Description

Technical Field

[0001] This utility model relates to the technical field of microphones, and in particular to a detachable microphone. Background Technology

[0002] Microphones are an important component of various audio amplification systems. As a key audio-to-electrical conversion device, microphones perform the basic function of converting acoustic signals into electrical signals. Traditional microphones typically include dynamic and condenser types. Their output signals often need to go through a series of signal processing steps such as preamplification, filtering, equalization, and analog-to-digital conversion before being amplified by a power amplifier to finally drive the speaker to reproduce the sound. For ease of use, pen microphones usually have a clip on the back, allowing them to be easily clipped to the body for use at any time.

[0003] However, in the existing technology, the back clip of most pen microphones is an integrated structure with the main body of the pen microphone. Once the back clip breaks, it cannot be replaced and will lose its clamping function, making the pen microphone less convenient to use. In summary, the existing pen microphones still have certain limitations in the structural design of the back clip and need further improvement. Utility Model Content

[0023] like Figures 1-11 As shown in the figure, an embodiment of the present invention provides a detachable microphone, comprising: The microphone body comprises a first housing 11 and a second housing 12, which are connected to form an installation cavity. The outer side of the second housing 12 has a protruding first connecting part 121. The control component is used to control the various parts of the microphone and is located inside the installation cavity. The clamping structure 3 includes a second connecting part 31 for connecting the microphone body and a first clamping part 32 for fixing the microphone. The first clamping part 32 is connected to the second connecting part 31, and the second connecting part 31 is detachably connected to the first connecting part 121. The first clamping part 32 and the microphone body form a clamping position. The clamping structure 3 clamps common clamping objects (such as collars and backpack straps) in the clamping position.

[0024] In this embodiment of the present invention, the first connecting part 121 and the body of the second housing 12 are manufactured by an integral molding process, preferably using ABS (acrylonitrile-butadiene-styrene copolymer) + PC (polycarbonate) engineering plastic, which ensures the stability and mechanical strength of the overall structure of the second housing 12 and improves the connection stability between the first connecting part 121 and the second connecting part 31.

[0025] Preferably, the clamping structure 3 is made of one of PA (polyamide), POM (polyoxymethylene, acetal) or PEEK (polyetheretherketone), with PA (polyamide) being the preferred material, so that the second connecting part 31 has both excellent toughness and fatigue resistance; at the same time, the dimensional accuracy and durability of the second connecting part 31 are effectively guaranteed by the one-piece molding process, thereby improving the convenience and stability of the connection between the second connecting part 31 and the first connecting part 121.

[0026] The clamping structure 3 of this utility model adopts a detachable structural design, making it a detachable module independent of the microphone body. This allows the second connecting part 31 to form a detachable connection with the first connecting part 121 protruding on the outer side of the second housing 12. When the first clamping part 32 breaks due to frequent clamping or accidental drops, the user does not need to scrap the entire microphone; simply replacing the clamping structure 3 will restore its clamping function, improving the convenience of the microphone during use and extending its service life. Furthermore, the detachable design of the clamping structure 3 allows the user to install and remove it as needed, adapting to various scenarios such as handheld and worn microphones, thus improving the microphone's flexibility and enhancing the user experience.

[0029] In this embodiment of the utility model, the first guide part 311 and the first limiting part 312 are disposed opposite to each other on the second connecting part 31. The structure design of guiding and locking is adopted to avoid damage to the components of the second connecting part 31 due to blind force.
