Description

Composite microphone Technical Field

[0001] This patent belongs to the field of audio technology and recording equipment technology, especially microphone design and sound processing technology. Background Art

[0002] The design and use of recording equipment, particularly microphones, have a long history in audio technology. The core function of a microphone is to convert sound signals into electrical signals that can be captured and reproduced by audio equipment. While the basic operating principle of microphones is relatively simple, their designs and applications are extremely diverse, meeting a wide range of audio needs.

[0003] Common microphone types include dynamic, condenser, and bone conduction microphones. Dynamic and condenser microphones primarily generate electrical signals by capturing sound wave vibrations in the air, while bone conduction microphones generate electrical signals by capturing bone vibrations. Air conduction microphones (such as dynamic and condenser microphones) are widely used in various applications, such as music recording, public speaking, and television broadcasting. However, these microphones are often affected by ambient noise and may not clearly capture the target sound. Bone conduction microphones, on the other hand, directly capture sound signals transmitted through the bones, providing clearer sound in noisy environments. However, bone conduction microphones typically need to be placed close to the user's bones (such as the skull) to operate, which can be inconvenient in some situations. Technical issues

[0004] Current microphone technology typically captures only one type of sound, not both air-conducted and bone-conducted sound. Therefore, it's necessary to develop a new microphone design that can capture both air-conducted and bone-conducted sound simultaneously and synthesize them into a comprehensive sound signal. This is why I propose a hybrid microphone. The key technologies covered in this patent include capturing air-conducted sound, capturing bone-conducted sound, and synthesizing these two sounds. Technical Solutions

[0005] This utility model patent proposes a composite microphone that can simultaneously capture air-conducted sound and bone-conducted sound and synthesize the two sounds into a comprehensive sound signal.

[0006] Specifically, the main components of this patent include:

[0007] [Corrected 08 / 08 / 2023 per Rule 26] Air-conduction recording section (section "1" in the diagram): This section uses a common dynamic or condenser microphone to capture sound wave vibrations in the air. The air-conduction section can be designed to adapt to various acoustic environments, capturing clear, air-conducted sound.

[0008] [Corrected 08 / 08 / 2023 in accordance with Regulation 26] Bone conduction recording section (section "2" in the diagram): This section uses a special bone conduction microphone to capture sound signals transmitted through the bones. The bone conduction recording section can be designed to fit snugly against the user's bones (e.g., skull), thereby capturing clear bone conduction sound.

[0009] [Corrected 08 / 08 / 2023 in accordance with Rule 26] The processing center (section 3 in the diagram): This section is the core of the hybrid microphone. It receives the sound signals from the air-recording section and the bone-conduction recording section and combines them into a comprehensive sound signal. The processing center may include one or more sound processing algorithms, such as noise cancellation, sound enhancement, and sound synthesis.

[0010] [Corrected 08.08.2023 according to Rule 26] Optional output section (section "4" shown in the figure): The processed sound signal can be output to speakers for playback or to other devices for editing, research, etc. via wired or wireless output (such as Bluetooth). Beneficial effects

[0011] In our daily lives, people typically hear two types of their own voice: one transmitted through the air and the other transmitted through the bones. The blend of these two types of voices provides us with a comprehensive sound experience. This has important practical value for audio equipment manufacturers, audio technology researchers, music producers, and others. Modes for Carrying Out the Invention

[0012] The composite microphone mainly consists of the following four parts: air conduction recording part, bone conduction recording part, processing center, and optional output part.

[0013] Air conduction recording uses a dynamic or condenser microphone, depending on your needs. This microphone captures the vibrations of sound waves in the air and converts them into electrical signals. The position and angle of the microphone can be adjusted to optimally capture the sound.

[0014] Bone conduction recording: This uses a bone conduction microphone placed close to or in contact with the user's skull. The specific model can be selected based on actual needs. This part captures sound signals conducted through the bones and converts them into electrical signals.

[0015] Processing Center: The processing center is the core of the hybrid microphone. It receives the electrical signals from the air recording part and the bone conduction recording part, and uses sound processing algorithms such as noise cancellation, sound enhancement, and sound synthesis to combine these two sound signals into a comprehensive sound signal.

[0016] Optional output: Export audio signal data via wired or wireless (Bluetooth) transmission. You can configure the device to output mono or stereo audio, and output the synthesized audio signal or both. Industrial Applicability

[0017] The goal of this patent is to provide a new microphone design that offers users a comprehensive sound experience. By simultaneously capturing both air-conducted and bone-conducted sound, the hybrid microphone can more accurately reproduce the user's natural voice, thereby meeting their diverse audio needs. This invention has the potential to create a new generation of singers.
