Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
The utility model proposes a kind of wireless cascade sound equipment and system.As shown in Figure 1, Fig. 1 is wireless cascade sound system of the present utility model, comprises at least one wireless cascade sound equipment 10 and audio frequency transmitting apparatus 20.Audio frequency transmitting apparatus 20 can be the mobile devices such as mobile phone, panel computer, it also can be TV with WiFi etc., described audio frequency transmitting apparatus 20 need possess wireless communication capability, can pass through the radio network techniques such as bluetooth, WiFi or 3G and send voice data to wireless cascade sound equipment 10, play this voice data by wireless cascade sound equipment 10.
As shown in Figure 2, Figure 2 shows that the structure chart of wireless cascade sound equipment 10.Audio playing module 12, NFC transmitter module 13, NFC induction module 15 and wireless network module 14 that wireless acoustics 10 comprises CPU11, is connected with CPU11.Wireless network module 14 can be WiFi module, bluetooth module or 3G module, and the wireless network module that other those skilled in the art can consider is equally applicable to the utility model.Wireless cascade sound equipment 10 of the present utility model also can be the equipment such as mobile phone with music playback function, panel computer.
Because the NFC communications protocol can be at swap data initiatively and under passive two kinds of patterns.Under Passive Mode, start NFC initiating equipment (main equipment), the NFC initiating equipment provides radiofrequency field (RF-field) in whole communication process.It can select wherein a kind of transmission speed of 106kbps, 212kbps or 424kbps, and data are sent to another equipment.Another equipment is called NFC target device (from equipment), needn't produce radiofrequency field, and working load modulation (load modulation) technology, speed that namely can be identical is with the data back initiating equipment.This communication mechanism is compatible with the contact type intelligent card based on ISO14443A, MIFARE and FeliCa, therefore, the NFC initiating equipment can detect contact type intelligent card or NFC target device with identical connection and initialization procedure, and set up contact with it under Passive Mode.
When a wireless cascade sound equipment 10(is called for short sound equipment A) when beginning the voice data of audio plays transmitting apparatus 20, this sound equipment A starts NFC transmitter module 13 simultaneously, and NFC transmitter module 13 provides radiofrequency field.In above-mentioned sound equipment A playing process, be called for short sound equipment B such as another wireless cascade sound equipment 10() also need music playing, only need sound equipment B is just touched at the sound equipment A of music playing, then the NFC induction module 15 of sound equipment B send back to sound equipment A with identity information, and sound equipment A carries out authentication to sound equipment B.After authentication was passed through, sound equipment A set up wireless network by wireless network module 14 with sound equipment B and is connected.This moment, sound equipment B received the voice data that sound equipment A transmits by wireless network module 14, and play this voice data by audio playing module 12.
Wireless cascade sound equipment 10 of the present utility model can also comprise the display module (scheming not shown) that is connected with CPU11, is used for showing corresponding information and man-machine interaction.
