    • A method for changing reproduction speed of speech sound, includes the steps of: storing an input sound signal in a buffer; leaving a sound signal from the buffer as it is or extending the sound signal from the buffer in a sound section where a power of the input sound signal exceeds a threshold value; leaving the sound signal from the buffer as it is, compressing the sound signal from the buffer, or extending the sound signal from the buffer, in a no-sound section, so that the reproduction speed of speech sound is changed; wherein a speech head protection section is set prior to the sound section being set to be a storing amount of the buffer limited by a designated limited value; and compression or deletion of the sound signal is adjusted by a compression ratio or prevented if there is the sound section in the speech head protection section, so that speech head protection is performed.
    • 一种用于改变语音的再现速度的方法,包括以下步骤:将输入声音信号存储在缓冲器中; 从缓冲器中留下声音信号,或者在输入声音信号的功率超过阈值的声音部分中从缓冲器延伸声音信号; 离开缓冲器的声音信号,在无声部分中压缩来自缓冲器的声音信号或者将声音信号从缓冲器延伸,使得语音的再现速度改变; 其中在所述声音部分被设置为被指定的限制值限制的所述缓冲器的存储量之前设置话音头保护部分; 并且通过压缩比调节声音信号的压缩或删除,或者如果在话音头保护部分中存在声音部分,则防止声音信号的压缩或删除,从而执行语音头保护。

    • A collapsable portable wireless unit (100) comprises an upper case (101) and a lower case (102) coupled through a hinge member (103) to open/close freely. A planar conductor (105) is arranged on the upper case (101). First and second power supply sections (111, 112, 103) are arranged on the planar conductor (105) at a specified interval. A harmonic signal distributor (120) is arranged on a circuit board (110) provided in the lower case (102) and distributes a harmonic signal to the first and second power supply sections (111, 112, 103). A phase shifter (121) sets the exciting phase of the harmonic signal in the second power supply sections (112, 103) at a value different from that of the exciting phase of the harmonic signal in the first power supply sections (111, 103).
