Specific embodiment

The utility model embodiment is described further below in conjunction with the accompanying drawings：

As shown in the figure, the utility model provides a kind of shell speaker, including speaker body, in the speaker body appearance Face is equipped at least one membrane keyboard, which is inductance capacitance, when finger touches the membrane keyboard, can trigger primary triggering letter Number, at least one on ＆ off switch is set on speaker body surface, which uses as unlatching, closing and function switch, from And MCU is caused to enter different functional modes.MCU is HT66FV140, in the different compression numbers or duration by ＆ off switch During the signal of generation, the work of driving pin can be switched accordingly, so as to which its be made to complete functional mode switching.

And under different functional modes, MCU can then be carried out the trigger signal that membrane keyboard generates as different signals Identification, so that single membrane keyboard carries out different function switch.

As one embodiment, surface sets two on ＆ off switches, and two on ＆ off switches distinguish the switch S1 of ON/OFF in order to control With for playing the switch S2 of switching, two on ＆ off switches directly set upside or the circumferential direction of speaker body.

At least two groups of lamp groups are equipped in the speaker body, as one embodiment, the lamp group is two groups, if one group is The first lamp group 11 that extra dry white wine lamp is formed, another group of the second lamp group 12 formed for several color lamps.First, the first lamp group is as small night Lamp uses, and plays certain illumination functions, and the second lamp group realizes color then as atmosphere lamp by way of color lamp flicker Variation, so as to improve the whole atmosphere sense of speaker, and improve its interest.

Loudspeaker 13 are additionally provided in the speaker body, loudspeaker use HiFi Speakers, improve the acoustical quality of broadcasting.

The MCU includes single with switch S1 the first recognition units 3 being electrically connected and the second identification being electrically connected with switch S2 Member 4.

Wherein described first recognition unit includes long-press recognition unit and short-press recognition unit, that is, switchs S1 long-press 3 seconds Identification and the identification of switch S1 short-press.

Second recognition unit includes booting short-press recognition unit and shutdown short-press recognition unit, that is, switchs S2 and opening Machine pattern and the short-press of shutdown mode represent different function commands.

MCU is electrically connected respectively with the first recognition unit and the second recognition unit, obtains the knowledge that two recognition units are sent Level signal, and be compared with the signal of the function command of setting, the control signal for meeting current identification signal is sent, that is, is completed The function switch such as light switches or music switches；Identifying the long-press of control button S1 or control button S2 or short-press state, Then the control signal of corresponding states is exported respectively, and its internal signal compared is then previously entered and is set, it can basis Demand is modified.

The music of several midi formats built in the memory 6 enters MIDI music playing modes in the MCU, described The touch signal each time that membrane keyboard generates triggers the music sequence in one section of setting time respectively.

When in lamp light mode, light switching can be realized and be turned on and off function by touching membrane keyboard, in During playback of songs pattern, song switching can then be carried out by touching membrane keyboard, and when MCU enters piano music and plays pattern, it touches Membrane keyboard can cause the file of midi format that MCU goes identification to store, and will be in a manner of its music sequence by one group of setting It plays, realizes that the different function under different conditions switches by single membrane keyboard.

The MCU is also electrically connected with bluetooth module 5, the then neighbouring blue-tooth device of automatic search, such as mobile phone of bluetooth module 5 Mobile equipment plays music so as to carry out bluetooth connection.

The MCU1 is also electrically connected with playing indicating unit, the working station indicator of the broadcasting indicating unit report green with And red closing indicator light.

For detailed circuit referring to Fig. 2, Fig. 3, Fig. 4 and Fig. 5, wherein Fig. 2 is the circuit diagram of MCU, Fig. 3 for power supply unit with And the circuit diagram of indicating unit is played, Fig. 4 is the circuit diagram of membrane keyboard, and Fig. 5 is the circuit diagram of memory.Its Middle membrane keyboard is one or more, is set according to demand.

Its operating process is as follows：

Switch S1：

When long-press switchs S13 seconds, then speaker is switched on；

Booting plays function into piano music, and the more first piano musics of memory built-in touch be placed in shell table at this time The touch unit in face, you can to send out note by rhythm, touch the music sequence for once, sending out one group of setting；

And in open state, short-press switch S1, then bluetooth module unlatching bluetooth discovery function, and play what is connected automatically The music of mobile terminal；

In open state, long-press switchs S13 seconds, then turning-off sound box.

Switch S2：

In open state, short-press then enters next music, but in Bluetooth connected mode, which loses Effect；

In off-mode, short-press 1 time then turns on the white lamp of the first lamp group, then short-press 1 time, then opens the coloured silk of the second lamp group Lamp, third time short-press then close lamp group, while in arbitrary light status, and 3 seconds switch S2 of long-press are then turned on and off membrane keyboard Signal light control pattern, touch 1 time then can control the first lamp group white lamp, touch 2 times then enter the second lamp group color lamps, touch It then turns off the light for 3 times.

Embodiment is not construed as the limitation to the utility model, any spiritual improvements introduced based on the utility model, It should all be within the protection scope of the utility model.
