  However, all of the above-mentioned various configurations are temporarily unable to recognize speech when the head is lifted from the pillow or the receiver unit of the headphones is removed due to the nature as a bone conduction speaker. For example, when you get up from the pillow and operate the connected sound source, there is an inconvenience that you can not check the operation result unless you put your head on the pillow again, and when you get up temporarily during use However, since voice recognition was interrupted, there was a drawback of missing music. And since it is a bone conduction, naturally the sound can be heard only by the person himself and cannot be heard by the people around.

  The present invention has been made paying attention to the above circumstances, and by providing an air conduction speaker in the bone conduction speaker device, the output of each speaker can be switched to the bone conduction or air conduction speaker according to the use situation. The present invention provides a bone conduction speaker device that can improve music and listen to music and the like.

  In order to solve the above problems, a bone conduction speaker device according to the present invention is a bone conduction speaker device in which a bone conduction speaker that outputs sound vibration based on a signal input from a voice input means to a control circuit is arranged on the surface of an elastic cushion. An air conduction speaker is provided on the surface of the speaker device spaced apart from the bone conduction speaker.

  According to the present invention, it is possible to output from a bone conduction speaker and / or an air conduction speaker according to usage conditions, such as the use state of the listener and consideration to the surroundings, and bone conduction with improved usability. A speaker device can be obtained.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. A pillow (2) incorporating a bone conduction speaker device (1) shown in a perspective view in FIG. 1 and a longitudinal sectional view in FIG. 2 includes an elastic cushion body (4) having a bone conduction speaker (3) disposed on the upper surface, An audio receiving device is constituted by a cover (5) and the like covering these. The bone conduction speaker (3) directly transmits the sound from the sound source as sound vibration to the listener's head (6) so that even a deaf person can be heard by bone conduction. The number of speakers (3) should be at least two so that at least one of them touches the head when lying down, at a predetermined interval along the longitudinal direction in the substantially central recess of the upper surface of the elastic cushion body (4). It is arranged.

  Cases (7) and (7 ') are arranged on the left and right of the upper surface of the elastic cushion body (4), and an air conduction speaker (8) that emits sound in the air in the cases (7) and (7'). (8) and the drive circuits of the speaker control units (9) and (9) are arranged, and on the side of one case (7) is an operation unit (10) for turning on / off the power and an audio input unit (11 ) Is installed. On the side surface of the other case (7 '), there is provided a changeover switch (12) for switching the output to the bone conduction speaker (3) and the air conduction speaker (8).

  FIG. 3 is a block diagram showing a transmitting / receiving device of the bone conduction speaker device (1), and an audio signal from a sound source (13) (13 ′) such as a television or a CD radio cassette is inputted to the input unit (11), The bone conduction speakers (3) and (3) and the air conduction speakers (8) and (8) are driven by the drive circuit of the speaker controller (9).

  The output is switched to the bone conduction speaker (3) and the air conduction speaker (8) by the connecting operation by sliding the selector switch (12) in the direction of the arrow in the figure, and only to the bone conduction speaker (3) (3). Mode (A) for output operation, output mode (B) for only air conduction speakers (8) and (8), and mode (C) for output to speakers (3) and (8) for both bone conduction and orbit. It is configured so that it can be used by switching.

  With the above configuration, for example, as shown in FIG. 2, the listener puts the head (6) on the pillow (2) containing the bone conduction speaker device (1) and turns on the power source. ) Is transmitted to the speaker control unit (9), and is transmitted to the head (6) as a sound vibration from the bone conduction speaker (3). And can listen to music.

  Therefore, it is used in the mode (A) in which only the bone conduction speaker (3) is operated at the time of use when consideration should be given to sound leakage to the surroundings, such as use before going to bed, and not alone. When listening with other listeners, the mode (B) of the air conduction speaker (8) only is operated, and in addition, when other users listen and voice is heard by bone conduction, If both the bone conduction speaker (3) and the air conduction speaker (8) are operated (C), a plurality of persons including the deaf person can share the same sound atmosphere at the same time, and the use situation can be dealt with. Various modes can be easily switched and selected.

  Further, when operating the sound source (13) such as radio tuning in the mode (A) in which only the bone conduction speaker (3) is operated to listen to music such as during use before going to bed, By switching to the (B) or (C) mode, the operation can be performed while monitoring the sound from the air conduction speaker (8). Note that when operating in a wireless system using radio waves, infrared LEDs, or the like, it can be used as a wireless speaker in the (B) mode.

  Next, another embodiment of the present invention will be described. The pillow (22) incorporating the bone conduction speaker device (21) shown in FIG. 4 with the same reference numerals as those in FIG. 1 has an elastic cushion together with the bone conduction speaker (3) arranged in the same manner as in the above embodiment. Driving circuits for the air conduction speakers (8) and (8) and the speaker control units (9) and (9) are arranged on the left and right of the upper surface of the body (4), and the bone conduction speakers (3) and (3). Is provided with a detection switch (15) that detects the load when the head (6) is placed on the elastic cushion body (4) and is biased.

  Then, as shown in the block diagram of FIG. 5, when the head is placed on the pillow (21), the detection switch (15) detects this and switches the changeover switch (12) as shown by the solid line. The bone conduction speaker (3) is driven by the drive circuit of the control unit (9), so that the user can listen to the sound without worrying about sound leakage to the surroundings.

  When the detection switch (15) does not detect the load, such as when the head is not placed on the elastic cushion (4) or the head is separated from the pillow (22), the changeover switch (12) is switched to the dotted line state. , Switching to driving of the air conduction speaker (8). Therefore, when you wake up due to radio tuning operations, etc., the speaker output is automatically switched and sound is generated from the air conduction speaker (8), so the sound that was listening to the bone conduction speaker (3) is interrupted. This eliminates the problem of making it possible to listen to the sound continuously.

  FIG. 6 shows the bone conduction speaker device (31) according to the above-described embodiment disposed in the headphone (32), on the inner surface side that is the side surface of the head of the elastic cushion portion (34) forming the receiver portion. Bone conduction speakers (3) and (3) are arranged, and air conduction speakers (8) and (8) are arranged on the opposite outer surface side. A detection switch (15) is provided below the inner surface close to the bone conduction speaker (3) to detect and abut on the head surface when the headphones (32) are worn. When the user wears the headphones (32), music or the like can be heard from the bone conduction speaker (31) by detection of the detection switch (15).

  In addition, the headphone (32) is removed from the head, and the headphone (32) is stored and disposed in the storage case (35) as shown in FIG. 7 with the air conduction speaker (8) portion of the receiver facing upward. As a result, the detection switch (15) is de-energized to generate sound from the speakers (8) and (8) by air conduction, and the headphones (32) can be used as a normal air conduction speaker.

  The present invention can be used not only as a bone conduction speaker but also as a bone conduction speaker device capable of listening to sound from an air conduction speaker.
