In addition, multifunction microwave oven also includes magnetron 17, well heater 19 and cooling fan 19.Wherein, magnetron 17 generates the microwave of cooking thing in the heating furnace chambers, and well heater 19 has roasts and function such as convection current the heated magnetron 17 of cooling fan 19 coolings, well heater 19 etc.The circuit of hummer 16 in the past as shown in Figure 2, it includes a hummer BZ1 who is connected with micro computer, the output resistance Ra that connects with hummer BZ1 is to the power supply unit Vcc of hummer BZ1 turn-on power.Above-mentioned formation be the closed-loop path of a hummer.
As shown in Figure 3, from the coordinate diagram of the micro computer R1 port of hummer frequency output as can be seen, in hummer in the past,, send single sound by the vibrations of sending out shake in the hummer if to the certain a frequency of the R1 of micro computer 13 port output.Utilizing the signal tone generating means of existing hummer is the single tone generating device that sends " serge " sound, and sound perception is dull and stiff, for the people that are familiar with multiple source of sound, feels dislike when often hearing this sound near noise.
Summary of the invention
Technical matters to be solved by this invention is, provides on a kind of connectivity port of micro computer to connect 2 above hummers, makes it send the multiple tone generating device and the method thereof of sound more than 2 kinds by the different separately frequency of port output that connects.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: one kind of multiple tone generating devices, be included as the press key input section of user input capability, control demonstrates the literal that will inform the user by the micro computer of the signal of press key input section input, by micro computer display, also comprise the double sound hummer, 2 hummers that are connected in parallel on the connectivity port of double sound hummer by micro computer constitute; When micro computer is connected with the double sound hummer by the connectivity port, export different separately frequencies simultaneously, make it send double sound to each connectivity port.
In the time will obtaining multiple sound effect, as long as increase the buzzer circuit quantity of required sound kind.
One kind of multiple sound method for generation, comprising the press key input section of promising user input capability, controlling in the device of the display formation that demonstrates the literal that to inform the user by the micro computer of the signal of press key input section input, by micro computer, when micro computer is connected with the double sound hummer by the connectivity port, export different separately frequencies simultaneously to each connectivity port, make it send double sound.
In the time will obtaining multiple sound effect, behind the hummer of the required sound kind of connection, export different separately frequencies simultaneously on the connectivity port of micro computer to each port, send multiple sound.
The invention has the beneficial effects as follows: after micro computer connects hummer in parallel more than 2, export different separately frequencies simultaneously, make it send double sound to the output port of micro computer; In the time will obtaining various sound, the hummer of right quantity is connected the output port of micro computer, can send various sound thus; Avoid the sound of the stiff dullness sent by the single sound of benchmark, and can send various sound and and twang, can improve user convenience.

Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
As shown in Figure 4, micro-wave oven mainly includes button operation portion 11, sensor part 12, micro computer 23, display part 15 and load driving part 14 usually.Wherein, button operation portion 11 is various cooking operation functions of input micro-wave oven; Sensor part 12 is to detect the humidity of food and temperature etc.; After micro computer 23 is stored automatic-cooking control program and various cooking data etc. in advance, control whole micro-wave oven according to the perceptual signal of the push button signalling of button operation portion 11 and sensor part 12 and cook; Display part 15 demonstrates various data according to the control of micro computer 23; Load driving part 14 makes various load driving such as magnetron 17, well heater 19, cooling fan 19 according to the control of micro computer 23.
Micro-wave oven of the present invention with the different place of the structure of sending single sound in the past is: the double sound hummer 26 that audio better sends double sound is installed.
