Headset Connecting Wire Antenna for FM Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable wireless communications devices face challenges in receiving FM signals due to the impracticality of embedding long antennas, which are necessary for adequate signal reception, leading to bulkiness and reduced convenience when external antennas are used.
Innovation Solution
A headset system with a conductive connecting piece that functions as an antenna, allowing for wireless multimedia transmission and reception, including FM signals, without the need for external wires, by integrating the antenna within the headset's connecting wire, enabling efficient signal reception without increasing device bulk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a long antenna is embedded in the wireless communications device to receive FM signals, then signal reception performance is improved, but device size and bulk increase
Solution Approach 1:
The patent extracts the antenna function from the main device body and relocates it to the headset wire. The wire connecting the headset to the device serves as the antenna element, allowing the device to receive FM signals without embedding a long antenna in its housing. This resolves the contradiction by removing the bulk-causing component while maintaining reception capability.
Solution Approach 2:
The headset wire acts as an intermediary element that performs the antenna function. Instead of the device housing serving as the antenna structure, the connecting wire between device and headset fulfills this role, enabling FM signal reception without increasing device volume.
2Reliability
If an external antenna is attached to the wireless communications device to receive FM signals, then signal reception performance is improved, but device convenience and portability are reduced
Solution Approach 1:
The patent merges the antenna function with the existing headset connection wire. Rather than adding a separate external antenna that would compromise convenience, the solution combines the antenna role with the wire already necessary for audio transmission, maintaining device portability while enabling FM reception.
Solution Approach 2:
The headset wire serves multiple functions: it provides the electrical connection for audio signals and simultaneously functions as the antenna for FM signal reception. This multi-functionality eliminates the need for separate components, preserving convenience while achieving reception capability.
3Volume of moving object
If a short antenna is used in the wireless communications device, then device size is reduced, but signal reception performance deteriorates
Solution Approach 1:
The patent extends the antenna element from the three-dimensional device housing into the spatial dimension of the headset wire. By utilizing the wire's length (which can be several feet) as the antenna element, the solution achieves the necessary antenna length for FM reception without increasing the device's physical dimensions.

AI summary
System and method for wirelessly providing multimedia. A system includes a headset and a wireless communications device. The wireless communications device controls the operation of the headset with transmissions over a first wireless network. The headset includes a first ear piece, a second ear piece, and a connecting piece. The first ear piece has a first speaker, a first network interface to send and receive transmissions over the first wireless network, a second network interface to receive transmissions over a second wireless network, and a connecting piece. The connecting piece is coupled between the first ear piece and the second ear piece. The connecting piece includes a wire to electrically couple the second ear piece, the first ear piece, and the second network interface and to receive transmissions over the second wireless network. The wire may be made to any length since it may be embedded inside the connecting piece.
