooth control circuits both use BLE Bluetooth chips.
[0009] It can be seen that the main Bluetooth control circuit uses a BT Bluetooth chip, which can handle data with high power consumption, while the first and second secondary Bluetooth control circuits both use BLE Bluetooth chips, which can handle data with low power consumption.
[0010] In a further embodiment, the dual-screen display headset also includes a microphone circuit, which is electrically connected to the main Bluetooth control circuit.
[0011] Therefore, it can be seen that audio can be acquired by setting up a microphone circuit.
[0012] In a further embodiment, the microphone circuit includes a main microphone circuit, a first noise-canceling microphone circuit, and a second noise-canceling microphone circuit, all of which are electrically connected to the main Bluetooth control circuit.
[0013] Therefore, setting up a main microphone circuit can be used to achieve voice calls. Setting up a first noise-canceling microphone circuit and a second noise-canceling microphone circuit can achieve noise reduction for the left and right earphones, improving sound quality.
[0014] In a further embodiment, the dual-screen display headphones also include a button control circuit, which is electrically connected to the main Bluetooth control circuit.
[0015] Therefore, by setting up a button control circuit, it is easy to control the switching of headphone functions.
[0016] In a further embodiment, the dual-screen display headphones also include an indicator light circuit, which is electrically connected to the main Bluetooth control circuit.
[0017] Therefore, setting up an indicator light circuit can indicate the status of the headphones, making it easier to remind the user.
[0018] In a further embodiment, the dual-screen display headset also includes a power supply circuit that provides power to the main Bluetooth control circuit, the first secondary Bluetooth control circuit, the second secondary Bluetooth control circuit, the first display screen, and the second display screen.
[0019] Therefore, by setting up a power supply circuit, it is easy to supply power to the circuit components of the headphones.
[0020] In a further embodiment, a first switch control circuit is provided between the power supply terminal of the first secondary Bluetooth control circuit and the output terminal of the power supply circuit, and the control terminal of the first switch control circuit is electrically connected to the main Bluetooth control circuit; and / or a second switch control circuit is provided between the power supply terminal of the second secondary Bluetooth control circuit and the output terminal of the power supply circuit, and the control terminal of the second switch control circuit is electrically connected to the main Bluetooth control circuit.
[0021] Therefore, by setting up a switch control circuit, the main Bluetooth control circuit can control the power supply of the first and second Bluetooth control circuits, so that power is only supplied when the first and second Bluetooth control circuits are needed, thus reducing power consumption.
[0022] In a further embodiment, the power supply circuit includes a charging interface, a charging control circuit, and a rechargeable battery. The input terminal of the charging interface is electrically connected to the input terminal of the charging control circuit, and the rechargeable battery is electrically connected to the charging control circuit.
[0023] Therefore, it is evident that by incorporating a charging control circuit and a rechargeable battery, the power life of headphones can be easily improved. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation
[0030] Dual-screen display headset example: like Figure 1 As shown, in this embodiment, the dual-screen display headset includes a main Bluetooth control circuit 1, a first secondary Bluetooth control circuit 2, a second secondary Bluetooth control circuit 3, a first display screen 4, and a second display screen 5.
[0031] The main Bluetooth control circuit 1 interacts with the external terminal via the first antenna 11. At least one of the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 interacts with the external terminal via its corresponding antenna. In this embodiment, the first secondary Bluetooth control circuit 2 interacts with the external terminal via the second antenna 21, and the second secondary Bluetooth control circuit 3 interacts with the external terminal via the third antenna 31.
[0032] In this embodiment, the main Bluetooth control circuit 1 uses a BT Bluetooth chip, while the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 both use BLE Bluetooth chips. The main Bluetooth control circuit 1, using a BT Bluetooth chip, can handle data with higher power consumption, while the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3, using BLE Bluetooth chips, can handle data with lower power consumption. Preferably, the BT Bluetooth chip is a BT8931H model chip, and the BLE Bluetooth chip is an AB5681G model chip.
[0033] In this embodiment, both the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 are electrically connected to the main Bluetooth control circuit 1. Alternatively, only one of the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 can be electrically connected to the main Bluetooth control circuit 1. The electrical connection between the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 and the main Bluetooth control circuit 1 enables information exchange between the main Bluetooth control circuit 1 and the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3.
[0034] In this embodiment, the first Bluetooth control circuit 2 and the second Bluetooth control circuit 3 are electrically connected. This enables the first Bluetooth control circuit 2 and the second Bluetooth control circuit 3 to exchange data.
[0035] In this embodiment, the first display screen 4 is electrically connected to the first secondary Bluetooth control circuit 2, and the second display screen 5 is electrically connected to the second secondary Bluetooth control circuit 3. The first display screen 4 is located on the left earphone, and the second display screen 5 is located on the right earphone.
[0036] The first display screen 4 and the second display screen 5 are connected to their respective secondary Bluetooth control circuits, which enables both independent control of the display functions and linkage. For example, the first display screen 4 is driven by the first secondary Bluetooth control circuit 2, and the second display screen 5 is driven by the second secondary Bluetooth control circuit 3. This allows the first display screen 4 and the second display screen 5 to display different content, such as the first display screen 4 displaying a singer's poster and the second display screen 5 displaying lyrics in a marquee, thus meeting the user's personalized display needs.
[0037] In this embodiment, the dual-screen display headset also includes a microphone circuit 6, which is electrically connected to the main Bluetooth control circuit 1. See also... Figure 2 The microphone circuit 6 includes a main microphone circuit 61, a first noise-canceling microphone circuit 62, and a second noise-canceling microphone circuit 63. All three circuits are electrically connected to the main Bluetooth control circuit 1. The first noise-canceling microphone circuit 62 is located in the left earpiece, and the second noise-canceling microphone circuit 63 is located in the right earpiece. The main microphone circuit 61 enables voice calls. The first and second noise-canceling microphone circuits 62 and 63 work together to collect ambient noise, thereby reducing audio noise in both the left and right earpieces and improving sound quality.
[0038] In this embodiment, the dual-screen display headphones also include a button control circuit 7, which is electrically connected to the main Bluetooth control circuit 1. By setting up the button control circuit 7, it is easy to control the switching of headphone functions. The function buttons of the button control circuit 7 can be configured as needed; for example, the button control circuit 7 may include a power button, volume adjustment buttons, etc.
[0039] In this embodiment, the dual-screen display headset also includes an indicator light circuit 8, which is electrically connected to the main Bluetooth control circuit 1. By setting the indicator light circuit 8, the status of the headset can be indicated, such as battery level and charging status, which can easily remind the user.
[0040] In this embodiment, the dual-screen display headset also includes a power supply circuit 9, which provides power to the main Bluetooth control circuit 1, the first secondary Bluetooth control circuit 2, the second secondary Bluetooth control circuit 3, the first display screen 4, the second display screen 5, the microphone circuit 6, the button control circuit 7, and the indicator light circuit 8.
[0041] See Figure 3The power supply circuit 9 includes a charging interface 91, a charging control circuit U1, and a rechargeable battery 92. The input terminal of the charging interface 91 is electrically connected to the input terminal of the charging control circuit U1, and the rechargeable battery 92 is electrically connected to the charging control circuit U1. By including the charging control circuit U1 and the rechargeable battery 92, charging can be facilitated, improving the power supply life of the headphones. In this embodiment, the power supply circuit 9 also includes an overvoltage protection circuit U2, which is located between the charging interface 91 and the input terminal of the charging control circuit U1. By including the overvoltage protection circuit U2, overvoltage protection can be provided for the power supply circuit to prevent circuit damage.
[0042] See Figure 4 and Figure 5 In this embodiment, a first switch control circuit 93 is provided between the power supply terminal of the first secondary Bluetooth control circuit 2 and the output terminal of the power supply circuit 9, and a second switch control circuit 94 is provided between the power supply terminal of the second secondary Bluetooth control circuit 3 and the output terminal of the power supply circuit 9. The control terminals of both the first switch control circuit 93 and the second switch control circuit 94 are electrically connected to the main Bluetooth control circuit 1. By providing the switch control circuits, the main Bluetooth control circuit 1 can control the power supply of the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3, facilitating power supply only when the first secondary Bluetooth control circuit 2 and the second secondary Bluetooth control circuit 3 are needed, thus reducing power consumption.
[0043] As described above, the dual-screen display headset of this invention utilizes three Bluetooth control circuits: a main Bluetooth control circuit 1, a first secondary Bluetooth control circuit 2, and a second secondary Bluetooth control circuit 3. The main Bluetooth control circuit 1 handles core information interaction tasks with external terminals, such as receiving audio streams and device control commands. At least one of the first secondary Bluetooth control circuits 2 and 3 interacts with the external terminal, receiving personalized display data such as lyrics and emoticons via its corresponding antenna, thus avoiding single-channel communication congestion. Simultaneously, at least one of the first secondary Bluetooth control circuits 2 and 3 is electrically connected to the main Bluetooth control circuit 1. The main Bluetooth control circuit 1 enables data synchronization and command transmission. Furthermore, the electrical connection between the first secondary Bluetooth control circuits 2 and 3 allows for data exchange. Even if one secondary Bluetooth control circuit experiences a communication failure with the main Bluetooth control circuit 1, information can still be indirectly obtained through the other secondary Bluetooth control circuit, improving communication fault tolerance.
[0044] It should be noted that the above are only preferred embodiments of the present utility model, but the design concept of the utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall also fall within the protection scope of the present utility model.
