A wearable speaker system includes an enclosure, in which a first speaker unit and a first opening portion that is an end of a first bass reflex duct are disposed in a first end region of the enclosure, in which a second speaker unit and a second opening portion that is an end of a second bass reflex duct are disposed in a second end region, in which each of the first and second speaker units and includes a speaker and a passive radiator that faces in an opposite direction from the speaker, and in which a space between the speaker and the passive radiator included in each of the first and second speaker units and is connected to a space in the enclosure.

Wearable speaker system

To provide a wearable speaker system that can obtain a higher sense of presence through reproduction of bass. A wearable speaker system includes an extendable bellows tube including a first end and a second end; a first speaker unit which is connected to the first end and of which an inside communicates with an inside of the bellows tube; a second speaker unit which is connected to the second end and of which an inside communicates with the inside of the bellows tube; a first bass reflex duct having one end that is open to an outside in the first speaker unit and the other end that is open to the inside of the bellows tube; and a second bass reflex duct having one end that is open to the outside in the second speaker unit and the other end that is open to the inside of the bellows tube.

The subject of the present invention is for offering an operation equipment and an operation system that can select directly either of a plurality of indication keys arranged on an operation screen according to posture of an equipment. An inclination of operation equipmentis detected, and the posture signal is made to output by inclination angle detection part; the rotation angle of the X-axis and the Y-axis which perpendicularly intersect in parallel, mutually, with the main surface part based on the posture signal by coordinates conversion partis made to compute as an X-axis rotation angle and a Y-axis rotation angle, respectively; while memorizing a cell information, which is made of the plurality of cells, in cell information memory part, a conversion table which corresponds each cell of cell information with the indication key is memorized in conversion table memory part; while specifying one cell in cell information as a current cell based on the X-axis rotation angle and the Y-axis rotation angle by cursor control part, the indication key, which is corresponded to the current cell, is specified by using the conversion table, and a cursor is made to be moved.

Operation equipment and operation system

When digital audio data is input, the data is temporarily stored in a ring buffer memory. A clock generator adjusts an output transfer clock cycle so that the difference between the count of an address counter for writing data and the count of an address counter for reading data always falls within a predetermined range. An input rate calculating circuit calculates an average transfer rate at which the input data is transferred. The clock generator increases or decreases the transfer rate of the output data so that the average transfer rate of the output data becomes equal to the average transfer rate of the input data. Consequently, a fluctuation of the transfer rate of the output data is prevented, and thus deterioration of the quality of output signals of digital data is prevented. Moreover, reproduction of output signals becomes available with the use of a synchronous sampling rate converter.

Digital data buffering device

In a data recording apparatus which sequentially records recording data on a magnetic tape (T), when a plurality of continuously recorded data files F(i) are rewritten into new data files F(I) having smaller data quantities, recording areas which remain without being rewritten into the new data files F(I) are rewritten into unrecorded areas NR containing no data. Further, when rewriting into new data files G(I) which have larger data quantities, reserve areas SP are provided, in which data has not been previously recorded, and overflow data is written into the reserve areas SP at the time of rewriting. Furthermore, when rewriting into a new data file H(I) having a larger quantity, in a case where the data file H(i+1) following the rewritten data file H(i) is not needed, the recording areas of the unnecessary data file H(i+1) which are not rewritten, are rewritten into a new data file H(I+1) having no data, or are rewritten into the above mentioned reserve areas SP belonging to a newly rewritten data file A(I).

A phase control circuit adjusts the width of a PLL clock signal so that a PLL clock signal generated from a master clock signal MCK is in synchronization with an EFM signal. A velocity detector detects offset in velocity by counting a pulse width of an EFM signal with a master clock signal MCK. The phase control circuit alters the pulse width of a PLL clock signal according to the detected offset in velocity to alter the average frequency of a PLL clock signal in proportion to offset of the rotational speed.

Digital PLL circuit

In a data recording and reproducing apparatus for writing the video signals read out from a magnetic tape (11) alternately into image memories, and reading out and reproducing the video signals from the image memory not used for writing video signals, the video signal read out from the image memory when the memory indication switch (SW1) is manipulated is directly held in the image memory, and when reproducing the video signal executed in succession, using the image memory in which video signals is not preserved, writing of video signal from the magnetic tape (11) into image memory and reading from the image memory are effected. In this reproducing action, when the reproduction indication switch (SW2) is manipulated, and previously preserved video signal is read out from the image memory and reproduced. Therefore, by keeping the video signal desired to be reproduced frequently in the image memory, it may be reproduced as required, and therefore the waiting time until the desired video signal is displayed may be notably shortened.

In a high-speed dubbing method, calculations are executed to find waiting time by which the amount of remaining audio data stored in a memory is minimized upon completion of a data transferring process to the next recordable area, and by stopping the recording operation for the waiting time, the amount of the remaining audio data in the memory is always kept minimum, immediately before the accessing process and the track jumping process with respect to the next recordable area. Therefore, even if any disturbance occurs during the dubbing operation with respect to a plurality of intermittent recordable areas, it is possible to eliminate the overflow of the audio data, and to improve the reliability of the dubbing operation.

A TOC region is provided on a DAT tape. In the TOC region reduced still image data is recorded as one still image and is obtained by reducing each still picture data recorded in each of a plurality of still picture/audio composite data regions provided subsequently to the TOC region. A first address of each still picture/audio composite data is also recorded in the TOC region. At the time of reproduction, the TOC region is reproduced and the still image based on the reduced still image data is shown on a display. When an operator selects a specific still image among the plurality of displayed still pictures, the corresponding still picture/audio composite data is reproduced based on an address corresponding to the selected still picture.
