Technical field
This utility model embodiment relates to electronic information technical field, particularly relates to a kind of speaker and electronics
Equipment.
Background technology
Speaker is the abbreviation of loudspeaker unit, it is possible to is called for short unit, also known as " loudspeaker ", is that electroacoustic changes
Energy device, the most common in electroacoustic field.Speaker is a weaker assembly in electroacoustics system, but
It it is again a significant components.Audio frequency electric energy is by electromagnetism, piezoelectricity or electrostatic effect so that it is empty around shake film
Gas causes sound equipment.
Wherein, specifically, sound is issued by speaker shake film, and for consumer electronics product
For, owing to shake film spills direct sounding, the decay of sound is minimum, but affects attractive in appearance, the most unfavorable
In protection speaker shake film, therefore, it is difficult to be difficult on consumer electronics directly speaker be shaken
Film spills decay reducing sound etc..
Therefore, on consumer electronics product, a protective cover is often set outside speaker shake film, or
Person's housing, as protective cover, makes several simultaneously on this protective cover and goes out acoustic aperture, the sound that shake film sends
Issue through going out acoustic aperture, the external world passed to.
But going out the existence of acoustic aperture, cause high frequency loss big, sound details is lost.Simultaneously in order to take into account
Attractive in appearance and as far as possible retain details sound, and retain good high frequency characteristics avoid loss, it is necessary to
Contemplating the percent opening of acoustic aperture, in general, percent opening to be kept is the least, the most very
Difficulty is more than 20%, therefore, there is contradiction between percent opening and high frequency characteristics.
