如图1所示,本设计的第一实施形态的电话装置,具有采集使用者发声声音的通话麦克4, CD播放器和收音机等输出音频信号的音频发生单元7。 1, a first embodiment of the present design of the telephone device, the user having acquired audio calling Mike 4, CD players, radios and the utterance voice output audio signal generating unit 7. 通话麦克4采集的声音信号和从音频发生单元7输出的音频信号全都能输出混音单元2,在该混音单元2混合。 Call microphone sound signal collected 4 and the output from the audio generation unit 7 can output an audio signal mixing unit 2 full, 2 mixed in the mixing unit. 在混音单元2混合的所述声音信号和所述音频信号输入模数转换及编解码回路6,从模拟信号转换成数字信号后,被编码处理输入收发单元5。 After mixing the sound signal mixing unit 2 and the audio signal input of analog to digital conversion and encoding and decoding circuit 6, converted from an analog signal into a digital signal, the encoding process is input transceiver unit 5. 接收单元5,例如,Blue-Tooth模块借助天线8通过无线通信跟携带电话9连接,将从上述模数转换及编解码回路6输入的声音信号和音频信号借助电话线路从携带电话9发送给通话对方。 The receiving unit 5, e.g., Blue-Tooth module 8 by wireless communication via the antenna 9 is connected with the portable telephone, from said analog to digital conversion circuit and a sound signal codec and an audio signal input via telephone line 6 to the transmission call from a portable telephone 9 other side. 或者,接收单元5通过携带电话9 接收从通话对方发送而来的声音信号。 Alternatively, the receiving unit 5 receives the transmission from a sound signal from a portable telephone 9 via caller. 另外,也可以将接收单元5跟携带电话9 一体化,模数转换及编解码回路6的声音信号和音频信号能够直接输入携带电话9。 Further, the receiving unit 5 may be a portable telephone with integrated 9, analog to digital conversion and encoding and decoding circuit 6 and the audio signal a sound signal can be input directly to a portable telephone 9.

根据该电话装置,能够将使用者(发送侧的发话者)的声音和发送侧的音频信号重叠发送给通话对方(接收侧),因此通话对方能够听到使用者声音的背景音频(例如,CD的乐曲)。 The telephone apparatus, the user is able to (transmit caller side) and a sound transmitting side transmits audio signals to overlap the communication partner (reception side), the other party can hear the call so the background audio voice of a user (e.g., CD music). 但是,在音频发生单元2没有输出音频信号时,通话麦克4采集的声音信号(使用者的声音)能够单独发送给通话对方。 However, when the audio generating unit 2 does not output an audio signal, the call sound signal (user's voice) can be transmitted to the communication partner Mike 4 individually collected. 图1的符号3,是由没有图示出的数模转换器及编解码器构成的声音信号等 A sound signal symbol 3 in FIG. 1, is composed of a not illustrated digital to analog converter and codecs

级检测单元,将通话麦克4输出的AC声音信号转换成DC信号(比如,AC声音信号Vpp二O. 5V时转换成DOIV, AC声音信号Vpp二0.3V时转换成DC二0. 7V),之后,通过编码器对该DC信号的值进行编码处理输出给中央控制单元1。 Level detecting unit, the call AC audio signal outputted from microphone 4 is converted into a DC signal (for example, AC Vpp conversion sound signal into two O. 5V DOIV, Vpp two sound signals converted AC to DC 0.3V when two 0. 7V), Thereafter, the coding process is output to the central control unit 1 through the encoder value of the DC signal. 中央控制单元1基于存储在该中央控制单元1内的等级情报,相应于声音等级检测单元3检测出的声音信号等级,控制在所述混音单元2被混合的音频信号的混合量(从混合单元2输出的音频信号的输出等级)。 The central control unit 1 based on stored in the central control unit in an information level corresponding to the sound level detection unit 3 detects the sound signal level, controlling the amount of mixing two audio signals are mixed in the mixing unit (from the mixing output level of the audio signal output unit 2).

在此,在混音单元2中的音频信号的混合量的控制方法可以进行多种考虑。 Here, a method of controlling the amount of mixing in the audio signal mixing unit 2 may be a variety of considerations. 首先,考虑使用者发声的声音等级高的时候,中央控制单元1让音频信号的混合量低一些,使用者发声的声音信号等级低或者没有发声的时候,让音频信号的混合量增加的控制方法。 First, consider the user of the voice of the high sound level, the central control unit 1 so that the low amount of mixing some of the audio signal, a low level of user audible sound or no sound signal when the audio signal so that an increased amount of control of the mixing method . 根据该控制方法,使用者发声的声音不会因音频信号而被削弱,这样一来,通话对方侧就能够清楚地听到使用者(发送侧的说话人)的声音。 According to this control method, the utterance voice of a user of the audio signal will not be impaired, this way, the caller-side user can clearly hear (transmission side speaker) sound. 另一方面,和所述控制方法相反,使用者发话声音等级高的时候, 中央控制单元1增加音频信号的混合量,使用者发声的声音等级低或者不发声的时候,让音频信号的混合量低一些的控制方法也能考虑。 On the other hand, and contrary to the control method, when a user speech of high sound level, increased central mixing unit 1 controls the audio signal, audible sound level is low or the user does not sound when the audio signal so that the amount of mixing lower control method can also be considered. 根据这个控制方法, 能够把使用者发声的声音信号等级和音频信号等级的比率维持在一定水平。 According to this control method, the ratio of the user utterance to the sound signal level and the audio signal level is maintained at a certain level. 让中央控制单元1进行上述的哪种控制,该电话装置的制造商能够有选择地设定, 或者使用者为了能够切换上述控制方法,也可以把没有图示的切换开关设置在电话装置上。 For the central control unit 1 which controls the above-described, the manufacturer of the telephone apparatus can be selectively set, or the user can switch to the above-described control method can also switch (not shown) provided on the telephone device.

下面,参照图2说明本设计第2实施形态的电话装置。 Next, the telephone device described in this design of the second embodiment 2 with reference to FIG.

该第2实施形态的电话装置和所述第1实施形态的电话装置一样,具有,采集使用者发声后的声(声音)的通话麦克4,输出CD播放器和收音机等的音频信号的音频发生单元7。 The second embodiment of the telephone apparatus and the first embodiment of the telephone apparatus as having audio sound collection after the user utterance (voice) conversation microphone 4, the output of a CD player and radio audio signal occurs 7 units. 通话麦克4采集的声音信号经由中央控制单元1输出给接收单元5,借助电话线路从携带电话9发送给通话对方。 4 call the microphone sound signal acquired to the receiving unit 5 via the output of the central control unit 1, transmission from the telephone line to the portable telephone 9 via the communication partner. 另一方面,接收单元5通过携带电话9接收从通话对方发送而来的声音信号。 On the other hand, the receiving unit 5 receives a sound signal transmitted from the portable telephone from a caller through 9. 另外,也可以设计成将接收单元5跟携带电话9 一体化,携带电话9直接跟中央控制单元1连接。 Further, the receiving unit may be designed to 5 integrated with the portable telephone 9, 9 with the portable telephone unit 1 is connected directly to the central control.

通话对方的声音信号从接收单元5输入模数转换及编解码回路6,该模数转换及编解码回路6将通话对方的声音信号从数字信号转换成模拟信号输入混音单元2。 Caller audio signal receiving unit 5 from the input analog-digital conversion circuit 6 and a codec, the codec and analog to digital conversion circuit 6 converts a voice signal from the calling party is a digital signal to an analog input signal mixing unit 2. 另一方面,从音频发生单元7输出的音频信号也输入混音单元2。 On the other hand, the audio signal generating unit 7 audio output from the mixing unit 2 is also input. 混音 Mixing

7单元2能够将通话对方的声音信号和音频发生单元7的音频信号混合,放大器11以电子音量控制10调整过的值增幅,从扬声器12声音输出。 7 unit 2 can mix audio signal caller's voice signal and the audio generating unit 7, the amplifier 11 to increase the value of the electronic volume control 10 is adjusted, the sound outputted from the speaker 12.

根据该第2实施形态的电话装置,能够把通话对方(发送侧的发话者)的声音重叠在使用者侧(接收侧)的音频信号上,从扬声器12输出,因此使用者能够听到通话对方声音的背景音频,比如CD的乐曲。 On the second telephone apparatus according to the embodiment, it is possible to call the other party (caller side of the transmission) in the user's voice superimposed side (reception side) of the audio signal output from the speaker 12, the user is able to hear the caller background audio sound, such as music CD's. 不过,音频信号没有从音频发生单元2输出时,通话对方的声音也能从扬声器12独立输出。 However, the audio signal does not occur from the audio output unit 2, the caller's voice output from the speaker 12 is also independent from.

在图2所示的声音信号等级检测单元3,检出从数模转换及编解码回路6输出的通话对方的声音信号等级发送给中央控制单元1。 In the sound signal level detection unit shown in FIG. 3, the detection is sent to the central control unit a signal level from the sound codec digital-analog conversion circuit 6 and the output of the caller. 中央控制单元1基于存储在该中央控制单元1内的等级情报,相应于声音信号等级检测单元3检测出的声音信号等级控制所述混音单元2混合的音频信号的混合量(从混音单元2输出得音频信号的输出等级)。 Mixing an amount of the sound level of the central control unit 1 based on information stored in the central control unit 1, the sound signal corresponding to the level detection unit 3 detects a signal mixing unit 2 for controlling the level of the mixed audio signal (from the mixing unit 2 to obtain an output audio signal output level).

在此,在混音单元2里的音频信号的混合量的控制方法和所述第1实施形态的电话装置一样可以考虑多种方式。 Here, as in the method of controlling the amount of mixing in the mixing unit 2 and the audio signal of the first embodiment of the telephone apparatus can be considered a variety of ways. 首先,能够考虑通话对方发声的声音等级高时,中央控制单元1让音频信号的混合量低一些;通话对方发声的声音信号等级低或者不发声时,让音频信号的混合量增加的控制方法。 First of all, can be considered high caller utterance sound level, the central control is low so that an audio signal mixing amount of the unit 1 Some; low caller utterance sound signal level or unvoiced, so that an audio signal mixing increased control method. 根据这个控制方法,通话对方的声音不会被因为音频信号而被消除,使用者能够清楚地听到通话对方(发送侧的说话人)的声音。 According to this control method, caller's voice will not be because the audio signal is removed, the user can clearly hear the caller (the speaker on the transmission side) of the sound. 另一方面,和上述控制方法相反,可以考虑通话对方的声音等级高时,中央控制单元1让音频信号的混合量增加;通话对方的声音等级低或者不发声的时候,让音频信号的混合量低一些的控制方法。 The mixing amount of the low sound level or the caller does not sound when the audio signal so that; the other hand, contrast and the control methods can be considered when a high level of caller's voice, so that the central mixing amount of the audio signal of the control unit 1 increase lower control methods. 根据这个控制方法,能够将通话对方的发话的声音等级和音频信号等级的比率维持在一定的水平上。 According to this control method, the ratio of the caller's speech and sound level of the audio signal level can be kept at a certain level. 在中央控制单元1让其进行哪种的控制,该电话装置的制造商可以选择地决定,或者为了使用者能够切换上述控制方法,将没有图示的切换开关设置在该电话装置上。 The central control unit 1 which is allowed to control, the manufacturer of the telephone device can be selectively determined, or the user can switch to the above-described control method, the switch (not shown) provided on the telephone device.

下面,参照图3,说明本设计的电话装置的声音信号和音频信号的混合动作。 Referring to FIG 3, the operation of the sound mixing apparatus according to the present design of the telephone signal and the audio signal.

首先,声音信号等级检测单元3将使用者(第1实施形态的时候)或者通话对方(第2实施形态)的声音信号模数变换(步骤301)。 First, the sound signal a sound level detection unit 3 the user (when the first embodiment) or the communication partner (second embodiment) of the analog-digital conversion signal (step 301). 随后,对声音信号进行编解码处理将该编解码处理后的值输入中央控制单元1。 Then, the sound signal codec processing input value after the codec processing central control unit 1. 中央控制单元1把输入的值和基准值(比如0.5V)相比较(步骤302)。 A central control unit of the input value and the reference value (for example 0.5V) is compared (step 302). 该比较的结果,输入值在基准值以下时,中央控制单元1判断混音单元2混合的音频信号的混合量(从混音单元2输出的音频信号的音量)是否是Hi状态(高的状态)(步骤303)。 Result of the comparison, when the value of the input reference value, the central mixing of the audio signal mixing unit 2, the control unit 1 determines mixer (volume of the audio signal output from the mixing unit) is the Hi state (high state ) (step 303). 己经是Hi状态时,返回步骤302的比较动作。 Already a Hi state, the comparison operation returns to step 302. 在步骤303判断音频信号的混合量是Lo状态(低的状态),该Lo状态持续多长时间,确认从上次Hi状态切换到了Lo状态的时刻到当前的经过时间,判断该经过时间不满所定时间(比如Is) 吗(步骤304)。 In step 303 determines that the mixed amount of the audio signal is Lo state (low state), the Lo state how long, to confirm the switch from the last Hi state to the time when the Lo state to the current elapsed time, determining that the elapsed time is less than a predetermined time (for example, Is) it (step 304). 所述经过时间不满所定时间时,返回步骤302。 The elapsed time is less than a predetermined time, returns to step 302. 判断所述经过时间是所定时间以上时,中央控制单元1将在混合回路2混合的音频信号的混合量设定为Hi状态的控制命令输入混合回路2 (步骤305)。 Determining the elapsed time is more than a predetermined time, the central control unit 1 the second mixing circuit mixing amount of the input audio signal mixing circuit 2 is set (step 305) as a control command in the Hi state in the mixing. 根据该动作,使用者或者通话对方,例如在通话中发话停止数秒时,混合回路2中的音频信号的混合量自动增加。 According to this operation, the user or the caller, for example, when the utterance is stopped for a few seconds, the mixing circuit automatically increases the amount of mixing in the audio signal 2 in a call.

另一方面,步骤302的比较结果超过基准值时,中央控制单元l判断混合回路2混合的音频信号的混合量是否是Hi状态(步骤306)。 On the other hand, the comparison result of step 302 exceeds the reference value, the central control unit determines the mixing amount l in the mixing circuit 2 whether the mixed audio signal is Hi state (step 306). 所述混合量是Lo 状态时,返回步骤302。 The mixing amount is in the Lo state, the process returns to step 302. 所述混合量是Hi状态时,判断该Hi状态持续了多长时间呢,即确认从上次的Lo状态切换到Hi状态的时刻到当前时刻的经过时间, 判断该经过时间未满所定时间(比如500ms)吗(步骤307)。 The mixing amount is a Hi state, the Hi state is determined how long it lasted, i.e., the confirmation timing is switched from the Hi state to the Lo previous state to the current time point elapsed time, determining that the elapsed time is less than a predetermined time ( For example 500ms) it (step 307). 所述经过时间未满所定时间时,返回步骤302。 The elapsed time is less than a predetermined time, returns to step 302. 判断所述经过时间在所定时间以上时,中央控制单元1将设定混合回路2混合的音频信号的混合量为Lo状态的控制命令输入混合单元2 (步骤308)。 Determining the elapsed time when a predetermined time or more, the central control unit 1 set 2 mixed in the mixing circuit of the audio signal is the mixed state of an input control command Lo mixing unit 2 (step 308). 根据这个动作,使用者或者通话对方,比如在通话中的短时间停止发声,随后接着发声的时候,在混合回路2的音频信号的混合量自动降低。 According to this operation, the user or the caller, for example, in a short time stop sounding the call, and then followed by the voice of the mixing amount of the audio signal circuit 2 is automatically reduced in the hybrid.

在步骤304和步骤307中,音频信号的混合量没有持续所定时间以上时,不切换混合量的设定,故此防止能够音频信号的音量在短时间内激烈增减。 In step 304 and step 307, the mixed audio signal is not the amount of time or more predetermined duration, setting the amount of mixing is not switched, therefore preventing the volume of the audio signal can be increased or decreased in a short time heated.

另外,中央控制单元l将步骤302的比较动作执行了500ms的时间间隔。 Further, the central control unit 302 l action of the comparing step is performed 500ms interval. 因此,在混合单元2的音频信号的混合量的设定被切换后,不管声音信号等级检测单元3检测的声音信号等级,所述混合量能够在所定时间内进行一定的保持。 Thus, after setting the mixing amount of the audio signal mixing unit 2 is switched, regardless of the level of the sound signal sound signal level detected by the detecting unit 3, the mixing amount can be kept constant within a predetermined time.

以上,说明了关于本设计的最佳实施形态,但本设计的保护范围。 Above described preferred embodiment of the present design is on, but the scope of the present design. 不限于该实施形态说明的范围,在记载在实用新型登陆请求的范围的技术范围内,根据本设计的技术方案以及本设计的构想,进行替换或者变更的都被包含在其内。 This embodiment is not limited to the scope described in the technical scope of the invention described in the scope of the login request, according to the design concept and the technical solution of the present design, the replacement or change are to be embraced therein.

比如,在图3的流程图中,已经说明过中央控制单元l用Hi状态和Lo状态的两个步骤切换混合单元2混合的音频信号的混合量,但也能够相应于声音信号等级检测单元3检测出的声音信号等级,以更加细腻的步骤让所述混合量变化。 For example, in the flowchart of FIG. 3, it has been described mixing amount of the central control unit switching l audio signal mixing unit 2 with two mixing steps Hi and Lo states of the state, but can also be a sound signal corresponding to the level detection unit 3 sound signal level detected, so that a more delicate step of mixing said amount of change.
