Abstract

The utility model discloses a portable sound structure which comprises a face casing and a base casing. The face casing and the base casing are installed in a matching mode, accommodating space is formed between the lower end surface of the face casing and the upper end of the base casing, a sound assembly, a backlight plate and a control plate assembly which are installed in a matching mode are arranged in the accommodating space, the sound assembly comprises a loudspeaker net and a loudspeaker which are installed in a matching mode, the sound assembly further comprises a silica gel sleeve, a magnetic core and a voice coil, the magnetic core and the voice coil are installed in the silica gel sleeve in a matching mode, the magnetic core is provided with a U-shaped ring groove, and the voice coil is installed in the U-shaped ring groove. According to the portable sound structure, the problems that replacement sound forces which reflect liveness in music can not be fully revealed and effects of played music are free of shock liveness and stereoscopic impression due to the fact that traditional portable sound structures are limited by sizes are solved.

Description

A kind of portable audio structure

Technical field

The utility model relates to a kind of acoustic structure, relates in particular to a kind of portable acoustic structure.

Background technology

Present portable audio mainly comprises portable signal source (CD/MP3) and portable speaker, usually all refer to portable speaker, be also referred to as Portable small sound box, most SD/U dish, three kinds of source of sound input sides of Linein of adopting, it has convenient small and exquisite, can carry, and does not need long tone frequency channel wire, do not need external power supply, the plurality of advantages such as multiple functional.

With the quickening pace of modern life, busy work brings many pressure to life, listening to the music no doubt is one of optimum method of releasing the pressure, but because environmental limit, the personage that handles official business of especially often going out, can sit down to listen just listens the soft music of releiving and becomes a kind of luxury, people travel outdoors, can listen music and see that beautiful scenery also is a kind of enjoyment, so the advantage of portable audio self is more and more welcome so that it more and more follows people's compatible the closing of life.Traditional portable audio structure is owing to be subjected to volume restrictions, to embody in the music presence for the representing not of sound dynamics, the music effect that therefore plays back lacks presence and the third dimension of the regret of shaking.

The utility model content

The technical problems to be solved in the utility model is in order to overcome technological deficiency recited above, a kind of portable audio structure to be provided.

In order to solve technical problem recited above, the utility model is taked following technical scheme:

A kind of portable audio structure, include and cooperate face-piece and the drain pan of installing, form accommodation space between described face-piece lower surface and the drain pan upper end, be mounted with in the described accommodation space and cooperate audible component, backlight and the control board assembly of installing, described audible component includes to cooperate speaker net, the loudspeaker of installing, described audible component also further to include silica gel sheath and cooperate and is installed in silica gel sheath interior magnetic core and voice coil loudspeaker voice coil.

Described magnetic core has the U-loop groove, and voice coil device is in described U-loop groove.

Described control board assembly further includes master control pcb board, battery, is provided with mains switch and function operating key on the described master control pcb board.

Be provided with storage card slot and USB interface on the described master control pcb board.
