处理过的多路语音模拟信号再经过 DSP206进行信号的数字 分析处理, DSP将各方向釆集的信号经过分析处理后发出所需要的说话人的语 音电信号; 该语音电信号经过一个功率放大器即第一功率放大器 208放大, 从 而去驱动后面的电磁线圏即电磁发送线圏 210; 电磁发送线圏 210将功率放大 后的语音电信号转换为语音电磁信号, 并向外发送。 通过信号处理模块 204和 DSP206对语音模拟信号的处理, 有效实现了语音信号的处理转变。 电磁线圏可选用任意具有导电功能的导线, 优选的, 该电磁线圏由漆包线 缠绕而成。 漆包线直径小、 占用空间小, 能够减轻移动终端的体积和系统负担。 电磁线圏在缠绕时, 线圏匝数越多则发送的电磁信号越强。 优选的, 线圏匝数 为 20至 30匝。 该匝数在通常情况下即可满足听力障碍人群的助听需要, 且能 够保证不过多占用移动终端的体积。 功率放大器的功放倍数与线圏的匝数 (由 线圏匝数导致的电磁信号强度)可以由本领域技术人员根据实际情况适当匹配 设置, 以使二者有效匹配。 这样, 手机就能拾取周围说话人的声音并通过电磁线圏感应出相应强弱的 带有语音频率的电磁信号。 同时, 该信号强度能够被一定范围内的接收装置收 到, 超出该范围则由于强度的因素不能被其他接受器所收到。 因此做到了实用 性、 有效性。 为了有效实现移动终端的助听功能, 还需要一个能接收移动终端发送的电 磁信号的耳机。 以下结合图 3 , 对能够接收语音电磁信号, 与移动终端配合使 用的耳机作以介绍。 参照图 3 , 示出了才艮据本发明实施例的一种耳机的结构示意图。 本实施例的耳机包括: 电磁感应线圏 (即电磁接收线圏 302 )、 功率放大器 (即第二功率放大器 304 )、 以及微型受话器 306 (即微型喇叭;)。 上述耳机可以以任何适当形式实现,优选的,为了保证听筒的入耳体积小、 隐蔽性、 功耗小, 特配合移动终端设计了一个入耳式微型耳塞。 它的实现原理 是, 当手机(移动终端)发出带有声音信号的电磁波即语音电磁信号后, 入耳 式 ^啟型耳塞内所具有的电磁感应线圏 (即电磁接收线圏 302 ) 能够感应到其周 围的电磁场变化, 并能拾取该电磁波信号; 由电磁感应线圏 (即电磁接收线圏 302 ) 拾取到的信号强度可能很小, 因此不足以转换成声音信号 (即语音模拟 信号) 后被人的耳朵所接收到, 因此, 电磁感应线圏 (即电磁接收线圏 302 ) 感应到电磁波信号后将其转换为语音电信号, 并发送到后极的驱动放大电路即 第二功率放大器 304中,第二功率放大器 304将语音电信号做一定的功率放大, 再发送到后极的微型喇叭即微型受话器 306中, 微型受话器 306将该放大了的 语音电信号转换为语音模拟信号, 从而实现了将周围的声音信号还原成被人耳 能接收到的语音信号被人体接收。 同时, 整个入耳式 ^啟型耳塞的供电环节由一个小型纽扣电池供电。 由于入 耳式微型耳塞内部处理电路简单, 且功耗小, 因此利用小型的纽扣电池就能实 现供电。 这种设计保证了入耳式耳塞绝对的小型化, 能够很好的做到隐蔽性、 小型性、 佩戴舒适等对助听器的要求。 在实现上, 可以将图 2所示的手机和图 3所示的啟型耳塞配套使用, 并且 保证微型耳塞的信号接收距离应在一定的范围内且不能过大以免误拾取其他 信号, 因此, 本领域技术人员可以根据实际情况利用现有电磁技术, 将手机端 电磁发送线圏电路及微型耳塞端电磁接收线圏电路部分进行良好的匹配。 另一 方面, 本领域技术人员可以根据实际情况利用现有电磁技术, 对手机发送端线 圏匝数、 微型耳塞接收端线圏匝数与其相应的配合电路进行有效地匹配。 需要说明的是, 与本发明移动终端配合使用的接收耳机不限于上述实施例 中的耳机, 任意合适的可接收语音电磁信号的耳机均可与该发送语音电磁信号 的移动终端配合使用, 本发明对此不作限制。 当然, 上述实施例中的移动终端 (如手机)可做正常使用, 可设置只当工 作在助听器工作模式下时,打开助听器功能, 同时不影响手机的其他正常功能。 该具有助听器功能的移动终端发出与拾取到的周围语音信号相对应的电磁波 信号, 该电磁波信号被附近一个耳机如入耳式微型耳塞所接收到, 该耳塞利用 电磁波基本原理能够还原出移动终端部分拾取到的声音信号并通过一个微型 喇 p八发送到人耳中。 如果使用蓝牙无线功能替代电磁线圏, 则因蓝牙方式在实现上由于其电路 板大、 电池大、 供电所需电流大, 造成体积大, 功耗大, 因而在实现助听功能 时, 无法故到移动终端助听器的小型化、 实用性、 商用性, 无法实现电磁线圏 实现助听功能的便携性、 隐蔽性。 而使用本发明通过电磁线圏实现具有助听器 功能的手机及其无线微型耳塞, 则在技术实现上完全能够达到所需的功能效 果, 并能够有效保证耳塞的小型化, 在音效接收上能够达到助听器所具有的效 果, 同时保留了手机原有的功能。 因此, 根据本发明能够完全达到移动终端如 手机的实现, 并且操作简单有效, 特别适合老年人应用人群及听力障碍人群, 具有非常高的市场价值及商用价值。 参照图 4, 示出了才艮据本发明实施例的一种语音处理方法的步骤流程图。 本实施例的语音处理方法包括以下步骤: 步骤 S402: 移动终端将语音模拟信号转换为语音电信号, 对语音电信号进 行功率放大;

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Referring to FIG. 1, a block diagram of a structure of a mobile terminal according to an embodiment of the present invention is shown. The mobile terminal of this embodiment includes: a first power amplifier 102 configured to acquire a voice electrical signal and perform power amplification, and then send the signal to the electromagnetic transmission line 104; the electromagnetic transmission line 104 is set to a voice electrical signal that is amplified by power. Converted to a voice electromagnetic signal and send a voice electromagnetic signal. The voice electrical signal is obtained by the mobile terminal, and then converted into a voice electrical signal by analog-to-digital conversion, and then sent to the first power amplifier 102. The first power amplifier 102 acquires the voice electrical signal and performs power amplification to drive the electromagnetic The transmission line 104 transmits the power amplified audio signal to the electromagnetic transmission line 104. After receiving the voice electrical signal, the electromagnetic transmission line 104 converts the voice electrical signal into a voice electromagnetic signal and transmits it. When there is a device for receiving voice electromagnetic signals, such as a headset After receiving the voice electromagnetic signal, it can be amplified and converted into a voice analog signal, thereby realizing the hearing aid function of the mobile terminal. In the related art, the mobile terminal does not set any function that can support the hearing aid. For those who have hearing impairment, the mobile terminal can only use the volume of the mobile terminal to perform voice interaction, thereby greatly affecting the hearing dysfunction population. Use the experience of the mobile terminal. In this embodiment, the electromagnetic transmission line is disposed in the mobile terminal to transmit the voice electromagnetic signal, so that the receiving end having the received voice electromagnetic signal, such as the earphone, can receive the signal, thereby performing voice amplification to implement the hearing aid, thereby effectively The problem that the mobile terminal does not support the hearing aid function in the prior art is solved, and the mobile terminal can support the hearing aid function, and the effect of the hearing dysfunction population on the use experience of the mobile terminal is improved. Referring to FIG. 2, a schematic structural diagram of a mobile terminal according to an embodiment of the present invention is shown. The mobile terminal in this embodiment takes a mobile phone as an example. In addition to the functional modules common to the elderly machine and the mobile phone, the mobile phone also incorporates a hearing aid processing module. Other functional modules of the mobile phone besides the hearing aid processing module can use the prior art, and the principle thereof will not be described here because of its versatility. The entire hearing-assist mobile phone also has a hearing aid processing module that is still powered by the entire phone's lithium-ion battery, so there is no need for a separate power module. The user can be provided with an option to enter the hearing aid working mode by setting a menu in the mobile phone, and the user can select to enter the hearing aid working mode to activate the hearing aid processing module; or can be set after the user toggles or presses a certain button such as the number key, The mobile phone is in the hearing aid working mode, and the hearing aid processing module is activated. Of course, those skilled in the art can also set other suitable manners according to the need to start the mobile terminal to enter the hearing aid working mode, and start the hearing aid processing module. Through this setting, the user is greatly facilitated to start the operation of the hearing aid function of the mobile terminal, thereby improving the user experience. The hearing aid processing module of this embodiment may include: a microphone array 202 (ie, a microphone array;), a processing module including a signal processing module 204 and a DSP (Digital Signal Processor) 206, a first power amplifier 208, and an electromagnetic Send line 210. The handset hearing aid processing module is provided with a plurality of microphones (ie, microphones) to form a microphone array (ie, a microphone array) 202. The microphone array 202 can pick up sounds in various directions around the voice to form a voice analog signal. Compared to a single microphone, the microphone array is able to pick up sound more efficiently and acquire sound information in multiple directions. The sound analog signals in multiple directions are amplified by the signal processing module 204; the processed multi-channel voice analog signals are then subjected to signals by the DSP 206. Analytical processing, the DSP analyzes the signals collected in each direction and sends out the required speaker's voice electrical signal; the voice electrical signal is amplified by a power amplifier, that is, the first power amplifier 208, to drive the rear electromagnetic wire. That is, the electromagnetic transmission line 圏210; the electromagnetic transmission line 圏210 converts the power amplified voice electrical signal into a voice electromagnetic signal, and transmits it outward. The processing of the voice analog signal by the signal processing module 204 and the DSP 206 effectively realizes the processing transition of the voice signal. The electromagnetic wire 圏 can be selected from any wire having a conductive function. Preferably, the electromagnetic wire is wound by an enamel wire. The enameled wire has a small diameter and a small footprint, which can reduce the volume and system load of the mobile terminal. When the electromagnetic wire is wound, the more the number of turns, the stronger the electromagnetic signal is transmitted. Preferably, the number of turns is 20 to 30 inches. The number of turns can generally meet the hearing aid needs of the hearing-impaired population, and can ensure that the volume of the mobile terminal is not excessively occupied. The power amplifier multiplier of the power amplifier and the number of turns of the coil (the electromagnetic signal strength caused by the number of turns) can be appropriately matched by the person skilled in the art according to the actual situation, so that the two are effectively matched. In this way, the mobile phone can pick up the voice of the surrounding speaker and induce the corresponding strong electromagnetic signal with voice frequency through the electromagnetic wire. At the same time, the signal strength can be received by a receiving device within a certain range, and beyond this range, the strength cannot be received by other receivers. Therefore, it has achieved practicality and effectiveness. In order to effectively implement the hearing aid function of the mobile terminal, an earphone capable of receiving an electromagnetic signal transmitted by the mobile terminal is also needed. Hereinafter, in conjunction with FIG. 3, an earphone capable of receiving a voice electromagnetic signal for use with a mobile terminal will be described. Referring to FIG. 3, a schematic structural view of an earphone according to an embodiment of the present invention is shown. The earphone of this embodiment includes: an electromagnetic induction coil (i.e., an electromagnetic receiving coil 302), a power amplifier (i.e., a second power amplifier 304), and a micro receiver 306 (i.e., a microspeaker;). The earphone may be implemented in any suitable form. Preferably, in order to ensure that the earpiece of the earpiece is small in size, concealed, and low in power consumption, an in-ear micro earplug is specially designed with the mobile terminal. The realization principle is that when the mobile phone (mobile terminal) emits an electromagnetic wave with a sound signal, that is, a voice electromagnetic signal, the electromagnetic induction wire 圏 (ie, the electromagnetic receiving wire 圏 302) in the in-ear type earplug can be sensed. The electromagnetic field around it changes and can pick up the electromagnetic wave signal; the signal intensity picked up by the electromagnetic induction line 圏 (ie, the electromagnetic receiving line 圏 302) may be small, so it is not enough to be converted into a sound signal (ie, a voice analog signal) The human ear receives, therefore, the electromagnetic induction line 圏 (ie, the electromagnetic receiving line 圏 302) senses the electromagnetic wave signal, converts it into a voice electrical signal, and sends it to the second pole power amplifier 304, which is the driving amplifier circuit of the rear pole. The second power amplifier 304 performs a certain power amplification on the voice electrical signal. Then, it is sent to the micro-horn of the rear pole, that is, the micro-receiver 306, and the micro-receiver 306 converts the amplified voice electrical signal into a voice analog signal, thereby realizing the reduction of the surrounding sound signal into a voice signal that can be received by the human ear. Received by the human body. At the same time, the power supply of the entire in-ear type earphone is powered by a small button battery. Since the in-ear type miniature earphone has a simple internal processing circuit and low power consumption, the power can be realized by using a small button battery. This design ensures the absolute miniaturization of the in-ear earphones, and can well meet the requirements of hearing aids such as concealment, smallness and wearing comfort. In implementation, the mobile phone shown in FIG. 2 can be used in combination with the open type earplug shown in FIG. 3, and the signal receiving distance of the micro earplug should be within a certain range and cannot be too large to avoid accidentally picking up other signals. Those skilled in the art can use the existing electromagnetic technology according to the actual situation to make a good match between the mobile terminal electromagnetic transmission line 圏 circuit and the micro earphone end electromagnetic receiving line 圏 circuit part. On the other hand, those skilled in the art can use the existing electromagnetic technology according to the actual situation to effectively match the number of end lines transmitted by the mobile phone and the number of turns of the receiving end of the micro earphone with their corresponding matching circuits. It should be noted that the receiving earphone used in conjunction with the mobile terminal of the present invention is not limited to the earphone in the above embodiment, and any suitable earphone that can receive the voice electromagnetic signal can be used together with the mobile terminal that transmits the voice electromagnetic signal, and the present invention There is no limit to this. Of course, the mobile terminal (such as a mobile phone) in the above embodiment can be used normally, and can be set to open the hearing aid function only when working in the hearing aid working mode, and does not affect other normal functions of the mobile phone. The mobile terminal having the hearing aid function emits an electromagnetic wave signal corresponding to the picked up surrounding voice signal, and the electromagnetic wave signal is received by a nearby earphone such as an in-ear micro earplug, and the earplug can restore the mobile terminal part pickup by using the basic principle of the electromagnetic wave. sound signals and transmitted to the human ear by a micro La p VIII. If the Bluetooth wireless function is used instead of the electromagnetic wire, the Bluetooth method is large in size, large in battery, and large in current required for power supply, resulting in large volume and high power consumption. Therefore, when the hearing aid function is realized, The miniaturization, practicability, and commerciality of the mobile terminal hearing aid cannot realize the portability and concealability of the electromagnetic ray to realize the hearing aid function. By using the invention to realize the mobile phone with the hearing aid function and the wireless miniature earplug by the electromagnetic wire ,, the technical effect can fully achieve the required functional effect, and the earplug can be effectively miniaturized, and the hearing aid can be realized in the sound effect receiving. The effect, while retaining the original features of the phone. Therefore, according to the present invention, the realization of the mobile terminal such as the mobile phone can be fully realized, and the operation is simple and effective, and is particularly suitable for the elderly application group and the hearing impaired person, and has very high market value and commercial value. Referring to Figure 4, there is shown a flow chart of the steps of a speech processing method in accordance with an embodiment of the present invention. The voice processing method of this embodiment includes the following steps: Step S402: The mobile terminal converts the voice analog signal into a voice electrical signal, and performs power amplification on the voice electrical signal; the mobile terminal first picks up the voice through a voice receiving device, such as a microphone, to form a voice. Analog signal. Thereafter, the mobile terminal converts the voice analog signal into a voice electrical signal, and then power-amplifies the voice electrical signal through a power amplifying device such as a power amplifier or a power amplifying circuit to drive the electromagnetic transmitting line in the mobile terminal. Step S404: The mobile terminal converts the power amplified voice electrical signal into a voice electromagnetic signal through an electromagnetic transmission line, and transmits the voice electromagnetic signal. The mobile terminal is provided with an electromagnetic transmission line 圏. As a device supporting the hearing aid function, the electromagnetic transmission line converts the voice electrical signal into a voice electromagnetic signal and transmits it outward, so that the device having the voice electromagnetic signal receiving function receives and uses. In the related art, the mobile terminal does not support the hearing aid function, and thus cannot meet the needs of the hearing impaired person to use the mobile terminal. In this embodiment, a magnetic coil is disposed in the mobile terminal, which is used in conjunction with the electromagnetic coil in the receiving device to implement the hearing aid function, thereby realizing the support of the mobile terminal for the hearing aid function. Referring to Figure 5, there is shown a flow chart of the steps of another speech processing method in accordance with an embodiment of the present invention. The voice processing in this embodiment includes both the transmission of the voice signal and the reception of the voice signal, and specifically includes the following steps: Step S502: The mobile terminal converts the voice analog signal into a voice electrical signal, and performs power amplification on the voice electrical signal; In this embodiment, the mobile terminal picks up sound through the microphone array to form a voice analog signal. Afterwards, the mobile terminal converts the voice analog signal into a voice electrical signal through the DSP, and then power-amplifies the voice electrical signal through the first power amplifier to drive the electromagnetic transmission line set in the mobile terminal. Step S504: The mobile terminal converts the power amplified voice electrical signal into a voice electromagnetic signal through an electromagnetic transmission line, and transmits a voice electromagnetic signal to the in-ear micro earplug; In this embodiment, the in-ear micro earplug is used as a voice receiving device, and the earplug is provided with an electromagnetic receiving line 接收 to receive the voice electromagnetic signal emitted by the mobile terminal. The in-ear miniature earphone has a simple internal processing circuit and low power consumption. The power can be realized by using a small button battery, thereby ensuring the miniaturization of the earplug, and the requirements for the hearing aid, such as concealability, smallness, and wearing comfort. . Of course, it is not limited thereto, and other embodiments of the earphone that can receive the voice electromagnetic signal can implement the embodiment.
