Fire fighting earphone

Abstract

This utility model relates to the field of communication equipment technology and provides a fire-fighting headset, including a main headset and a secondary headset. One end of the secondary headset is installed in the earcup on one side of the main headset via a snap-fit ​​structure. By adding a secondary headset to the main headset, an additional voice communication channel can be added, thus realizing the dual-channel intercom communication function of the fire-fighting headset. The main headset focuses on receiving global instructions from the fire command center, ensuring that firefighters can keep abreast of key information such as the fire spread and the allocation of rescue resources in real time. The secondary headset focuses on local on-site communication, allowing fire leaders to quickly issue immediate instructions to their team members, avoiding interference from global broadcasts to local operations. Instruction transmission is upgraded from "one-way indoctrination" to "two-way precise interaction," forming a closed-loop rescue system that links the global and local systems. At the same time, the dual-headset design can also reduce the risk of command failure caused by the interruption of a single communication link, ensuring the efficiency of on-site communication and flexibly responding to emergencies.

Description

Technical Field

[0001] This utility model belongs to the field of communication equipment technology, and in particular relates to a fire-fighting headset. Background Technology

[0002] In fire and rescue operations, fire headsets serve as crucial communication equipment, acting as a vital link between firefighters and the command center / team members to transmit information, directly impacting rescue efficiency and personnel safety. Their core function is to ensure clear transmission of voice signals in complex fire scenes, helping firefighters receive instructions and provide real-time feedback on the situation, thus supporting rescue decision-making.

[0003] Existing fire-fighting headsets are typically headband-style, with basic components including earcups, connecting rods, microphones, and connecting cables. The earcups contain speakers for audio reception, and the microphone extends to the mouth via the connecting rods to achieve voice acquisition and transmission. These headsets mainly operate through a single communication link, meaning they simultaneously receive broadcast instructions from the fire command center and facilitate on-site communication between team members. By switching channels or adjusting communication modes, they can meet the communication needs of different scenarios.

[0004] However, existing fire-fighting headsets have certain shortcomings in practical use: First, when transmitting through the same link, existing fire-fighting headsets are prone to signal superposition and interference, causing critical information to be lost. For example, when the command center broadcasts, real-time communication between team members must be interrupted, potentially delaying on-site rescue operations. Second, interference factors such as dense smoke, high temperatures, and equipment noise at the fire scene can cause signal attenuation or interruption of a single communication link. Once the link fails, firefighters will simultaneously lose contact with the command center and their teammates, greatly increasing the risk of rescue.

[0005] Therefore, in view of the above situation, there is an urgent need to develop a fire-fighting headset to overcome the shortcomings in current practical applications. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model embodiment is to provide a fire-fighting headset to solve the problems in the background technology mentioned above.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A fire-fighting headset includes a main headset, which is a type of over-ear headset. The main headset is equipped with an earcup, a main connecting rod, a main microphone, and a main connecting cable. The main microphone is mounted at the end of the main connecting rod. A main speaker is located inside the earcup. The headset also includes:

[0009] A secondary earphone, one end of which is installed inside the earcup on one side of the main earphone via a snap-fit ​​structure. The secondary earphone consists of a secondary speaker and an earphone assembly, with the secondary speaker located inside the earcup. The earphone assembly is equipped with a secondary connecting rod and a secondary microphone, with the secondary microphone installed at the tail end of the secondary connecting rod, and the secondary connecting rod located on one side of the main connecting rod.

[0010] As a further technical solution of this utility model, the earphone assembly includes an earphone base, an earphone top, a secondary connecting wire, a tactile switch, and a PCBA. The earphone base and the earphone top are connected as a whole. The earphone top is installed in the earcup via a snap-fit ​​structure. A secondary speaker is installed at one end of the earphone top, and a secondary connecting rod is installed at the other end of the earphone top. The secondary connecting wire and the tactile switch are respectively installed on the earphone base. A PCBA is installed between the earphone base and the earphone top. The PCBA is electrically connected to the secondary speaker, the secondary microphone, the secondary connecting wire, and the tactile switch.

[0011] As a further technical solution of this utility model, the headphone top seat adopts an arc-shaped structure, which is adapted to the shape and specifications of the ear cup.

[0012] As a further technical solution of this utility model, the snap-fit ​​structure adopts a U-shaped plate structure made of a flexible material.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By adding a secondary headset to the main headset, an additional voice communication channel can be added, enabling firefighters to achieve two-way communication by wearing fire headsets. The main headset focuses on receiving overall instructions from the fire command center, ensuring firefighters have real-time access to critical information such as the fire's spread and the allocation of rescue resources. The secondary headset focuses on local communication on-site, allowing fire leaders to quickly issue immediate instructions to their team members, avoiding interference from overall broadcasts on local operations. This makes the command hierarchy clearer, upgrading instruction transmission from "one-way indoctrination" to "two-way precise interaction," improving communication efficiency. Furthermore, the command center, with its overall view through the main headset, can combine the local dynamics transmitted through the secondary headset to make decisions more tailored to the actual situation on-site, forming a closed-loop rescue system that links the overall situation with local conditions.

[0015] Meanwhile, the dual-earphone dual-channel intercom communication design optimizes the reception sensitivity of the high-frequency broadcast signals of the command center in the main earphone, while the secondary earphone enhances the anti-noise capability of short-range communication between team members. Even when the signal is interfered with, the dual-channel communication can form a "redundant guarantee", reducing the risk of command failure caused by the interruption of a single communication link, ensuring the efficiency of on-site communication, flexibly responding to emergencies, and adapting to the needs of diverse rescue scenarios.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 4 As shown, a fire-fighting headset provided as an embodiment of this utility model includes a main headset 1, which is preferably a type of over-ear headset. The main headset 1 is equipped with an earcup 2, a main connecting rod, a main microphone, and a main connecting cable. The main microphone is installed at the end of the main connecting rod. A main speaker is disposed inside the earcup 2. The headset also includes:

[0025] The secondary earphone 3 is installed in the ear cup 2 on one side of the main earphone 1 via a snap-fit ​​structure 4. The secondary earphone 3 is composed of a secondary speaker 5 and an earphone assembly 6. The secondary speaker 5 is located inside the ear cup 2. The earphone assembly 6 is equipped with a secondary connecting rod 63 and a secondary microphone 64. The secondary microphone 64 is installed at the tail end of the secondary connecting rod 63, and the secondary connecting rod 63 is located on one side of the main connecting rod.

[0026] By adding a secondary earpiece 3 to the main earpiece 1, an additional voice communication channel can be added, enabling firefighters to achieve two-way communication by wearing fire headsets. The main earpiece 1 focuses on receiving overall instructions from the fire command center, ensuring that firefighters have real-time access to key information such as the fire's spread and the allocation of rescue resources. The secondary earpiece 3 focuses on local communication on-site, allowing fire leaders to quickly issue immediate instructions to their team members, avoiding interference from overall broadcasts on local operations, making the command hierarchy clearer, and upgrading instruction transmission from "one-way indoctrination" to "two-way precise interaction," thus improving communication efficiency. Furthermore, the command center, by grasping the overall situation through the main earpiece 1, can combine the local dynamics transmitted by the secondary earpiece 3 to make decisions that are more in line with the actual situation on-site, forming a closed-loop rescue system that links the overall situation with local conditions.

[0027] Meanwhile, the dual-earphone dual-channel intercom communication design optimizes the reception sensitivity of the high-frequency broadcast signal of the command center for the main earphone 1, while the secondary earphone 3 enhances the anti-noise capability of short-range communication between team members. Even when the signal is interfered with, the dual-channel communication can form a "redundant guarantee", reducing the risk of command failure caused by the interruption of a single communication link, ensuring the efficiency of on-site communication, flexibly responding to emergencies, and adapting to the needs of diverse rescue scenarios.

[0028] like Figures 1 to 4 As shown in the preferred embodiment of this utility model, the headphone assembly 6 includes a headphone base 61, a headphone top 62, a secondary connecting wire 65, a tactile switch 66, and a PCBA 67. The headphone base 61 and the headphone top 62 are connected as a whole. The headphone top 62 is installed in the earcup 2 through a snap-fit ​​structure 4. A secondary speaker 5 is installed at one end of the headphone top 62, and a secondary connecting rod 63 is installed at the other end of the headphone top 62. The secondary connecting wire 65 and the tactile switch 66 are respectively installed on the headphone base 61. The PCBA 67 is installed between the headphone base 61 and the headphone top 62. The PCBA 67 is electrically connected to the secondary speaker 5, the secondary microphone 64, the secondary connecting wire 65, and the tactile switch 66.

[0029] The communication status with the secondary earpiece 3 can be changed by touching switch 66, which allows firefighters to use both earpieces flexibly and avoid mutual interference.

[0030] like Figures 2 to 4 As shown, in a preferred embodiment of the present invention, the headphone top seat 62 preferably adopts an arc-shaped structure, and the arc-shaped structure can adapt to the shape and specifications of the ear cup 2, so that while the snap-fit ​​structure 4 fully fits inside the ear cup 2, the headphone top seat 62 will not affect the shape of the ear cup 2. This not only makes it convenient for users to wear quickly, but also avoids damage to the ear cup 2 and extends the service life of the ear cup 2.

[0031] like Figures 2 to 4 As shown, in a preferred embodiment of this utility model, the snap-fit ​​structure 4 is preferably a U-shaped plate structure made of a material with a certain degree of elasticity. In the initial state, the opening width of the snap-fit ​​structure 4 is greater than the inner diameter of the ear cup 2. During installation, the snap-fit ​​structure 4 is first squeezed so that its opening width is less than the inner diameter of the ear cup 2, which facilitates the snap-fit ​​structure 4 and the secondary speaker 5 to move into the ear cup 2. After the snap-fit ​​structure 4 and the secondary speaker 5 have moved to the designated position, the snap-fit ​​structure 4 is released. The snap-fit ​​structure 4 expands outward through its own elastic force and tightly abuts against the inner wall of the ear cup 2, thereby effectively fixing the secondary earphone 3.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
