Abstract
The utility model relates to a helmet, concretely to a hearing-aid helmet, which resolves the question in the conventional technology that the crash helmet is not good for sound penetrating. The helmet comprises a helmet body, and both sides of the helmet body are provided with loudspeakers, and two microphones are connected to the outside of the helmet corresponding to the loudspeakers through a control circuit. The hearing-aid helmet of the utility model additionally increases loudspeakers and microphones inside and outside the traditional helmet, with reasonable design and simple structure. The acceptability of drivers for circumambient sound signal during driving is enhanced, which is helpful for safe driving.
Description
Technical field
The utility model relates to a kind of helmet, is specially a kind of hearing aid helmet.
Background technology
The Motor-cyclist is on the run must the safe wearing helmet, though traditional helmet is very solid, sealing is fine.Structural design diminishes people's the visual field like this, and can weaken the external sound signal and import people's ear into, particularly in the process that motorcycle is advanced at a high speed, if can not accurately distinguish extraneous particularly after one's death with the voice signal of side, might influence traffic safety.
Summary of the invention
The utility model is unfavorable for the problem that sound penetrates and a kind of hearing aid helmet is provided in order to solve the crash helmet that exists in the prior art.
The utility model is realized that by following technical scheme a kind of hearing aid helmet comprises the helmet body, and the helmet body is provided with loudspeaker in the both sides, and the corresponding external side of helmet is connected with microphone by control circuit.
After putting on the helmet described in the utility model, voice signal around in the process of travelling is collected by microphone, pass to after amplifying by control circuit then in the loudspeaker in the helmet and play, the driver just can very clearly hear all sound that send on the road, to guarantee safe driving.
Compared with prior art, the utility model has installed microphone and loudspeaker respectively additional inside and outside traditional helmet, reasonable in design, simple in structure, can strengthen driver's ability to accept to the peripheral sound signal in driving process, helps safe driving.

The specific embodiment
A kind of hearing aid helmet comprises helmet body 1, and the helmet body is provided with loudspeaker 2 in the both sides, and the corresponding external side of helmet is connected with microphone 5 by control circuit.
Shown in 1,2 in accompanying drawing, position relative and people's ear is equipped with loudspeaker 2 in the helmet body 1 of the helmet, the loudspeaker rear portion is connected with sleeve 9, is inserted with double-screw bolt 13 in the sleeve, and sleeve passes the helmet body, the helmet body 1 outer lid 10 that is provided with, the rear portion of sleeve is connected with spiral cover 12 on being connected lid 10 by spring 11, and cross-under has microphone 5 and gauge tap 6 on the lid, and lid is built-in with control box 7, be provided with control circuit in the control box, control box 7 is communicated with by lead with microphone 5 and loudspeaker 2 respectively.
Sleeve passes the helmet body, drives the relative position that loudspeaker 2 is regulated in double-screw bolt 13 rotations by rotating spiral cover 12, and the effect of spring can make and keep the tensioning stable state between loudspeaker 2 and the helmet body.
The microphone 5 outer sponge covers 3 that are with.The sponge cover can make people's ear feel more comfortable.
Control circuit comprises pickup amplifying circuit, audio amplification output circuit, power circuit.
The pickup amplifying circuit comprises microphone BM1, BM2, transistor V, and resistor R 1～R2 and capacitor C 1, C2 forms.
Audio amplification output circuit comprises volume potentiometer RP, resistance R 5, R6, and capacitor C3～C7, audio frequency amplify chip IC and loudspeaker BL1, BL2.
Power circuit comprises battery GB, power switch S, filter condenser C8, current-limiting resistor R7 and power supply indication Light-Emitting Diode VL.
Microphone BM1, BM2 are connected with the base stage of transistor V, and the colelctor electrode of transistor V amplifies the chip IC input with audio frequency and is connected, and the output that audio frequency amplifies chip IC is connected with loudspeaker BL1, BL2.
After connecting power switch S, Light-Emitting Diode VL lights, complete machine energising work.Microphone BM1, BM2 convert the voice signal that picks up to the signal of telecommunication after audio frequency amplifies the ground level that chip C1 is coupled to transistor V, and this signal, drives BL1, BL2 and sounds after control of RP volume and the IC power amplification through the preposition amplification of transistor V.
