# wireless microphone > microphone with circuitry to convert the audio signal to a radio signal **Wikidata**: [Q3123407](https://www.wikidata.org/wiki/Q3123407) **Wikipedia**: [English](https://en.wikipedia.org/wiki/Wireless_microphone) **Source**: https://4ort.xyz/entity/wireless-microphone ## Summary A wireless microphone is a microphone that contains circuitry to convert the captured audio signal into a radio signal for transmission. It uses wireless communication to send that radio signal to a receiver, allowing operation without a wired audio connection. ## Key Facts - A wireless microphone is a microphone with circuitry to convert the audio signal to a radio signal. - Primary functional mode: uses wireless communication to transmit audio. - Taxonomy: subclass of the microphone class (an acoustic-to-electric transducer that converts sound into an electrical signal). - Related classes: wireless microphone headset. - Common aliases: radio microphone; Microfono inalambrico; Microfono inalámbrico; Base micrófonica; Base microfonica; Micrófono inalambrico. - Wikimedia Commons image: https://commons.wikimedia.org/wiki/Special:FilePath/Shure_Wireless_Microphone_SM58.jpg. - Freebase identifier: /m/0c9sm1 (reference publication_date: 2013-10-28). - Wikidata description: "microphone with circuitry to convert the audio signal to a radio signal." - Wikipedia title: Wireless microphone (available in multiple languages including en, es, fr, de, ar, bn, ca, et, fa and commons). - Sitelink count on Wikidata: 16. - Commercial / database identifiers: amazon.com_browse_node 11974711; sciencedirect_topic_id computer-science/wireless-microphone; google_knowledge_graph_id /g/11h6t_kvk2; microsoft_academic_id_(discontinued) 2780642455. - Related product example: DJI Mic (listed as a related Thing / mic pack by DJI). ## FAQs ### Q: What is a wireless microphone? A: A wireless microphone is a microphone that converts the audio it captures into a radio signal and transmits that signal using wireless communication to a receiver, so it operates without a physical audio cable. ### Q: How does a wireless microphone transmit sound? A: It contains circuitry that converts the audio signal into a radio signal and then transmits that radio signal via wireless communication to a compatible receiver. ### Q: Are there other names for a wireless microphone? A: Yes. Common aliases include "radio microphone" and several language variants such as Microfono inalambrico and Microfono inalámbrico. ### Q: What are common variants or related types? A: One related class is the wireless microphone headset; product examples in the same category include items like the DJI Mic. ## Why It Matters Wireless microphones remove the need for a physical cable between the microphone and the receiver. By converting audio into a radio signal and sending it via wireless communication, they enable mobility for performers, presenters, broadcasters, and recording setups. This capability addresses logistical and safety concerns associated with cables, simplifies stage and field setups, and supports use cases where wired connections are impractical. Wireless microphones also form a distinct subclass within the broader microphone category and are represented across technical and commercial databases and marketplaces. Their presence in consumer, professional, and broadcast contexts is reflected by dedicated product lines (for example, wireless headset variants and mic packs like the DJI Mic) and by representation in technical literature and online knowledge resources. ## Notable For - Converting audio signals into radio signals for transmission rather than relying on a wired electrical output. - Being categorized as a distinct subclass of the general microphone class (an acoustic-to-electric transducer). - Having multiple common aliases across languages, including "radio microphone" and Spanish-language variants. - Appearing across reference and commercial systems (Wikidata/Wikipedia, Freebase, ScienceDirect, Google Knowledge Graph, Amazon browse node). - Supporting variants and related product forms such as wireless microphone headsets and consumer/professional mic packs (example: DJI Mic). ## Body ### Overview - Definition: A wireless microphone is a microphone with onboard circuitry that converts the captured audio signal into a radio signal. - Primary function: transmit audio wirelessly to a receiver using radio transmission. ### Technical function - Core operation: acoustic sound → electrical audio signal (microphone transduction) → circuitry converts audio signal into a radio signal → radio transmission (wireless communication). - The classification emphasizes transmission via radio as part of the device's circuitry and operation. ### Classification and identifiers - Subclass: microphone (an acoustic-to-electric transducer or sensor that converts sound into an electrical signal). - Related class: wireless microphone headset. - Wikidata description: "microphone with circuitry to convert the audio signal to a radio signal." - Freebase id: /m/0c9sm1 (reference publication_date: 2013-10-28). - Google Knowledge Graph id: /g/11h6t_kvk2. - Microsoft Academic id (discontinued): 2780642455. - ScienceDirect topic id: computer-science/wireless-microphone. - Amazon browse node: 11974711. - Reddit topic id: wireless_microphone. ### Names and media - Aliases: radio microphone; Microfono inalambrico; Microfono inalámbrico; Base micrófonica; Base microfonica; Micrófono inalambrico. - Wikimedia Commons image file reference: Shure Wireless Microphone SM58 image URL provided. ### Related items and variants - Wireless microphone headset is listed as a related class within the same domain. - Example related product: DJI Mic (a mic pack by DJI), cited as a related Thing. ### Documentation and presence - Wikipedia title: "Wireless microphone" with multi-language presence (languages include en, es, fr, de, ar, bn, ca, et, fa and commons). - Sitelink count on Wikidata: 16, indicating multiple linked language pages and references. ## References 1.
