     The exemplary embodiments of the present invention will be specifically described with reference to the accompanying drawings. 
     As illustrated in  FIGS. 1 to 6 , a rechargeable dual massage apparatus according to the present invention includes a housing  100 , a soft cap  200 , a strong vibrator  300 , a weak vibrator  400 , a charging terminal  500 , a rechargeable battery  600 , a volume switch  700 , and a control unit  800 . 
     The housing  100  includes a head portion  110  at a front side of the housing  100 , and a handle portion  120  at a rear side of the head portion  110 , and the housing  100  is made of a typical synthetic resin material having high durability. 
     In this case, the charging terminal  500 , the volume switch  700 , and a lamp  900  or a buzzer  1000 , which will be described below, are installed at one side of the housing  100 , and the rechargeable battery  600  and the control unit  800 , together with the strong vibrator  300 , are installed in the housing  100 . Meanwhile, the weak vibrator  400  to be described below is installed at a rear side of the handle portion  120  of the housing  100 . 
     The soft cap  200  is coupled to a rear end of the handle portion  120 , and extends and protrudes from the handle portion  120 . That is, the soft cap  200  is made of a silicone material so that a user may softly massage, for example, the face or the scalp by using vibration generated in the soft cap  200  while directly rubbing the face or the scalp with the soft cap  200 . 
     As an exemplary embodiment, as illustrated in  FIG. 6 , the soft cap  200  includes an auxiliary massaging member  210  for massaging the face or the scalp in a state in which the auxiliary massaging member  210  is fitted into the soft cap  200 . As illustrated in the drawing, the auxiliary massaging member  210  is formed in the form of a ring so as to be fitted into the soft cap  200 , and may have an acupressure protrusions formed at one side so as to massage the scalp, and a cushion formed at the other side so as to massage the face. 
     The strong vibrator  300  is installed in the head portion  110  of the housing  100 , and a massaging member  310  for massaging the body is detachably coupled to the strong vibrator  300  at a lower side of the head portion  110 . That is, like a typical massage apparatus, the strong vibrator  300  is used to massage the abdomen, the shoulder, the back, the arms, the legs, and the like, and configured to generate strong vibration suitable for the massage. 
     The weak vibrator  400  is coupled to the rear side of the handle portion  120  of the housing  100 , the handle portion  120  of the housing  100 , and configured to transmit vibration to the soft cap  200 . That is, the weak vibrator  400  is used to massage sensitive parts such as the face or the scalp, and configured to generate weak vibration suitable for the massage. 
     The charging terminal  500  is installed on the housing  100 , and configured such that a terminal pin of a charging adapter including a plug is fitted into the charging terminal  500  so that the charging terminal  500  may be supplied with electric power from a commercially available power source. 
     The rechargeable battery  600  is installed in the housing  100 , and configured to be charged with electric power through the charging terminal  500  and to supply electric power to the strong vibrator  300  and the weak vibrator  400 . A lithium-ion battery is used as the rechargeable battery  600 , and thus the rechargeable battery  600  may be continuously used, for example, for over two hours after being charged for two hours. 
     The volume switch  700  is installed on the housing  100 , and configured to turn on or off the power source by being rotated, and to adjust intensity of the strong vibrator  300  or the weak vibrator  400  in a stepless manner after turning on the power source. That is, the volume switch  700  may softly and precisely adjust intensity of the strong vibrator and the weak vibrator without impact, thereby improving convenience for use. 
     The control unit  800  is installed in the housing  100 , and operates the strong vibrator  300  or the weak vibrator  400  in accordance with the on/off operation of the volume switch  700 , such that the strong vibrator  300  operates when the volume switch  700  adjusts intensity within a predetermined time in a state in which the volume switch  700  is turned on, and the weak vibrator  400  operates when the volume switch  700  adjusts intensity after a predetermined time has passed in a state in which the volume switch  700  is turned on. That is, the control unit  800  controls a circuit so as to adjust both of the strong vibrator  300  and the weak vibrator  400  by using the single volume switch  700 , and for example, in order to use the strong vibrator  300 , the user rotates the volume switch to increase intensity before one minute passes after the user rotates the volume switch to turn on the volume switch  700 , and in order to use the weak vibrator  400 , the user rotates the volume switch to adjust intensity after one minute has passed after the user rotates the volume switch to turn on the volume switch  700 . In order to use the strong vibrator  300  after using the weak vibrator  400 , the user turns off the volume switch  700 , and then uses the strong vibrator  300  again. 
     In this configuration, the lamp  900  is installed on the housing  100  in order to indicate a charging state or an operating state of the rechargeable battery  600 . For example, the lamp  900  emits red light while the adapter is plugged into the charging terminal  500  and the rechargeable battery  600  is charged, and the lamp  900  emits green light when the rechargeable battery  600  is completely charged. In addition, the lamp  900  is turned off in a state in which the volume switch  700  is turned off, and the lamp  900  may emit yellow light in a state in which the volume switch  700  is turned on. 
     In addition, the buzzer  1000  may be installed on the housing  100  so as to inform that a predetermined time has passed in a state in which the volume switch  700  is turned on. That is, the buzzer  1000  serves to inform the user of a point in time when the operation is changed to the weak vibrator  400 . 
     According to the configuration of the present invention, since the rechargeable dual massage apparatus may be used in a wireless state after being charged, the user may more conveniently use the rechargeable dual massage apparatus without being restricted by location and movement, and since both of the strong vibrator and the weak vibrator, which have different intensities, are installed at the front and rear sides of the handle portion so as to enable the user to selectively use the strong vibrator and the weak vibrator, the user may softly massage sensitive body parts such as the face or the scalp as well as the abdomen, the back, the arms, and the legs. 
     While the present invention has been described by the limited exemplary embodiments as described above, the technical spirit of the present invention is defined by the claims.
