Preferably, the interphone comprises a face shell, a power switch, a communication antenna, a call button, a charging socket and a circuit module, wherein the circuit module is located in the face shell.

Preferably, the circuit module includes circuit board, lithium cell and bee calling organ, lithium cell electric connection has the pilot lamp.

Preferably, fixing device includes the fixture block, the lower extreme fixedly connected with of fixture block extends the post, spacing hole has been seted up to the upper end of face-piece, and extends the post and insert and establish in spacing hole.

Preferably, the talk button is electrically connected to the microphone.

The utility model has the advantages that:

1. through setting up the fixture block, can establish the fixture block fixing clip on the connecting plate, then fix the intercom on the fixture block through the extension post of fixture block lower extreme to realize the combination use of helmet and intercom, solved the inconvenient problem of disconnect-type intercom carrying.

2. Compared with the common toy interphone, the interphone in the device uses an FM (frequency modulation) channel to transmit signals in a wireless mode, and the transmission bandwidth of the FM signal is wider than that of an AM (amplitude modulation) signal, so that the anti-interference performance is stronger, the conversation quality is better, and the signal transmission distance is farther especially in open areas.

3. Because the FM signal that the intercom used produces and receives relevant device volume less, so with the comparatively small and exquisite volume of intercom, improve the comfort level of intercom helmet, manufacturing cost is lower moreover, is convenient for realize large-scale production, has wide market prospect.

To sum up, the utility model discloses rational in infrastructure, the practicality is strong, uses intercom and toy helmet combination, has solved the intercom and has carried inconvenient problem, and the intercom adopts frequency modulation signal simultaneously, increases effective talk distance, improves speech quality.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1-9, an anti-interference mute intercom helmet, including helmet body 1 and intercom 4, two connecting plates 2 are installed through bolt symmetry in helmet body 1's both sides, goggles 3 are installed in the common rotation of the front side of two connecting plates 2, goggles 3 can protect the eye, eyes receive the injury when preventing children from playing, wherein the card is equipped with fixing device and links to each other with intercom 4 through fixing device on one connecting plate 2, fixedly on the intercom 4 is provided with microphone 5, intercom 4's send-receive signal is frequency modulation signal, frequency modulation signal's transmission bandwidth ratio width modulation signal's transmission bandwidth width, so its interference killing feature is stronger, speech quality is better, it is when open area, signal transmission's distance is farther.

The utility model discloses in, intercom 4 includes face-piece, switch 6, communication antenna 13, conversation button 14, charging socket 15 and circuit module, and circuit module is located the face-piece.

The circuit module includes circuit board 8, lithium cell 9 and bee calling organ 10, and lithium cell 9 electric connection has pilot lamp 7, and when lithium cell 9 electric quantity was sufficient, open switch 6, pilot lamp 7 can light automatically, and the person of facilitating the use judges whether intercom 4 is in normal operating condition.
