Abstract
Description
Technical Field
[0001] This utility model relates to the field of headphone technology, and in particular to a headphone that can be used for karaoke. Background Technology
[0002] Headphones, as an indispensable electronic device in modern daily life, are typically used in conjunction with smartphones and other smart devices. By transmitting audio signals directly to the ear canal, they effectively isolate external noise interference and prevent the sound from disturbing others. Currently, most headphone products on the market integrate the microphone into the in-line control, requiring users to hold the microphone close to their mouth to ensure clear sound pickup, or fix the microphone externally to the in-line control. This can feel cumbersome when the microphone is not needed.
[0003] Meanwhile, existing headphones with microphones generally suffer from poor separation between accompaniment and vocals, making it difficult for users to accurately monitor their own voices when singing karaoke. In addition, excessive audio signal transmission delay causes the in-ear sound to be out of sync with the actual singing, affecting the singing experience. Utility Model Content
[0004] Based on this, and to address the shortcomings of existing technologies, a new type of headphone is provided.
[0005] An earphone includes a left speaker unit, a right speaker unit, a microphone assembly, and an earphone control box. The left speaker unit is connected to the earphone control box via a left audio cable, the right speaker unit is connected to the earphone control box via a right audio cable, the microphone assembly is pluggably connected to the earphone control box, and the earphone control box is connected to a smart device.
[0006] In some embodiments, the device also includes a male microphone audio cable connector and a female microphone audio cable connector, wherein the male microphone audio cable connector is connected to the female microphone audio cable connector, the male microphone audio cable connector is connected to the headphone control box, and the female microphone audio cable connector is connected to the microphone assembly.
[0007] In some embodiments, the microphone audio line female connector is connected to the microphone assembly via a microphone audio line.
[0008] In some embodiments, the headphone control box includes a digital signal processing unit. The input terminal of the digital signal processing unit is electrically connected to the smart device, and the output terminal of the digital signal processing unit is electrically connected to the left speaker unit and the right speaker unit. The digital signal processing unit is used to receive digital audio signals from the smart device, decode the digital audio signals into independent left channel analog signals and right channel analog signals, transmit the left channel analog signal to the left speaker unit, and transmit the right channel analog signal to the right speaker unit.
[0009] In some embodiments, the headphone control box includes a microphone signal processing unit. The input terminal of the microphone signal processing unit is electrically connected to the microphone assembly, and the output terminal of the microphone signal processing unit is electrically connected to the smart device. The microphone signal processing unit is used to perform noise reduction, gain adjustment, analog-to-digital conversion, and / or sound effect processing on the analog signal input from the microphone assembly, and transmit the processed signal to the smart device.
[0010] In some embodiments, the headphone control box includes a power distribution unit. The input terminal of the power distribution unit is electrically connected to the smart device, and the output terminal of the power distribution unit is electrically connected to the left sound unit, the right sound unit, and the microphone assembly. The power distribution unit is used to distribute power to the left sound unit, the right sound unit, and the microphone assembly.
[0011] In some embodiments, a control module is provided outside the headphone control box.
[0012] In some embodiments, the device further includes a left ear hook structure and a right ear hook structure, which are arc-shaped. The left ear hook structure is fitted over the left audio cable and connected to the left sound unit. The right ear hook structure is fitted over the right audio cable and connected to the right sound unit.
[0013] In some embodiments, the headphone control box connects to the smart device via a Type-C interface.
[0014] This invention relates to an earphone component that uses a pluggable design to install the microphone assembly into the earphone body. Users can choose to install or remove the microphone according to their needs, allowing for more precise sound pickup when the microphone is needed and eliminating any sense of bulk when the microphone is not in use, making it a multi-functional device. By using an earphone control box to perform noise reduction, gain adjustment, analog-to-digital conversion, and sound effect processing on the microphone input signal, it can enhance the vocal frequency band, suppress ambient noise and vocal frequencies in accompaniment, and avoid masking effects. At the same time, it decodes the digital audio signal input from smart devices into independent analog signals for the left and right channels, which not only accurately reproduces the audio signal and presents a stereo sound field effect, but also accurately and quickly transmits in-ear monitoring sound, improving the singing experience.
