Abstract

A wireless microphone transmitter 1 and a wireless microphone receiver 12 can mutually communicate with each other. The wireless microphone receiver 12 transmits level meter data of sound data received by the wireless microphone receiver 12 to the wireless microphone transmitter 1. The wireless microphone transmitter 1 simultaneously displays a transmitter side sound level and a receiver side sound level. The user of the wireless microphone transmitter 1 sees the display of a wireless microphone on hand and can visually monitor the sound of transmission and reception. Instead of the sound level, an RF level may be monitored.

Claims

1. A wireless microphone system comprising a wireless microphone transmitter and a wireless microphone receiver which can mutually communicate with each other, wherein, the wireless microphone transmitter includes:

a sound input unit;

a sound data transmission unit to send an inputted sound to the wireless microphone receiver;

a transmission side level meter data generation unit to generate level meter data of transmission side monitoring;

a level meter data reception unit to receive level meter data of reception side monitoring from the wireless microphone receiver side; and

a level meter display unit to display the level meter data of the transmission side monitoring generated by the transmission side level meter data generation unit and the level meter data of the reception side monitoring received by the level meter data reception unit, and

the wireless microphone receiver includes;

a sound data reception unit;

a reception side level meter data generation unit to generate the level meter data of the reception side monitoring; and

a level meter data transmission unit to transmit the level meter data of the reception side monitoring generated by the reception side level meter data generation unit to the wireless microphone transmitter side.

2. The wireless microphone system according to claim 1, wherein the transmission side level meter data generation unit includes a filter unit to convert sound data inputted from the sound input unit into the level meter data, and the reception side level meter data generation unit includes a filter unit to convert received sound data into the level meter data.

3. The wireless microphone system according to claim 1, wherein the wireless microphone transmitter includes a transmission RF level detection unit to detect a transmission RF level of the sound data transmission unit, the transmission side level meter data generation unit includes a filter unit to convert the transmission RF level into the level meter data, the wireless microphone receiver includes a reception RF level detection unit to detect a reception RF level of the sound data reception unit, and the reception side level meter data generation unit includes a filter unit to convert the reception RF level into the level meter data.

4. The wireless microphone system according to claim 1, wherein the wireless microphone transmitter includes a transmission data level meter display unit and a reception data level meter display unit as the level meter display unit, and includes, at a front stage of the transmission data level meter display unit, a delay unit to delay displaying the level meter data of the transmission side monitoring onto the transmission data level meter display unit by a delay time corresponding to a transmission/reception time between the wireless microphone transmitter and the wireless microphone receiver.

5. The wireless microphone system according to claim 1, wherein the wireless microphone receiver includes a subtraction unit to subtract the level meter data of the reception side monitoring received by the level meter data reception unit from the level meter data of the transmission side monitoring generated by the transmission side level meter data generation unit, and the level meter display unit displays difference data acquired by the subtraction unit.

6. A wireless microphone system comprising a wireless microphone transmitter and a wireless microphone receiver which can mutually communicate with each other, wherein, the wireless microphone transmitter includes:

a sound input unit;

a sound data transmission unit to send an inputted sound to the wireless microphone receiver;

a transmission side level meter data generation unit to generate level meter data of transmission side monitoring;

a level meter data reception unit to receive level meter data of reception side monitoring from the wireless microphone receiver side;

a subtraction unit to subtract the level meter data of the reception side monitoring received by the level meter data reception unit from the level meter data of the transmission side monitoring generated by the transmission side level meter data generation unit; and

a difference amount display unit to display difference data acquired by the subtraction unit, and

the wireless microphone receiver includes;

a sound data reception unit;

a reception side level meter data generation unit to generate the level meter data of the reception side monitoring; and

a level meter data transmission unit to transmit the level meter data of the reception side monitoring generated by the reception side level meter data generation unit to the wireless microphone transmitter side.

7. A wireless microphone transmitter which, together with a wireless microphone receiver, constitutes a wireless microphone system and can mutually communicate with the wireless microphone receiver, the wireless microphone transmitter comprising:

a sound input unit;

a sound data transmission unit to send an inputted sound to the wireless microphone receiver;

a transmission side level meter data generation unit to generate level meter data of transmission side monitoring;

a level meter data reception unit to receive level meter data of reception side monitoring from the wireless microphone receiver side; and

a level meter display unit to display the level meter data of the transmission side monitoring generated by the transmission side level meter data, generation unit and the level meter data of the reception side monitoring received by the level meter data reception unit.
