Abstract
The utility model discloses a miniature sound box provided with a telescopic resonance cavity. The miniature sound box comprises an audio line, an audio plug, a sound box upper shell, a sound box middle shell, a sound box lower shell, a loudspeaker, a circuit board, and a telescopic resonance cavity, wherein the miniature sound box provided with the telescopic resonance cavity is also provided with a transition piece, and the telescopic resonance cavity is connected with the sound box upper shell through the transition piece. According to the miniature sound box of the utility model, the transition piece is used to fix the telescopic resonance cavity and the sound box upper shell, so as to make the fixing between the telescopic resonance cavity and the sound box upper shell be more reliable.
Description
Technical field
The utility model relates to the miniature loudspeaker box field, more particularly, relates to a kind of miniature loudspeaker box with flexible resonator.
Background technology
In a kind of miniature loudspeaker box patent that I have applied for, number of patent application is 201220386162.X, described miniature loudspeaker box housing comprises audio amplifier upper casing, audio amplifier lower casing and flexible resonator, and an end of described flexible resonator is connected with the audio amplifier upper casing, and the other end is connected with the audio amplifier lower casing.Because flexible resonator is soft material, the plastics that voice box casing is normally relatively hard, direct-connected fixed form is unreliable between flexible resonator and the voice box casing.
The utility model content
Technical problem to be solved in the utility model provides a kind of flexible resonator and is connected reliable miniature loudspeaker box with flexible resonator with voice box casing.
The purpose of this utility model is achieved through the following technical solutions:
A kind of miniature loudspeaker box with flexible resonator, comprise tone frequency channel wire, audio jack, audio amplifier upper casing, audio amplifier lower casing, loudspeaker, circuit board and flexible resonator, described miniature loudspeaker box with flexible resonator also comprises transition piece, and described flexible resonator is connected with the audio amplifier upper casing by transition piece.
Preferably, described transition piece is circular, and described flexible resonator is cylindric, and described transition piece is enclosed within an end of described flexible resonator.Thereby circular transition piece and flexible resonator cylindraceous adapt fixing.
Preferably, the inside of described transition piece is provided with boss.Boss can block flexible resonator.
Preferably, the internal diameter of described transition piece is greater than the external diameter of flexible resonator sunk part, less than the external diameter of flexible resonator projection.The internal diameter of transition piece is greater than the external diameter of flexible resonator sunk part, less than the external diameter of flexible resonator projection, so that the flexible resonator of the better clamping of transition piece.
Preferably, described transition piece is provided with breach, and corresponding, the inside of described audio amplifier upper casing is provided with projection, and transition piece and audio amplifier upper casing can be fixed together by the mode of breach projection clamping.The fixed form of projection, breach is simple, reliable.
Preferably, the quantity of the breach of described transition piece is at least 2.Have at least 2 breach just can make the fixing reliable of transition piece and upper casing.
Preferably, described transition piece is provided with projection, and corresponding, the inside of described audio amplifier upper casing is provided with breach, and transition piece and audio amplifier upper casing can be fixed together by the mode of breach projection clamping.The fixed form of projection, breach is simple, reliable.
Preferably, the quantity of the projection of described transition piece is at least 2.Have at least 2 projections just can make the fixing reliable of transition piece and upper casing.
The utility model is owing to adopt transition piece to fix flexible resonator and audio amplifier upper casing, so that fixing between flexible resonator and the audio amplifier upper casing is more reliable.

Fig. 1 is the schematic diagram of the utility model miniature loudspeaker box transition piece;
Fig. 2 is the connection diagram of the utility model transition piece and flexible resonator;
Fig. 3 is the connection diagram of the utility model transition piece and audio amplifier upper casing.
Wherein: 1, transition piece; 2, boss; 3, breach; 4, flexible resonator; 5, projection; 6, audio amplifier upper casing.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.
Miniature loudspeaker box with flexible resonator of the present utility model, comprise tone frequency channel wire, audio jack, audio amplifier upper casing, audio amplifier lower casing, loudspeaker, circuit board and flexible resonator, described miniature loudspeaker box with flexible resonator also comprises transition piece, and described flexible resonator is connected with the audio amplifier upper casing by transition piece.
Embodiment one
As shown in Figures 1 and 2, described transition piece 1 is circular, and described flexible resonator 4 is cylindric, and described transition piece 1 is enclosed within an end of described flexible resonator 4.Thereby circular transition piece and flexible resonator cylindraceous adapt fixing.The inside of described transition piece 1 is provided with boss 2.Boss 2 can block flexible resonator 4.
The internal diameter of described transition piece 1 is greater than the external diameter of flexible resonator 4 sunk parts, less than the external diameter of flexible resonator 4 projections.The internal diameter of transition piece 1 is greater than the external diameter of flexible resonator 4 sunk parts, less than the external diameter of flexible resonator 4 projections, so that the flexible resonator of the better clamping of transition piece.
Described transition piece is provided with breach 3, and is corresponding, and the inside of described audio amplifier upper casing 6 is provided with projection 5, and transition piece 1 and audio amplifier upper casing 6 can be fixed together by the mode of breach projection clamping.The fixed form of projection, breach is simple, reliable.The quantity of the breach of described transition piece is 3.3 breach connect reliable.
Embodiment two
The difference of present embodiment and embodiment one is that described transition piece is provided with projection, and corresponding, the inside of described audio amplifier upper casing is provided with breach, and transition piece and audio amplifier upper casing can be fixed together by the mode of breach projection clamping.Other are all identical.
The utility model is owing to adopt transition piece to fix flexible resonator and audio amplifier upper casing, so that fixing between flexible resonator and the audio amplifier upper casing is more reliable.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that implementation of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection range of the present utility model.
