具体实施方式
图1是表示本发明的一实施方式的免提通话装置。
如图1所示，免提通话装置1通过车载总线(Bus)4连接到导航装置2及车载音响3。此外，免提通话装置1连接到移动电话5。
免提通话装置1包括：MPU(Micro Processing Unit；微处理器单元)10、话筒11、DSP(Digital Signal Processor；数字信号处理器)12、开关13、功率放大器14a、14b、中心扬声器15a、15b、以及总线I/F电路16。
MPU10执行在未图示的ROM(Read Only Memory；只读存储器)等中所存储的程序。所执行的程序是后述的免提通话装置1的动作的执行等用于控制各个部分的程序。在本实施方式中，MPU10构成本发明的扬声器选择部件及扬声器切换部件。
话筒11是用户用于输入免提通话的送话声音的装置。
DSP12被编程以对声音信号进行电平(level)调整、延迟时间调整、合成处理等的声音处理。被进行该声音处理的声音信号是用于免提通话的来自移动电话5或话筒11等的声音信号。在本实施方式中，DSP12构成本发明的测试声音信号生成部件和声压电平检测部件。此外，DSP12构成对受话声音信号、引导声音信号、以及音响声音信号进行滤波而使特定的频带(300Hz-4kHz)的信号通过的带通滤波器。DSP12也可以根据要滤波的信号是受话声音信号、或引导声音信号、或音响声音信号而变更所通过的信号的频带。
开关13根据MPU10的选择而切换用于输出来自DSP12的受话声音的目的地。
功率放大器14a、14b将来自开关13的受话声音信号放大。
中心扬声器15a不面向话筒11地被设置在车辆中。中心扬声器15b面向话筒11地被设置在车辆中。中心扬声器15a、15b最好具有较窄的方向性。中心扬声器15a、15b将功率放大器14a、14b放大后的表示受话声音信号的受话声音分别输出。
总线I/F电路16连接到车载总线4。由此，MPU10连接到导航装置2及车载音响3。
导航装置2将表示用于引导路线的引导声音的引导声音信号输出。
车载音响3将表示音响声音的音响声音信号输出。在车载音响3中，连接有对音响声音信号进行滤波而使高频段(4kHz以上)的信号通过的HPF(High Pass Filter；高通滤波器)17a、17b，以及对音响声音信号进行滤波而使低频段(300Hz以下)的信号通过的LPF(Low Pass Filter；低通滤波器)18a、18b。
通过了HPF17a、17b和LPF18a、18b的音响声音信号，通过放大该音响声音信号的功率放大器19a、19b、20a、20b，从车载扬声器21a、21b、22a、22b被分别输出。
即，来自移动电话5的受话声音信号、来自导航装置2的引导声音信号、以及来自车载音响3的音响声音信号，由DSP12进行声音处理，通过开关13和功率放大器14a、14b，从中心扬声器15a、15b被分别输出。
图2和图3表示免提通话装置1的动作。首先，MPU10判断是否有对移动电话5的呼入(S1)。这里，在判断为没有对移动电话5的呼入(incomingcall)时，免提通话装置1的动作转移到后述的步骤S11。
接着，在判断为有对移动电话5的呼入时，MPU10判断是否正从中心扬声器15a、15b输出音响声音(S3)。再有，在有对移动电话5的呼入时，通过车载音响3而停止对车载扬声器21a、21b、22a、22b的音响声音信号的输出(S2)。
在判断为正从中心扬声器15a、15b输出音响声音时，MPU10使开关13停止对中心扬声器15a、15b的音响声音信号的输出(S4)。
接着，MPU10从中心扬声器15a、15b产生被存储在未图示的RAM(Random Access Memory；随机存取存储器)等中的呼入音。若根据车载总线4上所连接的未图示的输入装置的操作而开始免提通话，则MPU10控制移动电话5，以使DSP12输出受话声音信号。然后，MPU10为了排除回波对送话声音的影响，选择中心扬声器15a作为输出受话声音的扬声器(S5)。开关13根据MPU10中的选择而将DSP12的连接目的地切换到功率放大器14a。
接着，MPU10判断是否结束了免提通话(S6)。在判断为结束了免提通话时，MPU10使开关13再开始对中心扬声器15a、15b的音响声音信号的输出(S7)。
在步骤S3中，在判断为从中心扬声器15a、15b没有在输出音响声音时，MPU10为了排除在送话声音中受到的回波的影响，选择中心扬声器15a作为输出受话声音的扬声器(S8)。开关13根据MPU10的选择，将DSP12的连接目的地切换到功率放大器14a。
接着，MPU10判断是否结束了免提通话(S9)。在判断为结束了免提通话时，免提通话装置1的动作转移到后述的步骤S10。
接着，车载音响3再开始对车载扬声器21a、21b、22a、22b的音响声音信号的输出(S10)，免提通话装置1的动作返回到步骤S1。
接着，MPU10判断是否有通过总线I/F电路16而请求来自导航装置2的声音引导(S11)。这里，在判断为没有请求来自导航装置2的声音引导时，免提通话装置1的动作返回到步骤S1。
接着，在判断为有请求来自导航装置2的声音引导时，MPU10判断是否正从中心扬声器15a、15b输出音响声音(S12)。
在判断为正从中心扬声器15a、15b输出音响声音时，MPU10使开关停止对中心扬声器15b的音响声音信号的输出(S13)。
接着，MPU10为了提高引导声音的清晰度，选择扬声器15b作为输出引导声音的扬声器(S14)。开关13根据MPU10的选择，将DSP12的连接目的地切换到功率放大器14b。
接着，MPU10使开关13再开始对中心扬声器15b的音响声音信号的输出(S15)，免提通话装置1的动作返回到步骤S1。
在步骤S12中，在判断为从中心扬声器15a、15b没有在输出音响声音时，MPU10为了提高引导声音的清晰度，使开关13选择扬声器15b作为输出引导声音的扬声器(S16)，免提通话装置1的动作返回到步骤S1。
这里，参照图4说明话筒的频率特性和免提通话时传送到话筒的受话声音的声压电平之间的关系。
在以往的免提通话装置中，如图4的(a)所示，话筒25被设置在输出受话声音的扬声器23a、23b的再现区域24内。这种情况下，在话筒25的输入灵敏度较高的频带中，传送到话筒25的受话声音的声压电平升高，所以在输入到话筒25的送话声音中受到的回波的影响变大。
另一方面，在本实施方式的免提通话装置1中，如图4的(b)所示，扬声器15a输出声音的方向和从扬声器15a面向话筒11的方向形成60度的角度，话筒11被设置在输出受话声音的扬声器15a的再现区域26外部。这里，免提通话时，不从车载扬声器21a、21b、22a、22b输出声音(参照S2)。
这种情况下，在话筒11的输入灵敏度较高的频带中，传送到话筒11的受话声音的声压电平比以往的声压电平低，所以在输入到话筒11的送话声音中受到的回波的影响与以往的影响相比降低了相当于箭头27所示的声压电平部分。
于是，输出受话声音的扬声器15a以使其输出声音的方向和从扬声器15a面向话筒11的方向形成60度以上的角度来设置较好。
这样的本发明的实施方式的免提通话装置1，从车辆中不面向用于免提通话的话筒11设置的中心扬声器15a输出受话声音而不进行用于回波消除的声音信号处理，所以能够降低在送话声音中受到的回波的影响而不使送话声音劣化。
再有，在本实施方式中，说明了免提通话装置1具有中心扬声器15a、15b的两台中心扬声器，但也可以具有3台以上的中心扬声器。
此外，在本实施方式中，说明了将中心扬声器15a作为输出受话声音的扬声器，但也可以通过将以下说明的扬声器选择处理所选择的扬声器作为输出受话声音的扬声器。
图5是表示本发明的一实施方式的扬声器选择处理的流程图。
首先，DSP12基于在ROM中预先存储的测试声音数据而生成对话筒11的输入灵敏度较高的三个频率的测试声音信号(S21)。
接着，MPU10对输出表示了由DSP12所生成的三个频率的测试声音信号的测试声音的扬声器进行切换(S22)。
接着，DSP12检测由MPU10切换后的扬声器输出、被输入到话筒11中的测试声音的声压电平(S23)。
接着，MPU10判断通过DSP12是否对所有的扬声器检测出测试声音的声压电平(S24)。这里，在判断为通过DSP12未对所有的扬声器检测出测试声音的声压电平时，免提通话装置1的动作返回到步骤S22。
另一方面，在判断为通过DSP12对所有的扬声器检测出测试声音的声压电平时，MPU10选择测试声音的声压电平的总和最低的扬声器(S25)。
再有，在步骤S21中，说明了测试声音信号作为对话筒11的输入灵敏度较高的三个频率的信号，但只要是对话筒11的输入灵敏度较高的一个频率以上的信号就可以。
此外，在步骤S25中，说明了MPU10选择声压电平的总和最低的扬声器，但也可以选择声压电平的总和为规定值以下的至少一个扬声器。
此外，与扬声器选择处理同样，DSP12也可以生成测试声音信号，检测被输入到话筒11的测试声音的声压电平，进而根据检测出的声压电平来设定带通滤波器的系数。
此外，在本实施方式中，说明了在车载总线4中，连接了导航装置2和车载音响3的例子，但除了它们以外，也可以连接ETC(Electronic TollCollection；电子收费采集)车载装置、以及VICS(Vehicle Information andCommunication System；车辆信息和通信系统)车载装置等其他车载装置。
此外，MPU10、DSP12、开关13、以及总线I/F电路16也可以由集成电路构成。
再现区域26被分成与轴26a对称或大致对称的两个区域26b、26c。从扬声器15a面向话筒11的方向28和受话声音沿轴26a行进的方向26d之间形成的角度在60度以上。而且，话筒11被设置在未图示的方向盘(handle)附近。
工业实用性
如上所述，本发明的免提通话装置具有能够降低送话声音中受到的回波的影响而不使送话声音劣化的效果，例如，作为车辆上装载的免提通话装置是有用的。
