Description

Technical Field

[0001] This utility model relates to the field of audio equipment technology, specifically to a speaker that automatically switches the input and output attributes of the audio interface. Background Technology

[0002] In the field of audio equipment, speakers, as the core terminal component of an audio system, undertake the crucial task of converting electrical signals into sound energy. Functionally, speakers receive audio signals, amplify them using the built-in power amplifier within the main unit or subwoofer enclosure, convert the processed signal back into sound, and radiate it into space, ultimately achieving sound reproduction and amplification so that users can listen directly.

[0003] However, most existing left and right channel speakers use separate audio input and output interfaces. For example, the left channel speaker has an audio input interface to connect to the audio source, while the right channel speaker needs to be connected to the left channel speaker's audio input interface via an audio output interface. This design requires users to strictly distinguish between the audio interface types, but in practice, because the audio input and output interfaces look similar and lack clear labeling, users are very prone to connection errors. Market research data shows that over 65% of users have experienced interface confusion when connecting stereo speakers for the first time.

[0004] The above shortcomings need to be addressed. Utility Model Content

[0036] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. It is also declared that the embodiments described below are only for explaining this utility model and are not intended to limit this utility model.

[0037] It should be noted that the term "connection" and other such terms should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components, unless otherwise explicitly defined.

[0038] Please see Figures 1 to 3This utility model provides a speaker with automatic switching audio interface input / output attributes, including a main control chip 1, a main / secondary speaker connection port 2, a position sensor 3, an audio input interface 4, a power module 5, and a power amplifier module 6. The main control chip 1 is connected to the main / secondary speaker connection port 2, the position sensor 3, the audio input interface 4, the power module 5, and the power amplifier module 6. The main / secondary speaker connection port 2 is a digital audio input / output interface, such as an SPDIF interface, with both input and output working modes, which can be flexibly switched according to the instructions of the main control chip 1. The position sensor 3 is used to detect the speaker's placement orientation information in real time or at regular intervals, providing a basis for the speaker to determine its host or slave role. The audio input interface 4 is responsible for receiving audio signals from external audio sources, providing a sound source for the speaker. After the audio input interface 4 is connected to the main control chip 1, it can accurately transmit the received signal to the power amplifier module 6 under the control of the main control chip 1, ensuring stable audio signal input. The power module 5 provides a stable power supply to all components of the speaker, ensuring the normal operation of the main control chip 1, position sensor 3, power amplifier module 6, etc., and is a fundamental component for the normal operation of the speaker. The main control chip 1, acting as the brain of the speaker, determines whether the speaker is a master or slave based on the placement orientation information detected by the position sensor 3, and switches the operating mode of the master / slave speaker connection port 2 accordingly. For example, when the main control chip 1 determines the speaker is a master based on the placement orientation information detected by the position sensor 3 (e.g., the speaker is placed vertically upright), it configures the master / slave speaker connection port 2 to output mode through register configuration or pin level control, at which point the master / slave speaker connection port 2 becomes an audio output interface. When the main control chip 1 determines the speaker is a slave based on the placement orientation information detected by the position sensor 3 (e.g., the speaker is placed vertically backwards), it configures the master / slave speaker connection port 2 to input mode through register configuration or pin level control, at which point the master / slave speaker connection port 2 becomes an audio input interface 4.

[0039] In this embodiment, since there is only one main and auxiliary speaker connection port 2, and the main control chip 1 can automatically switch the input and output attributes of the main and auxiliary speaker connection port 2 according to the placement direction information detected by the position sensor 3, the user does not need to distinguish the input and output attributes of the main and auxiliary speaker connection port 2, avoiding connection errors caused by interface confusion, making the connection between the main and auxiliary speakers simpler, and allowing users who are using the speakers for the first time to easily complete the connection.

[0040] Please see Figure 2 In one embodiment, the main control chip 1 is a Bluetooth main control chip. The Bluetooth main control chip enables the speaker to have Bluetooth wireless connectivity, eliminating the need for users to use traditional audio cables to connect audio source devices such as mobile phones and tablets. This greatly simplifies the device connection process; users only need to enable the device's Bluetooth function and perform a simple pairing to quickly establish an audio transmission channel, improving ease of use and flexibility.

[0041] Please see Figure 4 In one embodiment, the position sensor 3 is a gyroscope. A gyroscope is a sensor capable of accurately measuring the angular velocity and rotation angle of an object. Using it as the position sensor 3 in a speaker allows for highly accurate detection of the speaker's orientation, including tilt angle and rotation direction. This provides the main control chip 1 with a reliable basis for accurately determining whether the speaker is a master or slave device, thus ensuring more accurate automatic switching of audio interface input / output attributes. Simultaneously, the gyroscope has a fast response characteristic, enabling real-time sensing of changes in the speaker's orientation.

[0042] In one embodiment, audio input interface 4 is an HDMI ARC input interface. The HDMI ARC input interface supports the transmission of high-definition audio signals and can transmit high-quality multi-channel audio formats including Dolby Digital and DTS. Compared with traditional audio interfaces, the HDMI ARC input interface can provide a richer and more realistic audio experience, allowing users to enjoy cinema-quality sound effects.

[0043] Please see Figure 5 , Figure 6 In one embodiment, the power module 5 includes a power conversion circuit 501 and an adapter power supply 502. The power conversion circuit 501 is connected to both the adapter power supply 502 and the main control chip 1. The power conversion circuit 501 converts and regulates the voltage input to the adapter power supply 502, ensuring that the voltage output to the main control chip 1 and other modules remains stable within a suitable range. The adapter power supply 502 adapts to different external power specifications, such as common AC 110V-240V mains voltages, or different DC power input specifications, enabling the speaker to be used in various power environments. Whether at home, in the office, or outdoors (with a suitable power adapter), there is no need to worry about power compatibility issues, greatly improving the speaker's versatility and applicability.

[0044] Please see Figure 7 In one embodiment, the power amplifier module 6 includes a power amplifier chip 601, a full-range speaker 602, and a subwoofer 603. The power amplifier chip 601 is connected to the full-range speaker 602, the subwoofer 603, and the main control chip 1. The full-range speaker 602 can cover a wide frequency range and can reproduce the sound details of vocals, mid-to-high frequency instruments, etc., while the subwoofer 603 focuses on the reproduction of low-frequency sounds, such as drums and bass. By simultaneously driving the full-range speaker 602 and the subwoofer 603 with the power amplifier chip 601, the speaker can output rich high, mid, and low frequency sounds at the same time, making the sound layers more distinct and bringing users a fuller and more three-dimensional listening experience, as if they were in a live music concert.

[0045] Please see Figure 8, Figure 9 , in one embodiment, the speaker further comprises a light module 7, and the light module 7 is connected to the main control chip 1. Wherein, the light module 7 is an RGB color-changing LED strip, which can emit lights of multiple colors and realize dynamic changes of parameters such as light color, brightness and flickering frequency. When the speaker plays music, the RGB color-changing LED strip can change the light effect according to the rhythm and melody of the music, create a visual atmosphere matching the music, so that users can obtain gorgeous visual enjoyment while enjoying music, which enhances the overall entertainment and interestingness of the speaker. Wherein, the main control chip 1 can also switch the light mode of the RGB color-changing LED strip according to the placement direction information detected by the position sensor 3, realizing the linkage between the speaker function and the light effect. For example, when the speaker is placed in a first vertical placement direction, the RGB color-changing LED strip displays a specific light mode; when the speaker is placed in a second vertical placement direction, it switches to another light mode. This linked design not only increases the technological sense and interestingness of the speaker, but also allows users to intuitively know the working state of the speaker through the light mode, which improves user experience.

[0046] Refer to Figure 10 , in one embodiment, the speaker further comprises a key module 8, and the key module 8 is connected to the main control chip 1. The key module provides users with an intuitive and convenient local operation mode, so that users do not need to rely on mobile phone APPs or other remote control devices, and can quickly implement various functions only by directly pressing the keys on the speaker, such as power on / off, volume adjustment, track switching, mode selection (such as Bluetooth mode, audio input mode, etc.).

[0047] Preferably, the key module 8 is a touch key. Since the touch key does not have the physical travel of traditional mechanical keys, users can complete the operation only by gently touching the key area, making the operation process easier and faster. Moreover, the surface of the touch key can be designed to be flatter and simpler, which has higher integration with the overall appearance of the speaker and makes the appearance of the speaker more beautiful.

[0048] Refer to Figure 11 , in one embodiment, the speaker further comprises an optical fiber input interface 9, and the optical fiber input interface 9 is connected to the main control chip 1. The optical fiber input interface 9 is used for connecting to the Internet through a network cable, so that the speaker can access abundant online resources and services. For example, users can directly listen to the massive music libraries of various online music platforms on the speaker without transferring through other devices; they can also listen to content such as Internet radio and audiobooks, which greatly expands the functions and application scenarios of the speaker. In addition, the speaker can also be integrated with a smart home system, and realize linked control with other smart devices through the network interface, for example, automatically playing specific music according to time, cooperating with other smart devices to create a home atmosphere, etc.

[0049] Refer to Figure 12 In one embodiment, the speaker further includes a USB sound card interface 10, which is connected to the main control chip 1. The USB sound card interface provides the speaker with the possibility of connecting various external audio devices. A speaker with a USB sound card interface is no longer just a simple audio playback device, but a comprehensive audio device integrating audio playback, recording, and processing functions. Users can connect audio input devices such as microphones and musical instruments to the speaker via the USB sound card interface to achieve audio recording. For example, music lovers can connect a microphone to the speaker to record their singing or playing; they can also connect instruments such as electronic keyboards and guitars to the speaker for music creation and practice. Simultaneously, the speaker can also connect to external storage devices (such as USB flash drives or external hard drives) via the USB sound card interface to directly play audio files stored on them, facilitating user management and playback of their music collections.

[0050] Please see Figure 13 In one embodiment, the speaker also includes a headphone / microphone input / output jack 11, which is connected to the main control chip 1. The headphone / microphone input / output jack 11 allows users to connect headphones or a microphone, enabling them to enjoy music or sing through the speaker without disturbing others.
