[0042] 实施例5 [0042] Example 5

[0043] 与实施例4不一样的地方在于,以便携播放器200作为播放设备,耳机作为音响设备,在所述便携播放器上设置三轴加速度传感器SN1,以及在耳机的两个耳机部分别设置有三轴加速度传感器SN2和SN3,如图2所示。 [0043] Example 4 is that not the same place, to the portable player as a playback device 200, audio equipment as a headphone, a triaxial acceleration sensor SN1 is provided on the portable player, and the other two portions of the headset the headset It is provided with a triaxial acceleration sensor SN2 and SN3, as shown in FIG.

[0044] 由于两个耳机是相对的,则左右两个耳机中的三轴加速度传感器SN2和SN3的XYZ轴必有一轴是相对的。 [0044] Since two headphones are opposed, the two left and right headphone triaxial acceleration sensor SN2 and SN3 of the XYZ axes must be opposite to a shaft. 例如,当便携播放器中的三轴加速度传感器的XYZ轴与左耳机中的三轴加速度传感器XYZ轴是一致时,则与右耳机的三轴加速度传感器XYZ轴是相对的。 For example, when the triaxial acceleration sensor XYZ axes of XYZ axis acceleration sensor of the portable player and the left headphone is consistent, the right earphone triaxial acceleration sensor is relative XYZ axes.

[0045] 便携式播放器200通过接收来自左右耳机中的三轴加速度传感器SN2和SN3输出的加速度数据与其内部设置的三轴加速度传感器SNl输出的加速度数据作比较,可以确定所述两个耳机部的物理位置信息。 [0045] The portable player 200 by receiving the right and left acceleration data output from the triaxial acceleration sensor SNl triaxial acceleration sensor SN2 in the headset and acceleration data outputted from its internal SN3 provided for comparison, can determine whether the two earphone portions physical location information.

[0046] 如果所检测到的耳机的物理位置信息与通过设置加速度传感器所规定的左右耳机的逻辑位置信息不一致时,就切换便携播放器的左右声道的输出。 [0046] If the logical position information of the detected physical position information of the left and right headphone earphone defined by the acceleration sensor not, the switching of the output left and right channels of the portable player.

[0047] 可以将实施例5简述如下:通过比较播放设备中的传感器的数据和其接收来自两个耳机的传感器的数据来确定耳机的左右是否佩戴正确。 [0047] Example 5 can be summarized as follows: to determine whether the left and right headphones worn correctly by comparing the data playback apparatus in which a sensor and sensor data received from the two earphone. 为了使本实施例更清楚,将两个耳机分别编号为I号和2号。 In order to make more apparent the present embodiment, the number and numbered I, two headset 2. 在设计过程中,预先将其传感器数据与播放器的传感器数据一致的耳机设置为左耳机,相反的为右耳机。 In the design process, which is consistent advance sensor data sensor data with the player to the left earphone headset provided opposite to the right headphone. 例如,如果I号耳机插入左耳朵;2号耳机插入右耳朵,此时的佩戴是正确的,这时播放设备接收到左耳朵中的I号耳机的传感器数据与播放设备的传感器数据是一致的,而右耳朵中的2号耳机的传感器数据与播放设备的传感器数据是相反的,则不需要切换。 For example, if I, into the left ear headphone; sensor data and the sensor data playback apparatus No. 2 into the right ear headphones, in this case wearing is correct, then the playback apparatus receives the left ear headphone I, is consistent with and the sensor data and the sensor data playback apparatus in the right ear headphone 2 is reversed, there is no need to switch.

[0048] 假如将两个耳机调换后,即佩戴不正确,I号的耳机插入右耳朵,2号耳机插入左耳朵,而此时播放设备接收到2号耳机的传感器数据与播放设备的传感器数据是一致的,而I号耳机的传感器数据与播放设备的传感器数据是相反的,由于判断到2号与播放器是一致的,所以2号为左耳机,I号为右耳机。 [0048] If the two rear replacement headset, i.e., wear incorrect, the I number into the right ear headphones, earphone 2 is inserted into the left ear, but this time the playback apparatus 2 receives the sensor data and the earphone sensor data playback apparatus it is the same, but the sensor data and the sensor data playback apparatus I, the headset is reversed, since the player is determined to 2 and the number is consistent, the headphone 2 to the left, the right headphone No. I. 需要切换信号。 Need to switch signal.

[0049] 虽然在本申请的说明书中,以笔记本电脑、台式机、便携式播放器作为实例描述了本发明,但是,播放设备并不限于此,而是可以包括诸如DVD播放器、MP3/MP4、V⑶播放器等各种能够进行多个声道输出的设备。 [0049] Although in the present application specification, notebook computer, desktop computer, portable player according to the present invention is described as an example, however, the playback apparatus is not limited thereto, but may include information such as DVD players, MP3 / MP4, V⑶ various players, devices capable of a plurality of output channels.

[0050] 本发明的技术方案通过获取发声装置的物理位置信息,并将其与输出至该发声装置的声道信号所包含的逻辑位置信息进行比较,可以确定发声装置的物理位置信息与输出至该发声装置的声道的逻辑位置信息是否一致,在比较结果为不一致时,将声道信号切换为另一声道信号,其中另一声道信号包含的逻辑位置信息与发声装置的物理位置信息一致,从而实现了发声装置的声道自适应,并提高了用户操作的方便性。 [0050] aspect of the present invention, and by comparing the acquired physical position information of the sound producing device with its logical position information of the channel signal output to the sound device included, physical location information may be determined and the sound output means to whether the logical position information of the channel sounding device coincides, when the comparison result is inconsistent, the channel signal is switched to the other channel signal, wherein the physical location of the logical address information contained in the signal of other channel sounding device information consistency, enabling channel adaptive sound producing device, and improving the convenience of user operation.
