Description
Technical field
The utility model relates to a kind of public address equipment, especially relates to a kind of portable loudspeaker.
Background technology
Public address equipment is usually in teaching, propaganda, and occasion such as small gatherings activity is used widely, the loudspeaker volume that has is bigger, carry inconvenience, so people have designed portable loudspeaker, as notification number for CN201523449 U discloses a kind of portable loudspeaker, casing comprises upper surface, lower surface and side, offer notch on the casing, casing inside is equipped with loud speaker, the guard that covers in the notch place also is installed on the casing, make the effect that amplifies even, be fit to guide interpreting, teaching, use in the propaganda, this loudspeaker need be handed, with loud speaker towards the audience, the long-time use allows user's fatigue, so people are provided with spring clip in the loudspeaker side, loudspeaker can be hung on the waistband, but spring clip is because improper use is fragile, or the use for a long time of the spring on the spring clip can follow the string, and makes the loudspeaker can not clamping or clip.And the above-mentioned disclosed loudspeaker loudspeaker that is direct intercommunication, there is not the function of displaying audio file, speech can make user's voice come to harm for a long time, also can be because of fatigue influence teaching or the effect of publicity.
Summary of the invention
The utility model mainly is fragile because of improper use at portable micropkonic spring clip, the use for a long time of spring on the spring clip can follow the string and can not displaying audio file etc. problem, a kind of portable loudspeaker that spring clip can clamping and can displaying audio file that is not provided with is provided.
The purpose of this utility model mainly is achieved by following proposal: a kind of portable loudspeaker, the chassis body bending is the U type, one side is the side of raising one's voice, one side is a nip side, middle interconnecting piece is divided into circular arc, the inboard of nip side is provided with fastener, and the wiring board in the U type casing is provided with the USBMP3 decompression machine, and the casing side is provided with the USB slot.The loudspeaker chassis body is made the U type, one side is the side of raising one's voice, one side is a nip side, and the fastener of projection is set in the inboard of nip side, making loudspeaker that spring clip need not be set like this can be stuck on the clothes easily, do not worry yet spring clip because of use exertin and damage or spring clip on spring because long-time use is followed the string etc. problem.The USBMP3 decompression machine is set on the wiring board in casing, other external equipments such as MP3 or mobile phone only need to connect the USB slot with data wire, can play the file of the MP3 format that is made into for the audio file of preparing in teaching or the guide's process or the related content that records in advance.
As preferably, the described side length of raising one's voice is greater than nip side length.The length of nip side is unsuitable long, can be clamped on clothes or the waistband to get final product.
As preferably, the gap of described raise one's voice side and nip side is 2-4mm.The gap of the side of raising one's voice and nip side can not be too big, otherwise do not have clamping action.
As preferably, described fastener is the strip projected parts parallel with the nip side top.On the medial surface of nip side, strip projected parts is set, makes raise one's voice gap smaller between side and the nip side of U type casing, more firm when loudspeaker is clamped on clothes or the waistband.
As preferably, described fastener is near the outward flange of casing inboard.
As preferably, described fastener height is 2mm.Nip side and the gap of raising one's voice between the side are 2-4mm, and the fastener height is made as 2mm, and making the gap of both sides is fit-state, makes the loudspeaker clamping more firm.
Therefore, the beneficial effects of the utility model are that spring clip need not be set, and can directly be stuck on clothes or the waistband, and are simple in structure, reliable, easy to use, can also directly amplify simultaneously, but displaying audio file again.
