Description

A kind of chair headrest with loud speaker
Technical field
The present invention relates to chair headrest technical fields, and in particular to a kind of chair headrest with loud speaker.
Background technology
Loud speaker is also known as loudspeaker, is used as electro-acoustic transducing device, is widely used among various stereo sets.With The demand of the development and client of science and technology, under the trend that electronic product is increasingly miniaturized, sight has equally been invested vapour by consumer On the vehicles such as vehicle, high ferro, aircraft.
By taking automobile as an example, when automobile on a highway when driving, it is interior for the vehicle that some soundproof effects are poor Noise can be very big, and acoustics caused by the common middle control loudspeaker of automobile can not override the noise outside vehicle, in this way Acoustics in automobile just performs practically no function, in addition, when car has multiple passengers, different passengers likes music The different or demand to loudspeaker of love is different, can not often meet the needs of each passenger simultaneously, is equipped in chair headrest as a result, The sounding headrest of loudspeaker device can meet the needs of passenger.
There is the chair headrest of the vehicles in China stringent regulation, but the existing chair headrest with loud speaker, Its structure is sufficiently complex, and the volume of loud speaker or loudspeaker is excessive, when accident occurs for the vehicles, in chair headrest The excessive head for being easy to throw away and hit passenger or driver of loudspeaker, it is more likely that cause mortal injury, therefore, can only will Loudspeaker volume reduces in proportion, but power reduces when volume-diminished, causes sound intensity inadequate, cannot meet the requirements, meanwhile, The distortion rate for increasing loud speaker greatly reduces the quality of sound, and therefore, there has been no a kind of safety, audio are good on the market Chair headrest occurs.
Invention content
It is an object of the invention to be directed to deficiency in the prior art, and it is good, safe to provide a kind of small volume, audio Chair headrest with loud speaker.
