[0026] In the current field of audio product design and development, with the increasing demand of consumers for product appearance and interactive experience, light effect function has gradually become an indispensable part. It not only can bring visual enjoyment to users and enhance the visual appeal of products, but also can reflect the state of the product or interact with the user to some extent, thereby improving the overall user experience.
[0027] In order to realize these colorful light effect effects, designers often need to find those main chip schemes with built-in energy acquisition and management functions. Such main chips can extract the energy value of the played audio and use the energy value for light effect display process. However, there are not many main chip schemes on the market that can provide such functions, and the selection range is relatively narrow.
[0028] Therefore, how to reduce the cost of the main chip and broaden the selection range while ensuring the lamp effect has become a problem to be solved in the current audio product design and development.
[0029] To solve the above problems, the present application provides a music energy acquisition device, please refer to Figure 1 Comprising:
[0030] The acquisition interface 101, the acquisition circuit 102, the acquisition unit 103 and the Bluetooth transmission unit 104.
[0031] The acquisition interface 101 is used to access the master chip, receive the audio signal transmitted by the master chip, and transmit the audio signal to the acquisition unit by the acquisition circuit; the acquisition interface is the connection bridge between the device and the master chip, responsible for receiving the audio signal transmitted by the master chip. The acquisition interface is designed as a standardized interface form, such as digital audio interface (such as I 2 S, PCM, etc.) or analog audio interface (such as 3.5mm earphone jack, RCA jack, etc.), to ensure compatibility with different types of master chips. The interface material should have good conductivity and durability, such as gold-plated or nickel-plated copper alloy, to reduce signal loss and improve connection stability.
[0032] The acquisition circuit 102 is a bridge connecting the acquisition interface and the acquisition unit, responsible for transmitting the received audio signal to the acquisition unit without loss. It uses high-quality audio cable, such as oxygen-free copper cable, to reduce signal attenuation and interference,
[0033] The acquisition unit 103 is used to receive the audio signal transmitted by the acquisition interface, and convert the audio signal into energy signal; the acquisition unit is the core component of the device, responsible for converting the audio signal into energy signal. The energy signal is used to represent the frequency, rhythm and amplitude of the music, etc. The specific energy signal conversion rule can be written in the acquisition unit in advance, such as how many decibels of volume corresponds to how much energy, which is not limited here.
[0034] The Bluetooth transmission unit 104 is used to transmit the energy signal to other devices. The Bluetooth transmission unit is responsible for transmitting the energy signal (some data or instructions based on audio signal analysis) converted by the acquisition unit to other devices. Other devices can be light devices, and can emit matching light effects based on the energy signal.
[0035] From the above technical solution can be seen, the embodiment of the present application has the following advantages: the present application provides a kind of music energy acquisition equipment, including: collection interface, collection circuit, acquisition unit and bluetooth transmission unit.The collection interface is used to access host chip, receives the audio signal transmitted by the host chip, and the audio signal is transmitted to the acquisition unit by the collection circuit;The acquisition unit is used to receive the audio signal transmitted by the collection interface, and the audio signal is converted into energy signal;The bluetooth transmission unit is used to transmit the energy signal to other devices.Based on the above content, the music energy acquisition equipment provided by the present application can widen the selection range of host chip, and does not necessarily have energy collection function, so that other devices can more easily obtain energy signal, and based on energy signal transmission to other devices (such as lamp effect device) needing to use energy signal, thereby improving the implementability of audio-lamp effect device.
[0036] Based on the above Figure 1 In the corresponding embodiment, the collection interface is a 3.5mm audio input port. The 3.5mm audio input port not only facilitates users to connect various audio devices, such as smartphones, MP3 players or notebook computers, but also ensures stable transmission of audio signals. Through this interface, the device can efficiently receive audio signals from the host chip or other audio sources, providing a basis for subsequent energy conversion and transmission processes.
[0037] Based on the above Figure 1 In the corresponding embodiment, the bluetooth transmission unit is a BLE Bluetooth chip plug. It is a Bluetooth technology specially designed for low-power wireless communication. The BLE Bluetooth chip plug not only has excellent communication stability and data transmission rate, but also can significantly reduce the energy consumption of the device while maintaining high efficiency. Through this unit, the device can transmit the energy signal (or related data) converted by the acquisition unit to other compatible devices, such as smartphones, tablets or smart home systems, in a wireless manner.
[0038] Based on the above Figure 1 In the corresponding embodiment, the acquisition unit has an anti-aliasing filter. The anti-aliasing filter plays a crucial role in the sampling process, as it can effectively filter out frequency components above half the sampling frequency, preventing aliasing after sampling, thereby ensuring the accuracy and clarity of the converted energy signal (or related data).
[0039] Based on the above Figure 1 In the corresponding embodiment, the acquisition unit has an energy value amplification circuit structure. The amplification circuit structure can refer to Figure 2 The specific amplification circuit structure can refer to the prior art, which will not be described here.
[0040] Based on the above Figure 1 Corresponding embodiments, optionally, the master chip belongs to the host, and the other device is a slave. Specifically, the whole system working process is that the music energy acquisition device serves the music-light effect system composed of the host and the slave, the host is used for playing music, the music energy acquisition device is used for receiving the audio signal, converting the energy value, and transmitting the energy value to the slave through Bluetooth, the slave is used for receiving the energy value, and displaying the corresponding light effect based on the energy value, the light effect changes with the energy value, and then the whole music and light effect correspond to each other.
[0041] The host can include an audio signal source interface / audio DSP, a power amplifier module, a loudspeaker module and the like. In actual use of the device, the connection relationship of each part can refer to Figure 3 That is, the acquisition interface is connected with the power amplifier module. The power amplifier module is connected with the loudspeaker module. The power amplifier module is connected with the audio signal source interface.
[0042] Based on the above Figure 1 Corresponding embodiments, optionally, the acquisition unit is further used for receiving the sound effect mode data transmitted by the master chip; and the Bluetooth transmission unit is further used for transmitting the sound effect mode data to other devices.
[0043] The acquisition unit is not only responsible for receiving the audio signal played by the host and converting it into an energy value, but also has the function of receiving the sound effect mode data transmitted by the master chip. The sound effect mode data is generated by the master chip according to the preset sound effect algorithm or the sound effect setting defined by the user, which contains information about the sound effect type, parameters and the like. The Bluetooth transmission unit also has the function of transmitting the sound effect mode data to other devices on the basis of the original function. This means that when the music energy acquisition device receives the sound effect mode data, it can also transmit it to other compatible devices through Bluetooth technology. In this way, other devices can adjust their sound effect settings according to the received sound effect mode data, so as to realize the sound effect matching with the music energy acquisition device.
[0044] The function of the slave has also been expanded accordingly. In addition to displaying the corresponding light effect according to the received energy value, the slave can now also adjust the presentation mode of the light effect according to the sound effect mode data. For example, when the sound effect mode data indicates a "rock" mode, the slave can adjust the brightness and flashing frequency of the light effect to better fit the atmosphere and rhythm of rock music. In actual implementation process, the setting and rules of the light effect mode data can be determined according to actual situation, and the specific place is not limited.
