Description

Externally connecting level display of sounder

The utility model relates to a kind of sounder lever indicator.

As everyone knows, the lever indicator of sounder can play a kind of attractive in appearance and adjusting atmosphere when playing back music, but all at present lever indicators all are internal connecting types, and they and sounder closely link together, and have a shell.Because be subjected to the restriction of sounder outward appearance, their general volumes are very little, form is also very dull, can not put them more suitably local at home with owner's hobby.Also have some sounders, particularly walkman in addition, they just do not have lever indicator at all.

The purpose of this utility model just provides a kind of sounder circumscribed lever indicator, this display is a separate component, can link to each other with existing various sounders with special plug by lead, for the sounder that does not have display increases Presentation Function, show that for existing the sound equipment of device provides display bigger, more attractive in appearance.It has very big randomness and interchangeability, can be placed on family expenses and land the top of sound equipment, can hang on the wall, can be placed in the show window of elaboration cabinet, also can connect together with family expenses karaoke television or electronic organ.It also can do very for a short time, link to each other with walkman in being placed on pocket, and display can be on user's the hem.

The utility model is the same with common lever indicator to be comprised outside display and the apparent control circuit, also comprises voice band line, power circuit and plug three parts, and wherein display has a shell that is independent of sounder.As Fig. 1, display links to each other with sounder with plug by control circuit, voice band line; Power circuit links to each other with power supply, for display provides energy.

Power circuit of the present utility model has two kinds of forms, and a kind of is in external lever indicator shell battery to be set, and links to each other with display by power circuit.Another kind is to draw lead in shell, links to each other with the sound equipment internal power supply by plug, and this form sees embodiment 2 for details.

Voice band line of the present utility model also has two kinds of forms, and a kind of is ad hoc one external lever indicator tone currents output plughole on sounder, links to each other with display with voice band line by plug.Another kind is under the situation that does not influence former machine service behaviour, draws tone currents with plug from the earphone jack of sounder, is transported in the circumscribed lever indicator by voice band line, and this form sees embodiment 1 for details.

Display element of the present utility model is identical with existing lever indicator with the demonstration control circuit, for known technology, is not repeated.

Compared with prior art, the utility model can make sounder increase the level Presentation Function under the situation of former sounder being made little change or not making any changes, and it has simple in structure, dependable performance, advantage easy to implement.

The drawing explanation:

Fig. 1 is the utility model internal structure block diagram;

Fig. 2 is embodiment 1 appearance assumption diagram;

Fig. 3 is the audio jack fundamental diagram;

Fig. 4 is embodiment 2 appearance assumption diagrams;

Fig. 5 is embodiment 2 circuit diagrams;

Fig. 6 is embodiment 3 appearance assumption diagrams.

Introduce three embodiment of the present utility model below in conjunction with accompanying drawing.

As Fig. 2, embodiment 1 is a multifunctional domestic circumscribed lever indicator, and (1) is display, has 14 display element piano types and arranges; (2) be shell, organic plastics is made; (3) be voice band line, it adopts second kind of form of aforementioned voice band line; (5) be special audio jack; (7) for hook,, also can hang on the wall so that lever indicator can be put on the table; The present embodiment power circuit adopts first kind of form of aforementioned power source circuit, puts battery in shell (2).

As Fig. 3 is the fundamental diagram of audio jack (5).As 5a, the earphone socket (13) of existing sounder is not when inserting headset plug, and movable contact spring (9) touches mutually with static contact spring piece (8), and sounder provides tone currents by (9) and (8) to loud speaker.As Fig. 5 b, after headset plug (11) inserted, movable contact spring (9) was pushed up from static contact spring piece (8), loud speaker stops pronunciation, sounder makes the earphone pronunciation by plug (11), and present embodiment has designed audio jack (5) according to the above-mentioned operation principle of earphone socket.This plug is shorter than headset plug (11), after inserting jack (13), its can touch mutually and not with its jack-up with movable contact spring (9), so dynamic and static reed still keeps in touch, so the sound equipment function under the situation that loud speaker is still worked, is passed to external lever indicator with tone currents by plug (5).

In the utility model, the preceding elastic electric conductor (10) (as metal spring) that connects of plug (5), after plug (5) inserts, elastic electric conductor (10) is compressed, movable contact spring (9) is separated with static contact spring piece (8), plug (5) is contacted well, to be suitable for different sounders with movable contact spring (10).

As Fig. 4, embodiment 2 is a walkman circumscribed lever indicator, and it is fixed on the line (16) of earphone (15), and its voice band line is in parallel with the voice band line of earphone, and links to each other with the earphone jack of sounder (14) by headset plug (5a).Put on earphone when listening to the music as people this moment, and this lever indicator just is positioned at user's chest locations, can play decoration function, and links up with (7) on it, can make lever indicator not on user's the hem.(4) are power circuit among the figure, and it adopts second kind of form of aforementioned power source circuit, links to each other with the external power supply jack of sounder by plug (6).The structure of plug (6) is identical with plug (5) among Fig. 3 with operation principle.External power supply jack originally is behind plug (6), because its unique texture, the sound reed is not separated, so the sound equipment self-contained battery both can make sounder work, can pass through plug (6) and power circuit (4) again and give display (1) power supply.

Display casing in the present embodiment (2) is square, and in other embodiments, it can be various ways such as heart, pentalpha or crux.

Fig. 5 is the circuit diagram of embodiment 2, wherein power circuit (4) and voice band line (3) shared grounding line (17).Wherein C1 is 4.7u, and R1 is 10K, and R2 is 4.3K, and D1-5 is a light-emitting diode, and the IC model is TA7666P.(12) be the volume pause switch, the pause switch or the volume knob of existing earphone all are loaded on the earphone (15), be not easy to people's operation, present embodiment places shell (2) (as Fig. 4) to it, its control end stretches out outside the shell (2) by the hole on the shell, because the lever indicator of present embodiment just is positioned at user's chest locations, so pause switch (12) very is beneficial to operation.

As Fig. 6, embodiment 3 is for having the external little audio amplifier of walkman of lever indicator, and display (1) has a shell that is independent of sounder with external speaker (18).Its voice band line (3) links to each other with sounder by audio amplifier plug (5b), and power circuit (4) links to each other with the sounder external power supply jack by plug (6), and its operation principle is described identical with embodiment 2, is not repeated.
