Description

Hard hat hands-free broadcasting device

technical field

The utility model relates to a hands-free broadcasting device for a safety helmet, in particular to a device which is applied to a safety helmet and has the functions of broadcasting and voice dialogue. the

Background technique

When riding a motorcycle, in order to protect the head of the rider, it is necessary to wear a safety helmet. However, when wearing a safety helmet, there is often a need to listen to music or answer (make) calls. It is common to use wired headsets or Bluetooth headsets to listen to music or answer (dial) calls through wired or wireless transmission methods. In the case of wired headsets, it is necessary to connect external smart devices through transmission lines (or smart phones), so there are disadvantages such as the transmission line may be entangled with foreign objects or the inconvenience of storage. Although the Bluetooth headset is transmitted wirelessly, it is more convenient than the wired headset, but the Bluetooth headset still needs to be worn on the ear. , for the user, not only is there a fear of falling off when riding a motorcycle, but it may cause discomfort if worn for a long time, and because it needs to be worn on the ear, so when listening to music or answering (dialing) When making a phone call, it is often impossible to hear the outside world such as the rear horn or other warning sounds at the same time, which has safety concerns. Moreover, most general Bluetooth headsets are only compatible with specific smart devices (or smart phones), so Special attention must be paid when purchasing, as the above-mentioned deficiencies are actually deficiencies that users often criticize. the

Therefore, how to improve the above missing problem is the technical difficulty that the inventor of this case wants to solve. the

Detailed ways

Please refer to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Fig. 6, which are three-dimensional appearance diagrams, three-dimensional exploded diagrams, preferred embodiment diagrams and further embodiment diagrams of the present utility model, from the figure It can be clearly seen that the hands-free broadcasting device 1 includes:

A base 2 is provided with a sticker 21, a charging connection port 22 and a button 23 on its outer side, and a power supply element 6 is arranged inside;

A resonant horn 3, set in the base 2;

A near-field wireless communication module 4, set in the base 2, the near-field wireless communication module 4 is one of NFC (Near Field Communication) or RF ID (Radio Frequency I Identification n);

A bluetooth communication module 41, arranged in the base 2;

A radio element 5 is arranged on the outer side of the base 2;

The hands-free broadcasting device 1 of this invention is mainly applied to the safety helmet 7. When in use, first set it on the outer surface of the safety helmet 7 through the attachment 21 on one side of the base 2, and connect it to a device such as a smart phone or a tablet. Or the handheld smart device 8 of PDA is close to the hands-free broadcasting device 1. At this time, the near-field wireless communication module 4 in the hands-free broadcasting device 1 will immediately connect to the handheld smart device 8, and automatically receive the hand-held The wireless signal sent by the smart device 8, when playing music on the smart device 8, drives the resonant speaker 3 to move, resonates the speaker 3 and uses the entire helmet 7 as a resonator, so the wearer can pass through the safety hat 7 to listen to the music played by the handheld smart device 8, and when the handheld smart device 8 calls, the user only needs to press the button 23 on the hands-free broadcasting device 1 to switch to the action of making a voice call, and through The radio element 5 carries out voice communication with the caller;

Based on the above, when the handheld smart device 8 receives a call, the music stops immediately and simultaneously switches to prepare to play the voice of the caller. After the user presses the button 23, he can hear the caller's voice, and the sound receiver 5 communicates with the caller. Voice communication, basically, the wireless signal transmitted by the hand-held smart device 8 and the voice uttered by the user are sent and received through the Bluetooth communication module 41, and the near-field wireless communication module 4 is established with the hand-held smart device 8 For connection, the reason why the near-field wireless communication module 4 is used to connect the handheld smart device 8 is mainly because the near-field wireless communication module 4 can adapt to most handheld smart devices 8, and the speed of connecting the handheld smart device 8 is relatively fast. quick;

In order to enable the sound receiving element 5 to receive the wearer's voice smoothly, the sound receiving element 5 can basically be designed as a soft and bendable flexible pipe as shown in the figure, so that the sound receiving element 5 can be adjusted to The best sound-receiving position, or as shown in the further embodiment diagram of Fig. 6, the sound-receiving element 5 is designed as a pull wire, and the sound-receiving element 5 is directly arranged inside the helmet 7 and close to the mouth of the wearer. So that the sound-receiving element 5 can smoothly receive the voice of the wearer, in addition, a charging connection port 22 is provided on the outside of the base 2, through which the charging connection port 22 can be used to power the power supply element in the base 2 6 the action of charging;

Since the hands-free broadcasting device 1 mainly broadcasts sound through the resonant horn 3 using the helmet 7 as a resonant body, the type of the helmet 7 is basically as shown in the figure. When the user wears the helmet, After 7, the 7 type of safety helmet that can cover the ears works best;

It is also worth mentioning that the hands-free broadcasting device 1 of this creation can not only provide the wearer with voice calls and voice communication functions, but also allow the same locomotive to Two-way voice communication function for two-way riders;

To sum up, the hands-free broadcasting device 1 of this invention not only quickly connects with the hand-held smart device 8 through the near-field wireless communication module 4, but also broadcasts sound through the resonant speaker 3 using the helmet 7 as a resonant body. Compared with the traditional way of using wired earphones or bluetooth earphones, in addition to the user not needing to wear them on the ears to increase comfort, there is no need for speakers and the sound is broadcast through the entire helmet 7, so that music and voice can be heard more clearly. Moreover, the outside world such as rear horns or other warning sounds can be heard at the same time, thereby greatly improving the safety of riding a motorcycle. Furthermore, through the design of the attachment 21, the hands-free broadcasting device 1 can also be applied to various specifications of safety vehicles. Cap 7, therefore, the hands-free broadcasting device 1 of this creation not only improves the safety of riding a motorcycle for users, but also increases the convenience for users to listen to music or answer (make) calls when riding a motorcycle . the

The above-mentioned embodiment is used to illustrate a preferred embodiment of this creation, and is not intended to limit the scope of this creation. Anyone who is familiar with this art can do some things without departing from the spirit and scope of this creation. Changes and retouching, so the scope of protection of this creation should be defined by the scope of the attached patent application. the
