The through holes 131a and 131b are on the opposite side of the speaker hole 120 across the center of the speaker 11, and are symmetric with respect to each other (a line symmetric position with respect to a straight line passing through the center of the speaker 11 and parallel to the y axis). ).

  FIG. 8 is an enlarged view showing a cross section taken along line II of FIG. 2 according to the embodiment. FIG. 9 is an enlarged view showing a cross section taken along line II-II in FIG. 2 according to the embodiment.

  As shown in FIG. 8, by attaching the speaker 11 to the speaker storage unit 140, an air chamber 500 is formed between the speaker 11 and the inner wall surface of the front case 100. The through holes 131 a and 131 b communicate with the air chamber 500 from the outside of the housing 300. Further, as shown in FIG. 9, the speaker hole 120 provided in the front case 100 also communicates with the air chamber 500 from the outside of the housing 300, similarly to the through holes 131a and 131b.

  A built-in speaker housed in a housing or the like may cause a sound shift or abnormal noise due to a rolling phenomenon in which a diaphragm vibrates unevenly. In order to prevent the occurrence of the rolling phenomenon, it is necessary to vibrate the diaphragm as uniformly as possible. In order to vibrate the diaphragm as uniformly as possible, it is preferable to provide a speaker hole directly above and near the center of the diaphragm of the speaker. However, when the keypad 3, the display 4, and the speaker 11 with an effective vibration radius φ of 18 mm or more are mounted as in the communication device 1, the trueness of the speaker 11 is restricted due to restrictions in housing design and design convenience. It is difficult to provide the speaker hole 120 on the top. For this reason, for example, as shown in FIG. 2, the communication device 1 is provided with a speaker hole 120 below the keypad 3 (on the negative direction side of the y-axis shown in FIG. 1). Since the position of the speaker hole 120 shown in FIG. 2 is not directly above the diaphragm of the speaker 11, there is a possibility that the vibration of the diaphragm becomes non-uniform as it is. Therefore, the communication device 1 provides through holes 131 a and 131 b in the speaker storage unit 140, and ensures another hole other than the speaker hole 120 as an air hole from the air chamber 500. As a result, the communication device 1 can vibrate the diaphragm of the speaker 11 more uniformly as compared with the case where the air hole from the air chamber 500 is only the speaker hole 120. In addition, by providing the through holes 131a and 131b in the speaker storage unit 140, the sound output to the outside from the speaker holes 120 is output from the through holes 131a and 131b, so that the sound is reliably output to the outside. It is also expected to be effective.

  In the example shown in FIG. 8 and FIG. 9, the communication device 1 is moved from the air chamber 500 to the casing in a symmetrical position (a position symmetrical with respect to a straight line passing through the center of the speaker 11 and parallel to the y axis). Although two through holes 131a and 131b communicating with the outside of 300 are provided, the present invention is not limited to this example. For example, the communication device 1 may include one through hole at a position opposite to the speaker hole 120 across the center of the speaker 11.

Following the input of the transmitted voice, the processor 10 executes a noise canceling process of the received voice signal based on the input of the microphone 2C (step S103), and outputs the received voice from the speaker 11 (step S104). .

  Following the output of the received voice, the processor 10 determines whether or not the call is finished (step S105).

  As a result of the determination, the processor 10 ends the processing shown in FIG. 11 when the call is ended (step S105, Yes).

  As a result of the determination, the processor 10 returns to the determination in step S101 when the call has not ended (No in step S105).

  In step S101, if the result of determination is that the call is not a hands-free call or PTT (step S101, No), the processor 10 inputs the transmitted voice from the microphone 2B (step S106). Following the input of the transmitted voice, the processor 10 executes a noise canceling process of the received voice signal based on the input of the microphone 2C (step S107), and outputs the received voice from the receiver 7 (step S108). . After outputting the received voice, the processor 10 moves to the determination in step S105.

  In the example shown in FIG. 11, a case has been described in which both microphones that collect transmission voices in hands-free calling and PTT are the microphones 2A, but in the following, using hands-free calling and PTT, FIG. A case will be described in which the microphones collecting the transmitted voice are different from each other.

  As shown in FIG. 12, the processor 10 determines whether the call is a hands-free call (step S201).

  When the result of the determination is that the call is a hands-free call (step S201, Yes), the processor 10 inputs the transmitted voice from the microphone 2A (step S202). Following the input of the transmitted voice, the processor 10 executes a noise canceling process for the received voice signal based on the input of the microphone 2C (step S203), and outputs the received voice from the speaker 11 (step S204). .

  Following the output of the received voice, the processor 10 determines whether or not the call is finished (step S205).

  As a result of the determination, the processor 10 ends the process shown in FIG. 12 when the call is ended (step S205, Yes).

  As a result of the determination, the processor 10 returns to the determination in step S201 if the call has not ended (No in step S205).

  In step S201, if the result of determination is that the call is not a hands-free call (step S201, No), the processor 10 determines whether it is PTT (step S206).

  If the result of determination is PTT (step S206, Yes), the processor 10 inputs the transmitted voice from the microphone 2B (step S207). Following the input of the transmitted voice, the processor 10 executes noise canceling processing of the received voice signal based on the input of the microphone 2C (step S208), and outputs the received voice from the speaker 11 (step S209). . After outputting the received voice, the processor 10 moves to the determination in step S205.

  In step S206, if the result of determination is not PTT (No in step S206), the processor 10 is a normal call, and therefore, inputs the transmitted voice from the microphone 2B (step S210). Following the input of the transmitted voice, the processor 10 executes a noise canceling process for the received voice signal based on the input of the microphone 2C (step S211), and outputs the received voice from the receiver 7 (step S212). . After outputting the received voice, the processor 10 moves to the determination in step S205.

  In the example shown in FIGS. 11 and 12, the processor 10 uses the microphone 2A in the case of a hands-free call and PTT, and uses the microphone 2B in the case of a normal call. In this way, the communication device 1 can use different microphones for collecting transmitted voices according to the method of calling. In the example shown in FIGS. 11 and 12, the processor 10 performs noise canceling processing on the received voice signal based on the input of the microphone 2C in any of the hands-free call, PTT, and normal call. Execute. For this reason, the communication device 1 can reduce the noise of the received voice regardless of the call method.

  Conventionally, during a hands-free call, the output volume of the speaker is increased and the sensitivity of the microphone is increased. As a result, the sound output from the speaker is collected by the microphone, resulting in an echo, It is a hindrance. Therefore, in conventional equipment such as a mobile phone equipped with a double microphone, from the viewpoint of preventing echo during hands-free calling, for example, for noise canceling processing provided on the surface opposite to the sound emitting surface of the speaker The microphone is used to collect the transmitted voice during a hands-free call. For this reason, conventionally, noise canceling processing for hands-free calls has to be sacrificed.

  On the other hand, according to the communication device 1 according to the embodiment, in the case of a hands-free call, the transmission sound is collected by the microphone 2A and the sound collection for the noise canceling process is performed by the microphone 2C. . Furthermore, the communication device 1 is configured so that the distance between the microphone 2A, the microphone 2B, and the speaker 11 is longer than the distance between the microphone 2B and the speaker hole 120. The microphone 2A, the microphone 2B, and the speaker 11 are provided on the front case 100 by adjusting the positional relationship between them (see FIG. 2). The communication device 1 can reduce the echo during the hands-free call as much as possible by collecting the transmitted voice during the hands-free call using the microphone 2A that is farther from the speaker 11 than the microphone 2B. Furthermore, since the communication device 1 can continue to use the microphone 2C as a microphone for collecting noise canceling processing during a hands-free call, the noise canceling processing during the hands-free call is sacrificed. This eliminates the need to perform noise canceling processing during a hands-free call. Thus, the communication device 1 according to the embodiment can improve convenience.

  In addition, since the communication device 1 uses the microphone 2A provided on the outer wall surface of the housing 300 during the hands-free call to collect the transmitted voice during the call, the communication device 1 collects the sound using the microphone 2B. The sound collection performance tends to improve rather than

  As shown in FIG. 11, the communication device 1 can collect the transmitted voice uttered toward the housing 300 with the microphone 2 </ b> A while operating the transmission key 22 during PTT. Thereby, for example, it is possible to provide a user with a usage form similar to a wireless device that performs voice transmission by performing predetermined key operations. On the other hand, as shown in FIG. 12, the communication device 1 can also collect the transmitted voice uttered toward the housing 300 by the microphone 2B while operating the transmission key 22 during PTT. . Thereby, it is easy to deal with a usage mode of a user who tends to pronounce toward the microphone 2B at the time of voice input.
